我正在尝试为消息放置持久订阅者,以使它们即使在服务器重新启动后也能保留在主题中。
但是在配置过程中,我得到与xml相关的错误:
这是我的配置xml:

</beans>
但是在
message-driven-channel-adapter
中,以下属性给出了错误:它说:
在此行找到多个注释:
cvc-complex-type.3.2.2:不允许属性“ subscription-durable”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'。
但是在更多示例中,我可以看到以下属性正常工作。
subscription-durable="true"
durable-subscription-name="myDurableSubscription"
那我的配置可能出了什么问题。
编辑:
POM.xml中的Spring Integration依赖项
<!-- Spring Integration -->
<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-core</artifactId>
<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>
编辑:
请参阅所附图片:
另请参阅我的日志,该日志表明已调用目标方法,而该方法应该在客户端使用消息时发生。
请帮忙。
最佳答案
您正在使用哪个版本的Spring Integration?超过4年以前,在2.1.0.RELEASE版本中添加了对持久订阅的支持。
当前版本是4.2.0.RELEASE。
编辑:
我忘了提到您需要长期订阅的客户ID。
您是否查看了日志消息?这似乎很清楚...
14:12:39.557 WARN [jmsIn.container-1] [org.springframework.jms.listener.DefaultMessageListenerContainer]对于目标“ topic://topic.demo”,JMS消息侦听器调用程序的设置失败-试图恢复。原因:如果不在Connection上指定唯一的clientID,则无法创建持久订户
将clientId添加到您的连接工厂...
<property name="clientId" value="myClient"/>
