java - websystique - spring mvc+hibernate+maven crud operations example

No se define ningún bean llamado ''transactionManager''

Question

He configurado dos unidades persistentes con los administradores de entidades configurados como se muestra a continuación:

<bean id="liveEntityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
p:dataSource-ref="LiveDataSource">
<property name="persistenceUnitName" value="LivePersistenceUnit" />
</bean>
<bean id="archiveEntityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
p:dataSource-ref="ArchiveDataSource">
<property name="persistenceUnitName" value="ArchivePersistenceUnit" />
</bean>

Luego configuré los administradores de transacciones como

 <bean id="LiveTransactionManager"
class="org.springframework.orm.jpa.JpaTransactionManager"
p:entityManagerFactory-ref="liveEntityManagerFactory"/>
<bean id="ArchiveTransactionManager"
class="org.springframework.orm.jpa.JpaTransactionManager"
p:entityManagerFactory-ref="archiveEntityManagerFactory"/>

Originalmente tenía solo uno configurado y se llamaba "transactionManager". Addint una unidad persistente adicional parece generar un error. Una cosa que no entiendo, si configuré dos unidades persistentes (cada una para una base de datos separada) ¿también necesito configurar un administrador de entidades individuales y un administrador de transacciones para cada fuente de datos?

El error que recibo se muestra a continuación: (busqué todos los archivos y no puedo encontrarlos en ninguna parte donde haya una referencia para "transactionManager")

Estoy usando Spring con Jpa / Hibernate.

Gracias

Answer 1

El valor predeterminado para el atributo transaction-manager es transaction-manager. En su caso, debe especificar qué administrador de transacciones desea usar por método o servicio de esta manera:

@Service
@Transactional(value="LiveTransactionManager")
class someClass...

o

@Transactional(value="ArchiveTransactionManager")
public void someMethod

Answer 2

En realidad, hay una forma de utilizar el nombre de TransactionManager con Spring Data JPA. Esto funciona para mí:

<bean id="myTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="myEntityManagerFactory" />
</bean>
<tx:annotation-driven transaction-manager="myTransactionManager"/>
<jpa:repositories base-package="com.xxx.yyy" entity-manager-factory-ref="myEntityManagerFactory" transaction-manager-ref="myTransactionManager">
</jpa:repositories>
