最近在做SpringBoot+Vue的项目，需要将委托单商品的数据导出为PDF文档。Java的PDF操作第三方工具类用的最多的应该是itextpdf了吧，当然以前也用过icepdf这种小众的。那现在就来看看用itextpdf怎么做，还是很简单的。
首先前端页面如下，可以导出箱单和发票两种格式的PDF文件：
一、引入itextpdf依赖
<!--PDF导出-->
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itextpdf</artifactId>
<version>5.4.3</version>
</dependency>
只需要这一个包就可以了。网上其他教程引了一大堆包，完全没必要。
二、主要业务代码
导出发票

主要思路是先根据委托单的流水号，查询出其下的商品数据，然后写入生成的PDF文件中。再读取生成的PDF文件，根据关键字“Bill To”的坐标插入印章，最后转为字节流输出给前端下载。

PdfPCell cell = new PdfPCell(); //创建单元格

3. 注意：箱单的话需要纵向合并单元格，而itextpdf的纵向合并简直是残废，这里需要单独处理下：
/**

* @param table
* @param apply
* @param headFont
* @param childFont
* @return void
* @author ZHANGCHAO
* @date 2021/1/28 10:53

三、测试
1. 导出的发票如下：
2. 导出的箱单如下：
总的来说用itextpdf导出PDF还是很简单的，需要其他功能可以自己研究。
以上！
