参考官方文档：
Getting Started
创建maven工程
引入依赖
4.0.0 org.example com.shu1.0-SNAPSHOT org.springframework.boot spring-boot-starter-parent2.3.4.RELEASE org.springframework.boot spring-boot-starter-web8 8
创建主程序
package com.zs.boot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class MainApplication {
public static void main(String[] args) {
SpringApplication.run(MainApplication.class,args);
}
}
编写业务
package com.zs.boot.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HelloController {
@RequestMapping("/hello")
public String handle01(){
return "Hello spring boot2";
}
}
直接运行main方法

简化配置
以后所有的配置都可以在这里写，例如：端口号修改为8888
简化部署
org.springframework.boot spring-boot-maven-plugin
打jar包
