前面一直用javamail来发送，对比spring会显得臃肿复杂，利用spring只需简单的配置就可以实现发邮件的功能。

首先必须导入所必须的包activation.jar，commons-logging.jar，mail.jar，spring.jar

新建一个applicationContext .xml

 

 

<?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:aop="http://www.springframework.org/schema/aop"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd      http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">  

  <bean id="mailSender"    class="org.springframework.mail.javamail.JavaMailSenderImpl">   <property name="host">  

  <value>127.0.0.1</value><!-- 本地服务器  如果是其他，请填如：smtp.sohu.com-->

   </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>postmaster@mai.com</value> <!-- 我这里用本地的邮箱名--> 

        </property>  

        <property name="password">  

            <value>123456</value>  

        </property>  

    </bean>  

</beans>

然后建立一个java文件

 

package org.fantlam.spring;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import org.springframework.mail.SimpleMailMessage;

import org.springframework.mail.javamail.JavaMailSender;

 

public class SpringMail1 {

public static void main(String args[]){

 ApplicationContext ctx =new ClassPathXmlApplicationContext("applicationContext.xml");   

  JavaMailSender sender = (JavaMailSender) ctx.getBean("mailSender");   

 SimpleMailMessage mail = new SimpleMailMessage();

//这里SimpleMailMessage只能用来发送text格式的邮件

  try {   

  mail.setTo("fantlam@163.com");//接收者   

  mail.setFrom("sohu@mai.com");//按前面讲的，可以随便起

  mail.setSubject("spring mail test!");//主题   

  mail.setText("springMail的简单发送测试");//邮件内容   

  sender.send(mail);   

 } catch (Exception e) {   

  e.printStackTrace();   

 }   

 

}

}

这代码本身是没错的，一开始用了网易的老邮箱发送，它老给我报错

org.springframework.mail.MailSendException; nested exception details (1) are:

Failed message 1: com.sun.mail.smtp.SMTPSendFailedException: 553 You are not authorized to send mail, authentication is required

 at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1388)

    at org.springframework.mail.javamail.JavaMailSenderImpl.send(JavaMailSenderImpl.java:277)

    at org.fantlam.spring.SpringMail1.main(SpringMail1.java:20)

 

然后我试了一个新邮箱，报错又不一样。

 

org.springframework.mail.MailAuthenticationException: Authentication failed; nested exception is javax.mail.AuthenticationFailedException

    at org.springframework.mail.javamail.JavaMailSenderImpl.doSend(JavaMailSenderImpl.java:395)

不过这并不是代码本身的错误，是邮箱验证那些东西，后来我用了本地的服务器就可以成功发送了，这就是用spring发送的简单邮件，不用解释什么，一看就明白了。
