如何以编程方式创建Liferay 7结构?

本文介绍了如何以编程方式创建Liferay 7结构?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

在Liferay 7中，如何创建结构? 这是我的尝试:

In Liferay 7, how to create a structure from a Java module? Here is my attempt:

Map<Locale, String> nameMap = new HashMap<Locale, String>(); nameMap.put(Locale.JAPAN, "The name"); Map<Locale, String> descriptionMap = new HashMap<Locale, String>(); descriptionMap.put(Locale.JAPAN, "The description"); DDMForm ddmForm = DDMUtil.getDDMForm("<here goes my real JSON form>"); DDMFormLayout ddmFormLayout = DDMUtil.getDefaultDDMFormLayout(ddmForm); DDMStructureLocalServiceUtil.addStructure( 20156, // userId 33421, // groupId DDMStructureConstants.DEFAULT_PARENT_STRUCTURE_ID, // parentStructureId PortalUtil.getPortal().getClassNameId(DDLRecordSet.class), // classNameId new Long(CounterLocalServiceUtil.increment()).toString(), // structureKey nameMap, descriptionMap, ddmForm, ddmFormLayout, StorageType.JSON.toString(), 0, // type new ServiceContext() );

在数据库的DDMStructure表中创建该结构:

The structure gets created in the database's DDMStructure table:

不幸的是，它没有出现在该网站的Liferay UI中:

Unfortunately, it does not appear in that site's Liferay UI:

如何使其显示?

• 在创建过程中或加载UI时，Liferay日志中均未显示错误.
• 当我手动创建结构时，它会正确显示.
• 针对Liferay 6的问题的解决方案，我也尝试过，导致同样的问题.
• 我注意到手动创建结构时，在ResourcePermission表中添加了3行...在Java中创建结构时，我也应该创建这3个对象吗?

• No error appear in Liferay's log during creation nor when loading the UI.
• When I create a structure manually, it shows up correctly.
• The solution to this question for Liferay 6, which I tried too, leads to the same problem.
• I noticed that when creating a structure manually, 3 rows get added to the ResourcePermission table... when creating a structure in Java should I also create these 3 objects?

推荐答案

它是 classNameId 问题.用JournalArticle替换DDLRecordSet可解决此问题，使结构正确显示在Liferay的Structures UI中.

It is a classNameId problem. Replacing DDLRecordSet with JournalArticle solves the problem, making the structure show up correctly in Liferay's Structures UI.

有效的代码:

ServiceContext serviceContext = new ServiceContext(); serviceContext.setScopeGroupId(group.getGroupId()); serviceContext.setAddGroupPermissions(true); serviceContext.setAddGuestPermissions(true); serviceContext.setWorkflowAction(WorkflowConstants.ACTION_PUBLISH); Map<Locale, String> nameMap = new HashMap<Locale, String>(); nameMap.put(Locale.JAPAN, "The name"); Map<Locale, String> descriptionMap = new HashMap<Locale, String>(); descriptionMap.put(Locale.JAPAN, "The description"); DDMForm ddmForm = null; try { ddmForm = DDMUtil.getDDMForm(json); } catch (PortalException e) { log.error("Exception when parsing structure JSON", e); } DDMFormLayout ddmFormLayout = DDMUtil.getDefaultDDMFormLayout(ddmForm); long scopeClassNameId = PortalUtil.getPortal().getClassNameId(JournalArticle.class); long parentStructureId = DDMStructureConstants.DEFAULT_PARENT_STRUCTURE_ID; String storageType = StorageType.JSON.toString(); String structureKey = "my structure"; try { DDMStructure ddmStructure = DDMStructureLocalServiceUtil.addStructure( user.getUserId(), group.getGroupId(), parentStructureId, scopeClassNameId, structureKey, nameMap, descriptionMap, ddmForm, ddmFormLayout, storageType, DDMStructureConstants.TYPE_DEFAULT, serviceContext); } catch (StructureDuplicateStructureKeyException e) { log.info("Skipping creation of structure that already exists"); } catch (PortalException e) { log.error("Exception when creating structure: " + structureDefinitionFilePath, e); }
