  • RabbitMQ之交换机及spring整合

    交换机

    交换机属性:

    Name:交换机名称

    Type:交换机类型 directtopicfanoutheaders

    Durability:是否需要持久化,true为持久化

    Auto Delete:当最后一个绑定到Exchange上的队列删除后,自动删除该Exchange

    Internal:当前Exchange是否用于RabbitMQ内部使用,默认为False

    Arguments:扩展参数,用于扩展AMQP协议,定制化使用

    直流交换机

    直连交换机Direct Exchange(完全匹配路由key

    所有发送到Direct Exchange的消息会被转发到RouteKey中指定的Queue

    注意:Direct模式可以使用RabbitMQ自带的Exchangedefault Exchange,所以不需要将Exchange进行任何绑定(binding)操作,消息传递时,RouteKey必须完全匹配才会被队列接收,否则该消息会被抛弃;

            channel.basicPublish(exchangeName, routingKey , null , msg.getBytes());
    
        }
    }

    主题交换机

    主题交换机Topic Exchange(匹配路由规则的交换机)

    所有发送到Topic Exchange的消息被转发到所有关系RouteKey中指定TopicQueue上;

    ExchangeRouteKey和某Topic进行模糊匹配,此时队列需要绑定一个Topic

    注意:可以使用通配符进行模糊匹配

    符号:#” 匹配一个或者多个词

    符号:*” 匹配不多不少一个词

    列如:

    log.#” 能够匹配到 “log.info.oa

    log.*” 能够匹配到 “log.err

    输出交换机

    输出交换机Fanout Exchange(不做路由)

    不处理路由键,只需要简单的将队列绑定到交换机上;

    发送到交换机的消息都会被转发到与该交换机绑定的所有队列上;

    Fanout交换机转发消息是最快的

    Binding-绑定

    Exchange和Exchange、Queue之间的连接关系;
    Binding中可以包含RoutingKey或者参数

    Queue-消息队列

    消息队列,实际存储消息数据
    Durability:是否持久化
    Durable:是,Transient:否
    Auto delete:如选yes,代表当最后一个监听被移除之后,该Queue会自动被删除

    Message-消息

    服务器和应用程序之间传递的数据
    本质上就是一段数据,由Properties和Payload(Body)组成
    常用属性:delivery model、headers(自定义属性)
    
    
    Message-其他属性
    content_type、content_encoding、priority
    correlation_id、reply_to、expiration、message_id
    Timestamp、type、user_id、app_id、cluster_id

    Virtual host-虚拟主机

    虚拟地址,用于进行逻辑隔离,最上层的消息路由
    一个Virtual Host里面可以有若干个Exchange和Queue
    同一个Virtual Host里面不能有相同名称的Exchange或Queue

    RabbitMQ整合 SpringCloud实战

    注意一点,在发送消息的时候对template进行配置mandatory=true保证监听有效

    生产端还可以配置其他属性,比如发送重试,超时时间、次数、间隔等

    消费端核心配置

    u 首先配置手工确认模式,用于ACK的手工处理,这样我们可以保证消息的可靠性送达,或者在消费端消费失败的时候可以做到重回队列、根据业务记录日志等处理

    u 可以设置消费端的监听个数和最大个数,用于控制消费端的并发情况

    @RabbitListener注解的使用

    消费端监听@RabbitListener注解,这个对于在实际工作中非常的好用

    u @RabbitListener是一个组合注解,里面可以注解配置(@QueueBinding@Queue@Exchange)直接通过这个组合注解一次性搞定消费端交换机、队列、绑定、路由、并且配置监听功能

    注:由于类配置写在代码里非常不友好,所以强烈建议大家使用配置文件配置
