Question

我为入站通道适配器提供了以下Spring Integration配置：

<bean id="inputQueue"
    class="org.apache.activemq.command.ActiveMQQueue">
    <constructor-arg value="INBOUND.QUEUE" />
</bean>
<int:channel id="inputChannel">
    <int:queue ref="inputQueue"></int:queue>
</int:channel>

<jms:inbound-channel-adapter
    channel="inputChannel" connection-factory="activemqConnectionFactory"
    destination-name="inputQueue"></jms:inbound-channel-adapter>

我在启动应用程序时遇到问题，因为它无法创建inputChannel bean。请帮忙。

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'inputChannel': Unsatisfied dependency expressed through constructor parameter 0: Could not convert argument value of type [org.apache.activemq.command.ActiveMQQueue] to required type [java.util.Queue]: Failed to convert value of type 'org.apache.activemq.command.ActiveMQQueue' to required type 'java.util.Queue'; nested exception is java.lang.IllegalStateException: Cannot convert value of type 'org.apache.activemq.command.ActiveMQQueue' to required type 'java.util.Queue': no matching editors or conversion strategy found

Answer 1

"org.apache.activemq.command.ActiveMQQueue未实现Java.util.Queue。这就是你到目前为止在堆栈跟踪中所拥有的。另一方面，您不需要向频道发布<queue>声明：您定义了一个JMS频道适配器来处理ActiveMQ。

您声明destination-name="inputQueue"的另一个问题是 bean名称。您应该考虑仅使用destination，它确实是对bean的引用，或者只是在INBOUND.QUEUE中使用destination-name。
