java拼接word文档

#java拼接word文档
说到java操作word 文档，其实网上都已经讲的很多了。我就不再一一赘述了，这里我只记录下使用 docx4j 拼接word文档，使用jacob 调用word 进程生成或者更新docx目录的基本操作。

引入依赖

<dependency><groupId>org.docx4j</groupId><artifactId>docx4j-JAXB-Internal</artifactId><version>8.0.0</version>
</dependency>
<!-- 排除依赖的操作根据自己具体环境选择 -->
<dependency><groupId>org.docx4j</groupId><artifactId>docx4j-export-fo</artifactId><version>8.0.0</version><exclusions><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></exclusion></exclusions>
</dependency><!-- https://mvnrepository.com/artifact/net.sf.jacob-project/jacob -->
<dependency><groupId>net.sf.jacob-project</groupId><artifactId>jacob</artifactId><version>1.19</version>
</dependency>
