Java Oracle localhost connection error (ORA-12505)
当我尝试连接到 Oracle 10g Express Edition 时，出现错误:
java.sql.SQLException: 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:xe
我的示例代码:
Class.forName("oracle.jdbc.OracleDriver");
Connection connection = null;
connection = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe", "mk119", "mk119");
Statement stmt = connection.createStatement();
在数据库中:
SQL> connect mk119
Enter password:
Connected.
SQL> ed
Wrote file afiedt.buf
1* select sys_context('userenv', 'instance_name') from dual
SQL> /
SYS_CONTEXT('USERENV','INSTANCE_NAME')
----------------------------------------------------------------------
xe
SQL>
请帮我解决这个问题。
