spring框架是由于软件开发的复杂性而创建的。spring使用的是基本的javabean来完成以前只可能由ejb完成的事情。然而，spring的用途不仅仅限于服务器端的开发。从简单性、可测试性和松耦合性角度而言，绝大部分java应用都可以从spring中受益。
首先进入自己的qq邮箱，在设置中修改账户信息
然后来至底部
点击开启，再用手机发送对应信息到指定号码，然后点击我已发送
获取授权码
注意提示：
到这里，相信你已经开通了smtp服务，这样就可以在java code发送邮件了
接下来的是spring 中使用邮件服务
首先是配置信息使用的是587端口，刚开始用465端口我纠结了好久(使用465端口的错误详情)，用不了，你可以尝试，默认的25端口应该也是不适合的

温馨提示：
<img src='cid:javaxmail.png'>
这是内嵌图片的方式 javaxmail.png 要和 messagehelper.addinline(file.getfilename(), file); 这里的 file.getfilename() 相一致就可以
现在只差一步了，那就是ctrl + f11，有不当之处敬请提出，共同进步
