Liferay 7 Freemarker模板 - 獲取文章分類

嗨夥伴Liferay'ers，Liferay 7 Freemarker模板 - 獲取文章分類

我試圖用Freemarker模板得到一個journalArticle的類別。

我試過這段代碼：

<#assign journalArticleId = .vars['reserved-article-id'].data> 
<#assign journalArticleResourceLocalServiceUtil = staticUtil["com.liferay.portlet.journal.service.JournalArticleResourceLocalServiceUtil"]> 
<#assign assetCategoryLocalServiceUtil = staticUtil["com.liferay.portlet.asset.service.AssetCategoryLocalServiceUtil"]> 

<#assign articleResourcePK = journalArticleResourceLocalServiceUtil.getArticleResourcePrimKey(groupId, journalArticleId)/> 
<#assign categoryList=assetCategoryLocalServiceUtil.getCategories("com.liferay.portlet.journal.model.JournalArticle",articleResourcePK) > 

<#list categoryList as categoryList> 
${categoryList.getName()} 
</#list>

當我執行的代碼，它拋出這個錯誤：

08:26:30,582 ERROR [http-nio-8080-exec-10][runtime:60] Error executing FreeMarker template 
FreeMarker template error: 
The following has evaluated to null or missing:

---- 
Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??

有沒有人有一個想法是什麼，我做錯了什麼？預先感謝您。

我錯了我測試這個withi的Liferay 6.2

I tried your code that it's working for me make sure you have abilitate the services for template in portal-ext.properties
freemarker.engine.restricted.classes= 
freemarker.engine.restricted.variables= 
freemarker.engine.restricted.packages= 

在Liferay中7他們有改變的freemarker引擎的設置現在configurazion是在控制面板

Control Panel -> Configuration -> System Settings 
-> Foundation -> FreeMarker Engine -> Restricted Variables

你必須刪除這裏的限制變量在這種情況下staticUtil
