二，生成pdf，添加生成pdf所使用的字符集.注：这里字符集要和模板中使用的字符集一一致。 比如:java中使用宋体 renderer.getFontResolver().addFont("C:/Windows/Fonts/simsun.ttc", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); 那么html的body中样式必须加上 style='font-family:SimSun'，要是使用其他字符生成pdf时候，中文就会不显示生成pdf 的

//生成pdf例子

public class MyPdf {

/**

* 使用flying sauce生成pdf

* @param htmlPath c:\\Users\\dfhc\\Desktop\\1015101900000000020.html

* @param savePDFPath c:\\Users\\dfhc\\Desktop\\ssPdf.pdf

* @throws Exception

*/

public static void createPDFByFly(String htmlPath,String savePDFPath) throws Exception{

// step 1

String inputFile = htmlPath;

String url = new File(inputFile).toURI().toURL().toString();

String outputFile = savePDFPath;

// System.out.println(url);

// step 2

OutputStream os = null;

try {

os=new FileOutputStream(outputFile);

org.xhtmlrenderer.pdf.ITextRenderer renderer = new org.xhtmlrenderer.pdf.ITextRenderer();

// linux：

// fontResolver.addFont("/usr/share/fonts/TTF/ARIALUNI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);

renderer.getFontResolver().addFont("C:/Windows/Fonts/simsun.ttc", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);

renderer.setDocument(url);

renderer.layout();

renderer.createPDF(os);

renderer.finishPDF();

} catch (Exception e) {

// TODO: handle exception

throw new RuntimeException(e.getMessage());

}finally{

if (os != null) {

try {

os.close();

} catch (IOException e) {

// ignore

}

}

}

}

public static void main(String[] args) {

try {

createPDFByFly("c:\\Users\\dfhc\\Desktop\\1000101900000000015.html", "c:\\Users\\dfhc\\Desktop\\1000101900000000015.pdf");

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

} 三、设置pdf的页面大小模板页面中添加该样式：@page { size: 8.5in 11in; }这时候生成pdf页面正好是A4纸大小 四、所需的jar包http://download.csdn.net/detail/shiyuqiong/8343881，该核心jar是修改后的
