如何使用Jacob将Excel文件另存为(Java)

Question

我正在尝试另存为excel文件，但它给出一个错误:无法将名称映射到调度I: FileSaveAs。

private ActiveXComponent objExcel = new ActiveXComponent("Excel.Application");
excelObject = objExcel.getObject();
Dispatch.put(excelObject, "Visible", new Variant(false));
workbook = objExcel.getProperty("Workbooks").toDispatch();
workbook = Dispatch.call(workbook, "Open", filename).toDispatch();
Dispatch oExcel = Dispatch.call(objExcel, "Workbooks").getDispatch();
Dispatch.call(workbook, "FileSaveAs", filename, new Variant(51));

变量的参数取自：http://msdn.microsoft.com/en-us/library/bb241279(v=office.12).aspx

有人能告诉我代码中的问题在哪里吗？谢谢

我不确定我是否使用了正确的方法，但它是有效的

public Boolean savesAS(String path, String nameFile){

    ComThread.InitSTA();

    ActiveXComponent excel = new ActiveXComponent("Excel.Application");
    excel.setProperty("Visible", new Variant(true));
    Object workbooks = excel.getProperty("Workbooks").toDispatch();
    Object workbook;

    try {            
        workbook = Dispatch.call((Dispatch)workbooks, "Open", path).toDispatch();           
    } catch (Exception e) {
        showMessageDialog(null,"Unable to open " + path);
        return false;
    }

    try {
        //here you can modify the value of "new Variant(int)" with other number
        Dispatch.call((Dispatch)workbook, "SaveAs", nameFile ,new Variant(2)); 
    } catch (Exception e) {
         showMessageDialog(null,"Unable to convert " + path);
        return false;
    }

    Dispatch.call((Dispatch)workbook, "Close", new Variant(false));

    excel.invoke("Quit", new Variant[0]);
    excel.safeRelease();
    ComThread.Release();

    return true;
}

如错误所述，它无法找到方法"FileSaveAs“。我试图在Google/文档中查找它，但没有找到(可能它存在，但我找不到它)。相反，我找到了SaveAs。所以试着使用它，看看会发生什么。

是的，你是对的，它确实适用于"Saveas“。实际上"FileSaveAs“适用于word文档，所以我想尝试它与Excel和Powerpoint，但它不起作用…

要将excel工作簿另存为，请执行以下代码：

 Dispatch.call(workbook, "SaveAs", filename, new Variant(1));
