Question

我正在将Spring从4.x.x更新到Spring 5.0.3。该项目使用ActiveMQ版本5.15.3。当我尝试使用最新版本的Spring部署应用程序时，我收到此错误：

我注意到ActiveMQ将Spring版本“4.3.9”作为依赖项。此版本在“AbstractHandlerMapping”中没有“obtainApplicationContext”方法，因此存在问题。有没有办法从activemq-all包中排除Spring库？

Answer 1

我认为这也是我的问题，但我最终在TomEE上部署了我的Spring webapp，以便成功连接并使用ActiveMQ托管并在内部运行到该Tomcat容器。

我使用的是Spring 5.0.3-RELEASE和activemq-client 5.15.3。我并不需要在maven阴影超级罐中使用activemq-all。

@Configuration
public class MyConfig {

  @Bean
  public SingleConnectionFactory connectionFactory() {
      ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("vm://localhost");
      ((ActiveMQConnectionFactory) connectionFactory)
            // See http://activemq.apache.org/objectmessage.html why we set trusted packages
            .setTrustedPackages(new ArrayList<String>(Arrays.asList("com.mydomain", "java.util")));
    return new SingleConnectionFactory(connectionFactory);
}

  @Bean
  @Scope("prototype")
  public JmsTemplate jmsTemplate() {
      return new JmsTemplate(connectionFactory());
  }

  @Bean
  public Queue myQueue() throws JMSException {
      Connection connection = connectionFactory().createConnection();
      connection.start();
      Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
      Queue queue = session.createQueue("message-updates");
      return queue;
  }
}

@Component
public class MyQueueImpl implements MyQueue {

  @Inject
  private JmsTemplate jmsTemplate;

  @Inject
  private Queue myQueue;

  @PostConstruct
  public void init() {
   jmsTemplate.setReceiveTimeout(JmsTemplate.RECEIVE_TIMEOUT_NO_WAIT);
  }

  @Override
  public void enqueue(Widget widget) {
      jmsTemplate.send(myQueue, new MessageCreator() {
          @Override
          public Message createMessage(Session session) throws JMSException {
              return session.createObjectMessage(widget);
          }
      });
  }

  @Override
  public Optional<Widget> dequeue() {
    Optional<Widget> widget = Optional.empty();
    ObjectMessage message = (ObjectMessage) jmsTemplate.receive(myQueue);
    try {
        if (message != null) {
            widget = Optional.ofNullable((Widget) message.getObject());
            message.acknowledge();
        }
    } catch (JMSException e) {
        throw new UncategorizedJmsException(e);
    }

    return widget;
  }
}

Answer 2

感谢上面的MatthewK。我也发现了。 ActiveMQ-all内部都包装了spring的一个版本（当前是4.x版本）。与Spring v.5之间有一些向后兼容的更改。我本人在其他春季班中遇到了一种新方法。可能导致这种问题（我的情况下没有这种方法异常）。我在activeMQ 5.15.4和Spring 5.0.7中遇到了这个问题。最后，我改用细颗粒的罐子解决了。我必须使用所有这些：activemq-broker，activemq-client，activemq-pool，activemq-kahadb-store，activemq-spring

activemq-all“5.15.3”不适用于Spring 5
