 <!-- spring boot 父節點依賴,引入這個之後相關的引入就不需要添加version配置，spring boot會自動選擇最合適的版本進行添加。 -->

三、HelloController.java

package com.fs;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

    @RequestMapping("/getDemo")
    public Demo getDemo() {
        Demo demo = new Demo();
        demo.setId(1);
        demo.setName("張三");
        return demo;
    }
}

四、Demo.java

package com.fs;

public class Demo {

    private int    id;
    private String name;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

五、APP.java

package com.fs;

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

@SpringBootApplication
public class App {

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

}
