1、新建一个SpringBoot的项目


-
这边的包名可根据自己修改

-
依赖可选可不选,尽量后期自己加
第四步.png
-
核对名称
第五步.png

建好之后左右如下图所示

2、起步小练习
- pom.xml添加依赖
<?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">

<groupId>com.springboot</groupId>
<artifactId>quickstart</artifactId>

</properties>
<dependencies>

<build>

<plugin>

</build>
</project>
- HelloController类
package com.springboot.quickstart.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
/**
*SpringBoot的第一个RESTful请求
*/
@RestController
public class HelloController {
@RequestMapping(value = "/hello",method = RequestMethod.GET)
public String getHello(){
return "Hello,Spring Boot";
}
}
- Application启动主类
package com.springboot.quickstart;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* SpringBoot的启动主类
*/
@SpringBootApplication
public class QuickstartApplication {
public static void main(String[] args) {
SpringApplication.run(QuickstartApplication.class, args);
}
}
-
看到这两行代表运行成功

之后在postman中运行,如图所示
