在Liferay的6.2 Spring MVC中的portlet，型號屬性爲null在成形後的

Question

我試圖克隆Spring MVC的Portlet項目，但在發佈形式todo性質均爲空。

回購可以用Github。

這裏是控制器代碼

@Controller 
@RequestMapping("VIEW") 
public class ToDoListController { 

    @RenderMapping 
    public String view() { 
     return "list"; 
    } 

    @ActionMapping 
    public void save(@Valid ToDo toDo, BindingResult result, @CookieValue("JSESSIONID") String jsessionid, 
      PortletSession session, ModelMap modelMap) { 
     if (!result.hasErrors()) { 
      // could use entityManager to persist; put in session for this example 
      List<ToDo> toDos = (List<ToDo>) session.getAttribute("toDos"); 
      if (toDos == null) { 
       toDos = new ArrayList<ToDo>(); 
      } 
      toDos.add(toDo); 
      session.setAttribute("toDos", toDos); 

      modelMap.put("msg", String.format("You added a TODO: %s", toDo.getTitle())); 
     } 
    } 

    @ModelAttribute 
    private ToDo loadModel() { 
     return new ToDo(); 
    } 
} 

這裏是查看：

<%@ page contentType="text/html" %> 
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> 
<%@ taglib prefix="portlet" uri="http://java.sun.com/portlet_2_0" %> 
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %> 

<c:if test="${msg ne null}"> 
    <div class="portlet-msg-success"><c:out value="${msg}" /></div> 
</c:if> 

<portlet:actionURL var="save" /> 

<form:form modelAttribute="toDo" action="${save}" method="POST"> 
    <fieldset> 
     <legend>Add a TODO</legend> 
     <div> 
      <form:label path="title" cssStyle="display:block">Title:</form:label> 
      <form:input path="title" /> 
      <form:errors path="title" cssClass="portlet-msg-error" /> 
     </div> 
     <div> 
      <form:label path="due" cssStyle="display:block">Due (MM/DD/YYYY):</form:label> 
      <form:input path="due" /> 
      <form:errors path="due" cssClass="portlet-msg-error" /> 
     </div> 
     <div> 
      <form:label path="description" cssStyle="display:block">Description:</form:label> 
      <form:textarea path="description" /> 
      <form:errors path="description" cssClass="portlet-msg-error" /> 
     </div> 
     <div> 
      <input type="submit" value="Save" /> 
     </div> 
    </fieldset> 
</form:form> 

這裏是上下文：

你需要使用Spring MVC與Liferay的6.2時設置<requires-namespaced-parameters>false</requires-namespaced-parameters>在你的Liferay-portlet.xml中。在這個page的末尾有關於Liferay 6.2文檔的解釋。
