Question

I am getting error while rendering Map to freemarker template table. below is the map what i am getting from controller with actual values.

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}}

我现在要从我的控制者那里把这一价值变成像我这样的自由标志模板。

<#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>

but i am getting error

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

如何在表格上填写,请任何人帮助我。

Answer 1

替换为<代码>Map。因此,它希望:

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}]

你们能够利用所有价值观:

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

Answer 2

freemarker doesn t understand well when a Map uses something else than a String as a key. Replacing your Map<Object, Object> by a Map<String, Object> may resolve your exception. But you will need to use a "name" attribute to uniquely identify your Object, and also as a key for the Map.
