我已经用实体管理器配置了两个持久性单元，如下所示：

<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"/>

我最初只有一个配置，它被称为“
transactionManager”。Addint一个附加的持久性单元似乎会生成错误。我不明白的一件事，如果我配置了两个持久性单元（每个持久性单元用于一个单独的数据库），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，找不到在任何地方有“ transactionManager”引用的地方）

我在Jpa / Hibernate中使用Spring。
