java 根据PDF模板生成PDF文件并导出
1.准备操作的maven包
<dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.5.1</version>
</dependency>
<dependency><groupId>com.itextpdf</groupId><artifactId>itext-asian</artifactId><version>5.2.0</version>
</dependency>
2.准备好你需要操作的PDF模板
3.准备好Adobe Acrobat Distiller DC 工具
4.使用Adobe Acrobat 打开你准备好的pdf模板，如图：
打开工具栏，找到准备表单
打开后，你就可以对你需要赋值的PDF表单进行字段的编辑，如下图：
5.使用Java 读取pdf文件

这样对pdf文件赋值就成功了，新手小白欢迎指正
