控制器代码：

package com.boot.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;

@RestController
public class Controller {
    @RequestMapping("/hu")
    public String hello() {
        return "hello world:";
    }
    @RequestMapping("/hu1")
    public ModelAndView hello1(HttpServletRequest request,
            HttpServletResponse response) throws Exception {
        //return "hello world1:";
        String msg="hello";
        return new ModelAndView("login", "msg", msg);
    }
}

将前缀更改为

WEB-INF/jsp/

spring.mvc.view.prefix=WEB-INF/jsp/

spring.mvc.view.prefix=WEB-INF/jsp/
