profile.xml 中相关配置

mq.address=xxxx
mq.exchange=xxxxx
mq.routingKey=xxx
mq.queue=xxx
mq.port=5672
mq.user=xxxx
mq.pwd=xxxx
mq.timeout=5000
mq.vhost=lms

相关类文件

public class RmqProducer {
    private static final Logger LOGGER = LoggerFactory.getLogger(RmqConsumer.class);

    private RabbitTemplate rabbitTemplate;

    /**
     * 发送信息
     */
    public void sendMessage(RabbitMessage msg) {
        try {
            // 发送信息
            rabbitTemplate.convertAndSend(msg);
        } catch (Exception e) {
            LOGGER.error("rmq消费者任务处理出现异常", e);
        }
    }

    public void setRabbitTemplate(RabbitTemplate rabbitTemplate) {
        this.rabbitTemplate = rabbitTemplate;
    }
}

public class RmqConsumer {
    private static final Logger LOGGER = LoggerFactory.getLogger(RmqConsumer.class);

    public void rmqConsumeMessage(Object obj) {
        LOGGER.info("rmq 消费者任务:{}", JSON.toJSONString(obj));
        // TODO 具体的消费策略
    }
}

使用

• 使用时只需要注入相应的bean即可使用
• 如果有多个队列，注意以下Bean的定义
1. rmqProducer
2. rmqConsumer
3. messageListenerAdapter
4. LisetenerContainer

备注

• 如果已经在rabbit的图形化界面bind相关的exchange 和 quene，橙色斜体加粗子部分可以省略；
