SpringBoot Maven入门

1.创建 maven 项目
2.导入 maven 依赖
3.创建主类 Application.class
4.进行测试

0.总体书写逻辑

1.使用 idea
点击 File->New ->Project -> Maven

2.导入 maven 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.lsy.springboot</groupId>
    <artifactId>01-springboot-20200824-HelloWorld</artifactId>
    <version>1.0-SNAPSHOT</version>


    <!--继承父级的依赖-->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.2.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>
        <java.version>1.8</java.version>
    </properties>

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

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

3.创建主配置类 Application**

package com.lsy;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {

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

4.编写测试
创建 HelloController 类

package com.atguigu.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HelloController {


    @RequestMapping("/hello")
    public @ResponseBody String Hello(){

        return "hello spring boot" ;
    }
}

5.进行测试
使用 http://localhost:8080/hello 测试即可
