RabbitMQ多线程配置和异常解决办法

（1）RabbitMQ多线程配置

RabbitMqConfig.java

@Bean("customContainerFactory")

public SimpleRabbitListenerContainerFactory containerFactory(SimpleRabbitListenerContainerFactoryConfigurer configurer,

ConnectionFactory connectionFactory) {

SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();

factory.setConcurrentConsumers(10); // 设置线程数

factory.setMaxConcurrentConsumers(10); // 最大线程数

configurer.configure(factory, connectionFactory);

return factory;

}

XxxListener.java

@RabbitListener(queues = "xxx", containerFactory = "customContainerFactory")

（2）inequivalent arg 'x-max-length' for queue 'xxx' in vhost '/': received none but current is the value '200000' of type 'long'，异常解决办法

RabbitMqConfig.java

@Bean

public Queue xxx() {

Map<String, Object> args = new HashMap<String, Object>();

args.put("x-max-length", 200000);

return new Queue("xxx", true, false, false, args);

}
