Rabbitmq的五种模式和案例

消息生产者p将消息放入队列

消费者监听队列,如果队列中有消息,就消费掉,消息被拿走后,自动从队列删除

(缺点:消息可能没有被消费者正确处理,已经消失了,无法恢复)

应用场景:聊天室

1.引入依赖

<dependencies>
  <dependency>
    <groupId>com.rabbitmq</groupId>
    <artifactId>amqp-client</artifactId>
    <version>3.4.1</version>
  </dependency>
  <dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.7.7</version>
  </dependency>
  <dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-lang3</artifactId>
    <version>3.3.2</version>
  </dependency>

  <dependency>
    <groupId>org.springframework.amqp</groupId>
    <artifactId>spring-rabbit</artifactId>
    <version>1.4.0.RELEASE</version>
  </dependency>
  <dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
  </dependency>
</dependencies>
2.创建链接工具类

3.生产者

4.消费者
