maven之javamail操作qq的smtp与imap

参考：

java mail 官网 https://java.net/projects/javamail/pages/Home#Samples

  maven 添加javamail支持               http://blog.csdn.net/dai_richard/article/details/7070713

 qq的imap需要使用ssl 的993端口进行通信  http://blog.csdn.net/superstorm5/article/details/2157022

书籍-- java 网络编程精解(孙卫琴)

先看一些理论的东西

qq的邮箱账号 先要开通imap/smtp  在邮箱的  设置--账号 里面 如下

最后再来个测试代码  代码上都加了注释 不废话
