第一种情况：确实缺少
jar 包！

    解决办法：缺少spring-web.jar,将其导入到WEB-INF/lib
目录下，build path就好了

第二种情况：tomcat的缓存问题！

    解决办法：eclipse里面的servers全部删除，然后把工程clean一下，之后重新建一个server运行。这样问题的就解决了

第三种情况：在开发中使用了 Maven ，而在 Deployment
Assembly 中没有添加 Maven！

    解决办法：打开 Build Path 中的 Configure
Build Path... ,

         找到左侧的
Deployment Assembly 点击右侧 Add...

         选中
Maven Dependencies，点击 Finish ,
