我已经配置了两个持久性单元，实体管理器设置如下：
<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>
然后我将事务管理器配置为
<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"/>
我最初只配置了一个，它被称为“transactionManager”。 Addint一个额外的持久单元似乎会产生错误。有一点我不明白，如果我配置了两个持久性单元（每个用于一个单独的数据库），我是否还需要为每个数据源配置一个单独的实体管理器和一个事务管理器？
我得到的错误如下所示:(我搜索了所有文件，我找不到任何有“transactionManager”参考的地方）

我正在使用Spring和Jpa / Hibernate。
谢谢
transaction-manager属性的默认值是transaction-manager。在您的情况下，您应该为每个方法或服务指定要使用的事务管理器，如下所示：
@Service
@Transactional(value="LiveTransactionManager")
class someClass...
要么
@Transactional(value="ArchiveTransactionManager")
public void someMethod
实际上，有一种方法可以将命名的TransactionManager与Spring Data JPA一起使用。这对我有用：
<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>
我使用java配置并指定transactionManagerRef是我的解决方案：
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
entityManagerFactoryRef = "myCustomEntityManagerFactory",
basePackages = {"ua.demitt.other.path.to.repos"},
transactionManagerRef = "myCustomTransactionManager" )
