<project xmlns="http://maven.apache.org/POM/4.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>com.itzheng</groupId>
	<artifactId>JavaMailDemo</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<dependencies>
		<dependency>
			<groupId>javax.mail</groupId>
			<artifactId>mail</artifactId>
			<version>1.4.4</version>

Three, write and send Email class

Write spring configuration file
Create applicationContext_mail.xml file, after copy file header constraint, add the following code

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context"

	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="

	<bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl" >
		
		<!-- smtp:发送邮件的协议 -->

	</bean>
	
	<bean id="testSend" class="com.itzheng.demo.TestSend" >
		<property name="javaMailSender" ref="javaMailSender" ></property>
	</bean>
	

</beans>

Four, send email

package com.itzheng.demo;

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

public class TestJavaMail {
    
    
	
	@Test
	public void testMail() throws Exception{
    
    
		
		ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext-mail.xml");
		TestSend ts = (TestSend) ac.getBean("testSend");
		ts.sendMail();
