安装好了之后可以通过这个路径找到一个文本文件:
oracle\product\10.2.0\db_1\NETWORK\ADMIN\listener.ora 还一个在同路径下的tnsnames.ora文件,这两个文本中的一些信息要一样的。
比如下面的:

listener.ora
# listener.ora Network Configuration File: F:\oracle\product\10.2.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = F:\oracle\product\10.2.0\db_1)
      (PROGRAM = extproc)
    )
     (SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = F:\oracle\product\10.2.0\db_1) 
      (SID_NAME = orcl)
    ) 
 
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    )
  )




tnsnames.ora
# tnsnames.ora Network Configuration File: F:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

最终发现原因是因为本人没有新建数据库与网络服务名相对应。
