Springboot @RequestBody + Retrofit @Body 之实体类字段含有日期Date类型的提交方式

有时候进行参数提交时需要提交很多的参数，一个个参数写太麻烦，则可以利用POST即两者的注解直接实体类进行提交，他们会自动进行字段的映射，相当于json数据格式提交，可以省很多事，但是需要注意字段为日期Date类型时的处理。

演示代码：

springboot controller类：

@RequestMapping("addNewConference/")    public BaseResult<Conference> addNewConference(@RequestBody Conference conference) {        System.out.println(conference);        // 如果id不存在，则添加        if (conference.getConferenceId() == null) {            conference.setReleaseTime(new Date());            conference.setStatus(Conference.STATUS_SOON);            if (conferenceService.insert(conference)) {                ConferencePushUtils.PushConference(conference);//推送会议                return ResultUtils.getSuccBaseResult(conference);            } else {                return ResultUtils.getErrorBaseResult(3, "会议发布失败");            }        }        // 否则更新        conferenceService.updateById(conference);        return ResultUtils.getSuccBaseResult(conference);    }

Retrofit接口：

//发布会议    @POST("/conference/addNewConference/")    Call<BaseResult> sendNewMeeting(@Body Conference conference);

Retrofit 实例化：

Gson gson=new GsonBuilder().setDateFormat("yyyy-MM-dd HH:mm:ss").create();        Retrofit retrofit = new Retrofit.Builder().client(client).baseUrl(Api.BASE_URL)                .addConverterFactory(GsonConverterFactory.create(gson)).build();

Conference 实体类 —–关键在于给date日期加上格式化format

关键点：对实体类的Date日期类型字段进行格式化操作，且保证两者的格式化格式一致
