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.mysql
出现以上的问题的缘由是当前版本的MySQL要求使用SSL,作出以下修改便可:sql
将Mysql的url改成数据库
主协议:子协议://主机名:端口号/数据库名字+useSSL=falseapp
jdbc:mysql://localhost:3306/user?useSSL=false
