How spring-boot configuration monitor two different RabbitMQ

由于前段时间在公司开发过程中碰到了一个问题，需要同时监听两个不同的rabbitMq，但是之前没有同时监听两个RabbitMq的情况，因此在同事的帮助下，成功实现了监听多个MQ。下面我给大家一步一步讲解下，也为自己做个笔记；

detailed steps:

1. application.properties configuration file:

u.rabbitmq.addresses=10.0.0.1:5672 u.rabbitmq.username=username1 u.rabbitmq.password=password1 u.rabbitmq.vhost.provider=/provider b.rabbitmq.addresses=10.0.0.2:5672 b.rabbitmq.username=username2 b.rabbitmq.password=password1 b.rabbitmq.vhost.provider=/provider

u.rabbitmq: MQ configuration for the first, later referred UMQ 
b.rabbitmq: MQ configuration for the second, later referred BMQ

2. RabbitMqConfig reads configuration information

@Value("${u.rabbitmq.username}")
private String uname;
@Value("${u.rabbitmq.password}") private String upassword; @Value("${u.rabbitmq.vhost.provider}") private String uhost; @Value("${u.rabbitmq.addresses}") private String uaddress; @Value("${b.rabbitmq.username}") private String bname; @Value("${b.rabbitmq.password}") private String bpassword; @Value("${b.rabbitmq.vhost.provider}") private String bhost; @Value("${b.rabbitmq.addresses}") private String baddress;

3.RabbitMqConfig configure link

@Bean(name="uConnectFactory")
@Primary
public ConnectionFactory uConnectFactory() { CachingConnectionFactory connectionFactory = new CachingConnectionFactory(); connectionFactory.setAddresses(uaddress); connectionFactory.setUsername(uname); connectionFactory.setPassword(upassword); connectionFactory.setVirtualHost(uhost); return connectionFactory; } @Bean(name="bConnectFactory") public ConnectionFactory bConnectFactory() { CachingConnectionFactory connectionFactory = new CachingConnectionFactory(); connectionFactory.setAddresses(rpbaddress); connectionFactory.setUsername(rpbusername); connectionFactory.setPassword(rpbpassword); connectionFactory.setVirtualHost(rpbvhost); return connectionFactory; }

@Primary label refers without specifying a link, the link is selected by default, it is configured with multiple link must add @Primary label, or they might not find the connection corresponding rabbitMQ.

4. monitor connector configuration

@Bean(name="uRabbitListenerContainerFactory")
public SimpleRabbitListenerContainerFactory uRabbitListenerContainerFactory(
        @Qualifier("uConnectFactory") ConnectionFactory connectionFactory,
        RabbitProperties config
) {
    SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
    factory.setConnectionFactory(connectionFactory); RabbitProperties.Listener listenerConfig = config.getListener(); factory.setAutoStartup(listenerConfig.isAutoStartup()); if (listenerConfig.getAcknowledgeMode() != null) { factory.setAcknowledgeMode(listenerConfig.getAcknowledgeMode()); } if (listenerConfig.getConcurrency() != null) { factory.setConcurrentConsumers(listenerConfig.getConcurrency()); } if (listenerConfig.getMaxConcurrency() != null) { factory.setMaxConcurrentConsumers(listenerConfig.getMaxConcurrency()); } if (listenerConfig.getPrefetch() != null) { factory.setPrefetchCount(listenerConfig.getPrefetch()); } if (listenerConfig.getTransactionSize() != null) { factory.setTxSize(listenerConfig.getTransactionSize()); } return factory; } @Bean(name="bRabbitListenerContainerFactory") public SimpleRabbitListenerContainerFactory brabbitListenerContainerFactory( @Qualifier("bConnectionFactory") ConnectionFactory connectionFactory, RabbitProperties config ) { SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory(); factory.setConnectionFactory(connectionFactory); RabbitProperties.Listener listenerConfig = config.getListener(); factory.setAutoStartup(listenerConfig.isAutoStartup()); if (listenerConfig.getAcknowledgeMode() != null) { factory.setAcknowledgeMode(listenerConfig.getAcknowledgeMode()); } if (listenerConfig.getConcurrency() != null) { factory.setConcurrentConsumers(listenerConfig.getConcurrency()); } if (listenerConfig.getMaxConcurrency() != null) { factory.setMaxConcurrentConsumers(listenerConfig.getMaxConcurrency()); } if (listenerConfig.getPrefetch() != null) { factory.setPrefetchCount(listenerConfig.getPrefetch()); } if (listenerConfig.getTransactionSize() != null) { factory.setTxSize(listenerConfig.getTransactionSize()); } return factory; }

5. Configure Message Proxy

@Bean(name="uAmqpAdmin")
public AmqpAdmin amqpAdmin(@Qualifier("uConnectFactory") ConnectionFactory connectionFactory) { RabbitAdmin admin = new RabbitAdmin(connectionFactory); admin.setAutoStartup(false); return admin; } @Bean(name="bAmqpAdmin") public AmqpAdmin rpdAmqpAdmin(@Qualifier("bConnectionFactory") ConnectionFactory connectionFactory) { RabbitAdmin admin = new RabbitAdmin(connectionFactory); admin.setAutoStartup(false); return admin; }

6. DETAILED monitor queue and a use configuration

UMQ queue queue monitor configuration

    @RabbitListener(queues = "queue", containerFactory = uRabbitListenerContainerFactory")
     public void handleMessage(String message) throws Exception {
    具体操作。。。。
 }

RMQ queue queue monitor configuration

@RabbitListener(queues = "queue", containerFactory = rRabbitListenerContainerFactory")
    public void handleMessage(String message) throws Exception {
    具体操作。。。。
}
