Question

我在struts2中使用display-tag将表导出到excel表中。当我下载工作表时，它下载得很好，但会发出此警告：

com.opensymphony.xwork2.util.logging.commons.CommonsLogger warn
WARNING: Error setting expression '6578706f7274' with value '[Ljava.lang.String;@17e4898'

我在JSP文件中的显示表是：

<display:table class='displayTable' id='orderList' name='orderList' list='orderList' export="true" requestURI="listOrders" cellpadding="0" cellspacing="0" decorator="com.sanyasi.Decorator.OrderListingDataEntryDecorator">
               <display:setProperty name="export.excel" value="true"/>
                <display:setProperty name="export.excel.filename" value="order_details.xls" />

                <display:column title="Action" property="action"></display:column>
                <display:column title="Patient Name" property="patientName"></display:column>
                <display:column title="Patient Phone" property="patientPhone"></display:column>
                <display:column title="Disease" property="disease"></display:column>
                <display:column title="Call Agent" property="callAgent"></display:column>
                <display:column title="Order Status" property="orderStatus"></display:column>
                <display:column title="Delivery Mode" property="deliveryMode"></display:column>
                <display:column title="Delivery Status" property="deliveryStatus"></display:column>
                <display:column title="Delivered By" property="deliveryBy"></display:column>
                <display:column title="Delivery Date" property="deliveryDate"></display:column>
                <display:column title="Details" property="detail"></display:column>
            </display:table>

当我点击export时，display-tag会自动生成此URL

http://localhost:8084/myaction.action?d-3682230-e=2&6578706f7274=1

OGNL仅支持在Java中很好地形成的名称属性，这些名称不能以数字开头。

您无法避免此警告

警告：设置表达式'6578706f7274'时出错，值为'[Ljava.lang.String; @ 73e4'
