1.0 引入springboot相关jar包

<?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

        <groupId>groupId</groupId>
        <artifactId>org.xyd</artifactId>
        <version>1.0-SNAPSHOT</version>
    
    
        
        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.1.0.RELEASE</version>
        </parent>
    
        <dependencies>
            
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
        </dependencies>
    
    </project>

2.0 直接开发controller

package com.xyd;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.AutoConfigurationPackage;
    import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @org.springframework.stereotype.Controller
    @EnableAutoConfiguration
    public class Controller {
    
        @RequestMapping("/hello")
        @ResponseBody
        public String getMessage(){
            return "hello ";
        }
    
        public static void main(String[] args) {
            SpringApplication.run(Controller.class,args);
        }
    }
    
    运行程序--输入http://localhost:8080/  ok至此  一个javaweb应用就开发完了

说明:我们看到只做了两件事  
一. 引入pom

二.直接开发controller
