把你这个配置文件里面的email_template.properties参数项改一下试试···

提示的是注册时连接邮件认证失败，是物理连接问题。

追问

可以说具体一点吗？工程里面有一个邮件模板email_template.properties,不明白properties的用法。

追答

这个就需要慢慢调试了，可能性太多，不是在这里能解决的。
properties是配置文件，看是不是有些服务器地址什么的设置需要调整。

Answer 3

smtp.163.com 在email.properties配置文件中 的password是在163邮箱开通smtp服务中的授权码而不是邮箱密码

Answer 4

服务器出错了，看一下servers

Answer 5
