import com.xbmu.bean.Person;
import org.springframework.web.bind.annotation.*;

import java.util.ArrayList;
import java.util.List;

@RestController
@RequestMapping(value = "/person")
public class PersonController {
    @PostMapping("/postReq")
    public String postReq()
    {
        return "postReq";
    }
    @GetMapping("/getReq")
    public String getReq(String param1,String param2)
    {
        return "getReq";
    }
    @RequestMapping("/req")
    public String req(String param1)
    {
        return "req";
    }

    @RequestMapping(value = "/getPersonSingle",method = RequestMethod.GET)
    private Person getPersonSingle(Integer id){
        Person person;
        List<Person> personList = new ArrayList<>();
        for (int i = 0; i < 10; i++) {
            person = new Person();
            person.setId(i+1);
            person.setName("zhangsan"+(i+1));
            person.setGender("男"+i);
            person.setAge(18+1);
            person.setAddress("shanxi xian");
            personList.add(person);
        }
        person = personList.get(id);
        return person;
