C3P0的这个问题一直没有解决，我最后使用了proxool，完美解决了此问题，所以在此推荐大家使用proxool，稳定运行3个月了，没有出现问题

Java连接数据库时常见的SQLException异常原因
CdiBug的博客
09-19 887
以下是一些常见的导致SQLException异常的原因，并提供相应的示例代码进行说明。本文讨论了一些导致SQLException异常的常见原因，包括无效的数据库连接URL、错误的数据库凭据和数据库连接超时。在上面的示例中，URL “jdbc:mysql://localhost:3306/mydatabase” 是无效的，可能是因为数据库名称错误或端口号不正确。在上面的示例中，将连接超时时间设置为1秒钟。在上面的示例中，提供的用户名和密码与数据库凭据不匹配，因此会抛出SQLException异常。
