在指定特定时间段时，我们准备一个Web API，该API返回该时间段内每个日期的数据。
具体来说，POST
{"targetFrom": "2016-04-01", "targetTo": "2016-04-03"}}
返回以下JSON数据。
{
"meta": {
"StartTime": "2017-06-01T06:50:28.001344102Z",
"execute_time": 7532.0517,
"host": "49a6ced149d2",
"rid": ""
},
"result": {
"2016-04-01": {
"0:num": 121,
"0:price": 5244614,
"1:num": 124,
"1:price": 6324547,
"2:num": 115,
"2:price": 5604491
},
"2016-04-02": {
"0:num": 125,
"0:price": 6321222,
"1:num": 117,
"1:price": 5835030,
"2:num": 118,
"2:price": 5771826
},
"2016-04-03": {
"0:num": 118,
"0:price": 5486071,
"1:num": 131,
"1:price": 6563447,
"2:num": 111,
"2:price": 5740078
},
"subTotal": {
"total_2016-04-01_num": 360,
"total_2016-04-01_price": 17173652,
"total_2016-04-02_num": 360,
"total_2016-04-02_price": 17928078,
"total_2016-04-03_num": 360,
"total_2016-04-03_price": 17789596
},
"total": {

}
问题是日期字段的一部分，如“2016-04-01”。 我想在SpringBoot的应用程序端接受这个，考虑处理修改，并希望定义一个合适的模型。 但是，我找不到一个好的方法。
首先，我认为以下是愚蠢的行为。
@JsonProperty("2016-04-01")
private ResAnalyzeResultDayDto result_20160401;
这是愚蠢的，因为它无法对应于在查询时依赖于参数targetFrom或targetTo的返回数据。
那么，我们如何定义一个模型来处理具有根据请求动态变化的Field的响应数据？ 如果你有个好主意，请告诉我。
附加说明： 我编写以下代码时，我的相处并不好。
@JsonProperty("[0-9]{4}-[0-9]{2}-[0-9]{2}")
private Map<String,ResAnalyzeResultSubTotalDayDto> maps;
首先，“@ JsonProperty”似乎无法使用正则表达式，我认为它不会自动设置地图的键。
请求部分的代码使用“RestTemplate”。
ReqTotalSalesStatusDto reqGoMonth = new ReqTotalSalesStatusDto();
reqGoMonth.setStrTo("2016-04-03");
reqGoMonth.setStrFrom("2016-04-01");
// Jackson2HttpMessage
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
ResponseEntity<ResAnalyzeDto> resultGoMonth = restTemplate.exchange(
"http://localhost:18000/analyze"
, HttpMethod.POST
, new HttpEntity<>(reqGoMonth)
, ResAnalyzeDto.class);

您可以将所有结果字段添加到地图对象中：
private Map<String,Object> result;
result.forEach((k,v)->{
System.out.println("key: " + k + " value: " + v);
if("total".equals(k)){
Total total = (Total) v;
} else if("subTotal".equals(k)) {
SubTotal subTotal = (SubTotal) v;
} else {
ResAnalyzeResultDayDto resAnalyzeResultDayDto = (ResAnalyzeResultDayDto) v;
}
});
之后你可以检查钥匙。至于你的例子，map值可以是3个不同的对象。 Total，SubTotal或DayInfo（ResAnalyzeResultDayDto）。您可以轻松了解总计和小计，并可以将它们转换为相应的对象类型。对于地图的其余值，他们将被投射到ResAnalyzeResultDayDto。

我按照我教的方式尝试过，但我不能在演员阵容中表现出色，现在迈出了一步。
