SSH框架配置事物，Action出错，费时费力不明白，求指导！！

求大家帮忙，小弟初学者！
我在UserAction中的内容是
private IUserService userservice;
//依赖注入业务逻辑组件
public void setUserservice(IUserService userservice) {
this.userservice = userservice;
}
配置文件如下

  1.   

    其实就是只句话：org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'UserAction' defined in class path resource [applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type '$Proxy4 implementing app.service.IUsersService,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised' to required type 'com.portal.user.service.IUserService' for property 'userservice'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [$Proxy4 implementing app.service.IUsersService,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised] to required type [com.portal.user.service.IUserService] for property 'userservice': no matching editors or conversion strategy found
      

  2.   

    UserDAO UserService确定定义的是接口？
      

  3.   

    他们是实现类，接口是IUserDAO,IUserService
      

  4.   

    UsersService   你action注入的时候  应该是UserService
      

  5.   

    我怎么感觉 <aop:config>
             <aop:pointcut id="allServiceMethod" expression="execution(* app.service.*.*(..))" />
             <aop:advisor pointcut-ref="allServiceMethod" advice-ref="txAdvice" />
        </aop:config>    这里不对

    嗯嗯 发现了，谢谢我还发现了一个错误，expression="execution(* app.service.*.*(..)"我上网查的配置，就照搬过来了，，应该还要该成expression="execution(* com.portal.*.service.*.*(..) （有点不确定，我改了，没发现有错的，嘿嘿），才符合我的项目哎，初学就是只会照搬，我得加油了
