Methods to solve Java network connection interruption timeout error exception (ConnectionInterruptedTimeoutErrorExceotion)

Abstract: In Java programming, we often encounter network connection interruption timeout error exception ( ConnectionInterruptedTimeoutErrorExceotion). This kind of anomaly is very common in network communication and may cause some trouble to our program. This article describes several ways to solve this problem and provides relevant code examples.

1. Check whether the network connection is normal

When a network connection interruption timeout error occurs, first check whether the network connection is normal. You can use the ping command or test via Socket in Java code. The following is an example of checking whether the network connection is normal through Java code:

import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;

public class NetworkUtils {
    
    public static boolean isNetworkConnected() {
        try {
            InetAddress ip = InetAddress.getByName("www.google.com");
            Socket socket = new Socket(ip, 80);
            return true;
        } catch (IOException e) {
            return false;
        }
    }
}

In the above example, we determine whether the network is normal by trying to establish a Socket connection with the Google server. If the connection is successful, it means the network connection is normal; if the connection fails, it means the network connection is interrupted or times out.

2. Set the connection timeout period

If the network connection is normal, but a connection interruption timeout error occurs during the request, it is likely that the connection timeout setting is unreasonable. We can solve this problem by setting the connection timeout. The following is an example:

import java.net.URL;
import java.net.HttpURLConnection;

public class ConnectionUtils {
    
    public static void main(String[] args) {
        try {
            URL url = new URL("http://www.example.com");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setConnectTimeout(5000); // 设置连接超时时间为5秒
            connection.setReadTimeout(5000); // 设置读取超时时间为5秒
            connection.connect();
            // do something with the connection
            connection.disconnect();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

In the above example, we set the connection timeout and read timeout to 5 by setting the setConnectTimeout method and the setReadTimeout method. Second.

3. Retry mechanism

Another way to solve the problem of network connection interruption timeout error is through the retry mechanism. When a connection interruption timeout error occurs, we can try to reconnect a certain number of times until the connection is successful or the maximum number of retries is reached. Here is an example:

import java.net.URL;
import java.net.HttpURLConnection;

public class RetryUtils {
    
    private static final int MAX_RETRY_TIMES = 3;
    
    public static void main(String[] args) {
        int retryTimes = 0;
        boolean success = false;
        
        while (retryTimes < MAX_RETRY_TIMES && !success) {
            try {
                URL url = new URL("http://www.example.com");
                HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                // do something with the connection
                connection.disconnect();
                success = true;
            } catch (Exception e) {
                e.printStackTrace();
                retryTimes++;
            }
        }
        
        if (!success) {
            System.out.println("Failed to establish connection after " + MAX_RETRY_TIMES + " retries.");
        }
    }
}

In the above example, we try to re-establish the connection through a loop and end when the connection is successful or the maximum number of retries is reached.

Conclusion:

In Java network programming, it is very common to encounter network connection interruption timeout error exception. We can solve this problem by checking whether the network connection is normal, setting the connection timeout and retry mechanism, etc. We remind everyone to pay attention to exception handling and reasonable timeout settings when performing network communications to avoid the occurrence of network connection interruption timeout errors.
