  • java使用jacob将office文档转换为PDF格式

    jacob 包下载地址: http://sourceforge.net/projects/jacob-project/

    下载后,将jacob 与 jacob-1.19-x64.dll放到安装jdk目录中

    jacob.jar  放入到 jdk/jre/lib/ext中

    jacob-1.19-x64.dll放入到 jdk/jre/bin中

    实现代码如下

    package com.ypr.modules.op.utils;
    
    import java.io.File;
    
    import com.jacob.activeX.ActiveXComponent;
    import com.jacob.com.ComFailException;
    import com.jacob.com.ComThread;
    import com.jacob.com.Dispatch;
    import com.jacob.com.Variant;
