在订阅模式的基础上制定一些特定发送规则
创建路由模式的生产者：
注意这些变化，跟之前的订阅模式并不一样
package cn.dzz.routineQueueInProducer; import com.rabbitmq.client.BuiltinExchangeType; import com.rabbitmq.client.Channel; import com.rabbitmq.client.Connection; import com.rabbitmq.client.ConnectionFactory; import java.nio.charset.StandardCharsets; public class RoutineInProducer { public static void main(String[] args) throws Exception{ ConnectionFactory connectionFactory = new ConnectionFactory(); connectionFactory.setHost("192.168.2.121"); connectionFactory.setPort(ConnectionFactory.DEFAULT_AMQP_PORT); // 5672 connectionFactory.setVirtualHost("/dzz"); // 虚拟主机？ 默认值 / connectionFactory.setUsername("test"); // guest connectionFactory.setPassword("123456"); // guest Connection connection = connectionFactory.newConnection(); Channel channel = connection.createChannel(); /** * 多了一个创建交换机的过程 * public DeclareOk exchangeDeclare(String exchange, BuiltinExchangeType type, boolean durable, boolean autoDelete, boolean internal, Map<String, Object> arguments) throws IOException { * return this.exchangeDeclare(exchange, type.getType(), durable, autoDelete, internal, arguments); * } * String exchange 交换机名称 * String type 交换机类型，这里换成枚举类型，方便查找 com.rabbitmq.client.BuiltinExchangeType * DIRECT("direct"), 定向 简单模式 和 工作模式 * FANOUT("fanout"), 扇形 广播（通知给所有和这个交换机绑定的队列） * TOPIC("topic"), 通配符 ？ * HEADERS("headers"); 参数匹配， 视频暂不讲解 * boolean durable 持久化 * boolean autoDelete 自动删除 * boolean internal 内部使用 一般false * Map<String, Object> arguments */ String exchangeName = "test_routine"; channel.exchangeDeclare( exchangeName, BuiltinExchangeType.DIRECT, true, false, false, null ); String queueName1 = "routine - exchange - 1"; String queueName2 = "routine - exchange - 2"; channel.queueDeclare(queueName1, true, false, false, null); channel.queueDeclare(queueName2, true, false, false, null); /** * 将交换机和队列绑定 * public com.rabbitmq.client.AMQP.Queue.BindOk queueBind(String queue, String exchange, String routingKey) throws IOException { * return this.queueBind(queue, exchange, routingKey, (Map)null); * } * String queue 队列名称 * String exchange 交换机名称 * String routingKey 路由键，绑定规则 * 如果是fanout模式， 设置""即可，默认就是给所有队列绑定 * */ channel.queueBind(queueName1, exchangeName, "error"); channel.queueBind(queueName2, exchangeName, "info"); channel.queueBind(queueName2, exchangeName, "warning"); channel.queueBind(queueName2, exchangeName, "error"); // 发送消息 这里制定一些不同的消息 以做出区分 String level = "info"; for (int i = 0; i < 10; i++) { if (i == 4) level = "warning"; else if (i == 7) level = "error"; String body = "sending routine msg " + i + level; channel.basicPublish(exchangeName, level, null, body.getBytes(StandardCharsets.UTF_8)); } // 释放资源 channel.close(); connection.close(); } }
发送到队列之后可以查看队列面板
可以看到队列1 只有3条消息，队列2有10条消息
我们再创建对应的消费者（1 和 2）打印查看
消费和之前的模式一致，只是需要找到对应的队列名称来进行消费
package cn.dzz.routineQueue; import com.rabbitmq.client.*; import java.io.IOException; import java.nio.charset.StandardCharsets; public class RoutineQueueInConsumer2 { /** * 工作队列 消费者 * @param args */ public static void main(String[] args) throws Exception{ ConnectionFactory connectionFactory = new ConnectionFactory(); connectionFactory.setHost("192.168.2.121"); connectionFactory.setPort(ConnectionFactory.DEFAULT_AMQP_PORT); // 5672 connectionFactory.setVirtualHost("/dzz"); // 虚拟主机？ 默认值 / connectionFactory.setUsername("test"); // guest connectionFactory.setPassword("123456"); // guest Connection connection = connectionFactory.newConnection(); Channel channel = connection.createChannel(); // 声明将不在需要 // channel.queueDeclare("work_queue", true, false, false, null); // 从生产者复制过来需要的队列名称 String queueName1 = "routine - exchange - 1"; String queueName2 = "routine - exchange - 2"; Consumer consumer = new DefaultConsumer(channel) { @Override public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException { System.out.println("body(message) " + new String(body, StandardCharsets.UTF_8)); System.out.println("- - - - - over - - - - -"); } }; channel.basicConsume(queueName2, true, consumer); } }
