java - where are the #list looped variables in Netbeans wizard freemarker

问题描述

I'm using netbeans freemarker to generate JSF pages from Entity classes. in list.ftl file I have 

 <#list entityDescriptors as entityDescriptor>
                        <#if entityDescriptor.id != "id" && entityDescriptor.id != "version">
                        <div class="ui-g-12 ui-md-6 ui-lg-4">
                                <p:outputLabel styleClass="template-labels" 
                                    value="${r"#{"}${bundle}.${entityDescriptor.id?replace(".","_")}${r"}"}" for="@next" />
                            <#if entityDescriptor.dateTimeFormat?? && entityDescriptor.dateTimeFormat != "">
                            <p:inputMask mask="9999/99/99" id="${entityName}_editForm_${entityDescriptor.id?replace(".","_")}" value="${r"#{"}${managedBean}.selected${entityName}.${entityDescriptor.name?replace("item.","")}${r"}"}" 
                                         converter="JalaliDateConverter" onfocus="serp.showDatePicker(this)" styleClass="PersianDate template-fields" title="${r"#{"}${bundle}.${entityDescriptor.id?replace(".","_")}${r"}"}"
                                         disabled="${r"#{"}!${managedBean}.${entityName?uncap_first}Editable${r"}"}"/>
                            <#elseif entityDescriptor.returnType?matches(".*[Bb]+oolean")>
                            <p:selectBooleanCheckbox styleClass="template-fields" id="${entityName}_editForm_${entityDescriptor.id?replace(".","_")}" 
                                                     value="${r"#{"}${managedBean}.selected${entityName}.${entityDescriptor.name?replace("item.","")}${r"}"}"
                                                     disabled="${r"#{"}!${managedBean}.${entityName?uncap_first}Editable${r"}"}"/>
                            <#elseif entityDescriptor.blob>
                            <p:inputTextarea styleClass="template-fields" id="${entityName}_editForm_textArea" rows="4" cols="30" id="${entityDescriptor.id?replace(".","_")}" 
                                             value="${r"#{"}${entityDescriptor.name}${r"}"}" title="${r"#{"}${bundle}.${entityDescriptor.id?replace(".","_")}${r"}"}"
                                             disabled="${r"#{"}!${managedBean}.${entityName?uncap_first}Editable${r"}"}"/>
                            <#elseif entityDescriptor.relationshipOne>
                            <p:selectOneMenu styleClass="template-fields" id="${entityName}_editForm_${entityDescriptor.id?replace(".","_")}" value="${r"#{"}${managedBean}.selected${entityName}.${entityDescriptor.name?replace("item.","")}${r"}"}"
                                             disabled="${r"#{"}!${managedBean}.${entityName?uncap_first}Editable${r"}"}">
                                <f:selectItem itemLabel="${r"#{"}${bundle}.SelectOneMessage${r"}"}"/>
                                <f:selectItems value="${r"#{"}${entityDescriptor.valuesGetter}${r"}"}" var="${entityDescriptor.id?replace(".","_")}Item" itemValue="${r"#{"}${entityDescriptor.id?replace(".","_")}Item${r"}"}" itemLabel="${r"#{"}${entityDescriptor.id?replace(".","_")}Item.name${r"}"}"/>
                            </p:selectOneMenu>
                            <#elseif entityDescriptor.relationshipMany>
                            <p:selectManyMenu styleClass="template-fields" id="${entityName}_editForm_${entityDescriptor.id?replace(".","_")}" value="${r"#{"}${entityDescriptor.name}${r"}"}"
                                              disabled="${r"#{"}!${managedBean}.${entityName?uncap_first}Editable${r"}"}">
                                <f:selectItems value="${r"#{"}${entityDescriptor.valuesGetter}${r"}"}" var="${entityDescriptor.id?replace(".","_")}Item" itemValue="${r"#{"}${entityDescriptor.id?replace(".","_")}Item${r"}"}"/>
                            </p:selectManyMenu>
                        <#elseif entityDescriptor.id != "id" && entityDescriptor.id != "version">
</#list>

entityDescriptor has fields like entityDescriptor.blob or entityDescriptor.relationshipOne, where can I find these possible variables like blob, id, valuesGetter or relationshipOne? I've checked the freemarker.jar source and their website documentation but it seems it's more likely related to netbeans wizard.

ps: I'm looking to find a ManyToMany condition and asked it before which was vague or misleading anyway.

解决方案

这取决于数据模型的实现细节，但通常如果你能做到entityDescriptor.blob，那么entityDescriptor?keys应该给出一个包含"blob"其他内容的列表。要掌握的想法是，在 FTL 中entityDescriptor.blob和entityDescriptor["blob"]完全相同，所以entityDescriptor有点像Map键String（即使它不一定是 a Map，FTL 也看到它与此类似）。因此，您甚至可以将键值对列为，就像您对-like 对象<#list entityDescriptor as k, v>的自然期望一样。Map
