Java Displaytag导出选项不工作

我使用Displaytag框架进行分页和导出。在这方面，我也使用Strut2Tiles集成

每当我调用任何action类时，它都会返回一个列表&通过Displaytag，我成功地在页面上显示了记录。因此，我的jsp页面的代码如下所示：

  <s:set name="selectedPageSize" value="selectedPageSize" scope="request"/>
        <s:set value="accountList" scope="request" name="accountList"/>
            <display:table name="accountList" export="true" class="table" requestURI="" id="accountList" pagesize="${selectedPageSize}" >
            <display:setProperty name="export.pdf" value="true" /> 
            <display:column property="id" sortable="true" class="sort-title"/>
            <display:column property="name" sortable="true"/>
            <display:column property="contactPerson" sortable="true"/>
            <display:column property="phone1" sortable="true"/>
            <display:column property="phone2" sortable="true"/>
            <display:column property="fax" sortable="true"/>
            <display:column property="email" sortable="true"/>
            <display:column property="webSite" sortable="true"/>
            <display:column property="address1" sortable="true"/>
            <display:column property="address2" sortable="true"/>
            <display:column property="countryId.name" title="Country" sortable="true"/>
            <display:column property="stateId.name" title="State" sortable="true"/>
            <display:column property="countryId.name" title="City" sortable="true"/>

            <display:column property="isDeleted" sortable="true"/>

            <display:column title="Delete">
                <s:url id="removeUrl" action="finance/deleteAccount.action">
                    <s:param name="id" value="#attr.accountList.id" />
                </s:url>
                <s:a href="%{removeUrl}" theme="ajax" targets="accountList">Remove</s:a>
            </display:column>

            <display:column  title="Update">
                <s:url id="updateUrl" action="finance/updateAccount.action">
                    <s:param  value="#attr.accountList.id" name="id"/>
                </s:url>
                <s:a href="%{updateUrl}&action=update" targets="accountlist">Update</s:a>
            </display:column>

请回答，我遇到了这个问题。

您是否尝试在web.xml中重新排序过滤器，以便DisplayTag的ResponseOverrideFilter是链中的第一个过滤器，即struts2过滤器之前？

配置DisplayTag表：

<display:table name="sessionScope.searchProviderLRSharingList"
id="row"
requestURI="/**ACTION_MAPPING_CALLED_TO_GET_THE_RESULTS**"
...
...
</display:table>

我可能误读了您的web.xml代码片段，但我不相信您正在开发portlet，因此您的项目中不需要displaytag-portlet-1.2.jar（包括它不会导致任何问题）。
