Spring Boot Mail QQ企業(yè)郵箱無法連接解決方案

更新時間：2020年09月21日 11:11:46 作者：手撕高達的村長

這篇文章主要介紹了Spring Boot Mail QQ企業(yè)郵箱無法連接解決方案,文中通過示例代碼介紹的非常詳細，對大家的學習或者工作具有一定的參考學習價值,需要的朋友可以參考下

這里記錄一下QQ企業(yè)郵箱發(fā)郵件問題,因為之前遇到過一種情況是本地測試沒問題,結(jié)果線上出現(xiàn)問題

Couldn't connect to host, port: smtp.qq.com, 25; timeout -1

要使用企業(yè)郵箱生成的授權密碼.

這里只要是因為QQ郵箱默認端口是465,需要修改為SSL配置
