java.net.SocketException: No route to host 异常原因
This exception is typically thrown by the Java networking classes when a connection attempt fails because there is no route to the specified host. This can happen for a variety of reasons, such as:
1. The destination host is not reachable from the local machine due to a network issue, such as a firewall blocking the connection or a misconfigured network interface.
2. The destination host is temporarily unavailable or offline.
3. The hostname or IP address used to connect to the remote host is incorrect or resolves to the wrong address.
To resolve this issue, you should first verify that the destination host is reachable from your local machine. You can try pinging the host or running a traceroute to diagnose any network issues. Additionally, you should ensure that the hostname or IP address used to connect to the remote host is correct and that any firewalls or network configurations are not blocking the connection.
