Question

将Map渲染到freemarker模板表时出错。下面是我从控制器获得的实际值的地图。

Map<Object, Object> hramonths ={4={id=4, empjoindate=16 Nov 2007, description=Apr-2012, editable=T}, 5={id=5, empjoindate=16 Nov 2007, description=May-2012, editable=T}, 6={id=6, empjoindate=16 Nov 2007, description=Jun-2012, editable=T}, 7={id=7, empjoindate=16 Nov 2007, description=Jul-2012, editable=T}, 8={id=8, empjoindate=16 Nov 2007, description=Aug-2012, editable=T}, 9={id=9, empjoindate=16 Nov 2007, description=Sep-2012, editable=T}, 10={id=10, empjoindate=16 Nov 2007, description=Oct-2012, editable=T}, 11={id=11, empjoindate=16 Nov 2007, description=Nov-2012, editable=T}, 12={id=12, empjoindate=16 Nov 2007, description=Dec-2012, editable=T}, 1={id=1, empjoindate=16 Nov 2007, description=Jan-2013, editable=T}, 2={id=2, empjoindate=16 Nov 2007, description=Feb-2013, editable=T}, 3={id=3, empjoindate=16 Nov 2007, description=Mar-2013, editable=T}}

从我的控制器

现在我想将此值呈现给我的freemarker模板，如

<#list hramonths as indication>
                <tr>
                    <td class="center">
                        <#list monthlyrent as rent>
                            <#if indication.id == rent.month><input type="hidden" name="locationIndicatorId_${indication.id}" value="${indication.id}" /> </#if>
                        </#list>    
                    </td>
                    <td class="center">
                        ${indication.description}  <input type="hidden" name="month_${indication.id}" id="month_${indication.id}" value="${indication.id}" />
                    </td>
                    <td class="center">
                        <# assign varIndicatorId ="">
                        <#list monthlyrent as rent>
                            <#if indication.id == rent.month>
                                <# assign varIndicatorId = ${rent.Indicator}>
                            </#if>
                        </#list>                    
                        <select name="indicator_${indication.id}" <#if indication.editable == "F"> disabled="true" </#if> <#if editable == false>disabled="true"</#if>>
                            <#list indicators as indicator>
                                <option value="${indicator.cid}" <#if indicator.cid == varIndicatorId> selected </#if>>
                                    ${indicator.description}
                                </option>
                            </#list>
                        </select>
                    </td>
                    <td class="right">
                        <#if mothlyrentsize != "0">

                                #if($editable == false)

                                #end

                        </#if>  
            </td>                               
        </tr>
    </#list>

但我收到错误

Expected collection or sequence. hramonths evaluated instead to freemarker.template.SimpleHash on line 199, column 40 in WEB-INF/classes/com/greytip/cougar/module/epayroll/v2/freemarker/salary/it-declaration.ftl. The problematic instruction: ---------- ==> list hramonths as indication [on line 199, column 33 in WEB-INF/classes/com/greytip/cougar/module/epayroll/v2/freemarker/salary/it-declaration.ftl] ----------  Java backtrace for programmers: ---------- freemarker.template.TemplateException: Expected collection or sequence. hramonths evaluated instead to freemarker.template.SimpleHash on line 199, column 40

如何在桌子上呈现它请任何人帮助我。

Answer 1

将Map替换为List。所以它看起来像：

List<Object> hramonths =[
    {id=4, empjoindate=16 Nov 2007, description=Apr-2012, editable=T}, 
    {id=5, empjoindate=16 Nov 2007, description=May-2012, editable=T}, 
    {id=6, empjoindate=16 Nov 2007, description=Jun-2012, editable=T}]

您可以使用map中的所有值：

Collection<Object> hramonthsValues = hramonths.values();

Answer 2

当Map使用除String之外的其他内容作为键时，freemarker并不能理解。用Map<Object, Object>替换Map<String, Object>可能会解决您的例外情况。但是你需要使用＆＃34; name＆＃34;属性以唯一标识您的对象，也作为Map的关键字。

在freemarker表中呈现Map <string，object> </string，object>
