Spring DefaultJmsListenerContainer 监听多个队列调优

Question

we have 50 @JMSListener classes connecting to 50 different SQS Queues from same application. is it better to use the different listener containers for each queue.

We are using the same ListenerContainer with SQSConnectionFactory for sending and receiving the messages. Will it help in performance if we add separate ListenerContainer for queues and multiple JMSTemplates to to send messages to queues with high number of messages. my configs are as follows.

 public void sqsContainerFactory(){ connectionFactory = new SQSConnectionFactory( new ProviderConfiguration(), AmazonSQSClientBuilder.standard().withRegion(region).withCredentials(new DefaultAWSCredentialsProviderChain()) ); } //Used in all Listeners as containerFactory @Bean public JmsListenerContainerFactory<?> sqsFactory() { DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory(); factory.setConnectionFactory(this.connectionFactory); factory.setDestinationResolver(new DynamicDestinationResolver()); factory.setConcurrency("1-25"); factory.setSessionAcknowledgeMode(Session.CLIENT_ACKNOWLEDGE); return factory; } //Used to send messages to SQS @Bean("SQS") @Primary public JmsTemplate defaultJmsTemplate() { return new JmsTemplate(this.connectionFactory); }

could you please advise

If you have 50 @JMSListener classes listening on 50 queues, then you already have 50 ListenerContainers. I don't know of any way to have a DefaultMessageListenerContainer listen on more than one queue.

If you are having performance issues, look at the org.messaginghub.pooled.jms.JmsPoolConnectionFactory or the org.apache.activemq.jms.pool.PooledConnectionFactory . By default, the JMSTemplate will create a new JMS connection and session for every message sent. This is very expensive. Depending on your configuration, the DefaultMessageListenerContainer can also do this for every message received.
