iText XMLWorker CSSResolver 在 Java 7 到 Java 8 上产生不同的结果

Question

我的网站有一项功能，允许人们粘贴 html 评论，然后将这些评论输出为 pdf 报告。我有一个问题，从 Java 7 升级到 Java 8（没有其他代码更改）后，iText XMLWorker 和 CSSResolver 似乎输出 pdf 中的 html 表格，边框非常粗.

Java 7:

Java 8:

有人知道为什么会这样吗？是否有新的 settings/libraries for iText for Java 8 我错过了？

这是 iTextPdf 的错误吗？

用于处理用户粘贴评论的代码：

            String commentText = itemComment.getComment();

            // CSS
            CSSResolver cssResolver = new StyleAttrCSSResolver();

            // HTML
            HtmlPipelineContext htmlContext = new HtmlPipelineContext( null );
            htmlContext.setTagFactory( Tags.getHtmlTagProcessorFactory() );

            // Pipelines
            ElementList elements = new ElementList();
            ElementHandlerPipeline pdf = new ElementHandlerPipeline( elements, null );
            HtmlPipeline html = new HtmlPipeline( htmlContext, pdf );
            CssResolverPipeline css = new CssResolverPipeline(cssResolver, html);

            // XML Worker
            XMLWorker worker = new XMLWorker( css, true );
            XMLParser p = new XMLParser( worker );
            p.parse( new ByteArrayInputStream( commentText.getBytes() ) );


            String commentDate = sdf.format( itemComment.getCommentDate() );
            String commentAuthor = itemComment.getAuthor().getFirstname() + " " + itemComment.getAuthor().getSurname();
            dataTable.addCell(new Phrase(commentDate, labelFont));
            dataTable.addCell(new Phrase(commentAuthor, labelFont));

            PdfPCell commentCell = new PdfPCell();
            commentCell.setColspan( 2 );
            Phrase commentPhrase = new Phrase();
            commentPhrase.setFont( dataFont );
            if( !elements.isEmpty() )
            {
                for( Element element : elements )
                {
                    commentCell.addElement( element );
                }
            }
            else
            {
                commentPhrase.add( commentText );
                commentCell.addElement( commentPhrase );
            }
            dataTable.addCell(commentCell);

Answer 1

如我对问题的评论所述，我们遇到了一个奇怪的情况。

|Java    | iText 5.5.6 | iText 5.5.7
|7       | good        | bad
|8       | bad         | bad

经过一番调查后发现，iText 5.5.6 中的不一致是我们使用 HashMap 造成的。在Java7中，迭代器经历了某个HashMap如下：先是border-left-style，然后是border-left-width；在 Java 8 中，它是相反的。由于我们在 com.itextpdf.tool.xml.css.apply.HtmlCellCssApplier::setLeftOfBorder 中的代码取决于迭代顺序，因此我们的实现很容易受到此更改的影响。

HashMap 迭代的行为在 Java 8 中发生了变化，如您在 http://examples.javacodegeeks.com/core-java/util/hashmap/hashmap-changes-in-java-8/ 中所见。

我们意识到了这一点，并在 iText 5.5.7 中进行了修复，将 HashMap 替换为 LinkedHashMap，因为后者保证了对条目集的 'historic' 迭代。参见 https://github.com/itext/xmlworker/commit/92b2146bcb37b283863e24e5cb18ed661411387c。显然，这不是完全正确的举动，因为 Java 7 和 8 现在都得到了错误的顺序。我会将其添加到开发积压中，我们将尝试解决此问题。

编辑 1：

以下是我们正在尝试修复的最小用例。它目前在其中一个单元格周围生成一个矩形，这当然不应该发生。

<table>
  <tr>
    <td style="border-style: none; border-width: 0px;">a</td>
    <td style="border-width: 0px; border-style: none;">a</td>
  </tr>
</table>

EDIT2：此修复自 11 月 27 日发布的 iText 5.5.8 起可用
