数据库连接出现版本过高异常lower_case_table_names

在Java连接数据库时，使用MySQL的驱动，出现了Unknown
system variable 'lower_case_table_names'异常，而且有警告：
WARN: Establishing SSL connection without server's identity verification is not recommended. According tomysql 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：

使用驱动mysql-connector-java-5.0.8-bin.jar版本，就会避免这种异常出现。
使用mysql-connector-java-5.1.38-bin.jar版本时，会出现上述异常与警告。
使用低版本的驱动jar可以避免这种问题。
