我有一个问题，Spring将代理注入到DAO对象中的服务中，但是这个服务被注入到控制器中，它是具体的类。这不允许我使用服务范围内的事务，并为每个DAO调用单独启动事务。这是我所期望的行为。
配置:
控制器是带有@Controller注释和构造函数DI的类。
服务:
@Component @Transactional public class UserServiceImpl implements UserService { ...}
DAO:
@Component @Transactional public class UserDaoImpl implements UserDao {
JPA配置:

<property name="jpaProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>

</property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
<tx:annotation-driven />
有人知道为什么会发生这种情况吗？
