com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException

出现这种问题的情况是由于JSON里面包含了实体没有的字段导致反序列化失败。

序列化的代码

@Override
public ResultDTO<HbZxVerifyStateDTO> getVerifyState(String type, String id) {
        try {
            String resultStr = webservice.getggStatus(DesHelper.DESEnCode(type, encryptKey),
                    DesHelper.DESEnCode(id, encryptKey), platformCode);
            logger.debug("-------------  getggStatus result is:" + resultStr);
            //问题出现再下面的一行
            HbZxVerifyStateDTO verifyStateDTO = JsonHelper.readValueCustom(resultStr, HbZxVerifyStateDTO.class);
            ResultDTO<HbZxVerifyStateDTO> result = new ResultDTO<HbZxVerifyStateDTO>();
            result.setSuccess(true);
            result.setData(verifyStateDTO);
            return result;
        } catch (Exception e) {
            throw new ServiceException("审核状态失败！", e);
        }
    }

Unrecognized field "shdw" (class com.sino.ebid.hbzx.dto.HbZxVerifyStateDTO)

由这个报错信息可以看出，我的HbZxVerifyStateDTO类中没有定义shdw这个属性，导致的序列化失败

解决

本来就是添加个字段的事情，可是因为我看错了

{"yj":"公告字段scopeofbid为空，公告code=S1301000274001258001001无需审批核准备案的，不再推送监管部门.","bj":"2","shdw":{}}

以至于shdw的属性数据类型选择错误,居然用ArrayList来接 -------》如果属性的类型不对，还会报其他类型的反序列化错误

正确的应该Object或者Map类的来接
