Java连接数据库警告WARN: Establishing SSL connection without server's identity ......

今天搭了个框架，发现数据库发出了警告

Fri Mar 23 13:49:33 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.

解决方案：
只需要在数据库后增加一行配置：
spring.master.datasource1.url= jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf8&useSSL=true
