是没加 @Service @comtroller的原因么

有加Controller

package java.web;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class Index extends DefaultController{
//@RequestMapping("/index")
@RequestMapping(value={"/index"}, method={org.springframework.web.bind.annotation.RequestMethod.GET})
//@RequestMapping(value="/index")
public String index(ModelMap modelMap){
return "/index";
}
}
