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
出現以上的問題的緣由是當前版本的MySQL要求使用SSL,作出以下修改便可:sql
將Mysql的url改成數據庫
主協議:子協議://主機名:端口號/數據庫名字+useSSL=falseapp
jdbc:mysql://localhost:3306/user?useSSL=false
