SpringBoot整合openoffice实现word文档的读取和导入及报错处理

先安装openoffice4

Linux系统安装参考：https://www.cnblogs.com/pxblog/p/11622969.html

Windows系统安装参考：https://www.cnblogs.com/pxblog/p/14346148.html

引入jar包

密码:1cjp

如果是pom文件的话

<dependency>
            <groupId>local</groupId>
            <artifactId>jodconverter</artifactId>
            <version>2.2.2</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/webapp/WEB-INF/lib/jodconverter-2.2.2.jar
            </systemPath>
        </dependency>
        <dependency>
            <groupId>local</groupId>
            <artifactId>jodconverter-cli</artifactId>
            <version>2.2.2</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/webapp/WEB-INF/lib/jodconverter-cli-2.2.2.jar
            </systemPath>
        </dependency>
        <dependency>
            <groupId>local</groupId>
            <artifactId>jodconverter-core</artifactId>
            <version>3.0-beta-4</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/webapp/WEB-INF/lib/jodconverter-core-3.0-beta-4.jar
            </systemPath>
        </dependency>

然后把jar包放到项目/webapp/WEB-INF/lib/下，这位置可以根据自己的来，然后pom文件路径也做相应修改即可

日志注解用到了

如果idea启动报错了

Description:
