自己封装了些FastJson中格式转换的方法

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 {

//将obj转换成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);
}

//将Object转换成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转换成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转换成JSONArray
public JSONArray JSONObjectToJSONArray(JSONObject object){
JSONArray array = new JSONArray();
String strJson=object.toJSONString();
array.add(strJson);
return array;
}

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

}
