前言
在java开发的过程中会遇到太多太多文档pdf导出，excle导出等业务场景，时隔三个月或半年来一次每一次遇到这样的业务场景对我都是非常痛苦的过程，本文旨在记录工具类使用方法和技术分享。
一、itextpdf是什么？
 itextpdf是一个开源的Java库，用于创建和操作PDF文档。使用itextpdf，您可以创建新的PDF文档或修改现有文档，添加文本和图像，创建表单等等。该库提供了广泛的功能，并经常用于企业级应用程序中根据用户输入动态生成复杂的PDF文档。它具有各种许可证选项，具体取决于您的用例，范围从AGPL到商业许可证。
itextpdf库提供了大量的方法和功能，以下是一些常用的方法：
创建PDF文档和页面：使用PdfWriter和Document对象可以创建一个新的PDF文档并添加页面。添加内容到PDF文档：使用Paragraph、Phrase和Chunk对象可以向PDF文档中添加文本内容。同时，也可以添加图片、表格等其它类型的内容。创建表格：使用PdfPTable对象可以创建表格，并向其中添加行和单元格。设置页眉页脚：使用HeaderFooter对象可以设置PDF文档的页眉和页脚，以及页码等信息。创建书签：使用PdfOutline对象可以创建PDF文档的书签，方便用户在浏览器中导航。导出PDF文档：使用PdfWriter对象可以将PDF文档导出为文件或流。
二、快速开始
1.废话不多说，效果先上一波
下列数据均为测试虚拟数据，不具有任何真实性
2.依赖引入
com.itextpdf
itextpdf
5.5.13
com.itextpdf
itext-asian
5.2.0
com.itextpdf.tool
xmlworker
5.5.11
3.模版加载
 rescources-templates-创建一个pdf模版，如果没有定制内容，直接为空白即可
