在XSLT中包含URL时使用fop和XSL生成PDF

Question

xsl:stylesheet xmlns:xsl=“http://www.w3.org/1999/xsl/transform”\

xmlns:fo=“http://www.w3.org/1999/xsl/format”version=“1.0”>

<xsl:include href="abc.xsl"/> 

<xsl:include href="xyz.xsl"/>

<xsl:include href="wgh.xsl"/>

这就是它在一个XSLs中包含XSLs的方式。在这种情况下，我的FOP没有重定向到那些XSL，因此无法生成PDF

错误：

private static final Logger LOG=LoggerFactory.getLogger(PdfGenerator.class);

public List<OutputStream>  generatePdfs(List<Content> xmlList, int reqestListSize,String xslPath)

{try{

    List<OutputStream> pdfOutputStreams= new ArrayList();   

    for(int p = 0; p <reqestListSize; p++) {

        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        String jaxbType = "com.abc.model"; // model package
        JAXBContext context = JAXBContext.newInstance(jaxbType);  
        Marshaller marshaller = context.createMarshaller();
        marshaller.setProperty("jaxb.formatted.output",Boolean.TRUE);
        marshaller.marshal(xmlList.get(p),bos);
        ByteArrayInputStream inStream = new ByteArrayInputStream(bos.toByteArray());                
        StreamSource xmlSource = new StreamSource(inStream);                
        // create an instance of fop factory
        FopFactory fopFactory = FopFactory.newInstance(new File(".").toURI());
        // a user agent is needed for transformation
        FOUserAgent foUserAgent = fopFactory.newFOUserAgent();

        ByteArrayOutputStream tempOutputStream = new ByteArrayOutputStream();
        Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, tempOutputStream);
        pdfOutputStreams.add(p, tempOutputStream);      
        // Setup XSLT
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        URL url = new URL(xslPath);
        InputStream xslFile = url.openStream();  (   **http://home.www.test.com/abc_web/xsl/test.xsl**  ( Using an url to get XSLT. faild loading due to XSL :include) )
        StreamSource xsltStreamSource = new StreamSource(xslFile);
        Transformer transformer = transformerFactory.newTransformer(xsltStreamSource);  
        Result res = new SAXResult(fop.getDefaultHandler());    
        // Start XSLT transformation and FOP processing
        // That's where the XML is first transformed to XSL-FO and then 
        // PDF is created      
        transformer.transform(xmlSource, res);
    }
    return pdfOutputStreams;

    }catch(Exception ex) {
        LOG.error("Error", ex);
        return new ArrayList();
    }

简单替换

URL url = new URL(xslPath);
InputStream xslFile = url.openStream();
StreamSource xsltStreamSource = new StreamSource(xslFile);

与

StreamSource xsltStreamSource = new StreamSource(xslPath);

并且XSLT处理器应该能够解析任何相关的导入或包含。
