Question

您好我创建了一个只有1个可重复的Web内容字段的简单结构。在我的模板中，我有以下代码：

<#if WebContent75zf.getSiblings()?has_content>
    <#list WebContent75zf.getSiblings() as cur_WebContent75zf>
        <!-- Web Content Start -->
        ${cur_WebContent75zf.getData()}
        <!-- Web Content End -->
    </#list>
</#if>

期望的结果是显示呈现的每个Web内容或至少获取其数据。我得到的是以下内容，我想知道我做错了什么......

<!-- Web Content Start --> 

{"className":"com.liferay.journal.model.JournalArticle","classPK":"40952"} 

<!-- Web Content End --> 
<!-- Web Content Start --> 

{"className":"com.liferay.journal.model.JournalArticle","classPK":"40971"} 

<!-- Web Content End -->
<!-- Web Content Start --> 

{"className":"com.liferay.journal.model.JournalArticle","classPK":"40990"} 

<!-- Web Content End -->

Answer 1

这个：{"className":"com.liferay.journal.model.JournalArticle","classPK":"40971"}是你通过JournalArticleLocalService检索所选Web内容所需要的，你只需得到这样的classPK：

<#if WebContent75zf.getSiblings()?has_content>
    <#list WebContent75zf.getSiblings() as cur_webContent>
        <#assign cur_webContent_map = cur_webContent.getData()?eval>
        <#assign cur_webContent_classPK = cur_webContent_map.classPK>

        <#assign article = JournalArticleLocalService.getLatestArticle(cur_webContent_classPK?number)>

    </#list>
</#if>

Answer 2

在使用之前定义journalArticleLocalService：

＆lt; #assign journalArticleLocalService = serviceLocator.findService（＆＃34; com.liferay.journal.service.JournalArticleLocalService＆＃34;）/＆gt;

Answer 3

这在Liferay 7.0中有效。确保在Liferay设置中禁用了受限变量

<#-- Liferay 7.0 -->
<#-- Make sure restricted variables are disabled in Liferay settings -->

<#assign 
    serviceContext = staticUtil["com.liferay.portal.kernel.service.ServiceContextThreadLocal"].getServiceContext()
    themeDisplay = serviceContext.getThemeDisplay()
    group_id = themeDisplay.getScopeGroupId()                    
    JournalArticleLocalService = serviceLocator.findService("com.liferay.journal.service.JournalArticleLocalService")

<#if WebContent75zf.getSiblings()?has_content>
        <#list WebContent75zf.getSiblings() as cur_webContent>
                <#assign 
                    cur_webContent_map = cur_webContent.getData()?eval
                    cur_webContent_classPK = cur_webContent_map.classPK
                    article = JournalArticleLocalService.getLatestArticle(cur_webContent_classPK?number)
                    article_id = article.articleId
                    article_content = JournalArticleLocalService.getArticleContent(group_id, article_id, null, locale, themeDisplay)
                >

                ${article_content}

        </#list>
</#if>
