Question

经过几个教程和博客文章后，我试图建立从java到微软访问数据库的连接失败。我的系统规格是

win 7 [64 bit] odbcad32.ese [64 bit] access 2010 [64 bit] jre6 [64 比特]

我为建立连接而编写的代码：

        public Connection makeConn() throws ClassNotFoundException, SQLException
        {
           Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
           conn = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=C:\\Users\\ARIFAH\\Desktop\\sampleDb.mdb");

           return conn;
        }

数据源中的

[odbc] --- [位于路径％windir％\ system32 \ odbcad32.exe ]

我执行了以下任务

USER DSN TAB ADD-＆gt; Microsoft Access驱动程序（* .mdb，* .accdb）[文件ACEODBC.dll] - ＆gt;完成
数据源名称：TestDriver; 描述：访问2010 64位的测试驱动程序;
数据库 - ＆gt;选择 - ＆gt;浏览：C：\ Users \ ARIFAH \ Desktop \ sampleDb.mdb - ＆gt;确定
应用
确定

现在当我尝试运行我的应用程序时，这是我得到的错误，

有人可以帮忙吗？

Answer 1

您是否尝试将连接字符串更改为：

jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=C:\\Users\\ARIFAH\\Desktop\\sampleDb.mdb

这似乎是32位和64位版本驱动程序之间的差异。我可以使用相同的环境使用该字符串进行连接。

（现在我只需要弄清楚“java.sql.SQLException：[Microsoft] [ODBC驱动程序管理器]无效的字符串或缓冲区长度”正在发生的事情“我得到的错误......）

Answer 2

根据此博客，您要么必须运行32位版本的Java，要么使用64位版本的办公室驱动程序：

建立从java到访问2010 64bit的连接
