在网上查找修改监听文件,修改如下：

# listener.ora Network Configuration File: D:\app\xiaoyu\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

      (ORACLE_HOME = D:\app\xiaoyu\product\11.2.0\dbhome_1)
      (PROGRAM = ORCL)

    )
  )

ADR_BASE_LISTENER = D:\app\xiaoyu

请老鸟帮帮忙啊 Oracle Java 数据库网络编程
[解决办法]
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.103)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
  )

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
      (SID_NAME = orcl)
    )
  )

# tnsnames.ora Network Configuration File: /oracle/product/10.2.0/db_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

ORCL =
  (DESCRIPTION =
    (ADDRESS_LIST=
       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.103)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

试试这两个，改成ip地址，别用localhost
关掉防火墙
重新启动监听
