【摘要】 前言
Routing模式通过routingKey，决定发送和接收路径架构如下：

Routing模式通过routingKey，决定发送和接收路径架构如下：

代码
- build.gradle
plugins { id 'java'
}
group 'com.nick'
version '1.0-SNAPSHOT'
sourceCompatibility = 1.8
repositories { mavenCentral()
}
dependencies { testCompile group: 'junit', name: 'junit', version: '4.12' compile group: 'com.rabbitmq', name: 'amqp-client', version: '5.2.0' compile group: 'org.slf4j', name: 'slf4j-api', version: '1.7.25' compile group: 'org.slf4j', name: 'slf4j-simple', version: '1.7.25' compile group: 'org.projectlombok', name: 'lombok', version: '1.18.0'
}
- ReceiveLogsDirect.java
package com.nick.Routing;
import com.rabbitmq.client.*;
import java.io.IOException;
public class ReceiveLogsDirect { private static final String EXCHANGE_NAME = "direct_logs"; public static void main(String[] argv) throws Exception { ConnectionFactory factory = new ConnectionFactory(); factory.setHost("192.168.5.136"); Connection connection = factory.newConnection(); Channel channel = connection.createChannel(); channel.exchangeDeclare(EXCHANGE_NAME, "direct"); String queueName = channel.queueDeclare().getQueue(); channel.queueBind(queueName, EXCHANGE_NAME, "ERROR"); channel.queueBind(queueName, EXCHANGE_NAME, "INFO"); System.out.println(" [*] Waiting for messages. To exit press CTRL+C"); Consumer consumer = new DefaultConsumer(channel) { @Override public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException { String message = new String(body, "UTF-8"); System.out.println(" [x] Received '" + envelope.getRoutingKey() + "':'" + message + "'"); } }; channel.basicConsume(queueName, true, consumer); }
}
- EmitDebugLogDirect.java
package com.nick.Routing;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
import java.util.concurrent.TimeoutException;
public class EmitDebugLogDirect { private static final String EXCHANGE_NAME = "direct_logs"; public static void main(String[] argv) throws java.io.IOException, TimeoutException { ConnectionFactory factory = new ConnectionFactory(); factory.setHost("192.168.5.136"); Connection connection = factory.newConnection(); Channel channel = connection.createChannel(); channel.exchangeDeclare(EXCHANGE_NAME, "direct"); String severity = "DEBUG"; String message = "debug message"; channel.basicPublish(EXCHANGE_NAME, severity, null, message.getBytes()); System.out.println(" [x] Sent '" + severity + "':'" + message + "'"); channel.close(); connection.close(); }
}
- EmitErrorLogDirect.java
package com.nick.Routing;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
import java.util.concurrent.TimeoutException;
public class EmitErrorLogDirect { private static final String EXCHANGE_NAME = "direct_logs"; public static void main(String[] argv) throws java.io.IOException, TimeoutException { ConnectionFactory factory = new ConnectionFactory(); factory.setHost("192.168.5.136"); Connection connection = factory.newConnection(); Channel channel = connection.createChannel(); channel.exchangeDeclare(EXCHANGE_NAME, "direct"); String severity = "ERROR"; String message = "error message"; channel.basicPublish(EXCHANGE_NAME, severity, null, message.getBytes()); System.out.println(" [x] Sent '" + severity + "':'" + message + "'"); channel.close(); connection.close(); }
}
测试
- 先执行接收；
- 分别执行发送debug和error;
- 在接收窗口上可以看到error消息有收到，debug接收不到；
