如何在Filenet P8中获取vwatattachment的名称、MIME类型和内容

Question

我一直试图在FileNet P8中获得vwatattachment的名称，MIME类型和内容。内容应该是字节数组或输入流。

更新:

String name = attachment.getAttachmentName();

给出VWAttachment的名称。假设通过查看文件扩展名，我可以决定适当的MIME类型。我需要知道如何在一个InputStream

中获得附件的内容

任何帮助都是感激的。谢谢!

您需要使用vwatattachment对象中的信息从Content Engine获取正确的文档。

例如:

com.filenet.api.core.Domain domain = (...you need to get this);
VWAttachment vwAttachment = (...you already have this);
ObjectStore objectStore = Factory.ObjectStore.getInstance(domain, vwAttachment.getLibraryName());
VersionSeries vs = Factory.VersionSeries.fetchInstance(objectStore, new Id( vwAttachment.getId()), null);
Document document = (Document) vs.get_CurrentVersion();
ContentTransfer contentTransfer = (ContentTransfer) document.get_ContentElements().get(0);
InputStream inputStream = contentTransfer.accessContentStream();
