2

获得rest-spring-mvc.zip 

解压后，IDEA导入该项目。

在com.wsc.restspringmvc下创建pojo,然后创建Person类

package com.wsc.restspringmvc.pojo;

public class Person {
   private long id;
   private String name;

    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;
    }
}

3

在com.wsc.restspringmvc下创建controller,然后创建PersonRestController

package com.wsc.restspringmvc.controller;

import com.wsc.restspringmvc.pojo.Person;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class PersonRestController {

    @GetMapping("/person/{id}")
    public Person person(@PathVariable Long id, @RequestParam(required = false) String name){
        Person per=new Person();
        per.setId(id);
        per.setName(name);
        return per;
    }
}

4 运行RestSpringMvcApplication.java

浏览器输入：

http://localhost:8080/person/1?name=袅袅炊烟

结果：

{"id":1,"name":"袅袅炊烟"}

注意：

1.IDEA中Alt+4可切换到console
