无法建立JDBC连接：预言：瘦：@localhost：1521：ORCL使用oracle.jdbc.OracleDriver（IO异常：网络适配器不能建立连接）

Answer 1

尝试以下任何一种解决方案

1. If the network port is not open, or it is blocked by a firewall, you can try TELNET.
2. If DB listener is not running or is binding to a different network interface, you can try either TELNET or else use Oracle client tools to connect.
3. If again the problem persists, you may please start the listener through command prompt (lsnrctl start)
