发布者应等待经纪人可用

Question

I have a simple publisher, which sends messages to a queue.

<int:channel id="publishChannel"/>
<int-jms:outbound-channel-adapter channel="publishChannel" destination="testQueue" session-transacted="true"/>

@Publisher(channel = "publishChannel")
public String sendMessage (String text) {
    return text;
}

If the broker crashes, the publisher throws an MessageHandlingException.

Is it possible to block the publisher, till the broker is available again or to make a periodic retry?

Answer 1

You can add a retry advice to the outbound adapter .

<int-jms:outbound-channel-adapter channel="publishChannel" destination="testQueue" session-transacted="true>
    <int:request-handler-advice-chain>
        <ref bean="myRetryAdvice" />
    </request-handler-advice-chain>
</int-jms:outbound-channel-adapter>

You can configure the advice with a backoff policy (eg exponential) and to take some action when retries are exhausted (rather than throwing the final exception).
