java解析PDF、WORD获取其中的表格以及文本内容

近期因工作需要需要解析PDF，需要把PDF中的文本和表格分离，最终要实现的目标是PDF中的文本内容放一块，表格内容放一块，以list的形式存储。解析PDF的技术有很多，经过多次尝试发现使用AdobeAcrobat可以实现表格和文本分离。

注意事项：

1、下载AdobeAcrobat进行安装

2、使用时如果有报jacob的错把jacob-1.18-M1-x64.dll、jacob-1.18-M1-x86.dll这两个文件放到Java>jdk1.8.0_271>bin目录下

3、引入依赖：

     <dependency><groupId>jacob</groupId><artifactId>jacob</artifactId><version>1.1.8</version></dependency> <dependency><groupId>org.jsoup</groupId><artifactId>jsoup</artifactId><version>1.17.2</version></dependency>

工具类如下（内附PDF的文件转换方法以及获取纯文本和纯表格的测试方法）：
