c3p0的出现，是为了大大提高应用程序和数据库之间访问效率的。

　　它的特性：

  1. 编码的简单易用
  2. 连接的复用
  3. 连接的管理

今天在配置C3p0的时候出现了这个warn   原因是因为要验证SSL

Wed Sep 13 00:03:35 CST 2017 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.

从提示中可以看到需要将useSSL 设置为false  就可以解决这个问题

可以 看到在Url  之后 加入 useSSL = false  就没有这个warning  出现了
