json里面包含json数组

首先需要这个依赖

<dependency>
    <groupId>net.sf.json-lib</groupId>
    <artifactId>json-lib</artifactId>
    <version>2.4</version>
    <classifier>jdk15</classifier>
</dependency>

然后需要引入两个包

import net.sf.json.JSONArray;
import net.sf.json.JSONObject;

下面就是代码例子

JSONObject jsonParam = new JSONObject();
JSONArray array = new JSONArray();
for(PPayOrderBill bill:pPayOrderBillList){
   jsonParam.put("receivableId",bill.getBillId());
   array.add(jsonParam);
}
JSONObject object = new JSONObject();
if(pPayOrderResult != null && params != null) {
  object.put("paymentId",pPayOrderResult.getGuid());
  object.put("houseId", pPayOrderResult.getHourceGuid());
  object.put("paymentList", array);
}
