spring发送邮件demo

1.环境准备，所需jar包

2。在src目录下建立一个maisender.properties文件，里面写一些常用的配置

   如果邮箱服务器采用QQ邮箱则下面书写

mail.host=smtp.qq.com
mail.username=XXXXXXXXXX@qq.com
mail.password=XXXXXXXX

如果126邮箱服务器

mail.host=smtp.126.com
mail.username=xxxxxxxx@qq.com
mail.password=xxxxxxxx

3.在src目录下建立一个applicationContext.xml文件，这个是使用spring框架的配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/beans   
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd   
    http://www.springframework.org/schema/tx   
    http://www.springframework.org/schema/tx/spring-tx-3.0.xsd  
    http://www.springframework.org/schema/context  
    http://www.springframework.org/schema/context/spring-context-3.0.xsd  
    http://www.springframework.org/schema/mvc  
    http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
    
    <context:component-scan base-package="com.*"></context:component-scan>
    
    <mvc:annotation-driven/>
    
    <bean id="propertyConfigurer"
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    	<property name="fileEncoding" value="utf-8" />
    	<property name="locations">
    	 <list>
    	  <value>mailsender.properties</value>
    	 </list>
    	</property>
    </bean>
    
    <bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
     <property name="host">
      <value>${mail.host}</value>
     </property>
     <property name="javaMailProperties">
            <props>
              <prop key="mail.smtp.auth">true</prop>
              <prop key="mail.smtp.timeout">25000</prop>
            </props>
        </property>	
     <property name="username">
      <value>${mail.username}</value>
     </property>
     <property name="password">
      <value>${mail.password}</value>
     </property>
    </bean>
    
    </beans>

4.在src目录下新建java文件

package com.email;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;

public class SpringSimpleEmail {
	public static void main(String[] args) {
		try {
		ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
		JavaMailSender sender = (JavaMailSender)ctx.getBean("javaMailSender");
		MimeMessage msg = sender.createMimeMessage();
			MimeMessageHelper helper = new MimeMessageHelper(msg,true,"utf-8");
			helper.setFrom("[email protected]");
			helper.setTo("[email protected]");
			helper.setText("tets this is a spring mvc email");
			helper.setSubject("xxxxxxx");
			sender.send(msg);
			System.out.println("email send ok");
			
		} catch (MessagingException e) {
			System.out.println("send fail");
			e.printStackTrace();
		}
		
	}
}

5.点击运行便可收到邮件。。笔者亲自测试的。
