springboot请求响应——响应

package com.hxy.springboot.springbootdemo01.demo01;

import com.hxy.springboot.springbootdemo01.pojo.Result;
import com.hxy.springboot.springbootdemo01.pojo.User;
import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.text.DateFormat;
import java.time.LocalDateTime;
注：@RestController=@ResponseBody+@Controller，一方面用Controller标签标记该类为控制层，一方面用@ResponseBody表明需要返回响应。
@RestController
//请求标签
public class Class3 {
注：@RequestMapping表明响应路径
    @RequestMapping("/class3")
        注：@DateTimeFormat表明映射形式为"时间"
    public Result class3(@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")LocalDateTime localDateTime) {
        System.out.println(localDateTime);
        Result result = new Result();
        return result.success(1,"success", localDateTime);
    }

    @RequestMapping("/jasonparam")
         注：@RequestBody用于标记接收的内容为响应体，对应的在Postman中的url中需要使用jason格式进行发送
    public Result jasonparam(@RequestBody User user) {
        System.out.println(user.toString());
        Result result = new Result();
        return result.success(1,"success", user);
    }

    @RequestMapping("/jasonparam2")
        注：本响应接口与上述响应接口不同的地方在于没有使用@RequestBody标签，所以postman中也对应的是直接在Url中添加对应属性内容
    public Result jasonparam1( User user) {
        System.out.println(user.toString());
        Result result = new Result();
        return result.success(1,"success", user);
    }

    @RequestMapping("/path/{id}/{name}")
        注：@PathVariable表明响应的是一个路径格式，标签中需要与形参的名字相对应
    public Result pathtest(@PathVariable int id, @PathVariable String name) {
        System.out.println(id);
        System.out.println(name);
        Result result = new Result();
        return result.success(1,"success", id+name);
    }
}
