当使用spring boot的jpa连接高版本的mysql时会有如下报错
Mon Jul 16 15:58:31 CST 2018 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.
这时需要将application.properties文件的配置
spring.datasource.url=jdbc:mysql://localhost:3306/jpa?useUnicode=true&characterEncoding=utf-8
改为
spring.datasource.url=jdbc:mysql://localhost:3306/jpa?useUnicode=true&characterEncoding=utf-8&useSSL=true
增加&useSSL=true即可
