**1、配置spring boot的核心启动器；**

**2、添加starter模块；**

首先maven的pom.xml文件内容如下：

<?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>org.example</groupId>
        <artifactId>spring_boot</artifactId>
        <version>1.0-SNAPSHOT</version>
    
        <properties>
            <maven.compiler.source>8</maven.compiler.source>
            <maven.compiler.target>8</maven.compiler.target>
        </properties>
    
    
        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.4.5</version>
            <relativePath/> 
        </parent>
    
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
        </dependencies>
    
    
    </project>

**3、创建应用程序的App类(启动类)；**

package org.example;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    
    @SpringBootApplication
    public class helloWorldApplication
    {
    
        public static void main(String[] args)
        {
    
            SpringApplication.run(helloWorldApplication.class, args);
    
        }
    }

4、创建一个controller模块，并运行：

package org.example.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    
    @Controller
    public class HelloController
    {
    
        /*
        http://localhost:8080/hello
         */
        @ResponseBody
        @RequestMapping("/hello")
        public String hello()
        {
    
            return "Hello World!____________china";
        }
    
    
        //http://localhost:8080/123
        @ResponseBody
        @RequestMapping("/123")
        public String home123()
        {
            return "中国您好";
        }
    
    
    
        //http://localhost:8080/1234
        @RequestMapping(value = "/1234",method = RequestMethod.GET)
        @ResponseBody
        public String home1234()
        {
            return "中国您好_123456";
        }
    }
