【问题描述】：

以下是我的 applicationContext.xml

<bean
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
    id="entityManagerFactory2">
    <property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.m3.xml" />
    <property name="persistenceUnitName" value="M3tables" />
    <property name="packagesToScan" value="com.foo.webapp.integration.model.m3" />
</bean>

<bean
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
    id="entityManagerFactory1">
    <property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml" />
    <property name="persistenceUnitName" value="webApp-integration" />
    <property name="packagesToScan" value="com.foo.webapp.integration.model.test" />
</bean>
<!-- ##################################### -->

<!-- Transaction Manager -->
<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager1">
    <property name="entityManagerFactory" ref="entityManagerFactory1" />
</bean>

<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager2">
    <property name="entityManagerFactory" ref="entityManagerFactory2" />
</bean>
<tx:annotation-driven mode="aspectj"
    transaction-manager="transactionManager1" />
<tx:annotation-driven mode="aspectj"
    transaction-manager="transactionManager2" />

<jpa:repositories base-package="com.foo.webapp.test.repository"
    entity-manager-factory-ref="entityManagerFactory1" />

<jpa:repositories base-package="com.foo.webapp.repository"
    entity-manager-factory-ref="entityManagerFactory2" />

在我的服务文件中，我通过两种方式添加了事务管理器

1 .通过添加类级别

@Service
@Transactional(value="transactionManager2")
public class MitmasServiceImpl implements MitmasService {
    @Override
    public List<Mitmas> getAllItem() 
    {
        return mitmasRepository.findAll();

    }
}

通过在方法层添加事务

@Service
public class MitmasServiceImpl implements MitmasService 
{
    @Override
    @Transactional(value="transactionManager2")
    public List<Mitmas> getAllItem() 
    {
        return mitmasRepository.findAll();

    }
}

我的完整服务文件如下

@Service
@Transactional(value="transactionManager2")
public class MitmasServiceImpl implements MitmasService {

    @Autowired
    private MitmasRepository mitmasRepository ;

    @Override
    @Transactional(value="transactionManager2")
    public Mitmas createItem(Mitmas Mitmas) 
    {
        return mitmasRepository.save(Mitmas);
    }

    @Override
    @Transactional(value="transactionManager2",rollbackFor=ItemNotFound.class)
    public Mitmas deleteItem(String itemNo) throws ItemNotFound 
    {
        Mitmas deleteItem = mitmasRepository.findOne(itemNo);
        if(deleteItem == null)
        {
            throw new ItemNotFound();
        }
        else
        {
            mitmasRepository.delete(itemNo);
        }
        return deleteItem;
    }

    @Override
    @Transactional(value="transactionManager2",rollbackFor=ItemNotFound.class)
    public Mitmas updateItem(Mitmas Mitmas) throws ItemNotFound 
    {   
        Mitmas updateItem = mitmasRepository.findOne(Mitmas.getMmitno());

        if(updateItem==null)
        {
            throw new ItemNotFound() ;
        }

        updateItem.setMmitds(Mitmas.getMmitds());
        updateItem.setMmfuds(Mitmas.getMmfuds());

        return updateItem;
    }


    @Override
    @Transactional(value="transactionManager2")
    public List<Mitmas> getAllItem() 
    {
        return mitmasRepository.findAll();

    }


}

但我收到以下错误

谁能帮我解决这个问题

【问题讨论】：

你在某个地方有一个 @Transactional 没有值属性，这意味着 @Transactional("transactionManager")。您应该有一个BeanCreationException，NoSuchBeanDefinitionException 是其根本原因
作为补充，你只需要一个<tx:annotation-driven />，基本上你的第一个是没用的，因为第二个会覆盖它。
@orid ，我已经检查了我的服务文件，并且它具有 @Transactional(value="transactionManager2") 的所有方法。仍然抛出相同的异常
@M.Deinum 感谢您提供的信息，但我仍然面临问题
您正在使用 Spring Data JPA，并且这些存储库使用默认 @Transactional 进行注释。您将需要多个 configrue 2 spring jpa 块并指定要使用的事务管理器和实体管理器（您可能已经有一个与 entitymanager 添加事务管理器）。

标签： java spring hibernate spring-data-jpa

【解决方案1】：

如前所述，您正在使用 Spring Data JPA 和多个 EntityManagerFactory bean。您需要告诉 Spring Data JPA 哪个 EntityManagerFactory 和 PlatformTransactionManager 用于该特定配置。如果你不指定它会尝试使用默认的transactionManager。这在 Spring Data JPA 参考指南中的 here 中有解释。

请注意，如果没有明确定义 transaction-manager-ref，我们需要一个名为 transactionManager 的 PlatformTransactionManager bean。

你的配置

<jpa:repositories base-package="com.foo.webapp.test.repository"
    entity-manager-factory-ref="entityManagerFactory1" />

<jpa:repositories base-package="com.foo.webapp.repository"
    entity-manager-factory-ref="entityManagerFactory2" />

您只指定了entity-manager-factory-ref 而不是transaction-manager-ref，因此它试图找到一个名为transactionManager 的PlatformTransactionManager。

要修复将适当的transaction-manager-ref 添加到元素。

<jpa:repositories base-package="com.foo.webapp.test.repository"
    entity-manager-factory-ref="entityManagerFactory1" 
    transaction-manager-ref="transactionManager1" />

<jpa:repositories base-package="com.foo.webapp.repository"
    entity-manager-factory-ref="entityManagerFactory2" 
    transaction-manager-ref="transactionManager2" />
