apache fop生成pdf

添加依赖：

<dependency>
    <groupId>org.apache.xmlgraphics</groupId>
    <artifactId>fop</artifactId>
    <version>2.5</version>
</dependency>

定义fo模板文件：

<xsl:stylesheet version="1.1" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" exclude-result-prefixes="fo">

  <!-- ========================= -->
  <xsl:template match="projectteam">

定义xml数据：

    <name>John Doe</name>
    <function>lead</function>
    <email>[e-mail]</email>
  </member>

</projectteam>

 

生成pdf代码：

// Setup directories
File baseDir = new File(".");
File outDir = new File(baseDir, "out");
outDir.mkdirs();

// Setup input and output files
File xmlfile = new File(baseDir, "xml/xml/projectteam.xml");
File xsltfile = new File(baseDir, "xml/xslt/projectteam2fo.xsl");
File pdffile = new File(outDir, "ResultXML2PDF.pdf");

// configure fopFactory as desired
final FopFactory fopFactory = FopFactory.newInstance(new File(".").toURI());

FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
// configure foUserAgent as desired

// Setup output
OutputStream out = new java.io.FileOutputStream(pdffile);
out = new java.io.BufferedOutputStream(out);

try {
    // Construct fop with desired output format
    Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, out);

    // Setup XSLT
    TransformerFactory factory = TransformerFactory.newInstance();
    Transformer transformer = factory.newTransformer(new StreamSource(xsltfile));

    // Set the value of a <param> in the stylesheet
    transformer.setParameter("versionParam", "2.0");

    // Setup input for XSLT transformation
    Source src = new StreamSource(xmlfile);

    // Resulting SAX events (the generated FO) must be piped through to FOP
    Result res = new SAXResult(fop.getDefaultHandler());

    // Start XSLT transformation and FOP processing
    transformer.transform(src, res);
} finally {
    out.close();
}
