Spring Security+Hibernate記住我實例

本教程介紹了使用Spring Security與Hibernate實現"記住我"認證功能。

"記住我" 是持久登錄認證，應用程序會記住會話用戶的身份。基本上，在登錄時當你使用"記住我"功能支持，應用程序會將一個cookie在登錄成功後發送到瀏覽器。這個 cookie 將被存儲在瀏覽器端，並繼續在一定期限(由cookie生命過期時間定義)。 下一次，當您嘗試訪問該應用程序，瀏覽器將檢測到的cookie(如果仍然有效)那麼些用戶將會自動登錄，無需提供如用戶ID/密碼。

Spring Security提供了兩種 「記住我」的實現：

• 簡單基於散列標記的方法：它使用散列來保護基於cookie標記的安全性

• 持久化標記方法：它使用一個數據庫或其他持久化存儲機制來保存生成的標記

在這篇文章中，我們將討論關於持久化標記方法

相對於正常登錄教程文章作了一些以下的修改：

1.持久化標記方法，數據庫中添加一個名爲：persistent_logins 的表，可以創建使用下面的SQL：

CREATE TABLE persistent_logins (
username VARCHAR(64) NOT NULL,
series VARCHAR(64) NOT NULL,
token VARCHAR(64) NOT NULL,
last_used TIMESTAMP NOT NULL,
PRIMARY KEY (series)
); 

此表包含用戶名，「記住我」的最後一次活動時間(last_used時間戳)，Bcrypt內部實現安全令牌和一系列信息。 

2.在Spring Security配置"記住我"

package com.yiibai.springsecurity.configuration;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.authentication.rememberme.JdbcTokenRepositoryImpl;
import org.springframework.security.web.authentication.rememberme.PersistentTokenRepository;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

@Autowired
@Qualifier("customUserDetailsService")
UserDetailsService userDetailsService;

@Autowired
DataSource dataSource;

@Autowired
public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(userDetailsService);
}

@Override
protected void configure(HttpSecurity http) throws Exception {
  http.authorizeRequests()
      .antMatchers("/", "/home").permitAll()
      .antMatchers("/admin/\*\*").access("hasRole('ADMIN')")
      .antMatchers("/db/\*\*").access("hasRole('ADMIN') and hasRole('DBA')")
      .and().formLogin().loginPage("/login")
      .usernameParameter("ssoId").passwordParameter("password")
      .and().rememberMe().rememberMeParameter("remember-me").tokenRepository(persistentTokenRepository()).tokenValiditySeconds(86400)
      .and().csrf()
      .and().exceptionHandling().accessDeniedPage("/Access\_Denied");
}

@Bean
public PersistentTokenRepository persistentTokenRepository() {
    JdbcTokenRepositoryImpl tokenRepositoryImpl = new JdbcTokenRepositoryImpl();
    tokenRepositoryImpl.setDataSource(dataSource);
    return tokenRepositoryImpl;
}

} 

請注意，我們可調用 rememberMe() 來配置記住我，在視圖中提供一個「記住我」複選框身份驗證的HTTP參數名稱(我們將在視圖中看到)。我們還指定要使用 tokenRepository(令牌將被存儲)，並將該令牌的時間(以秒爲單位)仍然有效。要配置存儲庫時我們要注入了一個數據源。

這是所有你需要激活"記住我"，在Spring Security基礎的應用程序中。

或者，可以使用 Spring Security內置表達以及Spring security標籤在您的視圖根據特定的邏輯定製/顯示/隱藏 "記住我"或使用安全認證。

注意：如果你不願意使用JDBC，可能在應用程序是基於Hibernate，現在你可以參考 Spring MVC+Spring Security+hibernate實例，在這裏我創建了一個基於Hibernate實現PersistentTokenRepository，它被命名爲 HibernateTokenRepositoryImpl。

以上安全配置以XML配置格式爲：

<beans:beans xmlns="http://www.springframework.org/schema/security"
xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-4.0.xsd">

