Springboot整合163邮箱部署项目时发送不了邮件的解决方案

部署到腾讯云服务器时项目报错

 

Caused by: com.sun.mail.util.MailConnectException: Couldn't connect to host, port: smtp.163.com, 25; timeout -1

解决方案

yml文件中加入

spring:
  mail:
    host: smtp.163.com
    password: KWDIFGYSZICNDWHB
    username: abu13141110@163.com
    default-encoding: UTF-8
    properties:
      mail:
        smtp:
          socketFactory:
            class: javax.net.ssl.SSLSocketFactory
          auth: true
        debug: true
    port: 465    # 25端口被服务器禁止了，这里要使用其他端口
