数据库连接包括连接池。很有用的资料

//connect with the JDBC Thin Driver
import java.sql.*;
class dbAccess {
  public static void main (String args []) throws SQLException
  {
        DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());

        Connection conn = DriverManager.getConnection
             ("jdbc:oracle:thin:@hostname:1526:orcl", "scott", "tiger");
                             // @machineName:port:SID,   userid,  password

        Statement stmt = conn.createStatement();
        ResultSet rset = stmt.executeQuery("select BANNER from SYS.V_$VERSION");
        while (rset.next())
              System.out.println (rset.getString(1));   // Print col 1
        stmt.close();
  }
}
