javax.net.ssl.SSLException: 连接重置
是一个常见的网络通信异常,通常发生在客户端与服务器之间的SSL/TLS连接过程中。这个异常表示服务器在处理请求时突然关闭了连接。
SSL(Secure Sockets Layer)和TLS(Transport Layer Security)是用于在网络上提供安全通信的协议。它们通过加密数据来保护数据的机密性和完整性。
以下是一个简单的Java示例,展示如何处理SSL异常并进行重试:
import javax.net.ssl.SSLException;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;
public class SSLExceptionExample {
public static void main(String[] args) {
String urlString = "https://example.com";
int maxRetries = 3;
int retryCount = 0;
while (retryCount < maxRetries) {
try {
URL url = new URL(urlString);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
int responseCode = connection.getResponseCode();
System.out.println("Response Code: " + responseCode);
break;
} catch (SSLException e) {
System.err.println("SSLException occurred: " + e.getMessage());
retryCount++;
if (retryCount >= maxRetries) {
System.err.println("Max retries reached. Exiting.");
} else {
System.out.println("Retrying... (" + retryCount + "/" + maxRetries + ")");
}
} catch (IOException e) {
System.err.println("IOException occurred: " + e.getMessage());
break;
}
}
}
}
