[apache/dubbo]注解加载服务配置，部分服务正常部分事务失效，Dubbo代理类跳过了Spring CGLib的代理

测试版本：(注：2.8.4的版本一样存在)

<dubbo.version>2.5.5</dubbo.version>
其他依赖版本：
<spring.version>4.3.10.RELEASE</spring.version>
<aspectj.version>1.7.4</aspectj.version>
<zookeeper.version>3.4.6</zookeeper.version>

问题简述： 同样写法下，用注解配置的服务，部分类会走SpringCGLib代理，而部分却跳过了代理，导致事务失效。 我认真比对了所有的写法，都一模一样，却出现了两种效果

备用解决方案： 出问题的类改用xml配置，一切正常，问题应该出在 Dubbo的注解扫描

项目说明： 使用了DBUtils，如下配置事务

     <\!--事务管理器配置-->
     <bean id="dataSourceProxy" class="org.springframework.jdbc.datasource.TransactionAwareDataSourceProxy">
         <constructor-arg name="targetDataSource" ref="ds"/>
     </bean>
     <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSourceProxy"/>
    <property name="nestedTransactionAllowed" value="true"/>
    </bean>
    <\!--Spring JDBC和DBUtils-->
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <constructor-arg name="dataSource" ref="dataSourceProxy"/>
    </bean>
    <bean id="queryRunner" class="org.apache.commons.dbutils.QueryRunner">
    <constructor-arg name="ds" ref="dataSourceProxy"/>
    </bean>
    <\!--事务注解支持-->
    <tx:annotation-driven transaction-manager="txManager"
                        proxy-target-class="true"/>

问题信息重现： 代码写法（简化中间内容）：

正常的如下：

public interface OrderCreateService {
    ...
}

@Service
@com.alibaba.dubbo.config.annotation.Service(version = "1.0.0", interfaceName = "com.temsoft.oms.order.service.OrderCreateService")
public class OrderCreateServiceImpl implements OrderCreateService {
    ...
}

同样写法，错误的如下：

public interface OrdersMngService {
    ...
}
@Service
@com.alibaba.dubbo.config.annotation.Service(version = "1.0.0", interfaceName = "com.temsoft.oms.order.service.OrdersMngService")
public class OrdersMngServiceImpl implements OrdersMngService {
    ...
}

Spring配置(spring 的扫描，我全部都用include-filter 和 use-default-filters="false"， 确定没有扫描两次)：

<!--注解方式加载-->
<dubbo:annotation />
<!-- 扫描注解Bean -->
<context:component-scan base-package="com.temsoft.oms" use-default-filters="false">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Service"/>
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Component"/>
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Repository"/>
</context:component-scan>

说明：在测试过程中发现，错误的类（OrdersMngService）在Jrebel重载时也会是重载的Spring CGLib代理的类，但是Dubbo调用的依旧跳过了该代理。

错误说明方式：服务端按简述方式编写，消费端直接调用，目标函数直接报异常，传出调用栈，栈信息如下：
