1. 需求描述
- 从指定位置读取一个 word 模板
- 获取业务数据并写入该 word 模板，生成新的 word 文档
- 将新生成的 word 文档转换为 pdf 格式
- 对 pdf 文档添加水印
2. 效果预览
- word 模板
- 带水印的 pdf 文档
3. 实现思路
- word 模板数据写入：使用
poi-tl库实现 - word 转 pdf 格式：
aspose-words库实现 - pdf 增加水印：
aspose-pdf库实现
4. 实现过程
4.1 依赖库准备
poi-tl 可以使用 maven 直接从中央仓库下载，但是 aspose 无法下载，需要从网上下载 jar 包并导入本地仓库
-
poi-tl
<dependency><groupId>com.deepoove</groupId><artifactId>poi-tl</artifactId><version>1.12.1</version></dependency> -
aspose-word
将 jar 包导入本地仓库mvn install:install-file \-DgroupId="com.aspose" \-DartifactId="aspose-words" \-Dversion="15.8.0" \-Dpackaging="jar" \-Dfile="aspose-words-15.8.0-jdk16.jar"项目中添加依赖
<dependency><groupId>com.aspose</groupId><artifactId>aspose-words</artifactId><version>15.8.0</version></dependency> -
aspose-pdf
将 jar 包导入本地仓库mvn install:install-file \-DgroupId="com.aspose" \-DartifactId="aspose-pdf" \-Dversion="17.8" \-Dpackaging="jar" \-Dfile="aspose.pdf-17.8.jar"项目中添加依赖
<dependency><groupId>com.aspose</groupId><artifactId>aspose-pdf</artifactId><version>17.8</version></dependency> -
license.xml
由于aspose库分为免费版和收费版，免费版导出的文档带有试用水印，所以需要添加license.xml，版权关系不在文章中写出，有需要的可以下载文章顶部链接的完整源码包。
