ExtJS Ajax请求因JSON数据失败

Question

I am sending modified record using extjs ajax to java side rest service ,Here is code..

Ext.Ajax.request( {
                        url : saveUrl,
                        params: {unitMonthList: Ext.JSON.encode(jsonData)},
                        method : "POST",
                        isUpload : true,
                        timeout: 300000,
                        jsonData : jsonData,
                        success : function(resp, opts) {
                            var value = resp.responseText;
                            var result = JSON.parse(value);
                            Ext.MessageBox.hide();
                            if(result.success){
                                    var umCostStore = Ext.data.StoreManager.lookup('Unitmonths');
                                    umCostStore.commitChanges();
                                    Ext.MessageBox.hide();
                                    Ext.Msg.show({
                                        title : 'Notification',
                                        msg : 'Data saved successfully!',
                                        buttons : 1,                                
                                        cls : 'msgBtnCls'
                                    });
                            }
                        },
                        failure : function(resp, opts) {
                            Ext.MessageBox.hide();
                            Ext.Msg.show({
                                title : 'Notification',
                                msg : 'Error occurred. Please try again later..',
                                buttons : 1,                                
                                cls : 'msgBtnCls'
                            });
                        }
                    });




@POST
@Path("saveUnitMonths")
@Produces("application/json")
public String saveUnitMonths(@Context HttpServletRequest request,
        @Context ServletContext servletContext) throws ParseException {
    Gson gson = new Gson();
    String unitMonthList = request.getParameter("unitMonthList");

    }

above code working fine up to 5 records,but for more than 5 records ajax request failed giving me 500 error code and executing failure call back function. It's not calling server side at all. Please help me to understand whats going wrong for more than 5 record. if i removed Ext.JSON.encode(jsonData) and use jsonData directly then Ajax calling server side for more than 5 record also but i can't handle that non JSON data at server side.

Thanks,

Answer 1

Are you sending your data twice? In your request there is jsonData in

params: {unitMonthList: Ext.JSON.encode(jsonData)},

and once again in

jsonData : jsonData

Maybe try removing one of them.

我已经通过删除Ext.JSON.encode（jsonData）解决了这个问题，其中Ext.JSON.encode（ ）函数无法对超过5条的记录进行编码，所以我只是将jsonData：jsonData作为数组发送到服务器而没有进行编码。
