在从有用的用户那里得到建议后，我对代码进行了一些更改。
我缺少什么来加载该驱动程序？
建议我购买Jackcess，并将其包含在我的图书馆中。我正在使用Java 8
我没有过去
Connection conn = DriverManager.getConnection(database, "", "");
在它抛出一堆异常之前。
import java.sql.*;
import javax.swing.JOptionPane;
import java.sql.DriverManager;
private void SubmitActionPerformed(java.awt.event.ActionEvent evt) {
try {
String database = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=db1.mdb;";
Connection conn = DriverManager.getConnection(database, "", "");
//String driver = "sun.jdbc.odbc.JdbcOdbcDriver";
//Class.forName(driver);
// String db = "jdbc:odbc:db1";
//con = DriverManager.getConnection(db);
st = conn.createStatement();
System.out.println("it actually ready this set of code!");
String un = UserName.getText().trim();
String pw = Password.getText().trim();
String sql = "select user,pass from Table2 where user='"+un+"'and pass='"+pw+"'";
rs=st.executeQuery(sql);
int count = 0;
while(rs.next()){
count = count+1;
}
if (count==1){
JOptionPane.showMessageDialog(null,"User, Found Access Granted!");
}
else if (count>1){
JOptionPane.showMessageDialog(null,"Duplicate User, Access Denied!");
}
else {
JOptionPane.showMessageDialog(null, "user doesn't exsist. ");
}
} catch (Exception ex){
System.out.println("exception 2, " );
ex.printStackTrace();
}
// TODO add your handling code here:
}
这些是我得到的异常错误：
exception 2,
java.sql.SQLException: No suitable driver found for jdbc:odbc:Driver= {Microsoft Access Driver (*.mdb)};DBQ=db1.mdb;

最佳答案
您正在尝试使用JDBC访问数据库。根据Jackcess FAQ，Jackcess驱动程序不支持JDBC：
Jackcess是否为Microsoft Access数据库提供JDBC驱动程序？
很不幸的是，不行。 Jackcess API是可用于与Access数据库进行交互的功能的直接实现。目前，Jackcess库没有实现JDBC API的实现。尽管此库将为JDBC驱动程序奠定良好的基础，但实现JDBC API的当前项目范围之外。曾有几次尝试使用Jackcess为Access数据库构建JDBC驱动程序，但是大多数项目在变得不活跃之前还没有取得很大进展。但是，UCanAccess project是一个当前活动的开源项目，它提供一个基于Jackcess的JDBC驱动程序。
here提供了有关如何使用Jackcess专有DB API的更多信息。
