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);
}
