刚装了个oracle11g，然后尝试连接，没想到连接失败，错误代码如下：
Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
The Connection descriptor used by the client was:
localhost:1521:oracle
程序中方法如下：
public static Connection getConnection() {
Connection conn = null;
String driver ="oracle.jdbc.driver.OracleDriver";
String url = "jdbc:oracle:thin:@localhost:1521:oracle";
String uName = "scott";
String pswd = "tiger";
try {
Class.forName(driver);
conn = DriverManager.getConnection(url, uName, pswd);
} catch (ClassNotFoundException e) {
System.out.println("类加载错误"+e.getMessage());
} catch (SQLException e) {
System.out.println("连接错误"+e.getMessage());
e.printStackTrace();
}
return conn;
}
请问下是哪里出了问题啊，急
