本文介绍了解决c3p0连接MySQL时出现的SSL警告问题。针对MySQL5.5.45+版本默认开启SSL连接的要求，通过设置c3p0配置参数useSSL为false或true并提供信任证书来解决此警告。

c3p0显示警告Thu Sep 28 09:52:06 CST 2017 WARN: Establishing SSL connection without server's identityverification 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.

修改c3p0的配置信息：添加如下代码即可
