ORA-12505：TNS监听器当前不知道连接描述符中给出的SID

我正在使用Oracle 12C作为我的数据库。我已经用Java编写了一个小型的JDBC连接程序，但是我面临着一个监听器的问题。ORA-12505：TNS监听器当前不知道连接描述符中给出的SID

import java.sql.Connection; 
import java.sql.DriverManager; 
import java.sql.PreparedStatement; 
import java.sql.ResultSet; 
import java.sql.SQLException; 

public class JdbcConnection { 
    public static void main(String[] args) throws SQLException,ClassNotFoundException { 
     String url = "jdbc:oracle:thin:@localhost:1521:orcl"; 
     String user = "system"; 
     String password = "password"; 
     Connection connection = null; 

     Class.forName("oracle.jdbc.driver.OracleDriver"); 
     connection = DriverManager.getConnection(url, user, password); 
     if(connection!=null){ 
      System.out.println("Success in connnection"); 
     } else { 
      System.out.println("failure in connection "); 
     } 
    } 
}

我得到以下异常：

C:\Users\Administrator\Desktop>java JdbcConnection 
Exception in thread "main" java.sql.SQLException: Listener refused the connectio 
n with the following error: 
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

你能告诉我们代码吗？ – Kryptos

您是否为计算机上的Oracle和侦听器启动了Windows服务？ –

是的，服务正在运行，我也重新启动了服务。 –

如果你知道你的Oracle数据库SID输出，然后用

jdbc:oracle:thin:@localhost:1521:orcl

otherwi参见下面的使用情况下，你有服务名称

jdbc:oracle:thin:@localhost:1521/orcl

此外，确保服务名称与名称ORCL应该是启动和运行。如果仍然无法工作，那么您需要重新启动机器，然后重试。

还在，无法正常工作？然后，尝试以下操作：

登录与用户SYSTEM通过以下SQLS运行注册LOCAL_LISTENER。

alter system set local_listener = '(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))' scope = both; 
alter system register;

如何检查Oracle SID和服务名称：

SELECT sys_context('USERENV', 'SID') FROM DUAL; -- It will return your oracle database SID 

SELECT sys_context('USERENV', 'SERVICE_NAME') FROM DUAL; -- It will return your oracle database service name

我已经尝试了上述两种格式仍然没有运气 –

然后，如我所说，重新启动您的机器，并尝试。 – Ravi

如果你想知道你的数据库的默认SID在sqlplus使用此查询：

SELECT sys_context('USERENV', 'SID') FROM DUAL;

在JDBC URL中使用此值而不是“orcl”。

你可以使用下面的URL吗？
注意不同之处，这是使用SERVICENAME而不是SID。

jdbc:oracle:thin:@localhost:1521/orclservice
