Question

我想使用Solace JMS API订阅一个持久性主题。但是，当我启动我的应用程序时，它抛出以下错误：

[Context_3_ReactorThread]信息com.solacesystems.jcsmp.impl.flow.BindRequestTask-错误响应（503）-持久主题端点超出了最大客户端数

我在centos 7上使用了最新的solace docker镜像。该镜像版本为solace-pubsub-standard（9.1.0.201）。

下面是我的代码：

@Bean
public SolConnectionFactory connectionFactory() {
    SolConnectionFactory connectionFactory = new SolConnectionFactoryImpl();
    connectionFactory.setHost("10.69.94.182");
    connectionFactory.setUsername("default");
    connectionFactory.setPassword("default");
    connectionFactory.setVPN("default");
    connectionFactory.setDynamicDurables(true);
    return connectionFactory;
}


@Bean
public DefaultJmsListenerContainerFactory pubSubContainerFactory(ConnectionFactory connectionFactory) {
    DefaultJmsListenerContainerFactory listenerContainerFactory = new DefaultJmsListenerContainerFactory();
    listenerContainerFactory.setConnectionFactory(connectionFactory);
    listenerContainerFactory.setPubSubDomain(true);
    listenerContainerFactory.setSubscriptionDurable(true);
    return listenerContainerFactory;
}



@JmsListener(destination = "com.schindler.ioee.gdcs.Callback", containerFactory = "pubSubContainerFactory")
public void processCallback(Message message) {
    /*message.getHeaders().entrySet().forEach(item -> log.info("{}:{}", item.getKey(), item.getValue()));*/
    log.info("[CONSUMER] topic={}, message={}", message.getHeaders().get("jms_destination"), message.getPayload());

}

我尝试将主题终结点的最大绑定数设置为1024，这也会引发上述错误。

任何人都可以提供一些帮助。预先谢谢你！

阅读文档https://docs.solace.com/Solace-JMS-API/Creating-Durable-Topic-S.htm后，问题已解决。我有2个订阅，但是我想在注释中添加一个订阅。如果缺少订阅名称，spring将使用默认名称“ org.springframework.jms.listener.adapter.MessagingMessageListenerAdapter”作为订阅名称。根据该文档，一个会话不能预订同一主题端点两次。因此引发了错误。

我的最终消费者代码如下：

@Component
@Slf4j
public class MessageConsumer {

    @JmsListener(destination = "com.schindler.ioee.gdcs.Callback", containerFactory = "pubSubContainerFactory", subscription = "com.schindler.ioee.gdcs.Callback")
    public void processCallback(Message message) {
        // message.getHeaders().entrySet().forEach(item -> log.info("{}:{}", item.getKey(), item.getValue()));
        log.info("[CONSUMER] topic={}, message={}", message.getHeaders().get("jms_destination"), message.getPayload());

    }

    @JmsListener(destination = "com.schindler.ioee.gdcs.Symptom", containerFactory = "pubSubContainerFactory", subscription = "com.schindler.ioee.gdcs.Symptom")
    public void processSymptom(Message message) {
        // message.getHeaders().entrySet().forEach(item -> log.info("{}:{}", item.getKey(), item.getValue()));
        log.info("[CONSUMER] topic={}, message={}", message.getHeaders().get("jms_destination"), message.getPayload());

    }

    @JmsListener(destination = "com.schindler.ioee.gdcs.Equipment", containerFactory = "pubSubContainerFactory", subscription = "com.schindler.ioee.gdcs.Equipment")
    public void processEquipment(Message message) {
        // message.getHeaders().entrySet().forEach(item -> log.info("{}:{}", item.getKey(), item.getValue()));
        log.info("[CONSUMER] topic={}, message={}", message.getHeaders().get("jms_destination"), message.getPayload());

    }


    @JmsListener(destination = "t/cn/rtc/*/status", subscription = "sms_mqtt_subscription", containerFactory = "pubSubContainerFactory")
    public void processStatus(Message message) {
        // message.getHeaders().entrySet().forEach(item -> log.info("{}:{}", item.getKey(), item.getValue()));
        log.info("[CONSUMER] topic={}, message={}", message.getHeaders().get("jms_destination"), new String((byte[]) message.getPayload()));

    }
}

无法通过Solace JMS订阅持久主题
