Java实现doc转docx

jacob这个包可以实现此功能

jacob-1.19-x86.dll  
jacob-1.19-x86.dll
这两个文件放到system32下或者java的jre的bin目录下

public static String convertDocx(String filePath,String descPath) {
    ComThread.InitMTA();
    ActiveXcomponent app = new ActiveXcomponent("Word.Application");
    try{
    app.setProperty("Visible",new Variant(false));
    //实例化模板
    Dispatch document = app.getProperty("Documents").toDispatch();
    //打开document进行零存在操作
    Dispatch doc = Dispatch.invoke(document,"Open",Dispatch.Method,new Object[]{filePath,new Variant(true)},new int[1]).toDispatch();
    Dispatch.invoke(doc,"SaveAs",Dispatch.Method,new Object[]{descPath,new Variant(12)},new int[1]);
    Dispatch.call(doc,"Close",new Variant(false));
    return descPath;
    }catch(Exception e){
    throw new Exception();
    }finally{
    app.invoke("Quit",new Variant[]{});
    ComThread.Release();
    }
 }
