java客户端连接测试某个activemq的代码

好的，以下是Java客户端连接测试某个ActiveMQ的代码示例：

import javax.jms.*;

import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;

public class ActiveMQClient {
    private static String url = ActiveMQConnection.DEFAULT_BROKER_URL;
    private static String subject = "TEST_QUEUE";
    
    public static void main(String[] args) throws JMSException {
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);
        Connection connection = connectionFactory.createConnection();
        connection.start();
        
        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
        Destination destination = session.createQueue(subject);
        MessageProducer producer = session.createProducer(destination);
        TextMessage message = session.createTextMessage("Hello World!");
        producer.send(message);
        System.out.println("Sent message '" + message.getText() + "'");
        
        MessageConsumer consumer = session.createConsumer(destination);
        Message receivedMessage = consumer.receive();
        if (receivedMessage instanceof TextMessage) {
            TextMessage textMessage = (TextMessage) receivedMessage;
            System.out.println("Received text message '" + textMessage.getText() + "'");
        } else {
            System.out.println("Received message was not a text message");
        }
        
        connection.close();
    }
}

请注意，这只是一个示例代码，你需要根据你的具体情况进行修改。同时，请确保你已经正确导入了 ActiveMQ 的 JAR 包并且已经启动了 ActiveMQ 服务。
