使用Spring Data JPA,Hibernate和多个事务管理器:没有定义名为'transactionManager'的bean

Question

编辑:对于可能对此问题感兴趣的任何人,我在问题的最后提供了相关解决方案的问题分析.

我正在为Web应用程序配置模块,其中我使用的是Spring 3.2,Hibernate 4.1,Spring Data JPA 1.3和Apache CXF 2.5(特别是JAX-RS模块).我有以下配置(工作完全正常,为简明起见,省略了详细信息):

  @Bean(name = "entityManagerFactory")
  public LocalContainerEntityManagerFactoryBean getEntityManagerFactory() throws SQLException{
    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
    //...    
    return factory;
  }

  @Bean(name = "transactionManager")
  public JpaTransactionManager getTransactionManager() throws SQLException{
    JpaTransactionManager manager = new JpaTransactionManager();
    //...    
    return manager;
  }

  @Bean(name = "persistenceExceptionTranslator")
  public PersistenceExceptionTranslator getPersistenceExceptionTranslator(){
    return new HibernateExceptionTranslator();
  }

我的问题是我必须依赖一些定义自己的外部模块PlatformTransactionManager,所以我发现自己同时使用更多的事务管理器.Transactional.html #value()可以很容易地解决这个问题,所以无论我需要在哪里使用@Transactional,我都要使用我必须用于该事务的事务管理器的名称来限定注释.
我想将我在模块中定义的事务管理器的名称更改为更有意义的名称,以满足外部模块的标准.因此,例如,externalModule1将其经理定义为externalModule1TransactionManager我想要的

  @Bean(name = "myModuleransactionManager")
  public JpaTransactionManager getTransactionManager() throws SQLException{
    JpaTransactionManager manager = new JpaTransactionManager();
    //...    
    return manager;
  }

这似乎很容易,不幸的是,当我做这个改变时(我改变了相应的用法,@Transactional#value()我得到了一个例外.

特别是,我想集中注意力

myModule.package.SomeOtherClass.someOtherMethod(SomeClass.java:114)

和

myModule.package.SomeClass.someMethod(SomeClass.java:64)

他们的代码看起来像

@Transactional("myModuleransactionManager")
public ... someOtherMethod(){
   ...
}

和

public ... someMethod(){
   ...
}

所以,根据我的理解,这个配置应该有效,为什么会抛出这个异常呢？是否需要标准的命名事务管理器？或者它是由cxf引起的？我发现同样的应用程序(内涉及多个事务管理的一些问题例如1,例2),但在这些问题接受的答案开车到我的解决方案.我误解了什么,我做错了什么？
感谢所有愿意阅读这个长期问题的人,直到这里!

编辑提供基于Michail答案的完整解释:使用Spring Data JPA,需要定义存储库接口以连接到数据库.someOtherMethod确实在调用我的一个存储库,定义为:

@Repository("myRepository")
@Transactional(propagation = Propagation.NESTED, value = "myModuleransactionManager")
public interface MyRepository extends JpaRepository<MyEntity, Integer>
{

}

这看起来很好,但是查看JpaRepository实现源代码(所以,看着org.springframework.data.jpa.repository.support.SimpleJpaRepository我发现save(以及其他更新方法)注释了@Transactional.代码来自SimpleJpaRepository

    @Transactional
    public <S extends T> S save(S entity) {

        if (entityInformation.isNew(entity)) {
            em.persist(entity);
            return entity;
        } else {
            return em.merge(entity);
        }
    }

因此,在使用Spring Data JPA时,必须使用缺省事务管理器(名为transactionManager).对我的目标不好,但至少我现在知道就是这样!

Answer 1

看起来你的someOtherMethod调用任何其他@Transactional组件(一些类与save方法).我认为它有@Transactinal()(空)注释(使用默认bean命名transactionManager).

您可能会TransactionInterceptor在stacktrace中看到2个位置.请提供一些有关它的细节.

Answer 2

我怀疑您只需要确保您的存储库在@EnableJpaRepositories批注中使用正确命名的事务管理器即可。

即

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
        entityManagerFactoryRef = "fooEntityManagerFactory", 
        transactionManagerRef = "fooTransactionManager",
        basePackages = {"com.sctrcd.multidsdemo.integration.repositories.foo"})
public class FooConfig {
    //...
}

我花了一些时间来弄清细节，因此我在这里提供了关于如何配置Spring Data JPA存储库以与多个数据源一起使用的完整说明：

xml配置中有多个jpa：repositories，如何使用Spring Java配置与@EnableJPARepositories配置？
