是的，AppDynamics可以计算从JMS队列和主题中应用程序消耗和发布的消息数量。下面是Java代码示例：

import com.appdynamics.agent.api.AppdynamicsAgent;
import com.appdynamics.agent.api.JmsProducerStats;
import com.appdynamics.agent.api.JmsConsumerStats;
import com.appdynamics.agent.api.JmsDestinationType;

public class JmsMessageCount {

    public static void main(String[] args) {

        AppdynamicsAgent.initialize();

        // JMS queue name
        String jmsQueueName = "QueueName";

        // JMS topic name
        String jmsTopicName = "TopicName";

        // Get producer message count for JMS queue
        JmsProducerStats jmsQueueProducerStats = AppdynamicsAgent.getJmsProducerStats(jmsQueueName, JmsDestinationType.QUEUE);
        long jmsQueueProducerMessageCount = jmsQueueProducerStats.getMessageCount();

        // Get consumer message count for JMS queue
        JmsConsumerStats jmsQueueConsumerStats = AppdynamicsAgent.getJmsConsumerStats(jmsQueueName, JmsDestinationType.QUEUE);
        long jmsQueueConsumerMessageCount = jmsQueueConsumerStats.getMessageCount();

        // Get producer message count for JMS topic
        JmsProducerStats jmsTopicProducerStats = AppdynamicsAgent.getJmsProducerStats(jmsTopicName, JmsDestinationType.TOPIC);
        long jmsTopicProducerMessageCount = jmsTopicProducerStats.getMessageCount();

        // Get consumer message count for JMS topic
        JmsConsumerStats jmsTopicConsumerStats = AppdynamicsAgent.getJmsConsumerStats(jmsTopicName, JmsDestinationType.TOPIC);
        long jmsTopicConsumerMessageCount = jmsTopicConsumerStats.getMessageCount();

        System.out.println("JMS Queue Producer Message Count: " + jmsQueueProducerMessageCount);
        System.out.println("JMS Queue Consumer Message Count: " + jmsQueueConsumerMessageCount);
        System.out.println("JMS Topic Producer Message Count: " + jmsTopicProducerMessageCount);
        System.out.println("J
