消息队列解析Message

消息队列生产者

@Autowired
private final AmqpTemplate amqpTemplate;

public void test() {
    Map<String, Object> testMap = Maps.newHashMap();
    testMap.put("userId", 101);
    testMap.put("archiveId",202);
    amqpTemplate.convertSendAndReceive("testQueue",testMap);
}

消息队列消费者

import cn.hutool.core.bean.BeanUtil;
import java.util.Map;
import lombok.extern.slf4j.Slf4j;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.messaging.Message;
import org.springframework.stereotype.Component;


@Component
@Slf4j
public class RabbitQueueListener {

    /**
     * 监听 testQueue 队列的处理器
     * @param message
     */
    @RabbitListener(queues = "testQueue")
    @RabbitHandler
    public void onMessage(Message message) {

        Map<String, Object> map = BeanUtil.beanToMap(message.getPayload());
        log.info("消费端Payload: " + map);
    }
}

使用BeanUtil.beanToMap()方法将message.getPayload()转成Map

结果：消费端Payload: {userId=101, archiveId=202}
