Struts2 - 验证和验证瓷砖参数

所以，我的场景如下。

页面通过调用带有articleId参数的newInfo.action来显示文章
表单操作将调用postComment.action
postComment.action将调用validate()
validate()返回验证错误。
* 问题就在这里，我如何返回图块并收到验证错误？

我的struts.xml

<action name="newInfo" class="org.blog.controller.NewInfo">
    <result type="tiles" name="success">NewInfo</result>
</action>
<action name="postComment" class="org.blog.controller.CommentController">
    <result type="redirectAction" name="success">newInfo?id=${articleId}</result
    <result type="redirect" name="input">newInfo.action?id=${articleId}</result>
</action>

CommentController.java

public void validate() {
    if(getName().length() == 0)
        addFieldError("name", "Name is required");
    if(getEmail().length() == 0)
        addFieldError("email", "Email is required");
    if(getCurrentURL().length() == 0)
        addFieldError("website", "Website is required");

    if(hasFieldErrors())
        System.out.println("Field error.");

}

当前，页面结果为文章页面，有“字段错误”，但页面没有显示任何字段错误。那么，有什么解决方案可以解决吗？

So, my scene is below.

The page show Article by call newInfo.action with articleId parameter
The form action will call postComment.action
postComment.action will call validate()
validate() return the validation error.
* The problem is here, how can i return to tile and getting validation error?

My struts.xml

<action name="newInfo" class="org.blog.controller.NewInfo">
    <result type="tiles" name="success">NewInfo</result>
</action>
<action name="postComment" class="org.blog.controller.CommentController">
    <result type="redirectAction" name="success">newInfo?id=${articleId}</result
    <result type="redirect" name="input">newInfo.action?id=${articleId}</result>
</action>

CommentController.java

public void validate() {
    if(getName().length() == 0)
        addFieldError("name", "Name is required");
    if(getEmail().length() == 0)
        addFieldError("email", "Email is required");
    if(getCurrentURL().length() == 0)
        addFieldError("website", "Website is required");

    if(hasFieldErrors())
        System.out.println("Field error.");

}

Current, the page result the article page, with "field error", but the page doesnt show any field error.
So, is there any solutions to fix it?

将 type="redirect" 更改为 type="chain" 请参阅： http:// /struts.apache.org/2.0.14/docs/result-types.html 了解更多详细信息。

试试这个：

<action name="postComment" class="org.blog.controller.CommentController">
         <interceptor-ref name="store">
            <param name="operationMode">STORE</param>
         </interceptor-ref>
         <interceptor-ref name="defaultStack" />        
         <result type="redirectAction" name="success">newInfo?id=${articleId}</result
         <result type="tiles" name="input">NewInfo</result>
</action>

Try this:

<action name="postComment" class="org.blog.controller.CommentController">
         <interceptor-ref name="store">
            <param name="operationMode">STORE</param>
         </interceptor-ref>
         <interceptor-ref name="defaultStack" />        
         <result type="redirectAction" name="success">newInfo?id=${articleId}</result
         <result type="tiles" name="input">NewInfo</result>
</action>
