Alfresco :覆盖 ftp 中的文件时增加文档版本

swe*_*mon 1 ftp alfresco

我想在覆盖 ftp 中的文件时增加次要文档版本。当我跟踪代码时,ContentDiskDriver2.truncateFile()适用于覆盖文件。在这个函数中我用它versionService来增加版本。以下代码编写在 truncateFile() try {

    NodeRef nodeRef = getNodeForPath(tree, DriverContent.FILE_OPEN_PARAMS.getPath());
    System.out.println("Node Ref: " + nodeRef);

    // Increase minor version to file.
    Map<String, Serializable> versionProperties = new HashMap<String, Serializable>(2, 1.0f);
    versionProperties.put(Version.PROP_DESCRIPTION, "");
    versionProperties.put(VersionModel.PROP_VERSION_TYPE, VersionType.MINOR);

    VersionService versionService = (VersionService) applicationContext.getBean("versionService");
    versionService.createVersion(nodeRef, versionProperties);
} catch (FileNotFoundException e) {
    e.printStackTrace();
}

但不幸的是我得到了这个错误。

你能帮我解决事务必须处于活动状态并且需要同步的问题吗

我找到了这个链接.. Alfresco 存储库文档版本历史记录可以通过 CIFS/FTP 获取吗?

您被“小字母”与“大字母”露天服务所困扰

“小信”服务是原始服务,通常仅在其他 Alfresco 低级服务中使用。“Big Letter”服务是面向用户的封装服务,包括交易、审计、安全等。

对于您的情况,您需要使用大字母形式,因此更改行

VersionService versionService = (VersionService) applicationContext.getBean("versionService");

到正确的一个:

VersionService versionService = (VersionService) applicationContext.getBean("VersionService");

您将获得包含交易、安全性等的 VersionService 副本,我认为这正是您的情况所需要的。(请注意,bean 是通过大首字母而不是小字母获取的)
