Mit Feder-Integration, Bean Erstellungsreihenfolge

Question

Ich habe drei Kanäle. + hinzugefügt Konfigurationsklasse Signatur

@Configuration 
@EnableIntegration 
@PropertySource({ "..." }) 
@ComponentScan(basePackages = "...") 
public class HttpIntegrationConfig { 
    @Bean(name = "requestChannel") 
    public DirectChannel requestChannel() { 
     return new DirectChannel(); 
    } 

    @Bean(name = "responseChannel") 
    public DirectChannel responseChannel() { 
     return new DirectChannel(); 
    } 

    @Bean(name = "replyChannel") 
    public QueueChannel replyChannel() { 
     return new QueueChannel(); 
    } 

    ... 

Ich möchte meine benutzerdefinierte Service-Klasse injizieren. So ... + hinzugefügt findAll Methode

@Service 
public class ServiceMessagingGatewayService { 

    ... 

    @Autowired 
    DirectChannel requestChannel; 

    @Autowired 
    QueueChannel replyChannel; 

    public Object findAll() { 
     Message message = RestfulMessageBuilder.build(new Object(), "services"); 

     requestChannel.send(message); 

     Message<?> received = replyChannel.receive(); 

     return received.getPayload(); 
    } 

    ... 
} 

Aber diese Injektion Ursache Folge Ausnahme:

Wie oben Nachrichten, Frühling Kontext hat keine Bohnen gegen sie. Was?! Also habe ich einen Code geändert, der sich auf Injektionen bezieht.

@Autowired 
@Lazy 
DirectChannel requestChannel; 

@Autowired 
@Lazy 
QueueChannel replyChannel; 

Es ist nicht OK, weil die Eigenschaft 'dataTypes' des Kanals null ist. Es verursacht NullReferenceException. So ...

DirectChannel requestChannel = (DirectChannel)applicationContext.getBean("requestChannel"); 
QueueChannel replyChannel = (QueueChannel)applicationContext.getBean("replyChannel"); 

Es ist Ok. Keine Ausnahmen. Es läuft gut. Aber was ich wirklich wissen möchte ist, warum @Autowired in meinem Fall NoSuchBeanDefinitionException verursacht?

Answer 1

Bitte teilen Sie mehr StackTrace zu diesem Thema.

Sieht aus wie Ihre ServiceMessagingGatewayService wird sehr früh von einigen BeanPostProcessor abgeholt.

Von anderer Seite wäre es besser, mit uns einige kleinere Anwendung mit dem Problem zu teilen, um von unserer Seite zu spielen.

Nichts offensichtlich jetzt. Entschuldigung ...

Answer 2

Es ist vollständig meine Schuld.

Ich habe @CompnentScan auf einige wenige Konfigurationsklassen angewendet. Unter ihnen gibt es einen doppelten Paketpfad. Das verursacht das Chaos wie oben.

Ich habe sie nur definiert, dann finde ich Ruhe.

Danke Artem Bilan für hilfreicher Hinweis.
