1、IText實(shí)現(xiàn)html2pdf，速度快，糾錯能力差，支持中文（要求HTML使用unicode編碼），但中支持一種中文字體，開源。

2、Flying Sauser實(shí)現(xiàn)html2pdf，糾錯能力差，支持多種中文字體（部分樣式不能識別），開源。

3、PD4ML實(shí)現(xiàn)html2pdf，速度快，糾錯能力強(qiáng)，支持多種中文字體，商業(yè)。

（二）Flying Sauser

項(xiàng)目主頁：https://xhtmlrenderer.dev.java.net/依賴jar包：iText-2.0.8.jar、iTextAsian.jar、core-renderer.jar默認(rèn)情況下，core-renderer.jar對中文是不能進(jìn)行換行的，如果想解決換行問題可以去http://bettereveryday.javaeye.com/blog/611561下載一個jar包，該包對源代碼做了稍加修改.下面只是一個小的測試案例，如果項(xiàng)目中使用到了該組件可以參考API完成項(xiàng)目組中相應(yīng)的功能！ view plaincopy to clipboardprint? import java.io.File; import java.io.FileOutputStream; import java.io.OutputStream; import org.xhtmlrenderer.pdf.ITextFontResolver; import org.xhtmlrenderer.pdf.ITextRenderer; import com.lowagie.text.pdf.BaseFont; public class TestFlyingSauser { public static void main(String[] args) throws Exception { demo_1(); demo_2(); } // 不支持中文 public static void demo_1() throws Exception { String inputFile = "D:/Test/flying.html"; String url = new File(inputFile).toURI().toURL().toString(); String outputFile = "D:/Test/flying.pdf"; OutputStream os = new FileOutputStream(outputFile); ITextRenderer renderer = new ITextRenderer(); renderer.setDocument(url); renderer.layout(); renderer.createPDF(os); os.close(); } // 支持中文 public static void demo_2() throws Exception { String outputFile = "D:/Test/demo_3.pdf"; OutputStream os = new FileOutputStream(outputFile); ITextRenderer renderer = new ITextRenderer(); ITextFontResolver fontResolver = renderer.getFontResolver(); fontResolver.addFont("C:/Windows/fonts/simsun.ttc", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); StringBuffer html = new StringBuffer(); // DOCTYPE 必需寫否則類似于 這樣的字符解析會出現(xiàn)錯誤 html.append("<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">"); html.append("<html xmlns=\"http://www.w3.org/1999/xhtml\">").append("<head>") .append("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\" />") .append("<mce:style type=\"text/css\"><!-- body {font-family: SimSun;} --></mce:style><style type=\"text/css\" mce_bogus="1">body {font-family: SimSun;}</style>") .append("</head>") .append("<body>"); html.append("<div>支持中文！</div>"); html.append("</body></html>"); renderer.setDocumentFromString(html.toString()); // 解決圖片的相對路徑問題 // renderer.getSharedContext().setBaseURL("file:/F:/teste/html/"); renderer.layout(); renderer.createPDF(os); os.close(); } } import java.io.File; import java.io.FileOutputStream; import java.io.OutputStream;import org.xhtmlrenderer.pdf.ITextFontResolver; import org.xhtmlrenderer.pdf.ITextRenderer;import com.lowagie.text.pdf.BaseFont;public class TestFlyingSauser { public static void main(String[] args) throws Exception { demo_1(); demo_2(); }// 不支持中文 public static void demo_1() throws Exception { String inputFile = "D:/Test/flying.html"; String url = new File(inputFile).toURI().toURL().toString(); String outputFile = "D:/Test/flying.pdf"; OutputStream os = new FileOutputStream(outputFile); ITextRenderer renderer = new ITextRenderer(); renderer.setDocument(url); renderer.layout(); renderer.createPDF(os); os.close(); }// 支持中文 public static void demo_2() throws Exception { String outputFile = "D:/Test/demo_3.pdf"; OutputStream os = new FileOutputStream(outputFile); ITextRenderer renderer = new ITextRenderer(); ITextFontResolver fontResolver = renderer.getFontResolver(); fontResolver.addFont("C:/Windows/fonts/simsun.ttc", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); StringBuffer html = new StringBuffer(); // DOCTYPE 必需寫否則類似于 這樣的字符解析會出現(xiàn)錯誤 html.append("<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">"); html.append("<html xmlns=\"http://www.w3.org/1999/xhtml\">").append("<head>").append("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\" />").append("<mce:style type=\"text/css\"><!-- body {font-family: SimSun;} --></mce:style><style type=\"text/css\" mce_bogus="1">body {font-family: SimSun;}</style>").append("</head>").append("<body>"); html.append("<div>支持中文！</div>"); html.append("</body></html>"); renderer.setDocumentFromString(html.toString()); // 解決圖片的相對路徑問題 // renderer.getSharedContext().setBaseURL("file:/F:/teste/html/"); renderer.layout(); renderer.createPDF(os); os.close(); } } http://bettereveryday.javaeye.com/blog/611561參考資料：http://yongboy.javaeye.com/blog/510976http://www.51itsns.com/sns/space.php?uid=4&do=blog&id=582關(guān)于Flying Sauser的一篇非常不錯的文章：http://today.java.net/pub/a/today/2007/06/26/generating-pdfs-with-flying-saucer-and-itext.html