<http auto-config="true" >
    <intercept-url pattern="/" access="permitAll" />
    <intercept-url pattern="/home" access="permitAll" />
    <intercept-url pattern="/admin\*\*" access="hasRole('ADMIN')" />
    <intercept-url pattern="/dba\*\*" access="hasRole('ADMIN') and hasRole('DBA')" />
    <form-login  login-page="/login" 
                 username-parameter="ssoId" 
                 password-parameter="password" 
                 authentication-failure-url="/Access\_Denied" />
    <csrf/>
</http>

<authentication-manager >
    <authentication-provider user-service-ref="customUserDetailsService"/>
</authentication-manager>

<remember-me 
    remember-me-parameter="remember-me"
    remember-me-cookie="remember-me"
    token-validity-seconds="86400"
data-source-ref="dataSource" />

<beans:bean id="customUserDetailsService" class="com.yiibai.springsecurity.service.CustomUserDetailsService" />

完整的代碼示例如下所示。

數據庫表部分

第3步：創建數據庫模式並填充數據

/* For Remember-Me token storage purpose */
CREATE TABLE persistent_logins (
username VARCHAR(64) NOT NULL,
series VARCHAR(64) NOT NULL,
token VARCHAR(64) NOT NULL,
last_used TIMESTAMP NOT NULL,
PRIMARY KEY (series)
);

/*All User's gets stored in APP_USER table*/
create table APP_USER (
id BIGINT NOT NULL AUTO_INCREMENT,
sso_id VARCHAR(30) NOT NULL,
password VARCHAR(100) NOT NULL,
first_name VARCHAR(30) NOT NULL,
last_name VARCHAR(30) NOT NULL,
email VARCHAR(30) NOT NULL,
state VARCHAR(30) NOT NULL,
PRIMARY KEY (id),
UNIQUE (sso_id)
);

/* USER_PROFILE table contains all possible roles */
create table USER_PROFILE(
id BIGINT NOT NULL AUTO_INCREMENT,
type VARCHAR(30) NOT NULL,
PRIMARY KEY (id),
UNIQUE (type)
);

/* JOIN TABLE for MANY-TO-MANY relationship*/
CREATE TABLE APP_USER_USER_PROFILE (
user_id BIGINT NOT NULL,
user_profile_id BIGINT NOT NULL,
PRIMARY KEY (user_id, user_profile_id),
CONSTRAINT FK_APP_USER FOREIGN KEY (user_id) REFERENCES APP_USER (id),
CONSTRAINT FK_USER_PROFILE FOREIGN KEY (user_profile_id) REFERENCES USER_PROFILE (id)
);

/* Populate USER_PROFILE Table */
INSERT INTO USER_PROFILE(type)
VALUES ('USER');

INSERT INTO USER_PROFILE(type)
VALUES ('ADMIN');

INSERT INTO USER_PROFILE(type)
VALUES ('DBA');

/* Populate one Admin User. We need only one user to demonstrate this example. You can add more as done in previous posts*/
INSERT INTO APP_USER(sso_id, password, first_name, last_name, email, state)
VALUES ('sam','abc125', 'Sam','Smith','[email protected]', 'Active');

/* Populate JOIN Table */
INSERT INTO APP_USER_USER_PROFILE (user_id, user_profile_id)
SELECT user.id, profile.id FROM app_user user, user_profile profile
where user.sso_id='sam' and profile.type='ADMIN';

安全部分

第4步：添加 Spring Security 配置類

package com.yiibai.springsecurity.configuration;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.authentication.rememberme.JdbcTokenRepositoryImpl;
import org.springframework.security.web.authentication.rememberme.PersistentTokenRepository;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

@Autowired
@Qualifier("customUserDetailsService")
UserDetailsService userDetailsService;

@Autowired
DataSource dataSource;

@Autowired
public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(userDetailsService);
}

