这篇博客主要介绍了如何在Java中创建PDF文件，从JSP页面出发，通过Action调用来实现这一过程，虽然没有详细展示接口代码，但重点在于实际的实现类部分。

jsp 页面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<!doctype html>
<html>
<head>
<%@ include file="/WEB-INF/pages/globalweb/head/pagehead_v5.ini"%>
</head>
<body>


<iframe src="" marginwidth="0" target="_self"  id="faFrame"
	marginheight="0" frameborder="0" width="100%" height="945px" 
     style="overflow-x: hidden; overflow-y: auto;">

</iframe>

</body>
<script type="text/javascript">
	$("#faFrame").attr("src",$.getURL(_path + "/fagl/faxxck_dyxx.html? 
   id=${faxx_id}"+'&dlbs='+$("#dlbs").val()));
	
</script>
</html>

Action 调用

	public String dyxx(){
		ByteArrayOutputStream bous = null;
		try{
				StringBuffer title = new StringBuffer("");
				title.append(faxxckModel.getfamc());
				//开始生成pdf
				bous = service.createPdf(title,faxxckModel);

				this.fileName = new String((title.toString() + ".pdf").getBytes(), "ISO8859-1");
				this.inputStream = new ByteArrayInputStream(bous.toByteArray());
				return Result.PDF_INLINE;
		} catch (Exception e) {
			logException(e);
			return ERROR;
		}finally{
			IOUtils.closeQuietly(bous);
		}
	}

接口不写了

直接实现类

@Override
	public ByteArrayOutputStream createPdf(PyfaxxckModel model)  throws DocumentException, IOException, ParseException, com.itextpdf.text.DocumentException{
		
		int cellByHeight = 20;
		
		//生成一个PDF文档
		com.itextpdf.text.Document document = new com.itextpdf.text.Document(com.itextpdf.text.PageSize.A4,30,30,20,20);
		
		
		//定义字节数组输出流对象，用于返回
		ByteArrayOutputStream os = new ByteArrayOutputStream();
		
		//获取pdf写对象
		com.itextpdf.text.pdf.PdfWriter.getInstance(document, os);
		//设置pdf文件的基本属性
		document.addTitle("");
		document.addAuthor("zfsoft");
		document.addSubject("zfsoft");
		document.addKeywords("zfsoft");
		document.addCreator("zfsoft");
		document.open();
		

		//定义字体
		com.itextpdf.text.pdf.BaseFont bfChinese = com.itextpdf.text.pdf.BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);   
		

		com.itextpdf.text.pdf.BaseFont bfChineseWHXW = com.itextpdf.text.pdf.BaseFont.createFont(ServletActionContext.getServletContext().getRealPath("/")+"/font/STXINWEI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);//华文新魏
		com.itextpdf.text.pdf.BaseFont bfChineseHT = com.itextpdf.text.pdf.BaseFont.createFont(ServletActionContext.getServletContext().getRealPath("/")+"/font/SIMHEI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);//黑体
		com.itextpdf.text.pdf.BaseFont bfChineseFS = com.itextpdf.text.pdf.BaseFont.createFont(ServletActionContext.getServletContext().getRealPath("/")+"/font/SIMFANG.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);//仿宋
		com.itextpdf.text.Font HeadFont = new com.itextpdf.text.Font(bfChinese,36,Font.NORMAL);
		com.itextpdf.text.Font HeadSchoolFont = new com.itextpdf.text.Font(bfChineseWHXW,36,Font.BOLD);
		com.itextpdf.text.Font cellFontHT = new com.itextpdf.text.Font(bfChineseHT, 16, Font.BOLD);
		com.itextpdf.text.Font cellFontFS = new com.itextpdf.text.Font(bfChineseFS, 14, Font.NORMAL);
		com.itextpdf.text.Font cellFont = new com.itextpdf.text.Font(bfChinese, 16, Font.NORMAL);
		com.itextpdf.text.Font smallCellFont = new com.itextpdf.text.Font(bfChinese, 12, Font.NORMAL);
