itext实现HTML转换为PDF

1、首先，建立一个maven工程（maven工程的建立这里不在演示）

1.1 在maven工程的pom.xml中加入itext所需的jar包

<!-- itext 生成PDF jar--><dependency> <groupId>com.lowagie</groupId><artifactId>itext</artifactId><version>2.0.8</version></dependency> <!-- https://mvnrepository.com/artifact/org.xhtmlrenderer/core-renderer --><dependency><groupId>org.xhtmlrenderer</groupId><artifactId>core-renderer</artifactId><version>R8</version></dependency>

2、建立一个类Demo1.Java

package com.shawsuper;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 Demo1 {/** HTML转换为PDF* */public  void  HtmlToPdf(String inputFile,String outputFile) throws Exception{String url = new File(inputFile).toURI().toURL().toString();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/<span style="color:#FF0000;">simsun</span>.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();}public static void main(String[] args) throws Exception {Demo1 demo = new Demo1();String inputFile = "D://Test//iText1.jsp";String outputFile = "D://Test//123.pdf";demo.HtmlToPdf(inputFile, outputFile);}
}

3、运行main方法即可

<span style="font-size:18px;">iText1.jsp的源码
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>Insert title here</title>
<style type="text/css">           
<span style="color:#FF0000;">body {       font-family: SimSun;  //特别重要，否则中文将无法显示
}  </span>     
</style>
</head>
<body><p >迷你校</p><div class="text">个人简历</div><table border='1' bgcolor="#00FF00"><tr><td>number</td><td>name</td></tr><tr><td>1</td><td>ch</td></tr><tr><td>2</td><td>es</td></tr></table><p>教育经历ss</p><p>12422</p><p>jiaoyujingli</p></body>
</html>
</span>

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"/ >
