问题解答

把Spring-MVC的debug日志输入来看看！

所以你访问的url是怎么写的呢？

推荐所有web开发者通读一下http协议

springmvc-servlet.xml要放在src下吧？

看下我的博客吧 http://blog.csdn.net/yege2006...

配置文件里添加<context:annotation-config/>试试

按照这个配置 <param-value>classpath:springmvc-servlet.xml</param-value> springmvc-servlet.xml文件需要放在src目录下。 然后你确定你的项目可以启动成功？？

应该是放在src下面的
