Utilisation de Bean à partir d'un autre module

Question

Je crée une application Batch pour mettre certaines données d'un service Web sur la base de données. Pour cela, j'ai besoin de convertir les DTO reçus par le web-service en classes utilisables. Ceci est possible en utilisant un mappeur défini dans un autre module.

Lorsque j'ai essayé @Autowierd le mappeur j'ai une exception et je ne trouve pas comment s'évanouir.

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jobConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.execution.batch.processor.UtilisateurProcessor com.execution.batch.jobConfiguration.JobConfigurationAbstract.utilisateurProcessor; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'utilisateurProcessor': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.execution.server.common.mapper.UtilisateurMapper com.execution.batch.processor.UtilisateurProcessor.utilisateurMapper; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.execution.server.common.mapper.UtilisateurMapper] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Les mappeurs fonctionnent correctement dans leur module. Je peux @Autowierdd et l'utiliser sans problèmes. Et mon lot fonctionne bien si je ne @Autowierd le mappeur.

Quelqu'un a une idée?

Merci!

EDIT

Ma configuration est sur ma classe de configuration d'emploi:

@Configuration 
@EnableBatchProcessing 
@ComponentScan(basePackages = {"com.execution.batch"}) 

J'ai essayé de mettre: @ComponentScan(basePackages = {"com.execution.batch", "com.execution.serve"})

Mais si je que j'ai erreurs signalées à l'injection de le haricot du travail:

Comme je l'ai dit, séparément les modules fonctionnent bien. Lorsque je scanne le serveur et le module de traitement par lots, le balayage du lot ne fonctionne pas.

• Lorsque je numérise uniquement le module de traitement par lots, le module serveur ne fonctionne pas car je ne pense pas qu'il soit numérisé.

Answer 1

Je suppose que vous avez oublié de définir le "scanner" avec le package approprié de la classe que vous voulez.

Votre haricot est utilisateurProcessor, fqn est com.execution.batch.processor.UtilisateurProcessor. Est-il configuré comme @Component ou dans votre XML?

Veuillez coller la config de printemps, pour voir si vous avez ajouté com.execution.server.common.mapper au scanner de Spring.

Answer 2

Étant donné que vos configurations fonctionnent indépendamment, il existe un bon changement que vous avez des noms contradictoires dans les deux paquets. Ce qui pourrait entraîner l'écrasement des configurations ou des beans.

E.g.

package com.x; 
@Configuration 
public class AConfiguration { 
} 

package com.y; 
@Configuration 
public class AConfiguration { 
} 

En tant que nom de bean dans springcontext, seul le nom de la classe est utilisé sans le package. Ainsi, si vous scannez les deux paquets, seule une classe de configuration sera réellement traitée. La même chose est également valable pour les classes annotées avec @Component.

Il est important de comprendre que les classes @Component et @Configuration sont également instanciées en tant que beans, avec le nom de classe simple en tant que nom de bean.

Les méthodes annotées @Bean sont également une source potentielle d'erreurs. Si vous avez le même nom de méthode dans deux Configuration-Beans différents, un seul sera instancié.

De plus, si vous utilisez comme @bean methodname le même nom qu'un nom de classe @Configuration, l'un est remplacé par l'autre.
