springboot You need either to explicitly disable SSL by setting useSSL=false

问题描述

Wed Mar 15 13:12:47 GMT+08:00 2023 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

解决方案：在数据库连接配置中加入参数 useSSL=false

url: jdbc:mysql://127.0.0.1:3306/jdbc?useSSL=false

或者可以配置相关的SSL证书文件路径 后面更新此方案
