在解决“Apache Artemis - 日志 AMQ212037 连接失败和连接被对等方重置 [code=GENERIC_EXCEPTION]”问题时,以下是一些可能的解决方法和相关的代码示例:
import java.net.InetAddress;
import java.net.InetSocketAddress;
import java.net.Socket;
public class NetworkUtils {
public static boolean isReachable(String host, int port, int timeout) {
try (Socket socket = new Socket()) {
InetAddress address = InetAddress.getByName(host);
InetSocketAddress socketAddress = new InetSocketAddress(address, port);
socket.connect(socketAddress, timeout);
return true;
} catch (Exception e) {
return false;
}
}
}
// 使用示例
boolean isReachable = NetworkUtils.isReachable("example.com", 80, 5000);
if (isReachable) {
System.out.println("网络连接正常");
} else {
System.out.println("网络连接失败");
}
import java.net.ServerSocket;
import java.io.IOException;
public class FirewallUtils {
public static boolean isPortOpen(int port) {
try (ServerSocket serverSocket = new ServerSocket(port)) {
return true;
} catch (IOException e) {
return false;
}
}
}
// 使用示例
boolean isPortOpen = FirewallUtils.isPortOpen(61616);
if (isPortOpen) {
System.out.println("端口开放");
} else {
System.out.println("端口关闭");
}
tcp://localhost:61616
import org.apache.activemq.artemis.api.core.TransportConfiguration;
import org.apache.activemq.artemis.api.core.client.*;
import org.apache.activemq.artemis.api.core.client.ServerLocator;
public class ArtemisConnection {
public static void main(String[] args) throws Exception {
String username = "your_username";
String password = "your_password";
String brokerURL = "tcp://localhost:61616";
TransportConfiguration transportConfiguration = new TransportConfiguration(
"org.apache.activemq.artemis.core.remoting.impl.netty.NettyConnectorFactory");
ServerLocator serverLocator = ActiveMQClient.createServerLocatorWithoutHA(transportConfiguration);
ClientSessionFactory sessionFactory = serverLocator.createSessionFactory();
ClientSession session = sessionFactory.createSession(username, password, false, true, true, false, 1);
// 连接成功,执行其他操作...
}
}
请注意,上述解决方法中的代码示例仅用于演示目的,您需要根据您的实际情况进行相应的修改和调整。此外,还应该根据您的具体问题和环境进一步调查和排除可能导致连接失败和重置的其他原因。
