Struts 2 ajax验证找不到拦截器类jsonValidationWorkflowStack

2022-01-16 00:00:00 validation ajax java struts2 dojo

我正在尝试在我的 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，都会出现以下错误:

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:

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

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

这就是我的 struts.xml 的样子:

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>

为什么会这样?我正在关注官方的 struts2 ajax 验证教程 在.

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

推荐答案

需要扩展"json-default"包.

"struts-default" 包不知道 "jsonValidationWorkflowStack".
