利用rabbitmq异步实现来提升程序处理性能

利用rabbitmq提高付款交易处理性能

利用rabbitmq异步实现来提升程序处理性能_ide

近期交易系统出款交易量猛增,从skywalking监控平台查看服务的调用链路(Trace),发现在调用外部三方http接口会耗时将近一半。鉴于出款交易在业务上是异步处理的,所以,商定考虑将调用外部接口的部分改为异步实现。

异步实现,一种方案是线程池。弊端是,线程池是在应用节点内部,集群部署环境下,并不利于多节点的均衡处理。再者,单节点故障时,消息就会丢失,这个比较要命,还要考虑补偿。

最好的方案是借助消息中间件,我们使用rabbitmq。

 

zhenghe-channel应用是springboot项目,异步改为使用rabbitmq来处理,zhenghe-channel既是生产者,又是消费者。

 

SpringBoot工程如何使用Rabbitmq

我们的springboot项目使用rabbitmq,通常是这样子的。一个是标记了@Configuration注解的RabbitConfig类,通过@Bean注解声明broker(exchange、queue,以及binding)。

package com.emax.channel.provider.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Bean;
import org.springframework.amqp.core.*;

/**
* 调用服务商api下发 mq异步实现
* @date 2022-9-20 21:22
*/
@Configuration
@Slf4j
public class LevyPayApiInvokerMqConfig {

@Value("${mq-brokers.levy_pay_api_invoker_queue:levy_pay_api_invoker_queue}")
private String queueName;

@Value("${mq-brokers.levy_pay_api_invoker_exchange:levy_pay_api_invoker_exchange}")
private String exchangeName;

@Bean
public Queue levyPayApiQueue() {
return new Queue(queueName, true);
}

@Bean
DirectExchange levyPayApiExchange() {
return new DirectExchange(exchangeName, true, false);
}

@Bean
Binding levyPayApiBinding(Queue levyPayApiQueue, DirectExchange levyPayApiExchange) {
return BindingBuilder.bind(levyPayApiQueue).to(levyPayApiExchange).withQueueName();
}
}

生产者端,不外乎调用RabbitTemplate#convertAndSend方法。

package com.emax.channel.provider.modules.mq;

import org.springframework.stereotype.Component;
import org.springframework.amqp.core.Binding;
import org.springframework.amqp.rabbit.core.RabbitTemplate;

/**
* 调用服务商api下发 mq异步实现
* @date 2022-9-20 21:22
*/
@Component
@Slf4j
public class LevyPayApiInvokerProducer {

/**
* @see com.emax.channel.provider.config.LevyPayApiInvokerMqConfig#levyPayApiBinding(Queue, DirectExchange)
*/
@Autowired
private Binding levyPayApiBinding;

@Autowired
private RabbitTemplate rabbitTemplate;

public void gotoPay(LevyPaymentFlow levyPaymentFlow, LevyMerchantRelationDTO levyMerchantRelation) {
log.info("httpInvokeLevyApi 调用服务商api下发 mq异步实现 消息入队...
Object[] objects = {levyPaymentFlow, levyMerchantRelation, Thread.currentThread().getName()};
rabbitTemplate.convertAndSend(exchangeName, queueName, objects);
}
}

消费端,则是使用Listener监听队列消息,进行消费。

package com.emax.channel.provider.modules.mq;

import org.springframework.stereotype.Component;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;

/**
* 调用服务商api下发 mq异步实现
* @date 2022-9-20 21:22
*/
@Component
@Slf4j
public class LevyPayApiInvokerMqConsumer {

@RabbitHandler
@RabbitListener(queues = "${mq-brokers.levy_pay_api_invoker_queue}")
public void onMessage(Object[] objects) throws Exception {
LevyPaymentFlow levyPaymentFlow = (LevyPaymentFlow) objects[0];
LevyMerchantRelationDTO levyMerchantRelation = (LevyMerchantRelationDTO) objects[1];
Thread.currentThread().setName(String.valueOf(objects[2]).concat("_mq"));
log.info("httpInvokeLevyApi 调用服务商api下发 mq异步实现 消息出队...
long nowTime = System.currentTimeMillis();

// 执行逻辑
try {
// redisLimiter.limitWait("httpInvokeLevyApi", 5, 1);
levyPaymentAsyncService.gotoPay(levyPaymentFlow, levyMerchantRelation);
} finally {
log.info("httpInvokeLevyApi 调用服务商api下发 mq异步实现 duration={}", System.currentTimeMillis() - nowTime);
}
}
}

 

 

Rabbitmq代码可读、可维护性挺高

zhenghe-channel项目工程庞大,package包和类文件很多,将broker的声明和使用分放在不同的类里,不易读。 这次呢,为了代码易读和易维护,我将声明broker的Bean和生产者代码、消费者代码写在一个类里。必须棒棒哒~(。≧3≦)ノ⌒☆

Object[] objects = {levyPaymentFlow, levyMerchantRelation, Thread.currentThread().getName()};
rabbitTemplate.convertAndSend(exchangeName, queueName, objects);
}

@RabbitHandler

public void onMessage(Object[] objects) throws Exception {
LevyPaymentFlow levyPaymentFlow = (LevyPaymentFlow) objects[0];

levyPaymentAsyncService.gotoPay(levyPaymentFlow, levyMerchantRelation);
} finally {
log.info("httpInvokeLevyApi 调用服务商api下发 mq异步实现 duration={}", System.currentTimeMillis() - nowTime);
}

}
}
