近来收到一个需求, 制作 PDF 制作发票.
类似于制作这样的发票
技术选型我选择java
在网上寻找了一些操作PDF的框架决定用iText制作, 因为它比较活跃, 而且后期做签章和插入图片二维码都有着现成的接口.
大体想了下难点都在什么地方, 插入图片,商品太多时候的分页问题,数字签章........
于是我就开始尝试着使用 iText的新建操作pdf,
新建maven工程
加入依赖
<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok -->

起初准备自己画这个table, 后来花了几个都很丑于是参考网上发可以先制作模板,预设表单值再往里面填入表单数据.
具体可以通过Adobe Acrobat Pro去制作
制作好的模板
