OpenOffice，将文档写入 servlet 响应

发布于 2024-09-06 19:23:11 字数 588 浏览 9 评论 0原文

目前，我们使用 OpenOffice 来获取模板文件文档中的书签，并通过 Java 将其替换为数据库中的内容。实际保存文件的代码行看起来像这样...

  XStorable storable = UnoRuntime.queryInterface(XStorable.class, document);


        // Save as Word 97 Document
        PropertyValue[] properties = new PropertyValue[1];
        PropertyValue property = new PropertyValue();
        property.Name = "FilterName";
        property.Value = FORMAT_WORD_97;
        properties[0] = property;
        storable.storeAsURL(saveFileURL, properties);

我们想直接将文件写入 servlet 响应输出流，有人知道通过 OpenOffice 的 UNO api 直接以字节数组或输入流形式获取文档的方法吗爪哇？

Currently we use OpenOffice to grab bookmarks in a template file document and replace them with content from our DB via Java. The lines of code that actually save the file look like this...

  XStorable storable = UnoRuntime.queryInterface(XStorable.class, document);


        // Save as Word 97 Document
        PropertyValue[] properties = new PropertyValue[1];
        PropertyValue property = new PropertyValue();
        property.Name = "FilterName";
        property.Value = FORMAT_WORD_97;
        properties[0] = property;
        storable.storeAsURL(saveFileURL, properties);

We want to directly write the file to the servlet response outputstream, does anybody know of a way to directly get the document as a byte array or inputstream via OpenOffice's UNO api in Java?

这取决于 UNO API 的实现。我们能够用 PDF 做到这一点，

    OutputStream os = response.getOutputStream();

    PropertyValue[] properties = new PropertyValue[2];
    PropertyValue property = new PropertyValue();
    property.Name = "FilterName";
    property.Value = FORMAT_WORD_97;
    properties[0] = property;
    PropertyValue streamProp = new PropertyValue();
    streamProp.Name = "OutputStream;
    streamProp.Value = os;
    properties[1] = streamProp;

    storable.storeAsURL("private:stream", properties);

This depends on the implementation of the UNO API. We were able to do this with PDF,

    OutputStream os = response.getOutputStream();

    PropertyValue[] properties = new PropertyValue[2];
    PropertyValue property = new PropertyValue();
    property.Name = "FilterName";
    property.Value = FORMAT_WORD_97;
    properties[0] = property;
    PropertyValue streamProp = new PropertyValue();
    streamProp.Name = "OutputStream;
    streamProp.Value = os;
    properties[1] = streamProp;

    storable.storeAsURL("private:stream", properties);

对于 10 年后遇到这个问题的人，我必须包装输出流才能使其正常工作，

PropertyValue[] properties = new PropertyValue[2];
properties[0] = new PropertyValue();
properties[0].Name = "FilterName";
properties[0].Value = "writer_pdf_Export";
properties[1] = new PropertyValue();
properties[1].Name = "OutputStream";
properties[1].Value = new OutputStreamToXOutputStreamAdapter(outputStream);
storable.storeAsURL("private:stream", properties);

如果没有这个，我就会不断遇到 com.sun.star.lang.DisposeException

For anyone running into this 10 years later I had to wrap the output stream in order to get this to work

PropertyValue[] properties = new PropertyValue[2];
properties[0] = new PropertyValue();
properties[0].Name = "FilterName";
properties[0].Value = "writer_pdf_Export";
properties[1] = new PropertyValue();
properties[1].Name = "OutputStream";
properties[1].Value = new OutputStreamToXOutputStreamAdapter(outputStream);
storable.storeAsURL("private:stream", properties);

Without this I kept running into com.sun.star.lang.DisposedException

我建议首先在本地保存文件（从 UNO API），然后在删除 [temp] 文件之前从 java 代码流式传输结果。这样做的原因是您可以将 OpenOffice 生成文档的问题与交付给客户端的问题分开。例如，如果您的文档无法生成，您可以生成错误，而不必担心部分写入的响应流式传输到客户端。另外，如果您还没有查看过工具，您可能需要查看Docmosis，它提供了冗余、性能优化和数据合并功能。它可以直接渲染到您提供的流（并且可能解决部分流结果问题）。
