Struts2中的TokenSession拦截器

[英]TokenSession interceptor in Struts2

 原文  2014-07-03 18:33:48  5   1    java/ struts2/ token/ interceptor

问题描述

I'm trying to ignore multiple user clicks in the same button using tokenSession interceptor of struts2, but I'm always getting a null pointer exception when the action should be successfully completed. 我试图使用struts2的tokenSession拦截器忽略同一按钮上的多个用户单击，但是当操作应成功完成时，我总是会收到一个空指针异常。 When a validation error happens it behaves like expected. 发生验证错误时，其行为与预期的一样。 I'd like to know what else do I need to do to get a tokenSession working besides put a <s:token /> in the form and enable the tokenSession interceptor? 我想知道除了在表单中放置<s:token />并启用tokenSession拦截器之外，还需要做什么以使tokenSession正常工作？

My struts configuration is: 我的struts配置是： 

<interceptor-stack name="mogeoDefaultStack">

                <interceptor-ref name="tokenSession"/>

                <interceptor-ref name="exception">
                    <param name="logEnabled">true</param>
                    <param name="logLevel">ERROR</param>
                </interceptor-ref>

                <interceptor-ref name="alias"/>
                <interceptor-ref name="servletConfig"/>
                <interceptor-ref name="i18n"/>
                <interceptor-ref name="prepare"/>
                <interceptor-ref name="chain"/>
                <interceptor-ref name="scopedModelDriven"/>
                <interceptor-ref name="modelDriven"/>
                <interceptor-ref name="fileUpload"/>
                <interceptor-ref name="checkbox"/>
                <interceptor-ref name="multiselect"/>
                <interceptor-ref name="staticParams"/>
                <interceptor-ref name="actionMappingParams"/>

                <interceptor-ref name="params">
                    <param name="excludeParams">dojo\..*,^struts\..*,^session\..*,^request\..*,^application\..*,^servlet(Request|Response)\..*,parameters\...*</param>
                </interceptor-ref>

                <interceptor-ref name="conversionError"/>
                <interceptor-ref name="validation">
                    <param name="excludeMethods">input,back,cancel,browse</param>
                </interceptor-ref>
                <interceptor-ref name="workflow">
                    <param name="excludeMethods">input,back,cancel,browse</param>
                </interceptor-ref>
                <interceptor-ref name="debugging"/>

            </interceptor-stack>

I already tried that token session in several places (begining, after i18n, and at the end) within the interceptor stack, but I had no success either. 我已经在拦截器堆栈中的多个位置（从i18n开始，直到最后）尝试了令牌会话，但是我也没有成功。

My action code is: 我的动作代码是： 

<action name="submitParameter" method="submitParameter" class="com.fic.mogeo.actions.ParameterAction">
            <interceptor-ref name="mogeoDefaultStack" />
            <result name="success" type="redirect">listParameters.do2</result>
            <result name="input" type="tiles">newParameter</result>
        </action>

And issued error is: 发出的错误是：

The path should be absolute 路径应该是绝对的 

<result name="success" type="redirect">/path/to/listParameters.do2</result>

If you use action name to redirect to, then better try redirectAction result type. 如果使用操作名称重定向到，则最好尝试使用redirectAction结果类型。

The "success" name of the result is default , so you can omit it. 结果的“成功”名称是default ，因此您可以忽略它。 Make sure your action returns SUCCESS result code. 确保您的操作返回SUCCESS结果代码。