@Override
protected void configure(HttpSecurity http) throws Exception {
  http.authorizeRequests()
      .antMatchers("/", "/home").permitAll()
      .antMatchers("/admin/\*\*").access("hasRole('ADMIN')")
      .antMatchers("/db/\*\*").access("hasRole('ADMIN') and hasRole('DBA')")
      .and().formLogin().loginPage("/login")
      .usernameParameter("ssoId").passwordParameter("password")
      .and().rememberMe().rememberMeParameter("remember-me").tokenRepository(persistentTokenRepository()).tokenValiditySeconds(86400)
      .and().csrf()
      .and().exceptionHandling().accessDeniedPage("/Access\_Denied");

}

@Bean
public PersistentTokenRepository persistentTokenRepository() {
    JdbcTokenRepositoryImpl tokenRepositoryImpl = new JdbcTokenRepositoryImpl();
    tokenRepositoryImpl.setDataSource(dataSource);
    return tokenRepositoryImpl;
}

}

第5步：使用war註冊springSecurityFilter

下面指定的初始化類註冊 springSecurityFilter 與應用程序 war [步驟3中創建]。

package com.yiibai.springsecurity.configuration;

import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;

public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {

}

以上配置以XML配置格式爲：

springSecurityFilterChain org.springframework.web.filter.DelegatingFilterProxy springSecurityFilterChain /\*

第6步：定義UserDetailsService實現

這項服務是負責提供身份驗證細節和驗證管理。

package com.yiibai.springsecurity.service;

import java.util.ArrayList;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.yiibai.springsecurity.model.User;
import com.yiibai.springsecurity.model.UserProfile;

@Service("customUserDetailsService")
public class CustomUserDetailsService implements UserDetailsService{

@Autowired
private UserService userService;

@Transactional(readOnly=true)
public UserDetails loadUserByUsername(String ssoId)
        throws UsernameNotFoundException {
    User user = userService.findBySso(ssoId);
    System.out.println("User : "+user);
    if(user==null){
        System.out.println("User not found");
        throw new UsernameNotFoundException("Username not found");
    }
        return new org.springframework.security.core.userdetails.User(user.getSsoId(), user.getPassword(), 
             user.getState().equals("Active"), true, true, true, getGrantedAuthorities(user));
}


private List<GrantedAuthority> getGrantedAuthorities(User user){
    List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();

    for(UserProfile userProfile : user.getUserProfiles()){
        System.out.println("UserProfile : "+userProfile);
        authorities.add(new SimpleGrantedAuthority("ROLE\_"+userProfile.getType()));
    }
    System.out.print("authorities :"+authorities);
    return authorities;
}

}

SpringMVC部分

第7步: 添加控制器

package com.yiibai.springsecurity.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.web.authentication.logout.SecurityContextLogoutHandler;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class HelloWorldController {

@RequestMapping(value = { "/", "/home" }, method = RequestMethod.GET)
public String homePage(ModelMap model) {
    model.addAttribute("greeting", "Hi, Welcome to mysite");
    return "welcome";
}

@RequestMapping(value = "/admin", method = RequestMethod.GET)
public String adminPage(ModelMap model) {
    model.addAttribute("user", getPrincipal());
    return "admin";
}

@RequestMapping(value = "/db", method = RequestMethod.GET)
public String dbaPage(ModelMap model) {
    model.addAttribute("user", getPrincipal());
    return "dba";
}

@RequestMapping(value = "/Access\_Denied", method = RequestMethod.GET)
public String accessDeniedPage(ModelMap model) {
    model.addAttribute("user", getPrincipal());
    return "accessDenied";
}

@RequestMapping(value = "/login", method = RequestMethod.GET)
public String loginPage() {
    return "login";
}

@RequestMapping(value="/logout", method = RequestMethod.GET)
public String logoutPage (HttpServletRequest request, HttpServletResponse response) {
    Authentication auth = SecurityContextHolder.getContext().getAuthentication();
    if (auth != null){    
        new SecurityContextLogoutHandler().logout(request, response, auth);
    }
    return "redirect:/login?logout";
}

private String getPrincipal(){
    String userName = null;
    Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();

    if (principal instanceof UserDetails) {
        userName = ((UserDetails)principal).getUsername();
    } else {
        userName = principal.toString();
    }
    return userName;
}

