Tomcat未能与Artemis MQ进行交流

Question

我想使用JMS安排消息延迟。为此，我正在使用Artemis MQ使用JMS 2.0，并且该消息已在编译时间成功安排，但是当我在Tomcat中部署并尝试以延迟发送消息时，它说：

java.lang.illegalstateException：setDeliveryDelay需要JMS 2.0

我猜想Tomcat无法与我设置的Artemis服务器进行正确的通信。因此，我的系统中有两个服务器设置：Tomcat和Artemis。是因为Tomcat无法与Artemis沟通吗？如果是这样，那么为什么我的春季启动在构建的tomcat服务器会检测到Artemis，但我的独立tomcat却没有？

我的JMS消息发件人的源代码是：

@Service
public class TransferServiceImpl implements TransferService {
    @Autowired
    private JmsTemplate jmsTemplate;
    @Override
    public void transfertoJMS(Transaction transaction) {
        System.out.println("Sending a transaction.");
        jmsTemplate.setDeliveryDelay(20000);
        jmsTemplate.convertAndSend(destinationQueue, transaction);
    }
}

Answer 1

您与两个冲突的依赖关系发生了冲突。以下依赖性是ActiveMQ 5.x(！(：

<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-broker</artifactId>
</dependency>

Spring可能正在从该依赖项中找到JMS 1.0规格，该依赖关系覆盖了您的classPath上的JMS 2.0规格，并在Spring寻找启动ConnectionFactory时使用必要的JMS接口时给您java.lang.IllegalStateException。

。

如果您想要一个嵌入式经纪人，则spring-boot-starter-artemis已经包含它，因此您应该能够删除activemq-broker依赖性而不会出现问题。
