在浏览了几个教程和博客文章后,我尝试建立从 java 到 microsoft access 数据库的连接,但没有成功。我的系统规格是

win 7 [64 位] odbcad32.ese [64 位] 访问 2010 [64 位] jre6 [64 位]

我为建立连接编写的代码

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

我执行了以下任务

  1. USER DSN TAB ADD->Microsoft Access Driver (*.mdb, *.accdb) [file ACEODBC.dll] ->Finish

  2. 数据源名称:TestDriver;说明:access 2010 64位测试驱动;

  3. 数据库-> 选择 -> 浏览:C:\Users\ARIFAH\Desktop\sampleDb.mdb -> 确定

  4. 申请

  5. 好的

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?

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

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  

这似乎是驱动程序的 32 位和 64 位版本之间的区别。我能够使用该字符串与相同的环境进行连接。

(现在我只需要弄清楚我得到的“java.sql.SQLException:[Microsoft][ODBC Driver Manager] Invalid string or buffer length”错误是怎么回事......)
