新项目报：Causedby:javax.net.ssl.SSLHandshakeException:

新项目启动&＃xff0c;报错&＃xff0c;错误见下面三个图片

com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

解决办法

在项目配置文件yml的mysql的url 最后添加 &useSSL&＃61;false

jdbc:mysql://192.168.1.101:3306/xxx_admin?useUnicode&＃61;true&characterEncoding&＃61;UTF-8&serverTimezone&＃61;Asia/Shanghai&useSSL&＃61;false


添加后就不再报错。

原因&＃xff1a;当前jdk版本 jdk1.8.0_301
&＃xff1a;“useSSL&＃61;true 是进行安全验证,一般通过证书或者令牌,useSSL&＃61;false就是通过账号密码进行连接,通常使用useSSL&＃61;false。
