Spring JMS侦听器确认

Question

我使用JMS从IBM MQ message Broker发送接收消息。我目前正在处理侦听器服务，抛出未处理的异常和消息发送回队列而没有确认。我希望服务重试一个可配置的次数，并抛出表示监听器服务不可用的完全异常消息。

我的监听器和容器工厂如下所示。

@JmsListener(destination = "testqueue", containerFactory = "queuejmsfactory")
public void consumer(String message) throws JMSException 
{ handle(message); }

@Bean(name = "queuejmsfactory") public JmsListenerContainerFactory getQueueTopicFactory(ConnectionFactory con , 
DefaultJmsListenerContainerFactoryConfigurer config) 
{ DefaultJmsListenerContainerFactory d = new DefaultJmsListenerContainerFactory(); 
d.setSessionTransacted(true); 
d.setSessionAcknowledgeMode(Session.AUTO_ACKNOWLEDGE); 
config.configure(d,con); 
return d; }

@Override
public void onMessage(Mesage mes, Session ses) throws JMSException 
{ try 
{ TestMessage txtMessage = (TextMessage)message; 
handle(txtMessage); ses.commit(); 
} catch (Exception exp) 
{ if (shouldRollback(message))
{ ses.rollback();} 
else{logger,warn("moved to dlq"); 
ses.commit(); 
} 
} }

private boolean shouldRollback(Message mes) throws JMSException 
{ int rollbackcount = mes.getIntProperty("JMSXDeliveryCount"); 
return (rollbackcount <= maxRollBackCountFromApplication.properties)
}

@JmsListener(destination = "testqueue", containerFactory = "queuejmsfactory")
    public void consumer(Message message) throws JMSException 
    { 
        try {TestMessage txtMessage = (TextMessage)message;
            handle(txtMessage);}
        catch(Excepton ex) {
            if shouldRollback(message)
            {throw ex;}
            else {logger.warn("moved to dlq")}

    }}

    private boolean shouldRollback(Message mes) throws JMSException 
    { int rollbackcount = mes.getIntProperty("JMSXDeliveryCount"); 
    return (rollbackcount <= maxRollBackCountFromApplication.properties)
    }

    @Bean(name = "queuejmsfactory") public JmsListenerContainerFactory getQueueTopicFactory(ConnectionFactory con , 
    DefaultJmsListenerContainerFactoryConfigurer config) 
    { DefaultJmsListenerContainerFactory d = new DefaultJmsListenerContainerFactory(); 
    d.setSessionTransacted(true); 
    d.setSessionAcknowledgeMode(Session.AUTO_ACKNOWLEDGE); 
    config.configure(d,con); 
    return d; }

@JmsListener(destination = "testqueue", containerFactory = "queuejmsfactory")
    public void consumer(Message message,
                               @Header(JmsHeaders.CORRELATION_ID) String correlationId,
                               @Header(name = "jms-header-not-exists") String nonExistingHeader,
                               @Headers Map<String, Object> headers,
                               MessageHeaders messageHeaders,
                               JmsMessageHeaderAccessor jmsMessageHeaderAccessor) {}

您可以将session作为另一个参数添加到JMSListener方法中。