}

第8步: 添加 SpringMVC 配置類

package com.yiibai.springsecurity.configuration;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.yiibai.springsecurity")
public class HelloWorldConfiguration extends WebMvcConfigurerAdapter {

@Bean(name="HelloWorld")
public ViewResolver viewResolver() {
    InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
    viewResolver.setViewClass(JstlView.class);
    viewResolver.setPrefix("/WEB-INF/views/");
    viewResolver.setSuffix(".jsp");

    return viewResolver;
}

/\*
 \* Configure ResourceHandlers to serve static resources like CSS/ Javascript etc...
 \*
 \*/
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/static/\*\*").addResourceLocations("/static/");
}

}

第9步: 添加初始化類

package com.yiibai.springsecurity.configuration;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class SpringMvcInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

@Override
protected Class<?>\[\] getRootConfigClasses() {
    return new Class\[\] { HelloWorldConfiguration.class };
}

@Override
protected Class<?>\[\] getServletConfigClasses() {
    return null;
}

@Override
protected String\[\] getServletMappings() {
    return new String\[\] { "/" };
}

}

Hibernate配置部分

第10步: 創建Hibernate配置

Hibernate配置類包含數據源層，SessionFactory和事務管理的@Bean方法。數據源屬性是取自 application.properties 文件，包含MySQL數據庫詳細連接信息。

package com.yiibai.springsecurity.configuration;

import java.util.Properties;

import javax.sql.DataSource;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate4.HibernateTransactionManager;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@Configuration
@EnableTransactionManagement
@ComponentScan({ "com.yiibai.springsecurity.configuration" })
@PropertySource(value = { "classpath:application.properties" })
public class HibernateConfiguration {

@Autowired
private Environment environment;

@Bean
public LocalSessionFactoryBean sessionFactory() {
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
    sessionFactory.setDataSource(dataSource());
    sessionFactory.setPackagesToScan(new String\[\] { "com.yiibai.springsecurity.model" });
    sessionFactory.setHibernateProperties(hibernateProperties());
    return sessionFactory;
 }

@Bean
public DataSource dataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
    dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
    dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
    dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
    return dataSource;
}

private Properties hibernateProperties() {
    Properties properties = new Properties();
    properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
    properties.put("hibernate.show\_sql", environment.getRequiredProperty("hibernate.show\_sql"));
    properties.put("hibernate.format\_sql", environment.getRequiredProperty("hibernate.format\_sql"));
    return properties;        
}

@Bean
@Autowired
public HibernateTransactionManager transactionManager(SessionFactory s) {
   HibernateTransactionManager txManager = new HibernateTransactionManager();
   txManager.setSessionFactory(s);
   return txManager;
}

}

application.properties

jdbc.driverClassName = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/yiibai
jdbc.username = myuser
jdbc.password = mypassword
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = true

DAO, Model & Service服務

第11步: 創建模型類

用戶可以有多個角色[DBA，ADMIN，USER]。而角色可以被分配給一個以上的用戶。因此，有一個用戶和用戶配置[角色]之間存在多對多的關係。我們保持這種關係單向[用戶到用戶配置]，因爲我們只是在查找對於給用戶的角色。我們將使用使用連接表來實現多一對多關聯。

package com.yiibai.springsecurity.model;

import java.util.HashSet;
import java.util.Set;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.Table;

@Entity
@Table(name="APP_USER")
public class User {

@Id @GeneratedValue(strategy=GenerationType.IDENTITY)
private int id;

@Column(name="SSO\_ID", unique=true, nullable=false)
private String ssoId;

@Column(name="PASSWORD", nullable=false)
private String password;

@Column(name="FIRST\_NAME", nullable=false)
private String firstName;

@Column(name="LAST\_NAME", nullable=false)
private String lastName;

@Column(name="EMAIL", nullable=false)
private String email;

@Column(name="STATE", nullable=false)
private String state=State.ACTIVE.getState();

@ManyToMany(fetch = FetchType.EAGER)
@JoinTable(name = "APP\_USER\_USER\_PROFILE", 
         joinColumns = { @JoinColumn(name = "USER\_ID") }, 
         inverseJoinColumns = { @JoinColumn(name = "USER\_PROFILE\_ID") })
private Set<UserProfile> userProfiles = new HashSet<UserProfile>();

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getSsoId() {
    return ssoId;
}

public void setSsoId(String ssoId) {
    this.ssoId = ssoId;
}

public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

public String getFirstName() {
    return firstName;
}

public void setFirstName(String firstName) {
    this.firstName = firstName;
}

public String getLastName() {
    return lastName;
}

public void setLastName(String lastName) {
    this.lastName = lastName;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public String getState() {
    return state;
}

public void setState(String state) {
    this.state = state;
}

public Set<UserProfile> getUserProfiles() {
    return userProfiles;
}

public void setUserProfiles(Set<UserProfile> userProfiles) {
    this.userProfiles = userProfiles;

第12步: 創建 Dao 層

package com.yiibai.springsecurity.dao;

import java.io.Serializable;

import java.lang.reflect.ParameterizedType;

import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;

public abstract class AbstractDao<PK extends Serializable, T> {

private final Class<T> persistentClass;

@SuppressWarnings("unchecked")
public AbstractDao(){
    this.persistentClass =(Class<T>) ((ParameterizedType) this.getClass().getGenericSuperclass()).getActualTypeArguments()\[1\];
}

@Autowired
private SessionFactory sessionFactory;

protected Session getSession(){
    return sessionFactory.getCurrentSession();
}

@SuppressWarnings("unchecked")
public T getByKey(PK key) {
    return (T) getSession().get(persistentClass, key);
}

public void persist(T entity) {
    getSession().persist(entity);
}

public void delete(T entity) {
    getSession().delete(entity);
}

protected Criteria createEntityCriteria(){
    return getSession().createCriteria(persistentClass);
}

}

package com.yiibai.springsecurity.dao;

import com.yiibai.springsecurity.model.User;

public interface UserDao {

User findById(int id);

User findBySSO(String sso);

}

package com.yiibai.springsecurity.dao;

import org.hibernate.Criteria;
import org.hibernate.criterion.Restrictions;
import org.springframework.stereotype.Repository;

import com.yiibai.springsecurity.model.User;

@Repository("userDao")
public class UserDaoImpl extends AbstractDao<Integer, User> implements UserDao {

public User findById(int id) {
    return getByKey(id);
}

public User findBySSO(String sso) {
    Criteria crit = createEntityCriteria();
    crit.add(Restrictions.eq("ssoId", sso));
    return (User) crit.uniqueResult();
}

}

第13步: 創建Service層

package com.yiibai.springsecurity.service;

import com.yiibai.springsecurity.model.User;

public interface UserService {

User findById(int id);

User findBySso(String sso);

}

package com.yiibai.springsecurity.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.yiibai.springsecurity.dao.UserDao;
import com.yiibai.springsecurity.model.User;

@Service("userService")
@Transactional
public class UserServiceImpl implements UserService{

@Autowired
private UserDao dao;

