錯(cuò)誤的原因是因?yàn)槭褂昧薵et方式的請(qǐng)求，但是又使用了@RequestBody進(jìn)行數(shù)據(jù)的封裝，所以才會(huì)出現(xiàn)該錯(cuò)誤

錯(cuò)誤代碼如下：

@ApiOperation("數(shù)據(jù)數(shù)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(jù)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?yàn)镚et請(qǐng)求發(fā)送數(shù)據(jù)的方式不是json格式，所以當(dāng)我們使用@RequsetBody封裝Get請(qǐng)求的數(shù)據(jù)時(shí)就會(huì)出現(xiàn)無法獲取到數(shù)據(jù)的情況

@ApiOperation("數(shù)據(jù)數(shù)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(jù)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(qǐng)求方式改為post請(qǐng)求，或者@RequsetBody注解去掉，也是可以將數(shù)據(jù)封入對(duì)象的

總結(jié)
