Question

我无法在camel中使用CLIENT_ACKNOWLEDGE模式确认JMS消息。在深入挖掘堆栈跟踪后，我发现 AbstractMessageListenerContainer 中的 message.acknowledge（） 总是被执行，这会导致auto-ack行为。我配置错了吗？

org.springframework.jms.listener.AbstractMessageListenerContainer.commitIfNecessary（Session，Message）

protected void commitIfNecessary(Session session, Message message) throws JMSException {
        // Commit session or acknowledge message.
        if (session.getTransacted()) {
            // Commit necessary - but avoid commit call within a JTA transaction.
            if (isSessionLocallyTransacted(session)) {
                // Transacted session created by this container -> commit.
                JmsUtils.commitIfNecessary(session);
            }
        }
        else if (message != null && isClientAcknowledge(session)) {
            message.acknowledge();
        }
    }

弹簧配置

<bean id="jms" class="org.apache.camel.component.jms.JmsComponent">
    <property name="connectionFactory" ref="cachedConnectionFactory" />
    <property name="asyncConsumer" value="true" />
    <property name="acknowledgementModeName" value="CLIENT_ACKNOWLEDGE" />
</bean>

<bean id="cachedConnectionFactory"
    class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="targetConnectionFactory" ref="connectionFactory" />
    <property name="sessionCacheSize" value="30" />
</bean>

骆驼路线

from(jmsTerminalRequest).routeId("generic-jms-inbound").setExchangePattern(ExchangePattern.InOnly).threads(5, 20, "generic-jms-inbound").bean(clientAckProcessor).to("...")

您可以做的是在路由消耗端点定义中指定确认模式：

from("...?maxConcurrentConsumers=20&acknowledgementModeName=CLIENT_ACKNOWLEDGE")
    .bean(clientAckProcessor)
    .to("...")

具有CLIENT_ACKNOWLEDGE模式的Camel JMS无法正常工作
