必须转换 html 字符串 pdf。Html 字符串包含 utf-8 字符。它不是英语。我已经尝试过现有的解决方案
这是我的maven代码。这里我使用1.3版本的itext和5.5.6版本的xmlworker。
<dependency>
<groupId>itext</groupId>
<artifactId>itext</artifactId>
<version>${itext.version}</version>
</dependency>
<dependency>
<groupId>com.itextpdf.tool</groupId>
<artifactId>xmlworker</artifactId>
<version>${xmlworker.version}</version>
</dependency>
<itext.version>1.3</itext.version>
<xmlworker.version>5.5.6</xmlworker.version>
这是我的java代码。该代码对于英语来说运行良好。它不适用于其他语言。它显示该位置的空白区域。
document = new Document();
PdfWriter docWriter = PdfWriter.getInstance(document, new FileOutputStream(file));
document.setMargins(5, 5, 25, 5);
document.setMarginMirroring(false);
Rectangle rect = new Rectangle(30, 30, 500, 800);
document.setPageSize(PageSize.A4);
rect.setBorder(Rectangle.BOX);
docWriter.setBoxSize("footer", rect);
document.open();
CSSResolver cssResolver = new StyleAttrCSSResolver();
CssFile cssFile = XMLWorkerHelper.getCSS(new ByteArrayInputStream("body {font-family:Arial, Arial Unicode MS, sans-serif}".getBytes()));
cssResolver.addCss(cssFile);
XMLWorkerFontProvider fontProvider = new XMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);
fontProvider.register("D:/opt/data/files/ttf/arialuni.ttf");
CssAppliers cssAppliers = new CssAppliersImpl(fontProvider);
// HTML
HtmlPipelineContext htmlContext = new HtmlPipelineContext(cssAppliers);
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);
InputStream inputStream = new ByteArrayInputStream(pdfFormatData.getBytes(Charset.forName("UTF-8")));
// XML Worker
XMLWorker worker = new XMLWorker(css, true);
XMLParser p = new XMLParser(worker);
p.parse(inputStream, Charset.forName("UTF-8"));
PdfPTable table = new PdfPTable(1);
PdfPCell cell = new PdfPCell();
cell.setRunDirection(PdfWriter.RUN_DIRECTION_RTL);
for (Element e : elements) {
cell.addElement(e);
}
table.addCell(cell);
document.add(table);
这是我的 html 内容

最佳答案
我认为，你应该将 utf-8 添加到你的 html 内容中，例如
<head>
<meta charset="UTF-8">
</head>
关于java - UTF-8字符html内容字符串转pdf，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57425355/
