以下函数提供单个emp对象的服务

    @RequestMapping(value="/emp/{empid}",produces=MediaType.APPLICATION_JSON_VALUE)
    public Emp findEmp(@PathVariable("empid") long id) {
        Emp e=new Emp();
        e.setId(id);
        e.setAge(20);
        e.setName("Andy");
        
        return e;
    }

在Browser里的地址是

http://localhost:8080/emp/12

输出是：

{"id":12,"name":"Andy","age":20}

 

以下函数提供多个Emp对象服务：

    @RequestMapping(value="/emps",produces=MediaType.APPLICATION_JSON_VALUE)
    public List<Emp> findAllEmp() {
        
        List<Emp> ls=new ArrayList<Emp>();
        
        for(int i=0;i<10;i++) {
            Emp e=new Emp();
            e.setId(100+i);
            e.setAge(20+i);
            e.setName("Andy"+String.valueOf(i));
            
            ls.add(e);
        }
    
        return ls;
    }

在Browser里地址为：

http://localhost:8080/emps

输出是：

[{"id":100,"name":"Andy0","age":20},{"id":101,"name":"Andy1","age":21},{"id":102,"name":"Andy2","age":22},{"id":103,"name":"Andy3","age":23},{"id":104,"name":"Andy4","age":24},{"id":105,"name":"Andy5","age":25},{"id":106,"name":"Andy6","age":26},{"id":107,"name":"Andy7","age":27},{"id":108,"name":"Andy8","age":28},{"id":109,"name":"Andy9","age":29}]

 

Emp类是一个简单实体类：

package com.example.demo;

public class Emp {
    private long id;
    private String name;
    private int age;
    
    public Emp() {
        
    }
    
    public Emp(long id,String name,int age) {
        this.id=id;
        this.name=name;
        this.age=age;
    }
    
    public long getId() {
        return id;
    }
    public void setId(long 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;
    }
}
