Question

我正在使用netbeans freemarker从Entity类生成JSF页面。在list.ftl文件中，我有

 <#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具有entityDescriptor.blob或entityDescriptor.relationshipOne之类的字段，在哪里可以找到这些可能的变量，例如blob，id，valuesGetter或RelationshipOne？我已经检查了freemarker.jar源文件及其网站文档，但似乎它更可能与netbeans向导有关。

ps：我正在寻找一个ManyToMany条件，并在此之前询问它是模糊还是误导。

这取决于数据模型的实现细节，但是通常，如果可以执行entityDescriptor.blob，则entityDescriptor?keys应该给出一个包含"blob"的列表。要掌握的想法是，在FTL中，entityDescriptor.blob和entityDescriptor["blob"]完全相同，因此entityDescriptor有点像Map，带有String键（即使（不一定是Map，FTL对此的看法与此类似）。因此，您甚至可以将键值对列出为<#list entityDescriptor as k, v>，就像您自然希望从类似Map的对象中看到的那样。

Netbeans向导freemarker中的#list循环变量在哪里
