       File rep = new File("C:\\Cry_ReportERP006.rpt");


        /* Read a test document <em>doc</em> into a POI filesystem. */
        final POIFSFileSystem poifs = new POIFSFileSystem(new FileInputStream(rep));
        final DirectoryEntry dir = poifs.getRoot();
        DocumentEntry dsiEntry = null;
        try
        {
            dsiEntry = (DocumentEntry) dir.getEntry(DocumentSummaryInformation.DEFAULT_STREAM_NAME);
        }
        catch (FileNotFoundException ex)
        {
            /*
             * A missing document summary information stream is not an error
             * and therefore silently ignored here.
             */
        }

        /*
         * If there is a document summry information stream, read it from
         * the POI filesystem.
         */
        if (dsiEntry != null)
        {
            final DocumentInputStream dis = new DocumentInputStream(dsiEntry);
            final PropertySet ps = new PropertySet(dis);
            final DocumentSummaryInformation dsi = new DocumentSummaryInformation(ps);
            final SummaryInformation si = new SummaryInformation(ps);


            /* Execute the get... methods. */
            System.out.println(si.getAuthor());

推荐答案

请在此处找到示例代码 - Appache POI 如何

Please find the sample code here- Appache POI how to

简而言之，你可以监听MyPOIFSReaderListener:

In brief, you can a listener MyPOIFSReaderListener:

    SummaryInformation si = (SummaryInformation)
             PropertySetFactory.create(event.getStream());
    String title = si.getTitle();
    String Author= si.getLastAuthor();
    ......

并将其注册为:

    POIFSReader r = new POIFSReader();
    r.registerListener(new MyPOIFSReaderListener(),
                   "\005SummaryInformation");
    r.read(new FileInputStream(filename));
