idea社区版创建spring boot项目(使用maven方式创建)

环境:

idea:社区版

 

1.创建maven项目

 

 

2.项目结构

这里右键main节点创建目录

 

 

 

 

3.各文件内容

App.java

package org.example;


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

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

 

HelloController.java

package org.example.controller;

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

@RestController
@RequestMapping("/api")
public class HelloController {

    @GetMapping("/hello")
    public String hello() {
        return "Hello, Spring Boot!";
    }
}

 

application.properties

server.port = 8888

 

 

pom.xml

<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">

  <groupId>org.example</groupId>
  <artifactId>demo</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>jar</packaging>

  <name>demo</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>3.1.3</version>
  </parent>

  <dependencies>

    <!--    web依赖-->
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>

  </dependencies>

</project>

这里先要配置好maven,参考步骤7的maven配置说明 

 

 

org.springframework.boot版本查看如下链接：

https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter?

 

 

 4.运行

 

 

 

6.接口调用

http://localhost:8888/api/hello

 

 

7.说明

maven设置
