1、手动配置,三个文件
打开创建maven,创建这三个文件从上到下依次复制即可
配置文件(重要)(否则后面会报错)
pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

HelloWorldMainApplication
package cn;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @SpringBootApplication 来标注一个主程序类,说明这是一个Spring Boot应用
*/
@SpringBootApplication
public class HelloWorldMainApplication {
public static void main(String[] args) {
// Spring应用启动起来
SpringApplication.run(HelloWorldMainApplication.class,args);
}
}
HelloController
package cn.ly;
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 KKK12345K!";
}
}
运行主程序
运行浏览器
第二种:
直接创建Spring initializr
创建时勾选spring web
穿件完后就不需要写
pom.xml和主类了
只要写下controller逻辑层的代码就行,依然可以运行
