Oracle 12c JDBC方式連接PDB數據庫

1.配置監聽

這里假定CDB數據庫名為ORCL，PDB在CDB下面名稱為PDBORCL
listener.ora添加(#后面為注釋，不要添加進去)

SID_LIST_LISTENER =
    (SID_LIST =
        (SID_DESC = 
            (GLOBAL_DBNAME = ORCL)
            (SID_NAME = ORCL)  #這里是SID名
         )
        (SID_DESC = 
            (GLOBAL_DBNAME = PDBORCL)#這里是PDB數據庫名
            (SID_NAME = ORCL)  #這里是SID名
         )
     )

 tnsname.ora添加

PDBORCL=
    (DESCRIPTION =
        (ADDRESS_LIST =
            (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT =1521))
        )
        (CONNECT_DATA =
            (SERVICE_NAME = PDBORCL)  #這里是PDB數據庫名
        )
    )

 2.重啟監聽(需要管理員權限)

lsnrctl reload

 重啟監聽也可以用下面的代碼：
停止監聽

lsnrctl stop

 啟動監聽

lsnrctl start

 3.檢查JDBC代碼
注意:連接PDB時，1521端口號后面不是冒號:，而是斜線/
例如 

String url = "jdbc:oracle:thin:@//localhost:1521/pdborcl";
