java - 无法使用 docx4j 更新文档目录中的页码

问题描述

生成目录时，我无法更新页码。它将异常显示为“遇到损坏的书签；未配置为补救”。我使用下面的代码来更新 TOC ..

TocGenerator tocGenerator = new TocGenerator(wordMLPackage);

tocGenerator.generateToc(0, "TOC \o \"1-3\" \h \z \u ", false);

tocGenerator.updateToc(false);

解决方案

消息来自这里：

/**
 * Calculate page numbers
 * 
 * @return
 * @throws TocException
 */
private Map<String, Integer> getPageNumbersMap() throws TocException {

    // @since 6.1, check bookmarks are ok first
    // what to do if not ok?
    // - default behaviour is to fail
    // - but can be configured to remediate:
    boolean remediate = Docx4jProperties.getProperty("docx4j.toc.BookmarksIntegrity.remediate", false);

    // 
    BookmarksIntegrity bm = new BookmarksIntegrity();
    StringWriter sw = new StringWriter();
    bm.setWriter(sw);
    BookmarksStatus result = null;
    try {
        // Checks are performed on all bookmarks, not just those with
        // a name of the form "_Toc*".  We don't check for missing _Toc bookmarks.
        result = bm.check(wordMLPackage.getMainDocumentPart(), remediate);
    } catch (Exception e) { /* won't happen */}
    if (result==BookmarksStatus.BROKEN) {
        throw new TocException("Encountered broken bookmarks; not configured to remediate. \n" + sw.toString());
    }

    if (Docx4J.pdfViaFO()) {
        return getPageNumbersMapViaFOP();
    } else {
        // recommended
        return getPageNumbersMapViaService();
    }
}

请注意，除非您是 Plutext 的 PDF 转换器服务的现有被许可人，否则您将无法使用 getPageNumbersMapViaService()。
