Freemarker不分配staticUtil [英] Freemarker does not assign staticUtil

问题描述

我在liferay 6.2上处理了应用程序显示模板，我使用freemarker帮助分页了liferay的动态数据列表.当我升级到liferay 7时，这是一个问题. Liferay 7使用代码<#assign records = ddlDisplayTemplateHelper.getRecords(reserved_record_set_id)>来获取记录.

I worked Application Display Templates on liferay 6.2, I use freemarker help pagination the dynamics data list of liferay. When I upgrade to liferay 7, it is a problem. Liferay 7 use code <#assign records = ddlDisplayTemplateHelper.getRecords(reserved_record_set_id)> for get a records.

旧代码:

<#assign DDLRecordLocalService = serviceLocator.findService("com.liferay.portlet.dynamicdatalists.service.DDLRecordLocalService")> <#assign records = DDLRecordLocalService.getRecords(reserved_record_set_id)> <#assign totalRecord = DDLRecordLocalService.getRecordsCount(reserved_record_set_id, 0) >

<#assign DDLRecordLocalService = serviceLocator.findService("com.liferay.portlet.dynamicdatalists.service.DDLRecordLocalService")> <#assign records = DDLRecordLocalService.getRecords(reserved_record_set_id)> <#assign totalRecord = DDLRecordLocalService.getRecordsCount(reserved_record_set_id, 0) >

它不起作用.

所以我尝试<#assign serviceLocator = staticUtil["com.liferay.portal.template.ServiceLocator"]>，但是staticUtil遇到错误.

So I try <#assign serviceLocator = staticUtil["com.liferay.portal.template.ServiceLocator"]> but staticUtil get an error.

以下内容评估为null或丢失: ==> staticUtil [在第9行第27列的模板"20115#20159#21387"中] 提示:如果已知失败的表达式在法律上是指有时为空或缺失的内容

The following has evaluated to null or missing: ==> staticUtil [in template "20115#20159#21387" at line 9, column 27] Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing

在portal-ext.properties中，我添加了:

In portal-ext.properties I have added:

freemarker.engine.restricted.classes=
freemarker.engine.restricted.packages=
freemarker.engine.restricted.variables= 

推荐答案

您引用的属性已移至Liferay 7/DXP中的OSGI配置. 要部署它们，您需要创建一个名为 com.liferay.portal.template.freemarker.configuration.FreeMarkerEngineConfiguration.cfg 的文件，并将其放置在

The properties you refer to have been moved to an OSGI config in Liferay 7/DXP. To deploy them you need to create a file named com.liferay.portal.template.freemarker.configuration.FreeMarkerEngineConfiguration.cfg and place it under $LIFERAY_HOME/osgi/configs

文件内容如下:

restrictedVariables=

要查找所有配置及其默认设置，请查看类com.liferay.portal.template.freemarker.configuration.FreeMarkerEngineConfiguration

To find all the configs and their defaults you can have a look at the class com.liferay.portal.template.freemarker.configuration.FreeMarkerEngineConfiguration

您可以在Liferay源代码中找到.

That you can find in the Liferay source code.
