Question

这是连接代码

public class Connect {
    public ResultSet rs;
    Statement st;
    Connection con;
    PreparedStatement pStat;
    ResultSetMetaData rsm;

    public Connect() {
        // TODO Auto-generated constructor stub
        try {
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            File tempFile = new File("Project.mdb");
            con = DriverManager
                    .getConnection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=" + tempFile.getAbsolutePath());
            st = con.createStatement(1004, 1008);
            System.out.println("CONNECT");
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            System.out.println("Error Connection");
        }
    }

    public ResultSet executeQuery(String query) 
    {
        try {
            rs = st.executeQuery(query);
            rsm = rs.getMetaData();
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            System.out.println("Error Connection RS");
        }
        return rs;
    }

这是错误

尝试检查是否可以通过ODBC访问该数据库。
为{64}和32位系统在DSN中设置odbcad32。
然后作为JDBC连接字符串使用：jdbc：odbc：[CreatedDSN]。如果无法连接到64位版本的odbcad32中的Access，请确保它在32位版本的odbcad32中工作，并确保使用32位版本的Java。
