Caused by: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cip

1. 问题场景

在spring boot启动时链接本地数据库报错 错误信息如下

2. 原因

默认会使用https的协议进行连接数据库 会使用ssl 认证 如果链接的地址不支持https连接就会报这个错误

3. 解决

在mysql的连接中关闭使用ssl认证 即可 useSSL=false
示例配置如下

 spring.datasouce.url=jdbc:mysql://localhost:3306/test?useSSL=false&useUnicode=true&characterEncoding=UTF-8&rewriteBatchedStatements=true&serverTimezone=Asia/Shanghai
