使用PDFBox动态创建多页面文档 [英] Create mutli-page document dynamically using PDFBox

问题描述

我正在尝试从Java ResultSet创建PDF报告。如果报告只有一页，我在这里没问题。问题来自报告可能长达一到十页的事实。现在，我有这个来创建一个单页文档：

I am attempting to create a PDF report from a Java ResultSet. If the report was only one page, I would have no problem here. The issue comes from the fact that the report could be anywhere from one to ten pages long. Right now, I have this to create a single-page document:

PDDocument document = new PDDocument();
PDPage page = new PDPage(PDPage.PAGE_SIZE_LETTER);
document.addPage(page);
PDPageContentStream content = new PDPageContentStream(document,page);

所以我的问题是，如何根据需要动态创建页面。是否有一个面向对象的答案盯着我，我只是看不到它？

So my question is, how do I create pages dynamically as they are needed. Is there an object-oriented answer staring me in the face and I just cannot see it?

推荐答案

正如我所料，答案我正好盯着我，我只需要有人为我指出。

As I expected, the answer was staring me right in the face, I just needed someone to point it out for me.

PDDocument document = new PDDocument();
PDPage page = new PDPage(PDPage.PAGE_SIZE_LETTER);
document.addPage(page);
PDPageContentStream content = new PDPageContentStream(document,page);

//generate data for first page

content.close();

//if number of results exceeds what can fit on the first page
page = new PDPage(PDPage.PAGE_SIZE_LETTER);
document.addPage(page);
content = new PDPageContentStream(document,page);

//generate data for second page

content.close();
