后台接收前端JSON数组转换成List

前端

var PaxNames = new Array();
var PaxIds = new Array();

    for(var i= 1; i<=3;i++){
              var paxName = {};

              var paxId = $('#paxId_'+i+'').val();
              var paxType = $('#paxType_'+i+'').val();
              var userName = $('#userName_'+i+'').val();

创建集合元素并赋值

              paxName.PaxId=paxId;
              paxName.PaxType=paxType;
              paxName.content=userName;
              PaxNames.push(paxName);
      }

前端转换成JSON

JSON.stringify(PaxNames)

后台用String PaxNames接收。用JSONArray转换成List

1、用Map<String.Object>接收

JSONArray jArray= JSONArray.fromObject(PaxNames);

Collection collection = JSONArray.toCollection(jArray, Map.class);

Iterator it = collection.iterator();
while (it.hasNext()) {
Map<String, Object> map = (Map<String, Object>) it.next();

List.add(map);

}

2、用Bean接收

JSONArray jArray= JSONArray.fromObject(PaxNames);

Collection collection = JSONArray.toCollection(jArray, Bean.class);

Iterator it = collection.iterator();
while (it.hasNext()) {
Bean bean= (Bean) it.next();

List.add(map);

}
