使用 RIDC 将带有 ADF 输入文件的文件上传到 UCM 文件夹

Question

我正在使用 JDeveloper。在 ADF Fusion Web 应用程序中，我有一个 Input File 控件和一个 Send 按钮，它调用 bean 方法将文件上传到 UCM。如果我的文件位于我的机器上，比如说“/home/user/myfile.txt”，它就像一个魅力。如果我尝试使用输入文件，我看不到如何将文件上传到 UCM，而无需先将此文件保存到磁盘然后上传此文件。在我看来，不推荐这种做事方式。

这是我目前能够上传来自服务器工作站的文件的代码：

// RETRIEVE THE DESTINATION PATH
DataBinder binder = idcClient.createBinder();
binder.putLocal("IdcService", "COLLECTION_INFO");
binder.putLocal("hasCollectionPath", "true");
binder.putLocal("dCollectionPath", "/Contribution Folders/PDD"); // The path you are looking for
DataBinder searchFolder = idcClient.sendRequest(idcContext, binder).getResponseAsBinder();

binder = idcClient.createBinder();
binder.putLocal ("IdcService", "CHECKIN_NEW");
binder.putLocal ("dDocAuthor", "weblogic");
binder.putLocal ("dDocTitle", "myimage2.jpg");
binder.putLocal ("dDocName", "myimage2.jpg");
binder.putLocal ("dDocType", "Document");
binder.putLocal("xCollectionID", searchFolder.getLocal("dCollectionID"));
binder.putLocal ("dSecurityGroup", "Public");
binder.putLocal ("dDocAccount:", "");
binder.putLocal ("xComments", "My comment");
binder.addFile ("primaryFile", new File("/home/oracle/myimage.jpg"));

// check in the file
ServiceResponse response = idcClient.sendRequest (idcContext, binder);

如果您有任何建议，我将不胜感激。 谢谢大家！

解决办法如下：

        UploadedFile uf = (UploadedFile) inputFile1.getValue();

        DataBinder binder = idcClient.createBinder();
        binder.putLocal ("IdcService", "CHECKIN_NEW");
        binder.putLocal ("dDocAuthor", "weblogic"); // if user is admin, can specify other user
        binder.putLocal ("dDocTitle", uf.getFilename());
        binder.putLocal ("dDocName", uf.getFilename());
        binder.putLocal ("dDocType", "DigitalMedia");
        binder.putLocal("xCollectionID", getFolderCollectionId("/Contribution Folders/PDD")); // parent's folder
        binder.putLocal ("dSecurityGroup", "Public");
        binder.putLocal ("dDocAccount:", "");
        binder.putLocal ("xComments", "Montreal comment");
        binder.putLocal ("xWCTags", "Montreal");

        binder.addFile ("primaryFile", new TransferFile(uf.getInputStream(), uf.getFilename(), getByteLenght(uf.getInputStream())));

        ServiceResponse response = idcClient.sendRequest (idcContext, binder);

您已经自己找到了解决方案，所以我只想提一下，这里应该使用其他方便的 UploadFile 方法。

getFilename(); //you've got this
getLength(); //instead of getting byte length from stream
getContentType(); //available MIME

您的getFolderCollectionId("/Contribution Folders/PDD")) 是否按预期工作？

还请记住，文件仅在其大小小于 100KB 时才存储在内存中，如果大于则写入磁盘。每个请求限制为 2000KB。这些是默认值，可以在 servlet 上下文初始化参数中更改。
