iText生成PDF

iText生成PDF【转载】

iText是著名的开放源码的站点sourceforge一个项目，是用于生成PDF文档的一个java类库。通过iText不仅可以生成PDF或rtf的文档，而且可以将XML、Html文件转化为PDF文件。 

　用iText生成PDF文档需要5个步骤： 

　① 建立com.itextpdf.text.Document对象的实例。 
    Document document = new Document();  
　② 建立一个书写器(Writer)与document对象关联，通过书写器(Writer)可以将文档写入到磁盘中。 
    PDFWriter.getInstance(document, new FileOutputStream("Helloworld.PDF"));  
　③ 打开文档。 
   document.open();  
　④ 向文档中添加内容。 
    document.add(new Paragraph("Hello World"));  
　⑤ 关闭文档。 
    document.close();  

　通过上面的5个步骤，就能产生一个Helloworld.PDF的文件，文件内容为"Hello World"。
