我希望有人可以帮助我解决这个问题：

我想使用以下安全配置：

<security:global-method-security secured-annotations="enabled" proxy-target-class="true" />

使用 CGLib 作为代理而不是 JDK 动态代理的原因是因为使用了这样的扩展接口：

public abstract interface AbstractPromotionController {
    @RequestMapping(value = "edit", method = RequestMethod.GET)
    public void edit(final Model model, @RequestParam(value = "foo", required = false) final String foo, final HttpServletRequest request) throws IOException;
}

@RequestMapping("/foo/bar/blubb")
@Secured({ "ROLE_USER", "ROLE_ADMIN" })
public interface AmAktionController extends AbstractPromotionController {
}

不幸的是，这不起作用，因为如果使用继承，JDK 动态代理会丢失 RequestMapping 信息，不是吗？！

所以我尝试使用proxy-target-class="true" 上面的属性。但这似乎不能与 mybatis spring MapperFactoryBean 结合使用，我想用它来动态生成 DAO 实现：

<bean class="org.mybatis.spring.mapper.MapperFactoryBean">
   <property name="mapperInterface" 
       value="com.foo.bar.dao.api.admin.servicestatistic.StatisticLogDAO" />
   <property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>

这些配置会产生以下异常：

这个问题有什么解决办法吗？proxy-target-class="true"我可以更改 mybatis spring org.mybatis.spring.mapper.MapperFactoryBean 的行为吗？如何创建与spring 安全配置的属性结合使用的代理？

请帮我。我正在使用 spring 3.2.0、spring security 3.1.3 和 mybatis spring 1.1.1

谢谢， 奥利德

接口的注释不是从实现类继承的，因为不清楚如果两个具有相同注释和不同值的接口由同一个类实现会发生什么。如果手动生成动态代理，则必须将接口注解移动到代理类中。
