org.springframework.messaging.converter.MessageConversionException：找不到从实际有效负载类型“ byte []”到预期有效负载的转换器

编程问答 2022-06-08

问题描述

我有一个spring boot应用程序，在配置类中使用@EnableJMS在侦听器类中使用@JMSListener

在配置类中，我创建了一个用于连接Factory的bean和一个用于消息转换器的bean

类似这样的东西：

@Bean // Serialize message content to json using TextMessage
  public MessageConverter jacksonJmsMessageConverter() {
    MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
    converter.settargettype(MessageType.TEXT);
    converter.setTypeIdPropertyName("_type");
    return converter;
  }

我的侦听器类如下：

@Component
public class Receiver {

  @JmsListener(destination = "abcqueue",containerFactory = "myFactory")
  public void receiveMessage(Message<MyModel> mymodel) {
    System.out.println("Received <");
  }

}

错误消息：
