开放原子开发者工作坊

用maven搭建的java web项目，上传到git仓库后，当同事clone下来项目，部署到tomcat运行时，就报了如下错误，即启动web项目时，加载web.xml文件，找不到spring的监听器，控制台错误如下：

这，这个错误真心让人醉了，究竟是怎么回事，我本地是没问题的啊，为什么同事clone下来就出了这种错误。经过半天研究后发现，不知道什么原因，clone下来后用eclipse导入maven项目后，在他那里用git status命令看了一下，有两个配置文件改变了，一个是.classpath，一个是.project，这两个文件内容变了，当我把这两个文件还原为最初状态后，项目就正常了。

虽然这样能够解决，但是终归不太完美，因为以后新人进来还会出现这种问题！

最后终于找到解决方法，感谢原作者，参考http://www.yihaomen.com/article/java/471.htm

解决方法：

1. 右键单击工程项目 ->点击 properties
2. 选择 Deployment Assembly
3. 点击 Add -> Java Build Path Entries -> Next
4. 选择 Maven Dependencies -> Finish -> Apply -> OK
5. Clean project and server. 重启server
