SpringBoot中如何监听两个不同源的RabbitMQ消息队列

spring-boot如何配置监听两个不同的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；

详细步骤：

1. application.properties 文件配置：

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：为第一个MQ的配置，后面简称UMQ 
b.rabbitmq：为第二个MQ的配置，后面简称BMQ

2. RabbitMqConfig中读取配置信息

@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中配置链接

@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标签指若不指定链接，默认选择链接，在配置了多个链接必须添加@Primary标签，否则有可能会找不到对应的rabbitMQ的连接。

4.配置监听连接

@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.配置消息代理服务器

@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.具体监听队列及使用配置

UMQ队列queue监听配置

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

RMQ队列queue监听配置

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