public class helloMvcController {
#RequestMapping("/mvc")
public String helloMvc()
{
return "home";
}
i search lots question like this,but no one can solved my problem,please help.

I believe, Spring can not find your controller.The problem might be with the component scan.
Please change your component scan directive from
<context:component-scan base-package="com.zhangbing.springmvc">
to
<context:component-scan base-package="com.zhangbing.springmvc.*">
Then lets see what is the output.
