<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<h1>01.jsp</h1>
<h2>${hello}</h2>
</body>
</html>

4.controller

package com.yl.springbootjsp.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class HelloController {

    @GetMapping("/hello")
    public String hello(Model model) {
        model.addAttribute("hello","hello jsp...");
        return "01";
    }
}

5.配置视图的前缀和后缀方式一

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

6.配置视图的前缀和后缀方式二

package com.yl.springbootjsp.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        registry.jsp("/WEB-INF/jsp/",".jsp");
    }
}