public User findById(int id) {
    return dao.findById(id);
}

public User findBySso(String sso) {
    return dao.findBySSO(sso);
}

}

視圖部分

第14步：添加視圖

login.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<body>
    <div id="mainWrapper">
        <div class="login-container">
            <div class="login-card">
                <div class="login-form">
                    <c:url var="loginUrl" value="/login" />
                    <form action="${loginUrl}" method="post" class="form-horizontal">
                        <c:if test="${param.error != null}">
                            <div class="alert alert-danger">
                                <p>Invalid username and password.</p>
                            </div>
                        </c:if>
                        <c:if test="${param.logout != null}">
                            <div class="alert alert-success">
                                <p>You have been logged out successfully.</p>
                            </div>
                        </c:if>
                        <div class="input-group input-sm">
                            <label class="input-group-addon" for="username"><i class="fa fa-user"></i></label>
                            <input type="text" class="form-control" id="username" name="ssoId" placeholder="Enter Username" required>
                        </div>
                        <div class="input-group input-sm">
                            <label class="input-group-addon" for="password"><i class="fa fa-lock"></i></label> 
                            <input type="password" class="form-control" id="password" name="password" placeholder="Enter Password" required>
                        </div>
                        <div class="input-group input-sm">
                          <div class="checkbox">
                            <label><input type="checkbox" id="rememberme" name="remember-me"> Remember Me</label>  
                          </div>
                        </div>
                        <input type="hidden" name="${\_csrf.parameterName}"
                            value="${\_csrf.token}" />

                        <div class="form-actions">
                            <input type="submit"
                                class="btn btn-block btn-primary btn-default" value="Log in">
                        </div>
                    </form>
                </div>
            </div>
        </div>
    </div>

</body>

正如你所看到的，CSRF參數需要在JSP中的EL表達式訪問，所以還需要通過添將以下的代碼添加JSP的頂部來強行執行EL表達式解析編譯：

<%@ page isELIgnored="false"%>

admin.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags"%>

Dear ${user}, Welcome to Admin Page.

<sec:authorize access="isFullyAuthenticated()">
    <label><a href="#">Create New User</a> | <a href="#">View existing Users</a></label>
</sec:authorize>
<sec:authorize access="isRememberMe()">
    <label><a href="#">View existing Users</a></label>
</sec:authorize>

<a href="<c:url value="/logout" />">Logout</a>

以下提到的視圖在這個帖子中不需要，只是在這裏提及，作爲一個完整的補充。

welcome.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

dba.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

Dear ${user}, Welcome to DBA Page. ">Logout

accessDenied.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

Dear ${user}, You are not authorized to access this page ">Logout

第16步 - 構建和部署應用程序

現在構造 war(通過 eclipse/m2eclipse)或通過Maven的命令行(mvn clean install)。部署WAR文件到Servlet3.0容器。由於這裏我使用的是在 eclipse 中配置 Tomcat，可以直接發佈到 Tomcat 服務容器中。如果不知道怎麼使用，可以參考：http://www.yiibai.com/maven/create-a-maven-web-project-with-eclipse.html

運行應用程序

打開瀏覽器並訪問 -  http://localhost:8080/SpringSecurityRememberMeAnnotation/admin

系統將提示您登錄，如下圖中所示 - 

使用"記住我" 驗證登錄(使用用戶：kenny/123456)，您將獲得管理員視圖，如下所示 - 

驗證查看 Cookies。打開谷歌瀏覽器設置/顯示高級設置/內容設置/所有Cookie和網站數據顯示本地主機。你會發現有兩個 cookies ，一個用於當前會話[JSESSIONID]，一個用於"記住我"的身份驗證。

點擊"記住我"(remember-me)，查看cookie詳細信息。你可以看到 cookie 的有效期是一天(如在安全配置設置)。

現在查看 persistent_logins 表中數據。應該有當前用戶的 Cookies 記錄信息。

現在退出登錄，如下圖中所示  - 

現在再試嘗試打開：http://localhost:8080/SpringSecurityRememberMeAnnotation/admin，應該直接登錄，而不再需要使用輸入用戶名和密碼登錄。

還可以看到 「Create New User」 選項不可用，這是因爲一個是僅當用戶(使用登錄名/密碼，例如)有權限的認證才能使用此功能，現在從Chrome中刪除 "記住我" 的cookie(如前所示)，並再次嘗試訪問： http://localhost:8080/SpringSecurityRememberMeAnnotation/admin，程序應該提示您登錄。

就這麼多， 下一篇文章我們將來學習使用 Spring Security 的 @PreAuthorize，@PostAuthorize，@Secured和Spring EL表達式的方法級的安全控制。
