使用Gson解析json数据

使用Gson解析带数组的json数据

json数据格式为：

{"MSG_CD":"000000","TXN_CD":"4050009","LIST":"","MSG_INF":"SUCCESS",
 "REC":[
  {"MERC_ID":"800075500050002","CRE_DT":"20160523","BUS_TYP":"0010",
  "MBL_NO":"15012400420","RN":"21","REAL_MERC_NM":"fdsgfd","MERC_NM":"fdsgfd",
  "PAY_TYP":"1","EXP_TM":"20160530092907","CRE_TM":"092907",
  "ORD_NO":"201605150000111813","ORD_DT":"20160523","ORD_STS":"RP",
  "BUS_CNL":"APP","MERC_ORD_NO":"20160523092659","ORD_AMT":"4"}]}

1.定义数据类

public class BillODBean {

private String MSG_CD;
private String MSG_INF;
public List<OrderBean> REC;

public class OrderBean{
private String CRE_DT;
private String CRE_TM;
private String ORD_STS;
private String ORD_AMT;
private String MBL_NO;
private String MERC_ORD_NO;

}
}
2.使用Gson对象解析
Gson gson = new Gson();
BillODBean billODBean = mGson.fromJson(message, BillODBean.class);
ArrayList<OrderBean> orderBeans = (ArrayList<OrderBean>) billODBean.getREC();
