我使用Eclipse Luna 64bit，Maven，docx4j API进行PDF转换，模板字母格式，我想要我的HTML代码。该模板保存在我的数据库中。
我想在PDF中包含一个超链接，以便我的用户可以点击此链接并在浏览器中打开它。
这是我的主要课程：

public class LetterMaintenanceBean extends BaseManagedBean implements
Serializable {
public StreamedContent previewLetter() {
String content = this.letter.getHtmlContent();
String regex = "<a href=(\"[^\"]*\")[^<]*</a>"; //Digvijay
Pattern p = Pattern.compile(regex); //Digvijay
System.out.println("p: "+p);
Matcher m = p.matcher(content); //Digvijay
System.out.println("m: "+m);
content = m.replaceAll("<strong><u><span style=\"color:#0099cc\">$1</span></u></strong>"); //Digvijay
System.out.println("regex1: "+regex); //Digvijay
Map<String, String> previewExamples = this.getPreviewExamples(this.letter.getMessageTypeCode());
for (Entry<String, String> example : previewExamples.entrySet()) {
if (StringUtils.isNotBlank(example.getKey()) && StringUtils.isNotBlank(example.getValue())) {
content = content.replace(example.getKey(), example.getValue());
System.out.println("content after map date");
}
}
System.out.println("content1:: "+content);
if (!content.startsWith("<div>")) {
content = "<div>" + content + "</div>";
}
// Docx4j does not understand HTML codes for special characters. So replacing with Unicode values.
content = content.replace(" ", " ");
content = content.replace("’", "’");
content = content.replaceAll("</p>", "</p><br/>");
content = content.replaceAll("\"</span>", "</span>");
InputStream stream = null;
try {
System.out.println("content:"+content);
if (this.letter.getHtmlContent().getBytes() != null && this.letter.getWfTemplateId() != null) {
stream = new ByteArrayInputStream(this.HTMLToPDF(content.getBytes(), this.letter.getWfTemplateId()));
} else {
stream = new ByteArrayInputStream(this.HTMLToPDFWithoutTemplate(content.getBytes()));
}
StreamedContent file = new DefaultStreamedContent(stream, "application/pdf", this.letter.getLetterName() + ".pdf");
return file;
} catch (LetterMaintenanceException e) {
this.processServiceException(e);
StreamedContent file = new DefaultStreamedContent(
new ByteArrayInputStream(
"Unable to process your request. If the problem persists, please contact application support."
.getBytes()), "application/pdf", "error" + ".pdf");
return file;
} catch (Exception e) {
this.processGenericException(e);
StreamedContent file = new DefaultStreamedContent(
new ByteArrayInputStream(
"Unable to process your request. If the problem persists, please contact application support."
.getBytes()), "application/pdf", "error" + ".pdf");
return file;
}
}
这是我的HTMLToPDF()方法：
private byte[] HTMLToPDF(final byte[] htmlContent, final String templateId)
throws Docx4JException, LetterMaintenanceException {
LetterMaintenanceDelegate letterMaintenanceDelegate = new LetterMaintenanceDelegate();
Template template = letterMaintenanceDelegate.retrieveTemplateById(templateId);
if (template == null || template.getContent() == null) {
throw new LetterMaintenanceException("Could not retrieve template");
}
InputStream is = new ByteArrayInputStream(template.getContent());
WordprocessingMLPackage templatePackage = WordprocessingMLPackage.load(is);
// Convert HTML to docx
XHTMLImporterImpl XHTMLImporter = new XHTMLImporterImpl(templatePackage);
XHTMLImporter.setHyperlinkStyle("Hyperlink");
templatePackage
.getMainDocumentPart()
.getContent()
.addAll(XHTMLImporter.convert(new ByteArrayInputStream(htmlContent), null));
// Add content of content docx to template
templatePackage.getMainDocumentPart().getContent().addAll(templatePackage.getMainDocumentPart().getContent());
// Handle page breaks
templatePackage = this.handlePagebreaksInDocx(templatePackage);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
Docx4J.toPDF(templatePackage, baos);
return baos.toByteArray();
}
}
在此代码中，我尝试将HTML（带有href标记）转换为PDF文件，而在PDF输出中，超链接必须有效。
此程序的当前输出为PDF，但其中没有可用的链接。
如何激活我的链接？
