RabbitMq 在 Spring 引导微服务中看不到队列并且无法将消息从一个服务发送到另一个服务

Question

I have a problem about sending message from advertisement service to report service through RabbitMq .

I run the rabbitmq through docker . Here is the code shown below.

rabbitmq:
    image: "rabbitmq:3-management"
    container_name: "rmq3"
    environment:
      RABBITMQ_DEFAULT_USER: "rabbitmq"
      RABBITMQ_DEFAULT_PASS: "123456"
    ports:
      - "5672:5672"
      - "15672:15672"

When I tried to get message from rabbitTemplate.convertAndSend in advertisement service . I got an error in report service .

Here is the error shown below.

Caused by: org.springframework.messaging.converter.MessageConversionException: Cannot convert from [[B] to [com.springbootmicroservices.report.dto.AdvertisementDto] for GenericMessage [payload=byte[59], headers={amqp_receivedDeliveryMode=PERSISTENT, amqp_receivedRoutingKey=queue-advertisement, amqp_contentEncoding=UTF-8, amqp_deliveryTag=1, amqp_consumerQueue=queue-advertisement, amqp_redelivered=false, id=38ab4c7f-6de4-dbbd-6471-5ba1cf2a80bc, amqp_consumerTag=amq.ctag-d4XUFeupnFO59f5OKRwlTQ, amqp_lastInBatch=false, contentType=application/json, __TypeId__=com.springbootmicroservices.advertisement.dto.AdvertisementDto, timestamp=1659551606120}]

How can I fix the issue?

Answer 1

After I defined both this bean in advertisement and report service, the issue disappeared.

Here is the bean

@Bean
public MessageConverter jsonMessageConverter(ObjectMapper objectMapper) {
   return new Jackson2JsonMessageConverter(objectMapper);
}
