【RabbitMQ】04 路由模式
作者：互联网
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);
}
}
消费者1打印
