jaxax.mail提供了原生的邮件发送和接受api，spring.mail在此基础上提供了进一层的封装，使用起来更方便。它屏蔽了一些底层的实现和细节，使我们可以用起来可以更方便。
环境：
javamail 1.4.4
spring 3.2.3RELEASE
maven
首先，在pom.xml添加以下依赖：spring.mail包被整合在spriing-context-support中。
<!-- javamail API -->
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4.4</version>
</dependency>
<!-- spring framework -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>3.2.3.RELEASE</version>
</dependency>
在resrouces下面添加spring-mail.xml

config.properties添加smtp属性
## mail
##smtp服务器地址
mail.smtp.host=smtp.qq.com
##smtp服务器端口
mail.smtp.port=25
##帐号
mail.smtp.username=21936354
##发件人
mail.smtp.from=21936354@qq.com
##密码
mail.smtp.password=*********
##是否需要认证
mail.smtp.auth=true
新建文件MailService.java.MailService就是直接最顶层的api，接收附件文件列表，标题，内容以及收件人列表。
