The role of configuration configuration class, rabbitMq code example how to customize beans
@Configuration @ConditionalOnClass(SimpleRabbitListenerContainerFactory.class) public class ConsumerConfig { @Value(“${rabbit.batch.num:100}”) private int batchNum; @Bean(“batchQueueRabbitListenerContainerFactory”) public SimpleRabbitListenerContainerFactory batchQueueRabbitListenerContainerFactory(ConnectionFactory connectionFactory) { SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory(); factory.setConnectionFactory(connectionFactory); factory.setBatchListener(true); factory.setConsumerBatchEnabled(true); factory.setBatchSize(batchNum); return factory; } } This code is a RabbitMQ message consumer configuration class based on Spring Boot. Let me explain step by step and give examples: @Configuration: This annotation indicates […]

RabbitMQ related deployment
1. Common cluster preparation environment Note that these three servers are all connected, and the RabbitMQ cluster nodes must be in the same segment. If they are connected across domains, the effect will be worse. 10.36.192.150 rabbitmq-1 10.36.192.151 rabbitmq-2 10.36.192.152 rabbitmq-3 All three servers have their firewalls and selinux turned off [root@rabbitmq-1 ~]#systemctl stop firewalld […]
5.RabbitMQ release confirmation advanced
5 Release Confirmation Advanced Due to some unknown reasons in the production environment, rabbitMQ restarted. During the restart of RabbitMQ, the producer failed to deliver messages, resulting in message loss, which required manual processing and reply. So we tried to think about how to achieve reliable delivery of RabbitMQ. Especially in extreme situations. When the […]
