Methods to solve Java network connection interruption timeout exception (ConnectionInterruptedTimeoutExceotion)

In Java network programming, timeout exceptions caused by network connection interruption are often encountered. This anomaly may occur in various network environments, such as connection interruptions caused by network delays, network instability, etc. This article explains how to resolve connection interruption timeout exceptions and provides some code examples.

1. Set the connection timeout period

Java provides a method to set the connection timeout period. You can set a timeout period when establishing a connection. When the connection times out, the connection will be thrown. Interrupt timeout exception. We can use the following code snippet to set the timeout:

import java.net.*;
import java.io.*;

public class ConnectionTimeoutExample {
    public static void main(String[] args) throws IOException {
        URL url = new URL("http://www.example.com");
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setConnectTimeout(5000); // 设置超时时间为5秒

        try {
            conn.connect();
        } catch (ConnectException e) {
            System.out.println("连接超时异常：" + e.getMessage());
        } finally {
            conn.disconnect();
        }
    }
}

In the above code, we create a URL object through the URL class and convert it to HttpURLConnectionObject. Then, we use the setConnectTimeout() method to set the connection timeout to 5 seconds. When calling the connect() method to establish a connection, if the connection times out, a ConnectException exception will be thrown.

2. Set the read timeout period

In addition to setting the connection timeout period, we can also set the read timeout period. Sometimes, even if the connection is successfully established, a timeout exception may be encountered when reading data. We can use the following code snippet to set the read timeout:

import java.net.*;
import java.io.*;

public class ReadTimeoutExample {
    public static void main(String[] args) throws IOException {
        URL url = new URL("http://www.example.com");
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setConnectTimeout(5000); // 设置连接超时时间为5秒
        conn.setReadTimeout(5000); // 设置读取超时时间为5秒

        try {
            conn.connect();
            // 读取数据的代码
        } catch (SocketTimeoutException e) {
            System.out.println("读取超时异常：" + e.getMessage());
        } finally {
            conn.disconnect();
        }
    }
}

In the above code, we have created a URL object through the URL class and converted it to HttpURLConnection object. Then, we set the connection timeout to 5 seconds using the setConnectTimeout() method, and set the read timeout to 5 seconds using the setReadTimeout() method.

3. Use the retry mechanism

In addition to setting the timeout, we can also use the retry mechanism to solve the problem of connection interruption. When a connection interruption timeout exception occurs, we can try to re-establish the connection until the connection is successful or the maximum number of retries is reached.

The following is a code example using the retry mechanism:

import java.net.*;
import java.io.*;

public class RetryExample {
    public static void main(String[] args) throws IOException {
        String urlString = "http://www.example.com";
        int maxRetryTimes = 3;

        URL url = new URL(urlString);
        HttpURLConnection conn = null;

        for (int i = 0; i < maxRetryTimes; i++) {
            try {
                conn = (HttpURLConnection) url.openConnection();
                conn.setConnectTimeout(5000); // 设置连接超时时间为5秒
                conn.setReadTimeout(5000); // 设置读取超时时间为5秒

                conn.connect();
                // 读取数据的代码
                break; // 连接成功，跳出重试循环
            } catch (IOException e) {
                System.out.println("连接中断异常：" + e.getMessage());
            } finally {
                if (conn != null) {
                    conn.disconnect();
                }
            }
        }
    }
}

In the above code, we define a maximum number of retries maxRetryTimes, for each connection If interrupted, we will all try again.

Summary:

This article introduces several methods to solve Java network connection interruption timeout exception, including setting the connection timeout, setting the read timeout and using the retry mechanism. According to the specific needs and circumstances, we can choose the appropriate method to solve the connection interruption timeout exception and ensure the stability and reliability of the network connection.

Note: The above code is only an example, and should be adjusted and processed accordingly in actual projects according to specific circumstances.
