ssm根据pdf模板导出pdf

一、使用word设计pdf模板，并另存为pdf格式的文件。

二、使用Adobe Acrobat DC工具，打开pdf文件，工具中选择准备表单并打开

三、在文件中设置域名称，如下图

四、下面是正式的操作

pom依赖

<!-- 	生成PDF相关	iText，必须引入jar包 -->
		<dependency>
		  <groupId>com.itextpdf</groupId>
		  <artifactId>itextpdf</artifactId>
		  <version>5.5.12</version>
		</dependency>
		
		
		<!-- 	生成PDF相关	输出中文，还要引入下面itext-asian.jar包： -->
		<dependency>
		  <groupId>org.bouncycastle.bcprov-jdk15on.1.57.org.bouncycastle</groupId>
		  <artifactId>bcprov-jdk15on</artifactId>
