我正在使用2个Weblogic数据源;在我的XML配置中,我有2个持久性单元,2个entityManagerFactories和2个transactionManagers.文件如下：
persistence.xml中：
<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文件：
<!-- 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" />

</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-->

<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> {}
有关处理多个事务管理器的正确注释的任何建议吗？我错过了别的什么吗？其他堆栈溢出示例使用DAO,我没有找到帮助,因为我使用的是存储库,模型和控制器java文件.我也没有使用hibernate,很多例子都参考了hibernate.非常感谢您的见解.
我收到以下错误：

解决方法:
您可以使用：
@Transactional("transactionManagerName")
请参阅org.springframework.transaction.annotation.Transactional(@Transactional)注释javadoc：
/**
* 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 "";
