推荐答案

DriverManager尝试获取具有无效URL的连接时，将引发此错误.确保您的URL有效. 结帐事项:

DriverManager throws this error when it tries to get a connection with invalid URL. Make sure your URL is valid. Things to checkout:

1. 端口:Oracle db在1521上运行.(注意:不要将自己与oracle的webport混淆，它可以是URL 1158中的任何其他端口).
2. 数据库名称:从Oracle Web UI获取数据库名称:(home-> adminIstration-> aboutdatabase-> settings)
3. URL格式:"jdbc:oracle:thin:@localhost:1521:YourDbName"
