structs2返回json格式不知道怎么返回

Question

Action中返回HQL多表查询的结果，不知道在structs中怎么获取json格式，得不到数据...
请高手帮忙，急求帮忙...谢谢

Answer 1

利用专门的json包，设置成struts2的一个intercepter,然后数据输入和输出就可以利用json数据格式了

Answer 2

现在已经是json格式了，只是取不出来它的结构和数据，怎么打出来它的格式呢

Answer 3

你是要在页面中得到数据吗，那可以利用下JQuery直接得到JSON数据，再按JSOn的对象处理吧。呵呵，

Answer 4

想用structs2正则表达式来获取数据

Answer 5

已经获取了json格式的数据，如下:
[JSON]{"objList":[[{"activeFalg":"Y","localHostIp":"127.0.0.1","localHostName":"me","plantCd":"NJ01","timeStamp":"2011-05-14 10:33:24066000","trxDate":"2011--5-14 09:00:00","trxMode":"AddNew","trxUserId":"ADMINISTRATOR","userGroupId":"ADMINISTRATOR","userGroupName":"ADMINISTRATOR"},{"activeFlag":"Y","gender":"M","id":{"plantCd":"NJ01","userId":"ADMINISTRATOR"},"organId":"IT","password":"123","trxDate":"2011-05-09 13:00:00","trxUserId":"ADMINISTRATOR","userName":"ADMIN"}],[{"activeFalg":"Y","localHostIp":"127.0.0.1","localHostName":"me","plantCd":"NJ01","timeStamp":"2011-05-14 10:33:24075000","trxDate":"2011--5-14 09:00:00","trxMode":"Modify","trxUserId":"ADMINISTRATOR","userGroupId":"ADMINISTRATOR","userGroupName":"ADMINISTRATOR"},{"activeFlag":"Y","gender":"M","id":{"plantCd":"NJ01","userId":"ADMINISTRATOR"},"organId":"IT","password":"123","trxDate":"2011-05-09 13:00:00","trxUserId":"ADMINISTRATOR","userName":"ADMIN"}]]}请问这种格式在Ext.data.Record.create中该怎么解析数据呢?

Answer 6

楼主你把struts都写错了，你知道吗？？
呵呵，

Answer 7

到到这种格式之后直接转换成js对象就可以了eval("dataObj="+msg);// 将返回的json串转换为js对象，msg就是你上面获取到的json格式的数据 alert(dataObj.objList.length);// personList就是在存放在json里面的字符串的名字                  for(var i=0; i<dataObj.objList.length; i++){                     var obj=dataObj.objList[i];                     alert(obj.activeFalg);                  }
LZ参考下

Answer 8

//声明Json对象，将list数组中的值转换成json数据格式
JSONArray json = JSONArray.fromObject(mapList); 
response.setContentType("text/html");
response.setCharacterEncoding("UTF-8");
PrintWriter out = response.getWriter();

out.print(json);

out.flush();
out.close();
return NONE;人然后在前段用JS解析JSON就可

Answer 9

//声明response对象
HttpServletResponse response=ServletActionContext.getResponse();
