入门案例Maven搭建SpringBoot工程

一、引入依赖

引入依赖

<?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.william</groupId><artifactId>day01_springboot_helloworld</artifactId><version>1.0-SNAPSHOT</version><properties><maven.compiler.source>1.8</maven.compiler.source><maven.compiler.target>1.8</maven.compiler.target></properties><!--配置起步父依赖--><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.1.6.RELEASE</version></parent><dependencies><!--web开发的起步依赖--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency></dependencies></project>

二、DemoApplication

package com.william;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;/*** @author ：lijunxuan* @date ：Created in 2019/6/27  16:34* @description ：* @version: 1.0*//*** SpringBootApplication* 代表当前类是一个SpringBoot的启动引导类*/
@SpringBootApplication
public class DemoApplication {public static void main(String[] args) {// SpringApplication.run启动当前的Spring应用//第一个参数：当前类的字节码文件//第二个参数：主函数的参数SpringApplication.run(DemoApplication.class,args);}
}

三、controller

package com.william.controller;import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;/*** @author ：lijunxuan* @date ：Created in 2019/6/27  16:45* @description ：* @version: 1.0*/
@RestController
public class HelloController {@RequestMapping("/hello")public  String hello() {return "hello World";}
}
