问题描述

有一些问题，但不是最近，技术必须从那时开始。

There were questions on that but not recently and technology must have gone ahead since then.

要求：

• 根据预定义模板生成pdf文档（我可以使用） pdf表格或xsl-fo）


• 能够填写文本数据


• 能够填充图形数据（生成条形码）


• 能够在生产环境中更改pdf模板而无需修补（重新编译）


• 生成要保存在数据库中的pdf文件（作为blob）和/或打印


• 开源/免费

• generating pdf documents based on predefined template (I can use either pdf forms or xsl-fo)
• being able to fill textual data
• being able to fill graphical data (generated bar codes)
• being able to alter pdf template in production environment without patching (recompiling)
• generating pdf file to be saved in the database (as blob) and/or printed
• open source/free

假设的选项是iText，PDFBox，FOP，还有其他？什么是基于上述要求的建议？

The options assumed are iText, PDFBox, FOP, anything else? What are recommendations based on the requirements above?

推荐答案

1. iText;如今iText是一个商业图书馆，最新版本不再免费


2. FOP;我和FOP一起工作了很多。它是相当资源密集型的（Java> XML> XSLT> PDF），复杂的PDF变成了一场噩梦（可能导致XSLT带有20k + LoC）


3. PDFBox;它似乎是最好的选择，虽然我没有在大项目中使用它


4. 没有检查飞碟

1. iText; nowadays iText is a commercial library, the latest version is not for free anymore
2. FOP; I worked a lot with FOP. It's fairly resource intensive (Java > XML > XSLT > PDF) and complex PDFs become a nightmare ( may result in XSLTs with 20k+ LoC)
3. PDFBox; it seems to be the best alternative although I did not work with it in large projects
4. Did not check Flying Saucer yet

总而言之，我会试试PDFBox。根据您的条形码要求，您可能需要将条形码（字体）内嵌到PDF中或将字体分发给您的客户 - 处理这些问题。

To conclude, I'd give PDFBox a try. Depending on your bar code requirements you may need to inline your barcode (font) into the PDF or distribute the font to your clients - take care of those issues.
