java - 如何将 @EnableTransactionManagement 与 StaticMethodMatcherPointcutAdvisor 结合使用

Question

给定以下服务:

public interface MyService {
    void method();
}

它的实现:

@Service
public class MyServiceImpl implements MyService {

    @Transactional
    @CustomAnnotation
    @Override
    public void method() {
        ...
    }
}

我想按以下方式使用 StaticMethodMatcherPointcutAdvisor:

public class MyPointcutAdvisor extends StaticMethodMatcherPointcutAdvisor {
   ...

    @Override       
    public boolean matches(Method method, Class targetClass) {
       Method m = method;
       if(annotationPresent(method)) {
           return true;
       }
       Class<?> userClass = ClassUtils.getUserClass(targetClass);
       Method specificMethod = ClassUtils.getMostSpecificMethod(method, userClass);
       specificMethod = BridgeMethodResolver.findBridgedMethod(specificMethod);
       if(annotationPresent(specificMethod )) {
           return true;
       }
       return false;
    }
    ...
}

问题在于 Spring 使用 InfrastructuralAdvisorAutoProxyCreator 创建该类的代理，而 DefaultAdvisorAutoProxyCreator 将为 MyPointcutAdvisor 创建代理，但 MyPointcutAdvisor 仅将代理作为 targetClass 参数提供。因此，PointcutAdvisor 无法找到注释，因此不匹配。

为了完成，这是我的配置类:

@Configuration
@EnableTransactionManagement
public class MyConfiguration {

    @Bean
    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        return new DefaultAdvisorAutoProxyCreator();
    }

    @Bean
    public MyPointcutAdvisor myPointcutAdvisor() {
        return new MyPointcutAdvisor();
    } 
    ...
}

我的问题是:有没有办法将 @EnableTransactionManagement 与 StaticMethodMatcherPointcutAdvisor 结合使用？

解决方法:

• 将@CustomAnnotation放入服务接口(interface)中:我想要干净的接口(interface)。
• 将@Role(BeanDefinition.ROLE_INFRASTRUCTURE)添加到MyPointCutAdvisor bean配置中，这样，InfrastructureAdvisorAutoProxyCreator将创建代理。这似乎是错误的方式，因为这个 bean 不是基础设施

• 从ProxyTransactionManagementConfiguration复制bean，删除@EnableTransactionManagement并删除@Role(BeanDefinition.ROLE_INFRASTRUCTURE)，因此DefaultAdvisorAutoProxyCreator将创建代理，这是我当前的解决方法，并导致以下配置:

  @Configuration
  public class MyWorkaroundConfiguration {
      @Bean
      public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
          return new DefaultAdvisorAutoProxyCreator();
      }
  
      @Bean
      public MyPointcutAdvisor myPointcutAdvisor() {
          return new MyPointcutAdvisor();
      }
  
      @Bean
      public TransactionAttributeSource transactionAttributeSource() {
          return new AnnotationTransactionAttributeSource();
      }
  
      @Bean(name = TransactionManagementConfigUtils.TRANSACTION_ADVISOR_BEAN_NAME)
      public BeanFactoryTransactionAttributeSourceAdvisor transactionAdvisor(
              TransactionInterceptor transactionInterceptor) {
          BeanFactoryTransactionAttributeSourceAdvisor advisor =
              new BeanFactoryTransactionAttributeSourceAdvisor();
          advisor.setTransactionAttributeSource(transactionAttributeSource());
          advisor.setAdvice(transactionInterceptor);
          return advisor;
      }
  
      @Bean
      public TransactionInterceptor transactionInterceptor(
              PlatformTransactionManager transactionManager) {
          TransactionInterceptor interceptor = new TransactionInterceptor();
          interceptor.setTransactionAttributeSource(transactionAttributeSource());
          interceptor.setTransactionManager(transactionManager);
          return interceptor;
      } 
      ...
  }
  

Answer 1

使用 @EnableAspectJAutoProxy 而不是 DefaultAutoProxyCreator 对我有用。

@Configuration
@EnableAspectJAutoProxy
@EnableTransactionManagement
public class MyConfiguration {

}

这也允许像 M. Deinum 建议的那样使用 @Aspect。
