① java.sql.SQLException: Listener refused the connection with the following error: ORA-12505, TNS:lis
找到这个目前下。
D:\oraclexe\app\oracle\proct\11.2.0\server\network\ADMIN
用记事本打开 listener.ora 文件；文件如下：
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oraclexe\app\oracle\proct\11.2.0\server)
(PROGRAM = extproc)
)
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = D:\oraclexe\app\oracle\proct\11.2.0\server)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 0HRTOR4KLCB9KTG)(PORT = 1521))
)
)
DEFAULT_SERVICE_LISTENER = (XE)
最后我在 eclipse 把SID 修改成最后那两位数：XE
代码如下：
public class testjdbc {
public static void main(String[] args) throws Exception {
Class.forName("oracle.jdbc.driver.OracleDriver");
String url = "jdbc:oracle:thin:@localhost:1521:xe";
String user = "XXX";
String password = "XXX";
Connection con=DriverManager.getConnection(url, user, password);
System.out.println(con);
}
}
最后运行结果：oracle.jdbc.driver.T4CConnection@1813fac
