Spring AOP方面不起作用

Question

我正在为我的应用程序使用Spring + Hibernate + GWT，它运行正常。我现在想用AOP捕获异常，因为我使用事务并且一个简单的try / catch块无法完成这项工作。这是我在x.y.z.server.dao包中的代码：

public abstract class AbstractHibernateJpaDAO<K, E> {
protected Class<E> entityClass;

@SuppressWarnings("unchecked")
public AbstractHibernateJpaDAO() {
    ParameterizedType genericSuperclass = (ParameterizedType) getClass()
            .getGenericSuperclass();
    entityClass = (Class<E>) genericSuperclass.getActualTypeArguments()[1];
}

public void persist(E entity) {
    getEntityManager().persist(entity);

}
...   
private abstract EntityManager getEntityManager();
}

我的DAO继承了这个类：

@Repository("billOfLadingDAO")
public class BillOfLadingDAO extends
    AbstractHibernateJpaDAO<String, BillOfLading> {

@PersistenceContext(unitName = "MyPUnit")
EntityManager entityManager;

@Override
public EntityManager getEntityManager() {
    return entityManager;
}

我的服务在包x.y.z.server.dao.daoserviceimpl中实现如下

@Service("billOfLadingService")
public class BillOfLadingServiceImpl extends RemoteServiceServlet implements
    BillOfLadingService {

private static final long serialVersionUID = -1282872068303829279L;

private static final Log LOG = LogFactory
        .getLog(BillOfLadingServiceImpl.class);

@Autowired
private BillOfLadingDAO billOfLadingDAO;

@Override
@Transactional(propagation = Propagation.REQUIRED, rollbackFor =      MesExceptions.class)
public void save(BillOfLadingDTO billDTO) throws MesExceptions,Exception {

    try {
        if(billDTO.getUpdate()){
        billOfLadingDAO.merge(bill);
        }else {
        billOfLadingDAO.persist(bill);
        }

    } catch (DataAccessException e) {
        LOG.error(e);
         throw new MesExceptions();
    }catch(Exception eb){
         throw new MesExceptions();
}

的applicationContext.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<tx:annotation-driven />

<context:annotation-config />

<context:component-scan base-package="x.y.z" />
 <aop:aspectj-autoproxy />

<bean
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
    id="entityManagerFactory">
    <property name="persistenceUnitName" value="MyPUnit" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
    </property>
</bean>

<bean class="org.springframework.orm.jpa.JpaTransactionManager"
    id="transactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

<bean id="persistenceExceptionTranslationPostProcessor"
    class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostPro     cessor" />

</beans>

我写了这样的建议，以便捕获dataaccessexception

@Component
@Aspect
public class AfterThrowingIntercept {

@AfterThrowing(pointcut = "within(x.y.z.server.dao..*)", throwing = "ex")
public void errorInterceptor(DataAccessException ex) throws Throwable {
    throw new MesExceptions();
}   
}

我像这样调用save methode billOfLadingService

billOfLadingService.save(bill, new AsyncCallback() {
...
});

以下是完整的堆栈跟踪：

但是当我像重复项目一样抛出异常时，我的建议不起作用。谁能帮我？

注意：我想抛出自己的异常，因为spring异常不可序列化并且无法通过gwt rpc调用传输。
