开始日期和结束日期是POJO中的joda dateTime,我得到的错误是:
The startdate and enddate are joda dateTime in the POJO and the error I get is:
SystemOut O 14:10:16.040 [WebContainer : 2] DEBUG org.springframework.beans.BeanUtils - No property editor [org.joda.time.DateTimeEditor] found for type org.joda.time.DateTime according to 'Editor' suffix convention ... SystemOut O Error::Failed to convert property value of type 'java.lang.String' to required type 'org.joda.time.DateTime' for property 'startTimestamp'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [org.joda.time.DateTime] for property 'startTimestamp': no matching editors or conversion strategy found我也无法编辑Pojo并添加@DateTimeFormat,因为Pojo是从XSD生成的.我也尝试添加一个customObjectMapper,但是没有任何效果.任何帮助将不胜感激.
I also can't edit the Pojo and add @DateTimeFormat because the Pojos are generated from XSD. I also tried adding a customObjectMapper, but nothing works. Any help would be much appreciated.
原始问题:
我正在尝试提交表单并将数据发送到Controller方法.问题是ModelAttribute为空并且没有值. Spring MVC Portlet + Jsp + Javascript + Jquery +控制器@ResourceMapping
I'm trying to submit a form and send the data to the Controller method. The issue is the ModelAttribute is empty and does not have the values. Spring MVC Portlet + Jsp + Javascript + Jquery + Controller @ResourceMapping
摘要:
JSP:
<portlet:resourceURL id="addNewURL" var="addNewURL"> </portlet:resourceURL> <form:form id="qmat_new_notification_form" action="#" method="POST" modelAttribute="dataObject"> ... <input type="text" class="date-picker" id="start_date"> ... <input type="submit" value="Save" class="button" onclick="addNew()"> </form:form>jQuery:
function addNew() { var dataObject = JSON.stringify({ 'startTime': $('#start_date').val(), 'endTime': $('#end_date').val(), 'description': $('#message').val(), 'active': $('#status').val() }); alert("data::"+dataObject); $.ajax({ url: "<%=addNewURL%>", type: 'POST', contentType: 'application/json', data: dataObject }).done(function(json){ alert("Success!"); //more logic }).fail(function() { alert("OOPS!"); }); }控制器:
@ResourceMapping(value = "addNewURL") public void addNew(@ModelAttribute(value = "dataObject") Obj n, BindingResult bindingResult, ResourceRequest request, ResourceResponse response, ModelMap model) { if (!bindingResult.hasErrors()) { System.out.println("a:::"+n.getDescription()); }此getDescription为空.另外,如果我使用request.getParameter("description")也为null.我想念什么?请帮助
This getDescription is null. Also if I use request.getParameter("description") is also null. What am I missing? Please help
推荐答案您根本不需要使用JSON数据.
You don't need to work with JSON data at all.
首先,避免将dataObject字符串化:
First, avoid stringification of dataObject:
var dataObject = {...}; // no JSON.stringify call第二,删除contentType: 'application/json',因为在这种情况下这没有意义.
Second, remove contentType: 'application/json' as it doesn't make sense in this case.
使用dataObject作为键/值对并使用默认的contentType,可以正确构造POST请求.
With dataObject being a key/value pair and default contentType, the POST request will be constructed correctly.
要处理单击和提交事件,我建议jQuery单击和提交方法:
To handle both click and submit events, I suggest to jQuery click and submit methods:
$("#submit").click(function (event) { addNew(); event.preventDefault(); }); $("#submit").submit(function (event) { addNew(); event.preventDefault(); });我为问题创建了小提琴.
请参见 jQuery.ajax 文档.
