入参：param
出参：logParam

import com.alibaba.fastjson.parser.Feature;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;

代码

FeatureAccessoriesEntity featureAccessoriesEntity = JSONObject.toJavaObject(param, FeatureAccessoriesEntity.class);
        String logStr = new ObjectMapper().writeValueAsString(featureAccessoriesEntity);
        JSONObject logParam = JSONObject.parseObject(logStr, Feature.OrderedField);
