SpringBoot学习笔记（一）

Maven项目

以下部分复制入pom.xml
Spring工程需要继承的父工程

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.6.2</version>
    </parent>

web开发的起步依赖

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

控制类
HelloController.java

package com.Mafu;

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 Spring Boot!";
    }
}

引导类 SrpingBoot项目的入口
HelloApplication.java

package com.Mafu;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class HelloApplication
{
    public static void main(String[] args){
        SpringApplication.run(HelloApplication.class,args);
    }

}

最后启动项目，
服务器默认地址为localhost:8080/hello
