Spring Integration Bridge注释配置导致BeanCurrentlyInCreationException

标签： java spring spring-boot spring-integration

当我尝试连接配置类上的通道时，我得到BeanCurrentlyInCreationException。 我只是在这里指Documentation。 如果我误解了，请纠正我。 使用spring-integration 5.0.7.RELEASE在我的应用程序上进行以下配置。

@SpringBootApplication
@ComponentScan
public class Application {

public static void main(String[] args) {
    ApplicationContext context = SpringApplication.run(Application.class, args);

    OrderGateway gateway = context.getBean(OrderGateway.class);

    //just emitting 1 to 1000 message to the channel
    gateway.send(MessageBuilder
                 .withPayload(IntStream.range(1, 1000)
                             .mapToObj(i -> i)
                             .collect(Collectors.toList())).build());
   }

}

并刚刚在MyIntegrationConfiguration配置类上创建了两个频道

@Configuration
@IntegrationComponentScan
@EnableIntegration
public class MyIntegrationConfiguration {

 @Bean
 public DirectChannel GWChannel() {
     return new DirectChannel();
 }

 @Bean
 @BridgeFrom("GWChannel")
 public DirectChannel outputChannel() {
     return new DirectChannel();
 }

}

我在这里有ServiceActivator来记录消息

@MessageEndpoint
public class MessageActivatorImpl {

 @ServiceActivator(inputChannel = "outputChannel")
 public void receiveMessage(Message<Integer> message) {

    System.out.println("message = " + message.getPayload());

 }
}

我说“ Requested bean is currently in creation”异常

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'messageActivatorImpl' defined in file [D:\tmp\integration\target\classes\com\test\mnr\MessageActivatorImpl.class]: Initialization of bean failed; nested exception is org.springframework.messaging.core.DestinationResolutionException: A bean definition with name 'outputChannel' exists, but failed to be created; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myIntegrationConfiguration' defined in file [D:\tmp\integration\target\classes\com\test\mnr\MyIntegrationConfiguration.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'outputChannel': Requested bean is currently in creation: Is there an unresolvable circular reference?

那么spring配置有什么问题吗？如果我将所有配置放在Application类本身上，就可以正常工作。  谢谢。

1 个答案:

答案 0 :(得分：1)

感谢您分享一个好的样本！好吧，我已经在框架本身中将其作为测试用例进行了重现，看起来像是在单独的扫描@BridgeFrom("GWChannel")类中有@Configuration的问题。当您将其移至Application时，它便开始工作。

请提出关于此事的JIRA，我们将解决：我知道我们可以在此事上做些什么。
