public static Connection getCon(){
Connection conn = null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:XDF","jean","jean");
System.out.println(conn);
} catch (Exception e) {
e.printStackTrace();
}
return conn;
}

getCon();
}
}请教高手，急，在线等！
