Frank's questions

从 Web 控制台浏览我的 ActiveMQ Artemis 2.37.0 消息时，我看到一个newrelic属性。知道这是怎么回事吗？

[{"newrelic":"eyJkIjp7ImFjIjoiMTIxMjEwMiIsInByIjoxLjQ3MTk0LCJ0","x-opt-delivery-time":1726171200241,"x-opt-jms-dest":0,"address":"scheduled","creationTime":1726168127157,"x-opt-jms-msg-type":3,"messageID":515,"priority":4,"userID":"ID:ID:eb421cec-9cfa-49b3-b730-cf95485863da:1:1:1-1",,"durable":true,"tracestate":"1212102@nr=0-0-1212102-398731796-08b44ca926d53eec-b3094d0d0d351a97,","traceparent":"00-3ea7d1cdf9df58945f523cf2acc6f21f","expiration":0,"to":"scheduled","contentType":"application/octet-stream","timestamp":1726168127157}]

我有一个非常简单的 Spring Boot 2.7.6 ActiveMQ Artemis 应用程序，用于侦听消息。

package broker.consumer;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.apache.activemq.broker.BrokerService;
import org.springframework.jms.annotation.JmsListener;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public BrokerService broker() throws Exception {
        BrokerService broker = new BrokerService();
        broker.addConnector("tcp://localhost:61616");
        broker.setPersistent(false);
        broker.start();
        return broker;
    }

    @JmsListener(destination = "foo")
    public void listen(String in) {
        System.out.println(in);
    }
}

然后我有另一个 Spring Boot 应用程序，它生成消息并将它们发送到代理地址。

package broker.producer;

import org.apache.activemq.artemis.jms.client.ActiveMQConnectionFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.support.destination.JndiDestinationResolver;
import org.springframework.stereotype.Service;

@Service
public class JmsProducer {

  @Value("${spring.artemis.broker-url}")
  private String brokerUrl;

  @Value("${spring.jms.template.default-destination}")
  private String defaultDestination;

  Logger log = LoggerFactory.getLogger(JmsProducer.class);

  @Bean
  public ActiveMQConnectionFactory activeMQConnectionFactory() {
      log.info("BrokerUrl: {}", brokerUrl);
      ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(brokerUrl);

      return activeMQConnectionFactory;
  }

  @Bean
  public JndiDestinationResolver jndiDestinationResolver() {
    return new JndiDestinationResolver();
  }

  @Bean
  public JmsTemplate jmsTemplate() {
    JmsTemplate template = new JmsTemplate();
    template.setConnectionFactory(activeMQConnectionFactory());
    template.setPubSubDomain(false); // false for a Queue, true for a Topic
    template.setDefaultDestinationName(defaultDestination);

    return template;
  }


  public void send(String message) {
    JmsTemplate jmsTemplate = jmsTemplate();

    log.info("Sending message='{}'", message);
    jmsTemplate.convertAndSend(message);
    log.info("Sent message='{}'", message);
  }
}

这application.properties对于两个应用程序来说都很简单。

spring.artemis.mode=EMBEDDED
spring.artemis.broker-url=tcp://localhost:61616
spring.artemis.user=admin
spring.artemis.password=secret
spring.artemis.embedded.enabled=true

spring.jms.template.default-destination=my-queue-1

然后我启动每个应用程序并尝试调用send方法，但我不断从生产者应用程序收到此错误。

2024-01-15 15:50:28.462 ERROR 1012 --- [-netty-threads)] org.apache.activemq.artemis.core.client : AMQ214013: Failed to decode packet

消费者应用程序显示此错误消息：
