用spring做一个javaMail功能的例子
前言：项目中要做一个发送邮件的功能，在网上搜了一些代码，说的都不是很完善。自己就整理了一个可以运行的项目。需要注意的地方是：如果发送人的邮箱是qq邮箱，那么需要在 设置->账户里面把√打上。spring里面的
<property name="host">
??? <value>smtp.126.com</value>
?? </property>
要配置成smtp.qq.com
126邮箱同理。
步骤如下：
用spring做一个javaMail功能。
1、先建一个项目。java项目和web项目均可。
2、需要引入的jar包有：mail.jar，activation.jar（我用的是maven搭建的项目，在pom.xml中依赖了那两个jar包）
3、在MyEclipse的项目里面加入spring的jar包
4、在项目中的applicationContext-init.xml（名字可以任意改）文件中加入如下代码：
<?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.xsd">
<bean id="mailSender" <property name="host">
??? <value>smtp.126.com</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>xiaojunwei_1987</value>
?? </property>
?? <property name="password">
<!--这里的是配置自己邮箱的密码，这里我输入的是假的，以*代替了，呵呵要不你们就知道我的邮箱密码了-->
??? <value>********</value>
?? </property>
</bean>
</beans>
java 代码：我自己加的注释，不一定准确哦。
