自己封裝了些FastJson中格式轉換的方法

import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.serializer.SimplePropertyPreFilter;
import java.util.ArrayList;
import java.util.List;

public class CqUtil {

    //將obj轉換成JSONArray
    public JSONArray ObjectToJSONArray(Object obj, String ...filters) {
        SimplePropertyPreFilter spp = new SimplePropertyPreFilter();
        for (String filter : filters) {
            spp.getExcludes().add(filter);
        }
       String jsonString = JSONObject.toJSONString(obj, spp, SerializerFeature.DisableCircularReferenceDetect);
        return JSONArray.parseArray(jsonString);
    }

    //將Object轉換成JSONObject
    public JSONObject ObjectToJSONObject(Object obj, String ...filters) {
        SimplePropertyPreFilter spp = new SimplePropertyPreFilter();
        for (String filter : filters) {
            spp.getExcludes().add(filter);
        }
       String jsonString = JSONObject.toJSONString(obj, spp, SerializerFeature.DisableCircularReferenceDetect);
        return JSONObject.parseObject(jsonString);
    }

    //JSONArray轉換成JSONObject
    public JSONObject JsonArrayToJsonObject(JSONArray jo) throws Exception{
        JSONObject ret = new JSONObject();
        ret.put("data", jo == null ? "[]".getBytes() : jo.toJSONString().getBytes("UTF-8"));
        return ret;
    }

    //JSONObject轉換成JSONArray
    public JSONArray JSONObjectToJSONArray(JSONObject object){
        JSONArray array = new JSONArray();
        String strJson=object.toJSONString();
        array.add(strJson);
        return array;
    }

    //JSONArray轉換成List
    public List JSONArrayToList(JSONArray jsonArray){
        List list = new ArrayList();
        jsonArray.forEach(array->{
            list.add(array);
        });
        return list;
    }

}
