解决jdk1.8中发送邮件失败（handshake_failure）问题

暑假在家做一个类似知乎的问答型网站（代码可见：Github/wenda 喜欢的可以给个star或者自己fork然后修改，目前功能还未很完善），其中有一个站内邮件通知系统（这里简单的讲一个例子：如果用户登录的时候出现异常，那么就会通过邮件发送通知用户）。然而却碰到一个问题。问题错误信息如下：

发送邮件失败Mail server connection failed; nested exception is javax.mail.MessagingException: Could not connect to SMTP host: smtp.qq.com, port: 465;
nested exception is: javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure. Failed messages: javax.mail. MessagingException: Could not connect to SMTP host: smtp.qq.com, port: 465;
nested exception is: javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

自己在将错误信息代码google了一下，找了很久发现很多解决方案，包括stackoverflow上的一些解决方案，但还是没用。然后呢用百度试了下，结果在第一条是开源中国的一篇博客:javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure。
百度出来的结果

点进去是这样的：（如下图）
开源中国

正确解决方式

结果就是：这个问题是jdk导致的，jdk1.8里面有一个jce的包，安全性机制导致的访问https会报错，官网上有替代的jar包，如果替换掉就可以了。问题的解决方法还可以就是在整个项目中把你的jdk换成是1.7去，同样也可以解决这个我问题。

这两个jar包的下载地址：http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

包下载

然后下载之后，把这个压缩文件解压，得到两个jar包去覆盖jdk安装目录下的jre\lib\security\下相同的jar包就能解决java8的邮件发送问题。

接着用QQ邮箱我亲测有用，但是要注意一点就是：开启SMTP服务后要记得将你的16位授权码作为你的qq邮箱登录密码。

MailSender.java中mailSender.setPassword(“16位授权码”);

mailSender.setHost(“smtp.qq.com”);
mailSender.setPort(465);

开启服务注意的地方

16位授权码

你好$username，你的登陆有问题!

一切都好了，运行。

登录。

发送邮件过来了。

邮件发过来了

总结来说：这个错误就是jdk1.8中的一个jce的包，安全性机制导致访问https会报错。
