手动解析Collection

即将被解析的json

{"collection": {"templates": [{"data": [{"name": "plantCode","value": "MSHG_KFXHS02"}, {"name": "details","value": [{"plantMedicamentId": 182,"plantCode": "MSHG_KFXHS02","medicamentCode": "MTRL005","medicamentName": "工业硫酸","presetsNumber": "21","dimension": "kg","creatUser": "mshg","creatTime": "2024-07-10 16:02:36","updateUser": "","updateTime": ""}]}]}]}
}

controller层，通过@RequestBody 正常接收

@SneakyThrows@Log@ApiOperation(value = "新增", notes = "装置药剂关联表数据")@PostMapping(value = "/addDemo")public void addDemo(@RequestBody String savePlantMedicamentInfo)throws Exception {plantMedicamentService.addDemoInfo(savePlantMedicamentInfo);}

service 手动解析

这块主要看怎么一层一层的解析数据并完成转换

public void addDemoInfo(String savePlantMedicamentInfo) {Gson gson = new Gson();JsonElement root = gson.fromJson(savePlantMedicamentInfo, JsonElement.class);JsonObject collectionObj = root.getAsJsonObject().getAsJsonObject("collection");JsonArray templatesArray = collectionObj.getAsJsonArray("templates");JsonArray dataObj = templatesArray.get(0).getAsJsonObject().getAsJsonArray("data");int dataSize = 0;for (JsonElement jsonElement : dataObj){if(jsonElement.getAsJsonObject().has("name")){dataSize ++;}}String value = dataObj.get(0).getAsJsonObject().get("value").getAsString();String plantCode = null;List<Detail> detailList = new ArrayList<>();for (int i=0;i<dataSize;i++){if (i==0){plantCode = dataObj.get(i).getAsJsonObject().get("value").getAsString();}else{JsonArray detailsValue = dataObj.get(i).getAsJsonObject().getAsJsonArray("value");Detail[] detail = gson.fromJson(detailsValue, Detail[].class);for (Detail data : detail){Detail detailInfo = new Detail();detailInfo.setPlantMedicamentId(data.getPlantMedicamentId());detailInfo.setPlantCode(data.getPlantCode());detailInfo.setMedicamentName(data.getMedicamentName());detailInfo.setMedicamentCode(data.getMedicamentCode());detailInfo.setPresetsNumber(data.getPresetsNumber());detailInfo.setDimension(data.getDimension());detailInfo.setCreatUser(data.getCreatUser());detailInfo.setCreatTime(data.getCreatTime());detailInfo.setUpdateUser(data.getUpdateUser());detailInfo.setUpdateTime(data.getUpdateTime());detailList.add(detailInfo);}}}JsonArray detailsValue = dataObj.get(1).getAsJsonObject().getAsJsonArray("value");log.info("测试数据如下：" + detailsValue);}

Detail实体

@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
public class Detail {private int plantMedicamentId;private String plantCode;private String medicamentCode;private String medicamentName;private String presetsNumber;private String dimension;private String creatUser;private String creatTime;private String updateUser;private String updateTime;
}

以上内容为举例，可以参考其中的某些步骤
