一个简单的java程序，用于RabbitMQ日志监控

RabbitMQ的所有日志，都会发给topic类型的exchange “amq.rabbitmq.log”  routingKey 有 debug,info,waring,error.  如果接收所有类型日志，可以用 #

package logs;

import java.io.IOException;
import java.util.concurrent.TimeoutException;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.DefaultConsumer;
import com.rabbitmq.client.Envelope;
import com.rabbitmq.client.AMQP.BasicProperties;

import utils.ChannelUtils;

public class ListenerRabbitMQLogs {

    private static final String QUEUE_NAME_DEBUG = "queue_debug";
    private static final String QUEUE_NAME_INFO = "queue_info";
    private static final String QUEUE_NAME_WARNING = "queue_warning";
    private static final String QUEUE_NAME_ERROR = "queue_error";

    private static final String EXCHANGE_NAME_LOG = "amq.rabbitmq.log";

    public static void main(String[] args) throws IOException, TimeoutException {

        Connection connection = ChannelUtils.getConnection("ListenerLog");

        Channel channelDebug = connection.createChannel();
        Channel channelInfo = connection.createChannel();
        Channel channelWarning = connection.createChannel();
        Channel channelError = connection.createChannel();

        channelDebug.queueDelete(QUEUE_NAME_DEBUG);
        channelDebug.queueDeclare(QUEUE_NAME_DEBUG, false, false, false, null);

        channelInfo.queueDelete(QUEUE_NAME_INFO);
        channelInfo.queueDeclare(QUEUE_NAME_INFO, false, false, false, null);

        channelWarning.queueDelete(QUEUE_NAME_WARNING);
        channelWarning.queueDeclare(QUEUE_NAME_WARNING, false, false, false, null);

        channelError.queueDelete(QUEUE_NAME_ERROR);
        channelError.queueDeclare(QUEUE_NAME_ERROR, false, false, false, null);

        channelDebug.queueBind(QUEUE_NAME_DEBUG, EXCHANGE_NAME_LOG, "debug");
        channelInfo.queueBind(QUEUE_NAME_INFO, EXCHANGE_NAME_LOG, "info");
        channelWarning.queueBind(QUEUE_NAME_WARNING, EXCHANGE_NAME_LOG, "warning");
        channelError.queueBind(QUEUE_NAME_ERROR, EXCHANGE_NAME_LOG, "error");

        channelDebug.basicConsume(QUEUE_NAME_DEBUG, new LogsConsumer(channelDebug,"Debug"));
        channelInfo.basicConsume(QUEUE_NAME_INFO, new LogsConsumer(channelInfo,"Info"));
        channelWarning.basicConsume(QUEUE_NAME_WARNING, new LogsConsumer(channelWarning,"Warning"));
        channelError.basicConsume(QUEUE_NAME_ERROR, new LogsConsumer(channelError,"Error"));

    }

}

class LogsConsumer extends DefaultConsumer {

    private String logLevel;

    public LogsConsumer(Channel channel,String logLevel) {
        super(channel);
        this.logLevel = logLevel;
    }

    @Override
    public void handleDelivery(String consumerTag, Envelope envelope, BasicProperties properties, byte[] body)
            throws IOException {

        System.out.println(logLevel+":"+new String(body));

        // 使用手动确认模式，这里需要确认收到消息。
        getChannel().basicAck(envelope.getDeliveryTag(), false);
    }

}
