消息发布和订阅

交换机设置

public class RabbitSend {
    
    public static void main(String[] args) throws IOException, TimeoutException, InterruptedException {
        
        Connection connection = RabbitMQ.getConnection();

        channel.close();
        
        connection.close();
        
    }
    
}

消费者

public class RabbitGetmsg {
    
    public static void main(String[] args) throws IOException, TimeoutException {
        Connection connection = RabbitMQ.getConnection();
        
        Channel channel = connection.createChannel();

        boolean ack = false;//自动应答
        channel.basicConsume(RabbitMQ.SMS_NAME, ack, consumer);
        
    }

配置路由

        channel.exchangeDeclare(RabbitMQ.EXCHANGE_NAME2, "direct");
        String routingKey = "info";
        channel.basicPublish(RabbitMQ.EXCHANGE_NAME2, routingKey, null, msg.getBytes());

消费者配置路由可以配置多个

        String routingKey = "error";
        channel.queueBind(RabbitMQ.EMAIL_NAME2, RabbitMQ.EXCHANGE_NAME2, routingKey);
        channel.queueBind(RabbitMQ.EMAIL_NAME2, RabbitMQ.EXCHANGE_NAME2, "info");
        channel.queueBind(RabbitMQ.EMAIL_NAME2, RabbitMQ.EXCHANGE_NAME2, "warning");

topic模式

生产者

 channel.exchangeDeclare(RabbitMQ.EXCHANGE_NAME2, "topic");

 channel.queueBind(RabbitMQ.EMAIL_NAME2, RabbitMQ.EXCHANGE_NAME2, "warning.strength");

消费者  ( #代表匹配所有 *代表一个)

channel.queueBind(RabbitMQ.EMAIL_NAME2, RabbitMQ.EXCHANGE_NAME2, "warning.#");

channel.queueBind(RabbitMQ.EMAIL_NAME2, RabbitMQ.EXCHANGE_NAME2, "warning.strength");
