如何继承拦截器堆栈并覆盖其中的拦截器之一？

Question

我需要将 paramsPrepareParamsStack 拦截器堆栈继承到 mystack 中，并且需要覆盖验证拦截器参数。我该怎么做？

Answer 1

下面的代码执行得很好..

<interceptors>
            <interceptor-stack name="ehspre2stack">
                <interceptor-ref name="paramsPrepareParamsStack">
                    <param name="validation.excludeMethods">
                        list,loadedit,remove,execute,reset,loadAdd
                    </param>
                    <param name="exception.logEnabled">true</param>
                    <param name="exception.logLevel">ERROR</param>
                </interceptor-ref>
            </interceptor-stack>
        </interceptors>

只需将整个堆栈复制到 struts.xml 中并根据需要覆盖参数：

       <interceptor-stack name="paramsPrepareParamsStack">
            <interceptor-ref name="exception"/>
            <interceptor-ref name="alias"/>
            <interceptor-ref name="params"/>
            <interceptor-ref name="servletConfig"/>
            <interceptor-ref name="prepare"/>
            <interceptor-ref name="i18n"/>
            <interceptor-ref name="chain"/>
            <interceptor-ref name="modelDriven"/>
            <interceptor-ref name="fileUpload"/>
            <interceptor-ref name="checkbox"/>
            <interceptor-ref name="staticParams"/>
            <interceptor-ref name="params"/>
            <interceptor-ref name="conversionError"/>
            <interceptor-ref name="validation">
                <param name="excludeMethods">your,methods,skip,validation</param>
            </interceptor-ref>
            <interceptor-ref name="workflow">
                <param name="excludeMethods">your,methods,skip,validation</param>
            </interceptor-ref>
        </interceptor-stack>
