[英]When transactionManager is not named "transactionManager"
I am trying Spring 3(.0.2.RELEASE) and JPA2 and Hibernate 3.5.1-Final... One thing upsets me is that spring seems only accept a transaction Manager named "transactionManager"我正在尝试 Spring 3(.0.2.RELEASE) 和 JPA2 以及 Hibernate 3.5.1-Final... 让我感到不安的是 spring 似乎只接受名为“transactionManager”的事务管理器
If I don't name it "transactionManager", Spring will throws NoSuchBeanDefinitionException: No bean named 'transactionManager' is defined.如果我不将其命名为“transactionManager”,Spring 将抛出NoSuchBeanDefinitionException:未定义名为“transactionManager”的 bean 。
Here is my config:这是我的配置:
<context:component-scan base-package="destiny.data.mining"/>
<context:annotation-config/>
<bean id="miningEntityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="mining"/>
</bean>
<bean id="miningTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager" >
<property name="entityManagerFactory" ref="miningEntityManagerFactory"/>
</bean>
<tx:advice id="txAdviceMining" transaction-manager="miningTransactionManager">
<tx:attributes>
<tx:method name="get*" read-only="true"/>
<tx:method name="save*" propagation="REQUIRED"/>
<tx:method name="update*" propagation="REQUIRED"/>
<tx:method name="delete*" propagation="REQUIRED"/>
<tx:method name="*" propagation="SUPPORTS" read-only="true"/>
</tx:attributes>
</tx:advice>
<aop:config>
<aop:pointcut id="methods" expression="execution(* destiny.utils.AbstractDao+.*(..))"/>
<aop:advisor advice-ref="txAdviceMining" pointcut-ref="methods"/>
</aop:config>
<tx:annotation-driven transaction-manager="miningTransactionManager"/>
In this config, an Entity Manager Factory is not necessarily named "entityManagerFactory", and "txAdvice" is not necessarily named "txAdvice", either.在此配置中,实体管理器工厂不一定命名为“entityManagerFactory”,“txAdvice”也不一定命名为“txAdvice”。 But I don't know why on earth Spring requires a transaction manager named "transactionManager"?
但我不知道为什么Spring需要一个名为“transactionManager”的事务管理器?
Is there any way not to name a transaction manager "transactionManager"?有没有办法不将事务管理器命名为“transactionManager”? (I'm running multiple spring config files, so I try my best to avoid name-conflicting)
(我正在运行多个 spring 配置文件,所以我尽力避免名称冲突)
test code:测试代码:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:mining.xml"})
public class MiningPersonDaoTest
{
@Inject
private EntityManagerFactory miningEntityManagerFactory;
@Inject
private MiningPersonDao miningPersonDao;
@Transactional
@Test
public void testUpdate()
{
MiningPerson p = miningPersonDao.get(42L);
p.setLocationName("OOXX");
miningPersonDao.update(p);
System.out.println(p);
}
}
My understanding is that in the context of unit tests ( TransactionalTestExecutionListener
), the code that otherwise looks up the transaction manager is not used (
TransactionInterceptor#determineTransactionManager
). 我的理解是,在单元测试(
TransactionalTestExecutionListener
)的上下文中, 不使用以其他方式查找事务管理器的代码( TransactionInterceptor#determineTransactionManager
)。
You could try to annotate your test class with @TransactionConfiguration
, which accepts a transactionManager
attribute. 您可以尝试使用
@TransactionConfiguration
注释您的测试类,它接受transactionManager
属性。 Not the most elegant way, but possibly the best option for the time being. 不是最优雅的方式,但可能是目前最好的选择。
Today, I ran into same issue when I was trying very trivial example of Spring-Data JPA. 今天,当我尝试Spring-Data JPA的非常简单的例子时,我遇到了同样的问题。 I had given custom name to transaction manager, "dmTransactionManager".
我给事务管理器“dmTransactionManager”提供了自定义名称。 To fix it I had to specify it, I had to specify it like below:
要解决它我必须指定它,我必须指定如下:
<jpa:repositories base-package="com.my.repository" transaction-manager-ref="dmTransactionManager"/>
From the following doc: https://docs.spring.io/spring-framework/docs/current/reference/html/data-access.html#transaction-declarative-annotations来自以下文档: https://docs.spring.io/spring-framework/docs/current/reference/html/data-access.html#transaction-declarative-annotations
You can omit the transaction-manager attribute in the <tx:annotation-driven/> tag if the bean name of the TransactionManager that you want to wire in has the name transactionManager.
如果要连接的 TransactionManager 的 bean 名称名为 transactionManager,则可以省略 <tx:annotation-driven/> 标记中的 transaction-manager 属性。 If the TransactionManager bean that you want to dependency-inject has any other name, you have to use the transaction-manager attribute
如果要依赖注入的 TransactionManager bean 有任何其他名称,则必须使用 transaction-manager 属性
