Java代码生成PDF（包括文字单选复选等按钮）

1. 概述

1. 开源框架支持

  • iText，生成PDF文档，还支持将XML、Html文件转化为PDF文件；
  • Apache PDFBox，生成、合并PDF文档；
  • docx4j，生成docx、pptx、xlsx文档，支持转换为PDF格式。

2.比较

  • iText开源协议为AGPL，而其他两个框架协议均为Apache License v2.0。
  • 使用PDFBox生成PDF就像画图似的，文字和图像根据页面坐标画上去的，需要根据字数手动换行。
  • docx4j用来生成docx文档，提供了将WORD文档转换为PDF文档的功能，并不能直接生成PDF文档。

2. 第一种 itext生成pdf

1. 第一步 准备软件，编辑模版

微博关注vposy，这上面都是Adobe Acrobat 的软件破解版
打开软件，文件-》创建表单-》添加表单域

image
image
注意，表单中的表单域名字需要与传出一致

2. 第二步 导包

    implementation 'com.itextpdf:itextpdf:5.5.13.3'

找不到可以去Maven仓库搜索 Maven仓库

3. 第三步 编写生成PDF工具类
