第一步：jar包依赖：

<dependency>
                <groupId>com.artofsolving</groupId>
                <artifactId>jodconverter</artifactId>
                <version>2.2.1</version>
            </dependency>
            
            <dependency>
                <groupId>com.github.livesense</groupId>
                <artifactId>jodconverter-core</artifactId>
                <version>1.0.5</version>
            </dependency>

第二步：功能代码

package com.digipower.ucas.openoffice.util;
    
    import java.io.File;
    import java.io.IOException;
    import org.artofsolving.jodconverter.OfficeDocumentConverter;
    import org.artofsolving.jodconverter.office.DefaultOfficeManagerConfiguration;
    import org.artofsolving.jodconverter.office.OfficeManager;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import com.digipower.ucas.common.exception.OpenOfficeException;
