Spring在bean配置文件中定義電子郵件模板

在上一篇Spring電子郵件教程，硬編碼的所有電子郵件屬性和消息的方法體中的內容，這是不實際的，應予以避免。應該考慮在Spring bean 配置文件中定義電子郵件模板。

1.Spring的郵件發件人

Java類使用 Spring的MailSender接口發送電子郵件，並使用 String.Format 傳遞變量bean配置文件替換電子郵件中的 '%s'。

File : MailMail.java

package com.yiibai.common;

import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;

public class MailMail
{
private MailSender mailSender;
private SimpleMailMessage simpleMailMessage;

public void setSimpleMailMessage(SimpleMailMessage simpleMailMessage) {
    this.simpleMailMessage = simpleMailMessage;
}

public void setMailSender(MailSender mailSender) {
    this.mailSender = mailSender;
}

public void sendMail(String dear, String content) {

   SimpleMailMessage message = new SimpleMailMessage(simpleMailMessage);

   message.setText(String.format(
        simpleMailMessage.getText(), dear, content));

   mailSender.send(message);

}    

}

2. Bean的配置文件

定義電子郵件模板「customeMailMessage' 和郵件發件人信息的bean配置文件。

File : Spring-Mail.xml

<property name="javaMailProperties">
     <props>
           <prop key="mail.smtp.auth">true</prop>
           <prop key="mail.smtp.starttls.enable">true</prop>
            </props>
</property>

<property name="from" value="[email protected]" />
<property name="to" value="[email protected]" />
<property name="subject" value="Testing Subject" />
<property name="text">
   <value>
    <!\[CDATA\[
        Dear %s,
        Mail Content : %s
    \]\]>
   </value>
    </property>

4. 運行它

package com.yiibai.common;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

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

    MailMail mm = (MailMail) context.getBean("mailMail");
    mm.sendMail("Yiibai", "This is text content");

}

}

輸出

Dear Yiibai,
Mail Content : This is text content
