Question

我发现Spring数据1.6.0的奇怪行为（降级版本1.5.2没有这个问题）。看来这个版本严格要求实体管理器工厂bean的id为＆＃34; entityManagerFactory＆＃34;。如果没有，运行TestNG测试时会出现此错误：

引起：org.springframework.beans.factory.BeanCreationException：创建名称为＆＃39; jpaMapppingContext的bean时出错＆＃39;：无法创建内部bean＆＃39;（内部bean）＃36b87404＆＃39;类型为[org.springframework.orm.jpa.SharedEntityManagerCreator]时设置bean属性＆＃39; entityManager＆＃39 ;;嵌套异常是org.springframework.beans.factory.BeanCreationException：创建名为＆＃39;（内部bean）的bean时出错＃36b87404＆＃39;：无法解析对bean的引用＆＃39; entityManagerFactory＆＃39;设置构造函数参数时;嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有bean命名为＆＃39; entityManagerFactory＆＃39;已定义

我的配置是：

<!-- ************************************************************** -->

    <bean id="entityManagerFactoryCustomId"

        <property name="password" value="${jdbc.password}" />
        <!-- Pool properties -->

        <property name="maxPoolSize" value="${pool.maxsize}" />
        <property name="initialPoolSize" value="${pool.initialPoolSize}" />
        <property name="maxStatements" value="${pool.maxstatements}" />

    </bean>

    <!-- JPA transaction manager -->
    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">

    </bean>

  <!-- Activate Spring Data JPA repository support -->
    <jpa:repositories base-package="pds.archiva.db.repository" />
</code>

它是Spring Data JPA中的错误还是我做错了什么？在Windows java 64bit 7u55上测试，版本如下：

spring.framework.version = 4.0.5.RELEASE
spring.security.version = 3.2.4.RELEASE
spring.data-jpa.version = 1.6.0.RELEASE

正如我所写，同样的测试仅适用于更改spring.data-jpa.version = 1.5.2.RELEASE ...或将bean的id更改为＆＃34; entityManagerFactory＆＃34;而不是＆＃34; entityManagerFactoryCustomId＆＃34;。

刚刚添加了@StéphaneNicoll答案：然后显式设置实体管理器（请参阅jpa：repositories中的entity-manager-factory-refelement。看起来文档可能已过时。
