Spring Boot 快速创建Hello Wolrd

1. 用eclipse创建java maven项目 

2.创建HelloController类 ， src/main/java/hello/HelloController.java 

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

@Controller
@RequestMapping("/hello-world")
public class HelloController {
   @RequestMapping(method=RequestMethod.GET)
    public @ResponseBody String index() {
        return "Hello World!";
    }

}

3.创建Application 类 ，src/main/java/hello/Application.java

package hello;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.SpringApplication;

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

 

4.在 src/main/resources/application.properties 添加 server.port=8080 

5.运行 Application.java 

6. 打开浏览器访问 http://localhost:18080/hello-world 能看到 Hello Wolrd! 成功
