intellij idea 开发spring boot

1.创建一个spring boot的project

输入project的名字，点击完成

2.创建controller

package com.example.demo.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by Administrator on 2018/3/12 0012.
 */
@RestController
public class TestController {
    @RequestMapping("/test1")
    public String welcome() {
        System.out.println("test1");
        return "test1";
    }

    @RequestMapping("/test2")
    public String hello1() {
        System.out.println("test2");
        return "test2";
    }
}

运行，然后 http://localhost:8080/test1

spring boot 项目启用成功

3.加入jsp，形成前后台

创建controller

package com.example.demo.controller;

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

/**
 * Created by Administrator on 2018/3/12 0012.
 */
@Controller
public class HelloController {
    @RequestMapping("/hello")
    public String welcome() {
        System.out.println("hello");
        return "hello";
    }

    @RequestMapping("/hello1")
    public String hello1() {
        System.out.println("hello1");
        return "hello1";
    }
}

创建jsp

在src/main/webapp/WEB-INF 创建hello.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
hello hello hello hello
</body>
</html>

在application.properties 里面添加

# 页面默认前缀目录
spring.mvc.view.prefix=/WEB-INF/
# 响应页面默认后缀
spring.mvc.view.suffix=.jsp

运行命令

spring-boot:run

前后台配置成功。
