錯誤的原因是因為使用了get方式的請求，但是又使用了@RequestBody進行數據的封裝，所以才會出現該錯誤

錯誤代碼如下：

@ApiOperation("數據數量")@GetMapping("/device/collect/data/count")@ApiOperationSupport(ignoreParameters = {"appUserDeviceId","date","modelId","param","status","start","now"})public Result<DataCount> deviceCollectDataCount(@RequestBody DataOptions dataOptions){Result<DataCount> result = new Result<>();//根據appid獲取modelIdList<Integer> modelIdList = temperatureHumidityService.getModelIdList(dataOptions.getAppId());int counts = 0;int warings = 0;for(Integer modelId : modelIdList){dataOptions.setModelId(modelId);int count = appUserDeviceDataService.selectCount(dataOptions);counts = counts + count;dataOptions.setStatus(1);int waring = appUserDeviceDataService.selectCount(dataOptions);warings = warings + waring;}DataCount dataCount = new DataCount();dataCount.setCount(counts);dataCount.setWarning(warings);result.setData(dataCount);result.setStatus(AppCode.ACCESS_SUCCESS.code);result.setMessage(AppCode.ACCESS_SUCCESS.message);return result;}

解決：

因為Get請求發送數據的方式不是json格式，所以當我們使用@RequsetBody封裝Get請求的數據時就會出現無法獲取到數據的情況

@ApiOperation("數據數量")@PostMapping("/device/collect/data/count")@ApiOperationSupport(ignoreParameters = {"appUserDeviceId","date","modelId","param","status","start","now"})public Result<DataCount> deviceCollectDataCount(@RequestBody DataOptions dataOptions){Result<DataCount> result = new Result<>();//根據appid獲取modelIdList<Integer> modelIdList = temperatureHumidityService.getModelIdList(dataOptions.getAppId());int counts = 0;int warings = 0;for(Integer modelId : modelIdList){dataOptions.setModelId(modelId);int count = appUserDeviceDataService.selectCount(dataOptions);counts = counts + count;dataOptions.setStatus(1);int waring = appUserDeviceDataService.selectCount(dataOptions);warings = warings + waring;}DataCount dataCount = new DataCount();dataCount.setCount(counts);dataCount.setWarning(warings);result.setData(dataCount);result.setStatus(AppCode.ACCESS_SUCCESS.code);result.setMessage(AppCode.ACCESS_SUCCESS.message);return result;}

也就是將get請求方式改為post請求，或者@RequsetBody注解去掉，也是可以將數據封入對象的
