Question

我是java的新手，我想了解如何登录java应用程序，我已经使以下ConnectAccess类与Microsoft Access连接

import java.sql.*;
public class ConnectAccess {
public static Connection con = null;
public static Statement stmt = null;
//public static String DBase =  "jdbc:odbc:Driver={Microsoft Access Driver(*.mdb)};DBQ=1401087265db.mdb;";
public static String DBase =  "jdbc:odbc:datasource_access";
public static ResultSet rs = null;

public ConnectAccess() {
    try {
        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        try {
            Connection conn = DriverManager.getConnection(DBase, "", "");
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    } catch (ClassNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }       
}

public ResultSet getData(String Query) //provide quickfix eclipse
{       
    try {               
        stmt.execute(Query);            
        rs=stmt.getResultSet();         
        if(rs!=null && rs.next())
        {
            return rs;
        }
        else
        {
            return null;
        }
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return null;    
}

public void deleteData(String primarykey,String primarykeyvalue, String table)
{
    try {
        stmt.executeUpdate("Delete from "+table+"where "+primarykey+" = '"+primarykeyvalue+"'");
        stmt.close();
        con.close();
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

public static void main(String[] args) {
    // TODO Auto-generated method stub

}

}

以及我Login按钮中的代码

            ConnectAccess ca = new ConnectAccess();
            ResultSet resultnya = ca.getData("Select * from MsUser where Username = '"+inusernamenya+"' and password = '"+inpassword+"'");
            try {
                if(resultnya.next())
                {
                    cmd.printSuccess(inusernamenya+" dan "+inpassword+" berhasil login", form_name);                            
                    Cl_Main mainform = new Cl_Main();                           
                }
                else
                {
                    cmd.printError("Invalid username or password !", form_name);
                }
            } catch (SQLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

我不知道java是否无法找到我的数据库位置，或者我的java构建路径是否有问题，

我该如何解决这个问题？

和eclipse给我看了一个新标签。。。

Answer 1

我认为DBase值是错误的。您可以尝试DBase = "jdbc:odbc:xxxxx";其中xxxxxx是使用标准Windows ODBC数据源管理员设置的ODBC数据源的名称。在那里你可以说你想要一个MS Access驱动程序等。

例如，请查看此处：http://www.interfaceware.com/manual/setting_up_odbc_datasource.html

请注意，Oracle不支持您正在使用的JDBC-ODBC桥，并且将被放弃。见https://docs.oracle.com/javase/7/docs/technotes/guides/jdbc/bridge.html
