No qualification bean of type [org.springframework.transaction.PlatformTransactionManager] defined

I use 2 Weblogic data sources; In my XML configurations, I have 2 save units, 2 entityManagerFactories, and 2 transaction statements. Files are as follows:

persistence.xml

<persistence-unit name="modelPersistence" transaction-type="RESOURCE_LOCAL"> <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> </persistence-unit> <persistence-unit name="orderPersistence" transaction-type="RESOURCE_LOCAL"> <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> </persistence-unit>

config.xml

 <!-- transactionManagers --> <tx:annotation-driven transaction-manager="transactionManager" /> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <bean id="transactionManagerLegacy" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactoryLegacy" /> </bean> <!-- entityManagerFactory --> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="dataSourceModel"/> <property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml" /> <property name="persistenceUnitName" value="modelPersistence" /> <property name="jpaProperties"> <props> <prop key="eclipselink.logging.level">FINE</prop> </props> </property> <property name="loadTimeWeaver"> <bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/> </property> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter"> <property name="databasePlatform" value="org.eclipse.persistence.platform.database.OraclePlatform" /> <property name="generateDdl" value="true"/> <property name="showSql" value="true"/> </bean> </property> </bean> <!-- entityManagerFactoryLegacy --> <bean id="entityManagerFactoryLegacy" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="dataSourceOrder"/> <property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml" /> <property name="persistenceUnitName" value="orderPersistence" /> <property name="jpaProperties"> <props> <prop key="eclipselink.logging.level">FINE</prop> </props> </property> <property name="loadTimeWeaver"> <bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/> </property> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter"> <property name="databasePlatform" value="org.eclipse.persistence.platform.database.OraclePlatform" /> <property name="generateDdl" value="true"/> <property name="showSql" value="true"/> </bean> </property> </bean> <!-- data source 1--> <bean id="dataSourceModel" class="org.springframework.jndi.JndiObjectFactoryBean" depends-on="model-datasource-jndi"> <property name="jndiName" ref="model-datasource-jndi" /> <property name="resourceRef" value="true" /> </bean> <!-- data source 2--> <bean id="dataSourceOrder" class="org.springframework.jndi.JndiObjectFactoryBean" depends-on="order-datasource-jndi"> <property name="jndiName" ref="order-datasource-jndi" /> <property name="resourceRef" value="true" /> </bean> <!-- configure persistenceUnitManager --> <bean id="persistenceUnitManager" class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager"> <property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml" /> <property name="dataSources"> <map> <entry key="jdbc/MODEL-DS" value-ref="dataSourceModel"/> <entry key="jdbc/ORDER-DS" value-ref="dataSourceOrder"/> </map> </property> </bean> <jpa:repositories base-package="org.codingpedia.demo.repositories.ModelRepository" entity-manager-factory-ref="entityManagerFactory" transaction-manager-ref="transactionManager"/> <jpa:repositories base-package="org.codingpedia.demo.repositories.OrderRepository" entity-manager-factory-ref="entityManagerFactoryLegacy" transaction-manager-ref="transactionManagerLegacy"/>

ModelRepository

 @Repository ("ModelRepo") @PersistenceContext(unitName = "modelPersistence") public interface ModelRepository extends JpaRepository<Model, String> {}

orderRepository

 @Repository ("OrderRepo") @PersistenceContext(unitName = "orderPersistence") public interface OrderRepository extends JpaRepository<Model, String> {}

Any suggestions for proper annotation to handle multiple transaction managers? Did I miss something? Other examples use DAOs, which I did not find useful, since I use java repository, model, and controller files. I also do not use sleep mode, which is also mentioned in a few examples. Your understanding is greatly appreciated.

I get the following error:

You can use:

 @Transactional("transactionManagerName")

See org.springframework.transaction.annotation.Transactional (@Transactional) javadoc annotation:

 /** * A qualifier value for the specified transaction. * <p>May be used to determine the target transaction manager, * matching the qualifier value (or the bean name) of a specific * {@link org.springframework.transaction.PlatformTransactionManager} * bean definition. */ String value() default "";

In your case, it should be:

 <tx:annotation-driven transaction-manager="transactionManager" /> <tx:annotation-driven transaction-manager="transactionManagerLegacy" />

call the identifier of your beans.

If you need multiple data sources, I suggest reading this: http://www.baeldung.com/spring-data-jpa-multiple-databases

Dali currently only supports one Persistence Unit and one Persistence XML file for each project. Other configurations may exist in the JPA project, but validation and default processing may not be correct when using multiple duration units. Read more here .
