前言

阿里云版和纯手工版详细步骤：

一、阿里云版

1.新增模块

1. File
2. Project Structure
3. Spring Initializr
4. 更改Initializr Service URL 为：https://start.aliyun.com

2.springboot联网功能

注意：java version与自己配置的jdk版本保持一致

3.选择当前模块需要使用的技术集

• 根据自己的需求选择
• 选择web
• 选择SpringWeb

4.控制类

package com.jkj.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/booksThree")
public class BookController {
    @GetMapping
    public String ById(){
        System.out.println("springboot_03 is running...");
        return "springboot_03 is running...";
    }
}

5.测试

二、纯手工版

1.新建模板-Maven

1. File
2. Project Structure
3. Maven

2.修改模块位置

3.配置依赖pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.jkj</groupId>
    <artifactId>springboot_05</artifactId>
    <version>1.0-SNAPSHOT</version>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.7.1</version>
    </parent>
    <description>Demo project for Spring Boot</description>
    <properties>
        <java.version>1.8</java.version>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>



</project>

4.编写Application入口类

package com.jkj;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

5.控制类

package com.jkj.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/bookFive")
public class BookController {
    @GetMapping
    public String ById(){
        System.out.println("springboot_05 is running...");
        return "springboot_05 is running...";
    }
}

6.测试
