fop生成PDF支持中文(xml & xsl)

http://oudoud.iteye.com/blog/1755054

本例可将xml格式数据按xsl模板转化为PDF 
1.首先，程序结构如下： 
 
2.FopReport.java 

// Step 1: Construct a FopFactory
    private static final FopFactory fopFactory = FopFactory.newInstance();

    /**
     * 根据xsl模板及xml数据文件生成pdf
     * @param xsltFile xsl模板
     * @param xmlFile xml数据文件
     * @return ReportData
     * @throws Exception
     * @author bin.yin 2012/12/25
     */
    public static ReportData createReport(String xsltFile, String xmlFile) throws Exception {
        ReportData reportData = new ReportData();
        reportData.setContentType("application/pdf");
        fopFactory.setUserConfig("conf/fop.xml");

        // Step 2: Set up output stream.
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        try {
            // Step 3: Construct fop with desired output format
            Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, out);

            // Step 4: Setup XSLT using identity transformer
            TransformerFactory factory = TransformerFactory.newInstance();
            Transformer transformer = factory.newTransformer(new StreamSource(new File(xsltFile)));

            // Step 5: Setup input and output for XSLT transformation
            Source src = new StreamSource(new File(xmlFile));
            // Source src = new StreamSource(new StringReader(myString));

            // Step 6: Resulting SAX events (the generated FO) must be piped through to FOP
            Result res = new SAXResult(fop.getDefaultHandler());

            // Step 7: Start XSLT transformation and FOP processing
            transformer.transform(src, res);

            reportData.setData(out.toByteArray());
        } catch(Exception e) {
            throw e;
        } finally {
            out.close();
        }
        return reportData;
    }

/**
     * 根据xsl模板及xml字节数组生成pdf
     * @param xsltFile xsl模板
     * @param bXmlData xml字节数组 eg. StringBuffer buf = new StringBuffer(); buf.getBytes("UTF-8");
     * @return ReportData
     * @throws Exception
     * @author bin.yin 2012/12/25
     */
    public static ReportData createReport(String xsltFile, byte[] bXmlData) throws Exception {
        ReportData reportData = new ReportData();
        try {
            // convert xml bytes to a temp file
            File xmlFile = File.createTempFile("FOP", ".tmp");
            FileOutputStream fos = new FileOutputStream(xmlFile);
            fos.write(bXmlData);
            fos.close();

            reportData = createReport(xsltFile, xmlFile.getAbsolutePath());
            // delete temp file
            xmlFile.delete();
        } catch (Exception e) {
            throw e;
        }
        return reportData;
    }

3.拼接xml文件 

StringBuffer buf = new StringBuffer();
            buf.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
            buf.append("<ItemListReport>");
            buf.append("    <ReportHeader>");
            buf.append("        <Title>附加条款</Title>");
            buf.append("        <PartyA>上海信息技术有限公司B</PartyA>");
            buf.append("        <PartyB>上海信息技术有限公司B</PartyB>");
            buf.append("    </ReportHeader>");
            buf.append("    <ReportBody>");
            buf.append("        <Table>");
            buf.append("            <TableRow>");
            buf.append("                <ItemName>附加条款1</ItemName>");
            buf.append("                <ItemTime>2012-12-23 09:03</ItemTime>");
            buf.append("            </TableRow>");
            buf.append("            <TableRow>");
            buf.append("                <ItemName>上海信息技术有限公司附加条款1</ItemName>");
            buf.append("                <ItemTime>2012-12-23 09:03</ItemTime>");
            buf.append("            </TableRow>");
            buf.append("        </Table>");
            buf.append("    </ReportBody>");
            buf.append("    <ReportFooter>");
            buf.append("        <PrintDate>2012-12-12</PrintDate>");
            buf.append("        <ReportNo>010123456789</ReportNo>");
            buf.append("    </ReportFooter>");
            buf.append("</ItemListReport>");

4.生成PDF文档 

ReportData data = FopReport.createReport("report\\sample\\Sample.xsl", buf.toString().getBytes("UTF-8"));
            FileOutputStream fos = new FileOutputStream("D:/sample.pdf");

5.附字体配置fop.xml 

<font metrics-url="conf/fonts/SimSun.xml" kerning="yes" embed-url="conf/fonts/SimSun.ttc">
          <font-triplet name="SimSun" style="normal" weight="normal" />
          <font-triplet name="SimSun" style="normal" weight="bold" />
          <font-triplet name="SimSun" style="italic" weight="normal" />
          <font-triplet name="SimSun" style="italic" weight="bold" />
        </font>

6.效果图如下：
