问题描述

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？

Unable to load configuration. - [unknown location]

Caused by: Unable to load configuration. - [unknown location]

Caused by: Unable to load jar:file:/D:/mars-workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/vvvvvvvvvvv/WEB-INF/lib/struts2-spring-plugin-2.3.15.3.jar!/struts-plugin.xml - [unknown location]

Caused by: Connection timed out: connect - [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。

解决方案二：

同样的问题，参见http://blog.csdn.net/chexitianxia/article/details/6746345

解决方案三：

比如数据连接池 有的 连接没有释放。

解决方案四：

首先，如果是启动时出错，要么是配置问题，要么是服务器问题，要么是数据库问题，优先考虑前者，一点一点按照ssh项目启动逻辑找问题，其次是服务器中的部署项目是不是出问题了，移除并重新部署，最后也是可能性最小的，重启数据库

解决方案五：

从你的log上看，最开始的报错不是这个吗？Caused by: Unable to load jar:file:/D:/mars-workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/vvvvvvvvvvv/WEB-INF/lib/struts2-spring-plugin-2.3.15.3.jar!/struts-plugin.xml - [unknown location]那就应该是你的那个jar包的问题吧。。。你换一个低版本的struts2-spring-plugin.jar呢？我目前用的2.3.8版本的，至少是配置上没有问题。。。
