模拟控制层代码

package com.example.controller;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import com.example.pojo.Student;/** * spring boot demo * @author XSWL pengfei.xiong * @date 2017年11月17日 */@RestController //相当于@Controller和@RequestBody 返回json@EnableAutoConfigurationpublic class HelloSpringBoot {
        @RequestMapping("/hello")    public String showHello(){        return "Hello SpringBoot!";    }    @RequestMapping("/pojo")    public Student showStudent(){        Student student = new Student(1, "show", 20);        return student;    }    @RequestMapping("/map")    public Map
    
      showMap(){        Map
     
       map = new HashMap
      
       ();        map.put("username", "张无忌");        map.put("age", 15);        return map;    }    @RequestMapping("/list")    public List
       
         showList(){        List
        
          list = new ArrayList
         
          (); Student student01 = new Student(1, "show", 20); Student student02 = new Student(1, "show", 20); list.add(student01); list.add(student02); return list; }}

如果对于上面的注解有疑问就看下这个博客:

实体类就不用说了啊

package com.example.pojo;import java.io.Serializable;public class Student implements Serializable{
        private int id;    private String name;    private int age;    public Student() {        super();    }    public Student(int id, String name, int age) {        super();        this.id = id;        this.name = name;        this.age = age;    }    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;    }    public int getAge() {        return age;    }    public void setAge(int age) {        this.age = age;    }}

最后是程序的入口

package com.example.demo;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import com.example.controller.HelloSpringBoot;@SpringBootApplicationpublic class DemoApplication{
        // 项目入口    public static void main(String[] args) {           SpringApplication.run(HelloSpringBoot.class, args);            //运行之后在浏览器中访问：http://localhost:11086/hello 默认端口8080,我这是修改后的路径    }}

补充下:修改端口在application.properties文件中加一句话: server.port=11086
