form：选择spring mvc 3返回UI中的空列表 [英] form:select of spring mvc 3 returning empty list in UI
问题描述
我有一个从控制器传递到jsp页面的值列表。我有以下控制器：
I've a list of values to be passed from my controller to the jsp page. I've the below controller:
@RequestMapping(value="/addClient.do", method = RequestMethod.GET)
protected ModelAndView Submit(HttpServletRequest request, HttpServletResponse response) throws Exception {
MyForm = new MyForm();
MyForm.setClientList(MyService.getClientList(/*"30-JUN-15"*/));
System.out.println("Size of list : "+MyForm.getClientList().size()); //-- Displayed as 10 which is correct
ModelAndView model = new ModelAndView("feeMaintenance");
model.addObject("clientForm",MyForm);
model.addObject("selectedMenu", "MenuSelected");
model.addObject("clientsList",MyForm.getClientList());
return model;
}
我的jsp表格如下：
And my jsp form is as below:
<body>
<form:form method="post" modelAttribute="clientForm" action="${userActionUrl}">
<tr> <td align="left">
<form:select path="clientList">
<form:option value="-" label="------Select Client ------">
<form:options items="${clientsLists}">
</form:options></form:option></form:select>
</tr> </td>
</form>
</body>
我删除了其他不相关的代码。下拉列表仅显示---- Select Client ---即使控制器显示clientList的正确值。无法弄清楚什么是丢失的。
I've removed the additional unrelated code. The drop down only shows ----Select Client--- even though the controller shows the correct values of the clientList. Unable to figure out whats missing.
