J2EE 课程设计实训项目——《蓝梦网上商城》——应用Spring JavaMail 邮件抽象实现项目中的邮件自动发送功能1.1.1应用Spring JavaMail邮件抽象实现项目中的邮件自动发送功能1、Spring JavaMail概述E-mail是一个优秀的通知系统，也充当一个基本的工作流系统的角色。

Spring使发送邮件变得非常容易，它隐藏底层邮件系统的复杂性。

Spring邮件支持的主要接口叫做MailSender。

它还提供了一个SimpleMailMessage类来封装一条消息的公共属性(from, to, subject, message)。

如果我们想发送带附件的邮件，则可以用MimeMessagePreparator来创建和发送消息。

下面给出一个在本项目中的实现示例。

2、修改webShopUserInfoIoC.xml文件以添加与Spring邮件抽象实现相关的组件（1）定义一个org.springframework.mail.javamail.JavaMailSenderImpl组件对象<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"><property name="host" value=""/><property name="username" value="trainict"/><property name="password" value="6407"/></bean>（2）并将该组件对象注入到我们的Spring事件广播的响应的组件SpringActionEventResponse类中<bean id="springActionEventResponse" class="com.px1987.webshop.business.springevent.SpringActionEventResponse"> <property name="mailSender"><ref bean="mailSender"/></property></bean>（3）到目前为止的配置示例如下<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "/dtd/spring-beans-2.0.dtd"><beans><bean id="userInfoCRUDImple" class="erInfoCRUDImple" scope="prototype"> </bean><bean id="orderInfoCRUDImple" class="com.px1987.webshop.dao.crud.OrderInfoCRUDImple" scope="prototype"> </bean><bean id="goodsInfoCRUDImple" class="com.px1987.webshop.dao.crud.GoodsInfoCRUDImple" scope="prototype"> </bean><bean id="userInfoDAOServiceImple" class="erInfoDAOServiceImple" scope="prototype"> <property name="userInfoCRUDImple"><ref bean="userInfoCRUDImple"/></property><property name="orderInfoCRUDImple"><ref bean="orderInfoCRUDImple"/></property><property name="goodsInfoCRUDImple"><ref bean="goodsInfoCRUDImple"/></property></bean><bean id="orderInfoDAOServiceImple" class="com.px1987.webshop.service.OrderInfoDAOServiceImple" scope="prototype"> <property name="userInfoCRUDImple"><ref bean="userInfoCRUDImple"/></property><property name="orderInfoCRUDImple"><ref bean="orderInfoCRUDImple"/></property><property name="goodsInfoCRUDImple"><ref bean="goodsInfoCRUDImple"/></property></bean><bean id="goodsInfoDAOServiceImple" class="com.px1987.webshop.service.GoodsInfoDAOServiceImple" scope="prototype"> <property name="userInfoCRUDImple"><ref bean="userInfoCRUDImple"/></property><property name="orderInfoCRUDImple"><ref bean="orderInfoCRUDImple"/></property><property name="goodsInfoCRUDImple"><ref bean="goodsInfoCRUDImple"/></property></bean><bean id="userInfoManageImple" class="erInfoManageImple"scope="prototype"><property name="userInfoDAOServiceImple"><ref bean="userInfoDAOServiceImple"/></property><property name="springActionEventResponse"><ref bean="springActionEventResponse"/></property></bean><bean id="springActionEventResponse"class="com.px1987.webshop.business.springevent.SpringActionEventResponse"> <property name="mailSender"><ref bean="mailSender"/></property></bean><bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"><property name="host" value=""/><property name="username" value="trainict"/><property name="password" value="12345678"/></bean></beans>3、在我们的Spring事件广播的响应的组件SpringActionEventResponse类中增加一个名称为mailSender的JavaMailSenderImpl成员属性对象，并提供set方法import org.springframework.mail.javamail.JavaMailSender;…private JavaMailSender mailSender=null;public void setMailSender(JavaMailSender mailSender){this.mailSender = mailSender;}4、编程我们的邮件发送功能代码package com.px1987.webshop.business.springevent;import org.springframework.context.ApplicationListener;import org.springframework.context.ApplicationEvent;import org.springframework.mail.javamail.JavaMailSender;import org.springframework.mail.MailException;import org.springframework.mail.javamail.MimeMessagePreparator;import javax.mail.internet.MimeMessage;import javax.mail.MessagingException;import javax.mail.internet.InternetAddress;import javax.mail.Message;public class SpringActionEventResponse implements ApplicationListener { private JavaMailSender mailSender=null;public void setMailSender(JavaMailSender mailSender) {this.mailSender = mailSender;}String userMail=null;String userName=null;String userPassWord=null;public SpringActionEventResponse() {}public void onApplicationEvent(ApplicationEvent applicationEvent) {//识别事件源对象是否为指定的事件类型if (applicationEvent instanceof SpringActionEvent) {userMail=((SpringActionEvent)applicationEvent).getOneUserInfo().getUserMail();userName=((SpringActionEvent)applicationEvent).getOneUserInfo().getUserName();userPassWord=((SpringActionEvent)applicationEvent).getOneUserInfo().getUserPassWord();MimeMessagePreparator preparator = new MimeMessagePreparator() { public void prepare(MimeMessage mimeMessage) throws MessagingException{mimeMessage.setRecipient(Message.RecipientType.TO,new InternetAddress(userMail));mimeMessage.setFrom(new InternetAddress("trainict@"));mimeMessage.setText("您在本系统中的注册用户名称为："+userName+ "密码为："+userPassWord);}};try{mailSender.send(preparator);}catch (MailException ex) {System.err.println("邮件发送过程中出现了错误："+ex.getMessage());return;}System.out.println("我们已经将您的ID及密码等信息发送到您的邮箱"+userMail);}}}。
