SpringBoot連接Mysql數據庫警告：Establishing SSL connection without server's identity verification is not recommend
Java使用mysql-jdbc連接MySQL出現如下警告：
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.
原因是MySQL在高版本需要指明是否進行SSL連接。解決方案如下：
在mysql連接字符串url中加入ssl=true或者false即可，如下所示。
url=jdbc:mysql://127.0.0.1:3306/framework?characterEncoding=utf8&useSSL=true
