java - Spring Integration Bridge 注解配置导致 BeanCurrentlyInCreationException

Question

当我尝试连接配置类上的 channel 时，出现 BeanCurrentlyInCreationException 异常。 我只是指Documentation这里。 如果我理解有误，请指正。 我使用 spring-integration 5.0.7.RELEASE 在我的应用程序上进行了以下配置。

@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());
   }

}

刚刚在MyIntegrationConfiguration配置类上创建了两个 channel

@Configuration
@IntegrationComponentScan
@EnableIntegration
public class MyIntegrationConfiguration {

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

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

}

我这里有 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());

 }
}

我收到异常消息请求的bean当前正在创建

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 类自身上，它就可以正常工作。 谢谢。

Answer 1

感谢您分享一个好的示例!好吧，我已将其复制为框架本身中的测试用例，看起来像您在单独扫描的 @Configuration< 中遇到 @BridgeFrom("GWChannel") 的问题 类。当您将其移动到应用程序中时，它就开始工作。

请就此事提出 JIRA，我们将解决:我知道我们可以对此事做些什么。
