Mybatis-Caused by: java.security.cert.CertPathValidatorException: Path does not chain with any of th

Posted 2021-09-21 Zhang Daopin

    一开始没有配置SSL的选项，日志中有个WARN警告：

Wed Aug 04 10:10:55 CST 2021 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.

    按照提示添加上了SSL的配置useSSL=true，啪~来了一堆没有见过的异常。。。

    其实非常简单，只需要将useSSL=true  修改为：useSSL=false即可
