RabbitMQ工作模式——Routing路由模式

1.Routing路由模式

在这里插入图片描述
Routing生产者代码

public class Producer_Routing {public static void main(String[] args) throws IOException, TimeoutException {//1.创建连接工厂ConnectionFactory factory = new ConnectionFactory();//2.设置参数factory.setHost("172.16.98.133"); ip 默认值 localhostfactory.setPort(5672);//端口 默认值5672factory.setVirtualHost("/itcast");//虚拟机 默认值factory.setUsername("heima");//用户名 默认guestfactory.setPassword("heima");//密码 默认值 guest//3.创建连接 ConnectionConnection connection = factory.newConnection();//4.创建ChannelChannel channel = connection.creatChannel();/*exchange(String exchange,String type,boolean durable,boolean autoDelete,boolean internal,Map<String,Object> arguments)参数：1.exchange:交换机名称2.type：交换机类型DIRECT("direct")，:定向FANOUT("fanout")，：扇形（广播）发送消息到每一个与之绑定的队列TOPIC("topic")，：通配符方式HEADERS("headers");：参数匹配3.durable：是否持久化4.autoDelete：自动删除5.internal：内部使用。一般为false6.arguments：参数，一般设为null*///5.创建交换机String exchangeName = "test_direct";channel.exchangeDeclare(exchangeName,BuiltinExchangeType.DIRECT,true,false,false,null);//6.创建队列String queue1Name = "test_direct_queue1";String queue2Name = "test_direct_queue2";channel.queueDeclare(queue1Name,true,false,false,null);channel.queueDeclare(queue2Name,true,false,false,null);//7.绑定队列和交换机/*queueBind(String queue,String exchange,String routingKey)参数：1.queue:队列名称2.exchange:交换机名称3.routingKey:路由键，绑定规则如果交换机的类型为：fanout，routingKey设置为空字符串*///队列1的绑定 errorchannel.queueBind(queue1Name,exchangeName,"error");//队列2的绑定 info error warningchannel.queueBind(queue2Name,exchangeName,"info");channel.queueBind(queue2Name,exchangeName,"error");channel.queueBind(queue2Name,exchangeName,"warning");//8.发送消息String body = "日志信息，张三调用了findAll方法...日志级别：info...";	channel.basicPublish(exchangeName,"info",null,body.getBytes());//9.释放资源channel.close();connection.close();}
}

Routing1消费者代码

public class Consumer_Routing1 {public static void main(String[] args) throws IOException, TimeoutException {//1.创建连接工厂ConnectionFactory factory = new ConnectionFactory();//2.设置参数factory.setHost("172.16.98.133"); ip 默认值 localhostfactory.setPort(5672);//端口 默认值5672factory.setVirtualHost("/itcast");//虚拟机 默认值factory.setUsername("heima");//用户名 默认guestfactory.setPassword("heima");//密码 默认值 guest//3.创建连接 ConnectionConnection connection = factory.newConnection();//4.创建ChannelChannel channel = connection.creatChannel();String queue1Name = "test_direct_queue1";String queue2Name = "test_direct_queue2";/*basicConsume(String queue,boolean autoAck,Consumer callback)参数：1.queue：队列名称2.autoAck：是否自动确认3.callback：回调对象*///接收消息Consumer consumer = new DefaultConsumer(channel){/*回调方法，当收到消息后会自动执行该方法1.consumerTag：标识2.envelope：获取一些信息，交换机，路由key...3.properties：配置信息4.body：数据*/@Overridepublic void handleDelivery(String consumerTag,Envelope envelope,AMQP.BasicProperties properties,byte[] body){System.out.println("consumerTag" + consumerTag);System.out.println("Exchange" + envelope.getExchange());System.out.println("RoutingKey" + envelope.getRoutingKey());System.out.println("properties" + properties);System.out.println("body" + new String(body));System.out.println("将日志信息存储到数据库......");}};channel.basicConsume("queue2Name",true,consumer);//消费者不能关闭资源}
}

Routing2消费者代码

public class Consumer_Routing2 {public static void main(String[] args) throws IOException, TimeoutException {//1.创建连接工厂ConnectionFactory factory = new ConnectionFactory();//2.设置参数factory.setHost("172.16.98.133"); ip 默认值 localhostfactory.setPort(5672);//端口 默认值5672factory.setVirtualHost("/itcast");//虚拟机 默认值factory.setUsername("heima");//用户名 默认guestfactory.setPassword("heima");//密码 默认值 guest//3.创建连接 ConnectionConnection connection = factory.newConnection();//4.创建ChannelChannel channel = connection.creatChannel();String queue1Name = "test_direct_queue1";String queue2Name = "test_direct_queue2";/*basicConsume(String queue,boolean autoAck,Consumer callback)参数：1.queue：队列名称2.autoAck：是否自动确认3.callback：回调对象*///接收消息Consumer consumer = new DefaultConsumer(channel){/*回调方法，当收到消息后会自动执行该方法1.consumerTag：标识2.envelope：获取一些信息，交换机，路由key...3.properties：配置信息4.body：数据*/@Overridepublic void handleDelivery(String consumerTag,Envelope envelope,AMQP.BasicProperties properties,byte[] body){System.out.println("consumerTag" + consumerTag);System.out.println("Exchange" + envelope.getExchange());System.out.println("RoutingKey" + envelope.getRoutingKey());System.out.println("properties" + properties);System.out.println("body" + new String(body));System.out.println("将日志信息打印到控制台......");}};channel.basicConsume("queue1Name",true,consumer);//消费者不能关闭资源}
