Struts 2 ajax验证无法找到拦截器类jsonValidationWorkflowStack [英] Struts 2 ajax validation unable to find interceptor class jsonValidationWorkflowStack

问题描述

我试图在我的Struts 2应用程序中实现ajax验证。我在构建路径中包含了struts2-json-plugin。每当我在Eclipse中启动服务器时，都会收到以下错误：

无法找到ref-name引用的拦截器类
jsonValidationWorkflowStack - interceptor-ref -
文件：/ C：/path/struts.xml：15：60

我的struts.xml如下所示：

 < struts> 
< constant name =struts.url.includeParamsvalue =all/> 
< constant name =struts.devModevalue =true/> 
< package name =defaultextends =struts-default> 
< action name =submitFormclass =action.FormAction> 
< interceptor-ref name =jsonValidationWorkflowStack/> 
< result> results.jsp< / result> 
< result name =input> index.jsp< / result> 
< result name =error> index.jsp< / result> 
< / action> 
< / package> 
< / struts> 
  

为什么会发生这种情况？我正在遵循官方的struts2 ajax验证教程在。

解决方案

你需要扩展 -default包。

struts-default了解jsonValidationWorkflowStack。

I'm trying to implement ajax validation in my Struts 2 application. I have included struts2-json-plugin in the build path. Whenever I start the server in Eclipse, I get the following error:

Unable to find interceptor class referenced by ref-name jsonValidationWorkflowStack - interceptor-ref - file:/C:/path/struts.xml:15:60

This is what my struts.xml looks like:

<struts>
<constant name="struts.url.includeParams" value="all" />
<constant name="struts.devMode" value="true" />
<package name="default" extends="struts-default">
    <action name="submitForm" class="action.FormAction" >
        <interceptor-ref name="jsonValidationWorkflowStack"/>
        <result>results.jsp</result>
        <result name="input">index.jsp</result>
        <result name="error">index.jsp</result>
    </action>
</package>  
</struts>

Why is this happening? I'm following the official struts2 ajax validation tutorial at.

解决方案

You need to extend the "json-default" package.

The "struts-default" package doesn't know about the "jsonValidationWorkflowStack".
