package com.example;
import org.springframework.web.bind.annotation.requestmapping;
import org.springframework.web.bind.annotation.restcontroller;
@restcontroller
public class hellocontroller {
@requestmapping ( "/hello" )
public string hello() {
return "hello,this is a springboot demo" ;
}
}

7.程序自动生成的springbootdemoapplication,会有一个@springbootapplication的注解,这个注解用来标明这个类是程序的入口

package com.example;
import org.springframework.boot.springapplication;
import org.springframework.boot.autoconfigure.springbootapplication;
//入口
@springbootapplication
public class springbootdemoapplication {
public static void main(string[] args) {
springapplication.run(springbootdemoapplication. class , args);
}
}
|
@springbootapplication开启了spring的组件扫描和springboot的自动配置功能,相当于将以下三个注解组合在了一起
(1)@configuration:表名该类使用基于java的配置,将此类作为配置类
(2)@componentscan:启用注解扫描
(3)@enableautoconfiguration:开启springboot的自动配置功能
8.运行springbootdemoapplication类
测试:
在地址栏中输入http://localhost:8080/hello
9.使用启动jar包的方式启动
(1)首先进入项目所在目录,如果是mac系统在项目上右键,选择reveal in finder,windows系统在项目上右键选择show in explorer,即可打开项目所在目录
(2)打开终端,进入项目所在目录
cd /users/shanml/ideaprojects/springbootdemo
输入mvn install,构建项目
(3)构建成功后,在项目target文件夹下会多出一个jar包
(4)使用java -jar springbootdemo-0.0.1-snapshot.jar
启动jar包即可
