在pom.xml引入依赖

 
     
      org.apache.tomcat.embed  
      tomcat-embed-jasper 
    

    
    
    
      javax.servlet
      javax.servlet-api
    
    
      javax.servlet.jsp
      javax.servlet.jsp-api
      2.3.1
    
    
    
    
      javax.servlet
      jstl
    

在pom.xml的build中配置以下信息

    
      
        
        src/main/webapp
        
        meta-INF/resources
        
        
          **/*.*
        
      
    

在application.properties文件配置SpingMVC的视图展示为jsp,这里相当于mvc的配置

server.port=8080

# 配置视图解析器
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp

在webapp下新建jsp

hello.jsp

${msg}

Controller.java

package com.hashnode.mybatisreverse.controller;

import com.hashnode.mybatisreverse.model.Student;
import com.hashnode.mybatisreverse.service.StudentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.servlet.ModelAndView;

import java.util.HashMap;
import java.util.Map;

@Controller
public class HelloController {

    @GetMapping(value = "/sayhello")
    public ModelAndView sayHello(){
        ModelAndView mv = new ModelAndView();
        mv.addObject("msg","Hello!");
        mv.setViewName("hello");
        return mv;
    }

}

运行结果如下:
