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"。
