连接失败, 错误报告:
user = store
url = jdbc:oracle:thin:@orclpdb
错误消息 = io 错误: unknown host specified
碰到这个问题的童靴们，正解如下：
首先在 oracle enterprise manager database express 12c中查看容器名是
然后在 $home$\product\12.2.0\dbhome_1\network\admin\tnsnames.ora中增加
orclpdb =
(description =
(address = (protocol = tcp)(host = localhost)(port = 1521))
(connect_data =
(server = dedicated)
(service_name = orclpdb)
)
)
这样，在登录的时候写@orclpdb就可以解析为本地host了，之前出现登录不了也就是无法解析到本地localhost
