Itext 实现 html转换成pdf
需要的jar包: core-renderer.jar 和 iText-2.0.8.jar
Html代码
<!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
">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>test</title>
<style type="text/css">
body {
font-family: SimSun;
font-size:22px;
font-style:italic;
font-weight:bold;
color:#00F;
}
</style></head>
<body>
显示中文dsklahsdal;das哈哈哈哈<br />
上多哈考虑的哈
</body>
</html>
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"/
