在 Spring Boot 中通过 ActiveMQ Artemis 发送异步消息时如何创建会话工厂?

How to create Session Factory when sending async messages via ActiveMQ Artemis in Spring Boot?

我正在尝试从 sender Spring Boot app to a receiver Spring 启动应用向主题发送简单消息。但我不断收到两个例外。

接收器中出现第一个异常Spring启动应用程序:

javax.jms.JMSException: Failed to create session factory

几秒钟后,发件人应用中出现以下异常:

我正在关注 Spring 引导微服务上的 Udemy course,其中第 13 章和第 14 章专门介绍 JMS 消息传递,因此,除了 [=67 的版本之外,我的配置几乎相同=] Boot,我的是 2.6.6,教练的是 2.1.x 或类似的东西。我必须保留 2.6.6,因为我的项目中还有其他一些东西。

我确实设法通过 Docker 启动了 Active MQ 服务器,就像这样:

C:\Users\Miljan>docker run -it --rm  -p 8161:8161 -p 61616:61616 vromero/activemq-artemis

在运行一张图片之前,我必须下载image,我可以看到服务器是运行:

此外,我可以登录控制台(用户名:artemis;密码:simetraehcapa;):

发件人应用中的其他配置:

@EnableAsync
@EnableScheduling
@Configuration
public class AsyncConfig {

    public static final String EXECUTOR = "SchedulerExecutor";

    @Bean(name = EXECUTOR)
    public Executor asyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(2);
        executor.setMaxPoolSize(2);
        executor.setQueueCapacity(50);
        executor.setThreadNamePrefix(EXECUTOR + "-");
        executor.initialize();
        return executor;
    }
}

@Configuration
public class JmsConfig {

    public static final String QUEUE = "queue";

    @Bean // Serialize message content to json using TextMessage
    public MessageConverter jacksonJmsMessageConverter(ObjectMapper objectMapper) {
        MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
        converter.setTargetType(MessageType.TEXT);
        converter.setTypeIdPropertyName("_type");
        converter.setObjectMapper(objectMapper);
        return converter;
    }
}

spring.artemis.mode=native
spring.artemis.host=localhost
spring.artemis.port=8161
spring.artemis.user=artemis
spring.artemis.password=simetraehcapa

最后,我实际发送消息的方式是通过简单的 GET 请求 (http://localhost:8080/send):

@GetMapping("/send")
public void sendMessage(){
    Student s = new Student("MIKE");
    this.jmsTemplate.convertAndSend(JmsConfig.QUEUE, s);
}

和听众class:

@Component
@EnableJms
public class Listener {

    @Autowired
    private JmsTemplate jmsTemplate;

    @JmsListener(destination = "queue")
    public void listen(Student student){
        System.out.println(student);
    }
}

所以我的问题是:

  1. 如何配置会话工厂?
  2. 我是否遗漏了一些我不知道的其他配置?

我认为问题出在您配置中的这一行:

spring.artemis.port=8161

这指向 ActiveMQ Artemis 中的嵌入式 Web 服务器使用的 HTTP 端口。这不适用于 JMS 客户端。你应该使用:

spring.artemis.port=61616
