java - ActiveMQ JDBC持久化问题: ACTIVEMQ_MSGS is always empty

Question

大家!

我正在尝试将 JDBC 持久性与 ActiveMQ 结合使用。所以，当生产者发送消息时，它应该默认保存到ACTIVEMQ_MSGS表中。但当我检查这张表时，它总是空的。我不明白问题出在哪里。

这是 Spring XML 配置

        <bean 
                id="producer"
                class="com.jmsexamples.Producer">
            <property name="connectionFactory" ref="jmsFactory" />  
        </bean>

        <bean id="jdbc_ds" 
                    class="com.mysql.jdbc.jdbc2.optional.MysqlDataSource">

            <property name="user" value="root" />
            <property name="password" value="" />
        </bean>

      <amq:connectionFactory id="jmsFactory" brokerURL="tcp://localhost:61616" />

      <amq:queue id="queue" physicalName="message.queue" />

  <amq:broker useJmx="false" persistent="true">

          <amq:transportConnector uri="vm://localhost:61616" />
        </amq:transportConnectors> 
      </amq:broker>

UPD 生产者代码:

public class Producer{

    private ConnectionFactory connectionFactory;
    private Destination dest;

    public void setConnectionFactory(ConnectionFactory conFact){
        this.connectionFactory = conFact;   
    }

    public void sendMessage(){

        Connection connection = null;
        Session session = null;

        try {

            connection = connectionFactory.createConnection("roman", "sawawluha");
            session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
            dest = new ActiveMQQueue("message.queue");
            MessageProducer producer = session.createProducer(dest);
      for(int i=0;i<10; i++)
      {         
        TextMessage message = session.createTextMessage();

              message.setText("This is text message!");
              producer.send(message);
      }
        } catch(JMSException  e)
        {
            e.printStackTrace();
        } finally
        {
      try {
              session.close();
              connection.close();
                System.out.println("closing");
      } catch(Exception e)
      {
        e.printStackTrace();
      }

    }
    }
}

您在连接工厂和代理传输中有不同的 url。 您可能应该在两个地方都有 tcp://localhost:61616。

无论如何，应该有一些异常(exception)
