首先，请参考这一片文章，配置好James邮件服务器

发送MIME消息的一个主要缺点是你不能使用SimpleMailMessage来做外部配置，因为JavaMailSenderImp的MIME相关方法不能用在SimpleMailMessage上，由于这个原因，通常最好做法就是创建一个用来封装MIME的消息的类，以便Spring能在外部进行配置，我们首先定义一个允许外部配置消息的通用基类，如下

package ch15.SimpleMimeMail;

import org.springframework.mail.javamail.JavaMailSenderImpl;

public abstract class AbstractMessageSender {

protected String to;

protected String from;

protected String subject;

protected String text;

protected JavaMailSenderImpl sender;

public String getTo() {

return to;

}

public void setTo(String to) {

this.to = to;

}

public String getFrom() {

return from;

}

public void setFrom(String from) {

this.from = from;

}

public String getSubject() {

return subject;

}

public void setSubject(String subject) {

this.subject = subject;

}

public String getText() {

return text;

}

public void setText(String text) {

this.text = text;

}

public JavaMailSenderImpl getSender() {

return sender;

}

public void setSender(JavaMailSenderImpl sender) {

this.sender = sender;

}

邮件发送类(AbstractMessageSender 的实现类)

一个HTML消息的创建与纯文本电子邮件差不多，但你必须指定你所创建的消息的MIME类型是text/html,尽管你不能使用SimpleMailMessage,但Spring提供了MimiMessageHelper类，他允许使用与SimpleMailMessage相似的方式处理MIME消息，避免了一些JavaMail

package ch15.SimpleMimeMail;

import javax.mail.MessagingException;

import javax.mail.internet.MimeMessage;

import org.springframework.mail.javamail.MimeMessageHelper;

public class SimpleHTMLMessageSender extends AbstractMessageSender {

private MimeMessageHelper helper;

private MimeMessage msg;

public void sendMessage(){

msg=sender.createMimeMessage();

helper=new MimeMessageHelper(msg);

try {

helper.setTo(to);

helper.setFrom(from);

helper.setSubject(subject);

helper.setText(text,true);//true表示text/html格式邮件

}catch (MessagingException e) {

System.out.println(e.getMessage());

}

sender.send(msg);

}

这里需要啰嗦的是MimeMessage实例是由JavaMailSenderImpl创建的，MimiMessageHelper用来设置一个MimiMEssage实例，其setText方法，接受两个参数，一个是html页面语言，一个是true,表明这个消息是一个html消息

配置文件：

<?xml version="1.0" encoding="UTF-8"?>

<beans

xmlns="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-2.0.xsd">

测试代码：

package ch15.SimpleMimeMail;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import org.springframework.mail.SimpleMailMessage;

import org.springframework.mail.javamail.JavaMailSenderImpl;

public class SimpleMimeTest {

public static void main(String[] args) throws Exception {

ApplicationContext context=new ClassPathXmlApplicationContext("ch15/SimpleMimeMail/applicationContext.xml");

SimpleHTMLMessageSender mailSender=(SimpleHTMLMessageSender)context.getBean("messageSender");

for (int i = 0; i < 10; i++) {

mailSender.sendMessage();

System.out.println("成功");

Thread.sleep(2000); //发送后延时2秒钟

}
