我尝试使用导入从“网站”页面导入包含portlet，JournalFolders和JournalArticles的LAR文件。
但是我得到以下例外：

带有密钥2的JournalFolder存在于LAR包中，但不存在于数据库中（数据库已清除）。
有任何建议如何让Liferay导入文件夹吗？ （手动创建文件夹超出范围，因为我需要导入大约2000个文件夹。）
提前致谢。
答案 0 :(得分：0)
问题是我们错过了Liferay主要Portlet的一个XML文件。修复引用后，导入工作正常，文件夹可以解析。
因此，如果您遇到相同的问题（导入时文件夹丢失，尽管文件夹位于LAR包中）：确保在manifest.xml中引用主portlet文件夹（15）中的portlet.xml，然后从此portlet.xml指向同一主portlet的portlet-data.xml。
