Ne peut pas convertir une valeur de type [com.soleil.proxy.$Proxy32 ScopedObject

Je suis à l'aide de spring batch, ci-dessous sont les configurations.

<beans:bean id="symfonyJob" class="com.st.symfony.Symfony"
    p:dir="${symfony.dir}" p:consolePath="${symfony.console.path}"
    p:strUtil-ref="strUtil" p:logFilePath="${batch.log.file.path}.#{jobParameters[batch_id]}" scope="step"/>


<beans:bean id="importExchangesItemWriter"
    class="com.st.batch.foundation.ImportExchangesItemWriter"
    p:symfony-ref="symfonyJob" p:replyTimeout="${import.exchanges.reply.timeout}" scope="step"/>

<beans:bean id="importExchangesFileItemReader"
    class="org.springframework.batch.item.file.MultiThreadedFlatFileItemReader"
    p:resource="file:${spring.tmp.batch.dir}/#{jobParameters[batch_id]}/exchanges.txt"
    p:lineMapper-ref="stLineMapper" p:startAt="#{stepExecutionContext['startAt']}"
    p:maxItemCount="#{stepExecutionContext['itemsCount']}" scope="step" />

<step id="importExchangesStep">
    <tasklet transaction-manager="transactionManager">
        <chunk reader="importExchangesFileItemReader" writer="importExchangesItemWriter"
            commit-interval="${import.exchanges.commit.interval}" />
    </tasklet>
</step>

<job id="importExchangesJob" restartable="true">

    <step id="importExchangesStep.master">
        <partition partitioner="importExchangesPartitioner"
            handler="importExchangesPartitionHandler" />
    </step>

</job>

Tout fonctionnait avant que je change le champ d'application de symfonyJob et importExchangesItemWriter à portée="étape". Dès que j'ai changé de cadre, je suis

Il travaillait même si le lecteur avait portée étape, mais dès que je l'ajoute à l'écrivain, j'ai commencé à faire cette erreur.

Avez-vous arriver à trouver une solution pour cela ?
La solution pour moi a été d'utiliser l'interface, pas le de béton de classe, au sein de ma réception de classe. Voir @Jim Ford répondre

J'ai vu cette erreur avec un peu différente scénario:

Je n'ai pas suivi le modèle approprié pour HibernateDAO bean, il est nécessaire d'interface avec les méthodes et passer le type d'interface au service de la couche de printemps bean comme des biens au lieu de les DAO de mise en œuvre de la classe.

applicationContext.xml

<bean id="myEntityDAO" class="com.me.etc.MyEntityDAOImpl" parent="hibernateDAO"/>
<bean id="myEntityService class="com.me.etc.MyEntityServiceImpl">
<property name="myEntityDAO" ref="myEntityDAO" />
</bean>

MyEntityServiceImpl.java

class MyEntityServiceImpl extends MyEntityService {
.
.
.
//I got the error when I had this property of class MyEntityDAOImpl
private MyEntityDAOInterface myEntityDAO;
//changed the setter as well to match
@Required
public setMyEntityDAO(MyEntityDAOInterface myEntityDAO) {
this.myEntityDAO = myEntityDAO;
}
.
.
.
}

Printemps voulu l'interface pour transmettre, au lieu de la mise en œuvre de fichier de classe qui a causé le "Ne peut pas convertir une valeur de type" erreur.

Vous devez exposer <aop:scoped-proxy proxy-target-class="true" /> pour symfonyJob bean parce que la norme de proxy création d'exposer des interfaces et non pas de la réalité de la classe (comme vous en avez besoin,parce que ImportExchangesItemWriter.setSymfony() accepter - pour sûr - un com.st.symfony.Symfony paramètre et non pas une interface).

Vous pouvez avoir plus d'informations sur la création de proxy mécanismes de googler "aop proxytargetclass".

La création de l'interface et la modification de la propriété type d'Interface de type travaillé en . Merci
