前台一个json格式的数组,后台怎样写才能接收,并解释?先创建两个类:Test和testbean,首先自己弄一个类似的json字符串(需要自己转化一下格式哦):
map对象:{Status=200, Message=查询成功, Paging={
"PageSize":2,"TotalRecords":250,"PageIndex":1},
OrderNumber=ECI2019061819433684318720,
Result=[
{"KeyNo":"4659626b1e5e43f1bcad8c268753216e",
"StartDate":"2012-07-10 00:00:00",
"Status":"在业",
"No":"110108015068911",
"CreditCode":"9111010859963405XW",
"OperName":"程维",
"Name":"北京小桔科技有限公司"},
{"KeyNo":"4178fc374c59a79743c59ecaf098d4dd",
"StartDate":"2015-04-22 00:00:00",
"Status":"存续",
"No":"440301112653267",
"CreditCode":"91440300334945450M",
"OperName":"王举",
"Name":"深圳市小桔科技有限公司"}
]
}
下面是两个类的内容:
import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;

打印出来的内容是:
