Spring SimpleJdbcTemplate batchUpdate()實例

在本教程中，我們將向你展示如何在了SimpleJdbcTemplate類使用batchUpdate()。詳細請參見 在SimpleJdbcTemplate 類的 batchUpdate()示例 。

//insert batch example
public void insertBatch(final List customers){
String sql = "INSERT INTO CUSTOMER " +
"(CUST_ID, NAME, AGE) VALUES (?, ?, ?)";

List<Object\[\]> parameters = new ArrayList<Object\[\]>();

for (Customer cust : customers) {
    parameters.add(new Object\[\] {cust.getCustId(), 
        cust.getName(), cust.getAge()}
    );
}
getSimpleJdbcTemplate().batchUpdate(sql, parameters);        

}

或者，你可以直接執行SQL。

//insert batch example with SQL
public void insertBatchSQL(final String sql){

getJdbcTemplate().batchUpdate(new String\[\]{sql});

}

Spring 的 bean 配置文件

<bean id="customerSimpleDAO" 
    class="com.yiibai.customer.dao.impl.SimpleJdbcCustomerDAO">

    <property name="dataSource" ref="dataSource" />
</bean>

<bean id="dataSource" 
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">

    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://localhost:3306/yiibai" />
    <property name="username" value="root" />
    <property name="password" value="" />
</bean>

執行它

package com.yiibai.common;

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

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.yiibai.customer.dao.CustomerDAO;
import com.yiibai.customer.model.Customer;

public class App
{
public static void main( String[] args )
{
ApplicationContext context =
new ClassPathXmlApplicationContext("Spring-Customer.xml");

    CustomerDAO customerSimpleDAO = 
                  (CustomerDAO) context.getBean("customerSimpleDAO");

    Customer customer1 = new Customer(1, "yiibai1",21);
    Customer customer3 = new Customer(2, "yiibai2",22);
    Customer customer2 = new Customer(3, "yiibai3",23);

    List<Customer>customers = new ArrayList<Customer>();
    customers.add(customer1);
    customers.add(customer2);
    customers.add(customer3);

    customerSimpleDAO.insertBatch(customers);

    String sql = "UPDATE CUSTOMER SET NAME ='BATCHUPDATE'";
    customerSimpleDAO.insertBatchSQL(sql);

}

}

在本例中，插入三個顧客的記錄，並批量更新所有客戶的名字。
