过了一段时间之后后台打印出了连接邮箱服务器超时的日志。

原因是Couldnt connect to host, port: smtp.163.com, 25
但是通过终端连接smtp.163.com是成功的
ping smtp.163.com 但是尝试访问25端口却无响应
telnet smtp.163.com 25 于是在网上查找了一些解决方案最后采用了通过ssl连接的方式在原来的邮件设置中加入以下设置
spring:mail:port: 25host: smtp.163.comdefault-encoding: UTF-8username: xxxxx163.compassword: xxxxxxxxxxxxx# 以下是新增的设置properties:mail:debug: truesmtp:auth: truessl:trust: smtp.163.comstarttls:enable: truerequired: truesocketFactory:port: 465class: javax.net.ssl.SSLSocketFactory
最后重启服务登陆的时候成功发出了邮件。
