Java代码

package com.test;

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 ITextRendererTest {     

        public static void main(String[] args) throws Exception {     

                String inputFile = "WebRoot/a.html";     

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

                String outputFile = "WebRoot/a.pdf";     

                System.out.println(url); 

                OutputStream os = new FileOutputStream(outputFile);     

                ITextRenderer renderer = new ITextRenderer();     

                renderer.setDocument(url);     

     

                // 解决中文支持问题     

                ITextFontResolver fontResolver = renderer.getFontResolver();     

                fontResolver.addFont("C:/Windows/Fonts/SIMSUN.TTC", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);     

     

                // 解决图片的相对路径问题     

//                renderer.getSharedContext().setBaseURL("file:/D:/z/temp/");     

                     

                renderer.layout();     

                renderer.createPDF(os);     

                     

                os.close();     

        }     

}  

 

注意事项:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">     

<html xmlns="http://www.w3.org/1999/xhtml ">  

(1)头文件必须这个,否则会报以下错误:

             错误:“The declaration for the entity "HTML.Version" must end with '>'.”

  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

(2)charset 必须是UTF-8,否则会报以下错误:

             错误:“Invalid byte 1 of 1-byte UTF-8 sequence.”

(3)需要定一个样式:body {font-family: SimSun};

(4)html页面必须严格遵循, 该打引号就要打引号

             错误:cellpadding=0 ,border=1"

(5)不要引用无效的链接

  <link rel="stylesheet" type="text/css" href="XX/ll.css"/ >

 <link rel="stylesheet" type="text/css" href="XX/main.css"/ >
