java-Java的框架SSH整合的项目，项目启动时总是会报一个莫名其妙的错误？
java框架mysqljava ssh数据库连接池
Unable to load configuration. - [unknown location]

Caused by: java.net.ConnectException: Connection timed out: connect
个人分析应该不是jar包冲突的问题，因为项目以前是可以正常运行的，以前出过一次这样的问题，但是放了两天之后再运行又可以正常运行了。。。。现在又出现了这样的问题，百度上有人说是因为查询次数太多导致无法查询，但是如代码所示，无论是在junit测试类中还是在spring容器刚刚初始化完成利用监听器立即查询所有权限的功能，均可以正常访问到数据库，所以应该也不是c3p0数据库连接池的原因，整的我现在也不知道到底是什么问题。。求指教。
