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保留。

但在配置期间，我收到与xml相关的错误：

这是我的配置xml：

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

    <int-jms:message-driven-channel-adapter id="messageDrivenAdapter"

                                            subscription-durable="true"
                                            durable-subscription-name="myDurableSubscription"
                                            destination-name="topic.myTopic"

    <int:channel id="getPayloadChannel" />

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

</beans>

但在message-driven-channel-adapter以下属性中出现错误：

它说：

在此行找到多个注释：

cvc-complex-type.3.2.2：属性＆＃39;订阅耐用＆＃39;不允许出现在元素＆＃39; int-jms中：message-driven-channel- 适配器＆＃39;
cvc-complex-type.3.2.2：属性＆＃39;持久订阅名称＆＃39;不允许出现在元素＆＃39; int-jms中：message-driven-channel- 适配器＆＃39;

但是在更多的例子中我可以看到下面的属性工作正常。

subscription-durable="true"
durable-subscription-name="myDurableSubscription"

然后我的配置可能出错了。

编辑： POM.xml中的Spring Integration依赖项

<!-- Spring Integration -->
        <dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-core</artifactId>
            <version>4.2.0.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-jms</artifactId>
            <version>4.2.0.RELEASE</version>
        </dependency>

修改

请参阅附图：

另请参阅我的日志，该日志表示已调用目标方法，该方法应在客户端使用消息时发生。请帮忙。

Answer 1

您使用的是什么版本的Spring Integration？ 4年前版本2.1.0.RELEASE中添加了对持久订阅的支持。

当前版本为4.2.0.RELEASE。

修改：

我忘了提到你需要一个持久订阅的客户端ID。

您是否看过日志消息？这看起来很清楚......

14：12：39.557 WARN [jmsIn.container-1] [org.springframework.jms.listener.DefaultMessageListenerContainer] JMS消息监听器调用程序的设置失败，目的地为'topic：//topic.demo' - 尝试恢复。原因：如果未在Connection
上指定唯一的clientID，则无法创建持久订阅者

将clientId添加到连接工厂......

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

持久订阅ActiveMQ
