java - 使用 struts 显示标签在页面之间导航时出错

Question

在显示标签的页面之间移动时出现以下错误:

Request [/seatreportsubmit] does not contain handler parameter named 'method'. This may be caused by whitespace in the label text.

但是，当我点击搜索按钮两次时，它会移动到下一页。

过去几天我一直在为这个问题苦苦挣扎。任何帮助将不胜感激。

这是我的一些代码:

<table width="100%" align="center">
    <tr>
        <td align="Center">
           <input type="button" class="buttonstyle" value="<bean:message key="button.search" />" onclick="searchsubmit();" styleClass="buttonstylebig">&nbsp;
           <input type="button" class="buttonstyle" value="<bean:message key="button.reset" />" onclick="clearValues();">
        </td>
    </tr>
</table>

结构配置:

<action path="/seatreportsubmit"
        type="com.ford.ape.seatreport.actionobject.SeatRprtAction"
        name="SeatReportForm" scope="request" input="seatreport.details"
        validate="true" parameter="method">
        <forward name="openSeatDetails" path="seatreport.details" />
        <forward name="showSeatDetails" path="seatreport.detailsreport" />          
</action>

瓷砖定义:

<definition name="seatreport.details" extends="base.definition">
    <put name="body" value="/jsp/SeatReport/SeatVacReport.jsp" />
</definition>
<definition name="seatreport.detailsreport" extends="base.definition">
    <put name="body" value="/jsp/SeatReport/SeatVacReportDetailed.jsp" />
</definition> 

js:

function searchsubmit()
{
if(search()==true)
{
    if(document.forms[0].seatReportType.value=='Summary Report')
     {
        document.forms[0].seatLocation.value='';
        document.forms[0].seatBuilding.value='';
        document.forms[0].seatFloor.value='';
        document.forms[0].seatType.value='';
        document.forms[0].seatStatus.value='';
        document.forms[0].seatCompany.value='';
        document.forms[0].seatDepartment.value='';
        document.forms[0].seatSubDepartment.value='';
        document.forms[0].seatLL5.value='';
        document.forms[0].seatLL6.value='';

        document.forms[0].method.value="loadPage";
        document.forms[0].submit();
    }

    else if(document.forms[0].seatReportType.value=='Detailed Report')
     {
        document.forms[0].method.value="showSeatRprt";
        document.forms[0].submit();
     }   
}
}

下面是使用的显示标签。

<display:table name="requestScope.SeatReportForm.rprtData" id="table" export="true" sort="list" requestURI="/seatreportsubmit.do"   pagesize="20" align="center"  class="table_main" width="100%">

<display:setProperty name="css.tr.odd" value="row2" />
<display:setProperty name="paging.banner.placement" value="bottom" />

 </display:table>

Answer 1

您收到的错误消息不言自明:您缺少 method 参数。

从您的代码看来您正在使用 DispatchAction .这种类型的 Struts Action 包含一堆“个性化的 execute 方法”，并使用请求参数来确定调用哪一个。在您的情况下，请求参数称为 method:

<action path="/seatreportsubmit" .... parameter="method">

这必须出现在对您的操作的所有请求中，否则 Struts 将不知道调用什么方法。

我看到您已经有两个方法，分别是 loadPage 和 showSeatRprt。你还有其他人吗？你有接收寻呼请求的吗？

当您在页面之间导航时，显示标记从其 requestURI 参数开始创建正确的请求 URL，在您的例子中为 requestURI="/seatreportsubmit.do"。我认为这是您缺少 method 参数的地方。

尝试在您的 Action 类中添加一个 handlePaging 方法，然后将显示标签的 requestURI 更改为如下所示:requestURI="/seatreportsubmit.do?method=handlePaging" 和当您浏览页面时，看看它是否获得控制权。
