【问题讨论】：

检查这是否有帮助：***.com/questions/19334723/… 此外，您必须提供 Db 的完整路径，而不是使用 Db 名称，例如C:\\test\\Db\\WebsiteDatabase.mdb

那行不通。仍然得到同样的错误。

【参考方案1】：

检查

您已安装 MS Access 驱动程序

您使用的描述性字符串是正确的，“Microsoft Access Driver (.mdb)” 必须准确，检查 ODBC 控制面板应用程序中的驱动程序选项卡，例如我的是 (.mdb, *.accdb)

检查您没有将 64 位 JVM 与 32 位驱动程序混合使用，反之亦然。

【讨论】：

看起来像是 64 位 JVM。我如何获得 32 位？

是的，看起来只有 *.mdb 的第一个字符串适用于 32 位 JVM，而带有 *.mdb 和 *.accdb 的后者适用于 64 位驱动程序。请注意，与上面的示例不同，我的代码前面都有 *。

【参考方案2】：

如果您使用的是 32 位操作系统，那么我认为不会有这样的问题，但如果您使用的是 64 位操作系统，请按照以下步骤操作：

从here下载64位访问驱动。 运行安装程序，然后重新启动计算机。 转到开始 -> 控制面板 -> 管理工具 ->（数据源）ODBC -> 系统 DSN。 点击“添加”按钮。 选择“Microsoft Access 驱动程序 (*.mdb)” 提供任意数据源名称，然后点击“创建”。 选择你想要你的数据库的目录（注意：该目录应该和你的Java程序的源目录相同） 启动命令提示符以执行 64 位数据库连接。 复制C:\WINDOWS\SYSWOW64.exe到你电脑的运行对话框，然后他们开始编译和执行你的数据库程序。

【参考方案3】：

当我将笔记本电脑从 32 位 Windows XP 升级到 64 位 Windows 7 时，我在一个站点上遇到了这个问题。我通过创建 32 位应用程序池（应用程序池 > 高级设置 > 启用）克服了这个问题32 位应用程序 = True）并以这种方式运行我的网站。即使安装了 Microsoft Office，也不会为 64 位站点访问安装驱动程序。希望这可以帮助某人

【参考方案4】：

如果您使用的是 64 位操作系统，请按照以下步骤操作：

Download 64-bit access driver from http://www.microsoft.com/en-in/download/details.aspx?id=13255.

Run setup, then restart your computer.

If you are an application developer using ODBC to connect to Microsoft Office Access data, set the Connection String to “Driver=Microsoft Access Driver (*.mdb, *.accdb);DBQ=path to mdb/accdb file”

If you are an application developer using ODBC to connect to Microsoft Office Excel data, set the Connection String to “Driver=Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb);DBQ=path to xls/xlsx/xlsm/xlsb file”
