package handlers;
import Model.User;
import org.springframework.http.HttpRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
//正确的包
import org.springframework.web.servlet.*;
@RequestMapping("/HelloWorld")
@Controller
public class HelloWorld {
private static final String SUCCESS="success";
@RequestMapping("TestModelAndView")
public ModelAndView testModelAndView(){
ModelAndView mv=new ModelAndView(SUCCESS);
mv.addObject("name","miao");
return mv;
}
}
应该导入 org.springframework.web.servlet.ModelAndView;
实际导入 org.springframework.web.portlet.ModelAndView;
