如何在ActiveMQ中使用PooledConnectionFactoryBean

Question

首先，我是JSM的新手。 我正在嘗試為JMS ActiveMQ創建連接池使用連接工廠ActiveMQConnectionFactory我成功發送/接收消息，但是使用PooledConnectionFactoryBean卻失敗，並出現以下錯誤：

這是源代碼：

package jmxproducer;

import javax.jms.*;
import org.apache.activemq.ActiveMQConnectionFactory;
import org.apache.activemq.pool.PooledConnectionFactoryBean;

public class JMXProducerTest implements Runnable {

    private String message;

    public JMXProducerTest(String message) {
        this.message = message;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    @Override
    public void run() {
        try {
            ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");

            PooledConnectionFactoryBean pool = new PooledConnectionFactoryBean();
            pool.setConnectionFactory(connectionFactory);

            // Create a Connection
            Connection connection = connectionFactory.createConnection();
            connection.start();

            // Create a Session
            Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

            // Create the destination (Topic or Queue)
            Destination destination = session.createQueue("MY.QUEUE");

            // Create a MessageProducer from the Session to the Topic or Queue
            MessageProducer producer = session.createProducer(destination);
            producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
            // Create a messages
            TextMessage msg = session.createTextMessage(message);
            producer.send(msg);
            session.close();
            connection.close();
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }
}

我錯過了什么？ 我將這個jar添加到類路徑中：activemq-all-5.8.0.jar

謝謝，kdureidy

Answer 1

您是否已將Spring庫添加到您的項目中？

錯誤

java.lang.ClassNotFoundException: org.springframework.beans.factory.FactoryBean

似乎表明您的項目中缺少spring-beans-X.jar（其中X是您缺少的Spring版本）。
