java - 持久订阅 ActiveMQ

Question

我正在尝试为我的消息设置持久订阅者，以便即使在服务器重新启动后它们也会在主题中持久存在。

但是在配置过程中我遇到了与 xml 相关的错误:

这是我的配置文件:

    <!-- Create a channel for a listener that will consume messages-->
    <int:channel id="listenerChannel" />

    <int-jms:message-driven-channel-adapter id="messageDrivenAdapter"
                                            channel="getPayloadChannel"
                                            subscription-durable="true"
                                            durable-subscription-name="myDurableSubscription"
                                            destination-name="topic.myTopic"
                                            pub-sub-domain="true" />

    <int:channel id="getPayloadChannel" />

    <int:service-activator input-channel="getPayloadChannel" output-channel="listenerChannel" ref="retrievePayloadServiceImpl" method="getPayload" />

</beans>

但是在 message-driven-channel-adapter 中，以下属性给出了一个错误:

它说:

在此行发现多个注释:

• cvc-complex-type.3.2.2:属性“subscription-durable”不允许出现在元素“int-jms:message-driven-channel-”中 适配器”。
• cvc-complex-type.3.2.2:属性“durable-subscription-name”不允许出现在元素“int-jms:message-driven-channel-”中 适配器”。

但在更多示例中，我可以看到以下属性工作正常。

• subscription-durable="true"

• durable-subscription-name="myDurableSubscription"

那我的配置可能有什么问题

编辑:POM.xml 中的 Spring Integration 依赖项

<!-- Spring Integration -->
        <dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-core</artifactId>

        </dependency>

请看附图:

另请参阅我的日志，它表示已调用目标方法，这应该在客户端使用消息时发生。 请帮忙。

Answer 1

您使用的是哪个版本的 Spring Integration？ 4 年前，版本 2.1.0.RELEASE 中添加了对持久订阅的支持。

当前版本是 4.2.0.RELEASE。

编辑:

我忘了说您需要一个客户端 ID 才能进行持久订阅。

您查看日志消息了吗？这似乎很清楚......

14:12:39.557 WARN [jmsIn.container-1][org.springframework.jms.listener.DefaultMessageListenerContainer] Setup of JMS message listener invoker failed for destination 'topic://topic.demo' - trying to recover. Cause: You cannot create a durable subscriber without specifying a unique clientID on a Connection

将 clientId 添加到您的连接工厂...

    <property name="clientId" value="myClient"/>
