用例一_get.post請求接口LocalDateTime 參數

    @GetMapping("get/localDateTime")

用例二_post _RequestBody 實體中接收LocalDateTime類型的參數

  • 實體
package cn.zhangfusheng.user.server.controller;

import java.time.LocalDateTime;

public class LocalDateTimeModel {

    private LocalDateTime createTime;

    private LocalDateTime updateTime;

    public LocalDateTime getCreateTime() {
        return createTime;
    }

    public void setCreateTime(LocalDateTime createTime) {
        this.createTime = createTime;
    }

    public LocalDateTime getUpdateTime() {
        return updateTime;
    }

    public void setUpdateTime(LocalDateTime updateTime) {
        this.updateTime = updateTime;
    }
}
  • 測試接口
    @PostMapping("post/model/localDateTime")
    @ApiOperation(value = "post 請求 localDateTime 作爲參數賦值", produces = "application/json")
    public BaseResponse<Object> postRequestBody(@RequestBody LocalDateTimeModel model) {
        return BaseResponse.success(model);
    }
  • 測試1

前端傳遞如下請求參數:
{ “createTime”: “2020-06-18T03:50:06.024Z”, “updateTime”: “2020-06-18T03:50:06.024Z”}
接口可以正常接收到參數

  • 測試1結果
    在這裏插入圖片描述
  • 測試二

傳遞如下格式的參數
{ “createTime”: “2020-06-18 03:55:02”, “updateTime”: “2020-06-18 03:55:02”}

用例三_響應給前端的數據時間格式化

  • 在用例二中可以看到返回給前端的數據格式如下
{
  "result": 200,
  "msg": null,
  "data": {
    "createTime": [
      2020,
      6,
      18,
      3,
      55,
      2
    ],
    "updateTime": [
      2020,
      6,
      18,
      3,
      55,
      2
    ]
  }
}
  • 返回給前端 yyyy-MM-dd HH:mm:ss 格式的數據 全局配置
    @Bean
    public ObjectMapper objectMapper() {
        ObjectMapper objectMapper = new ObjectMapper();
        JavaTimeModule javaTimeModule = new JavaTimeModule();
        // 序列化
