JDBC连接数据库时发出警告的问题及解决办法

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.

解决办法：在数据库名后加上 ?useUnicode=true&useSSL=true
