The The Network Adapter could not establish the connection network adapter could not create a connection

As a beginner, this problem has made me look for it many times. Every time I restart the computer, I can get the connection normally. After a while, I don't know what I have done, I will report an error again, and when I use pl/sql, I will log in and the user will not log in for half a day.

The configuration file is as follows:

The statement to get the connection is as follows

Public static Connection getConnection () {

String className = SmbmsProperties.getInstance () .getValue ("jdbc.class")

String user = SmbmsProperties.getInstance () .getValue ("jdbc.user")

String password= SmbmsProperties.getInstance () .getValue (jdbc.password)

String url = SmbmsProperties.getInstance () .getValue ("jdbc.url")

Connection connection=null

Try {

Class.forName (className); / / load driver

Connection=DriverManager.getConnection (url, user, password); / / obtain database connection

} catch (Exception e) {

E.printStackTrace ()

}

Return connection

}

The reason why I have this problem is that I turned on sharing wifi on my computer, which caused my mistake.

It should be a network conflict. Do not turn on the shared wifi after reboot and ok it.
