fop生成PDF支持中文(xml & xsl)

本例可將xml格式數據按xsl模板轉化爲PDF
1.首先，程序結構如下：

2.FopReport.java

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

	/**
	 * 根據xsl模板及xml數據文件生成pdf
	 * @param xsltFile xsl模板
	 * @param xmlFile xml數據文件
	 * @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;
	}

/**
	 * 根據xsl模板及xml字節數組生成pdf
	 * @param xsltFile xsl模板
	 * @param bXmlData xml字節數組 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>附加條款</Title>");
			buf.append("		<PartyA>上海信息技術有限公司B</PartyA>");
			buf.append("		<PartyB>上海信息技術有限公司B</PartyB>");
			buf.append("	</ReportHeader>");
			buf.append("	<ReportBody>");
			buf.append("		<Table>");
			buf.append("			<TableRow>");
			buf.append("				<ItemName>附加條款1</ItemName>");
			buf.append("				<ItemTime>2012-12-23 09:03</ItemTime>");
			buf.append("			</TableRow>");
			buf.append("			<TableRow>");
			buf.append("				<ItemName>上海信息技術有限公司附加條款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文檔

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

5.附字體配置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.效果圖如下：
