spring rabbitmq wait confirm timeout - spring-rabbit

Question

spring-rabbit version:1.7.4.RELEASE
this is my code:
#Configuration
public class RabbitmqConfiguration {
public RabbitmqConfiguration(RabbitTemplate rabbitTemplate,ConfirmCallback confirmCallback) throws Exception {
rabbitTemplate.setConfirmCallback(confirmCallback);
ObjectMapper mapper = new ObjectMapper();
mapper.setPropertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);
rabbitTemplate.setMessageConverter(new Jackson2JsonMessageConverter(mapper));
}
}
#Component
#Slf4j
public class OrderStatusChangeComponentImpl implements OrderStatusChangeComponent,ConfirmCallback{
#Autowired
private RabbitTemplate rabbitTemplate;
#Autowired
private OrderMessageLogComponent orderMessageLogComponent;
#Autowired
private Gson gson;
/*
* (non-Javadoc)
*
* #see org.springframework.amqp.rabbit.core.RabbitTemplate.ConfirmCallback#
* confirm(org.springframework.amqp.rabbit.support.CorrelationData, boolean,
* java.lang.String)
*/
public void confirm(CorrelationData correlationData, boolean ack, String cause) {
long nowTime = System.nanoTime();
String uuid = correlationData.getId();
if (ack) {
orderMessageLogComponent.deleteOrderMessageLogByUUID(uuid);
} else {
log.error(cause, nowTime);
}
}
i test rabbitmq send msg by jmeter about 512 thread and 1000 loops;
i see log have so much error.
Channel shutdown: clean channel shutdown; protocol method: #method<channel.close>(reply-code=406, reply-text=TIMEOUT WAITING FOR ACK, class-id=0, method-id=0)
finally my application cannot connection rabbitmq.
btw my rabbitmq server is healty.

Answer 1

Try doing your send() within a RabbitTemplate.invoke() and invoke a template.waitForConfirmsOrDie() with a longer timeout.
If you are using invoke() and don't do that, the framework will only wait 5000ms for confirms.
If you are not using invoke(), it's not clear how you can get that close error.

Answer 2

public void confirm(CorrelationData correlationData, boolean ack, String cause) {
long nowTime = System.nanoTime();
String uuid = correlationData.getId();
if (ack) {
orderMessageLogComponent.deleteOrderMessageLogByUUID(uuid);
} else {
log.error("消息发送失败，消息唯一标识为{}，具体原因为{}，当前时间为{}", uuid, cause, nowTime);
}
}
#Override
#Async(MsgSendAsyncConfig.MSGSEND_SYNC_POOL)
public void deleteOrderMessageLogByUUID(String uuid) {
orderMessageLogService.deleteOrderMessageLogByUUID(uuid);
}
