SPRING进行事务管理简单问题

我用SSH进行开发，使用SPRING代理STRUTS，我想进行HIBERNATE的事务管理，如果我显性进行事务管理，可以成功，但是在SPRING中配置事务就会出现异常，说无法创建bean。就是说我把事务管理的这段代码删除掉就异常了
我的SPRING配置如下

PROPAGATION_REQUIRED






myservice




interceptor2

异常如下：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name '/insert' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:
PropertyAccessException 1: org.springframework.beans.TypeMismatchException: Failed to convert property value of type [$Proxy3] to required type [dao.MyServiceImp] for property 'myservice'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [$Proxy3] to required type [dao.MyServiceImp] for property 'myservice': no matching editors or conversion strategy found
Caused by: org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessException details (1) are:
PropertyAccessException 1:
org.springframework.beans.TypeMismatchException: Failed to convert property value of type [$Proxy3] to required type [dao.MyServiceImp] for property 'myservice'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [$Proxy3] to required type [dao.MyServiceImp] for property 'myservice': no matching editors or conversion strategy found
Caused by: java.lang.IllegalArgumentException: Cannot convert value of type [$Proxy3] to required type [dao.MyServiceImp] for property 'myservice': no matching editors or conversion strategy found

我的理解是无法进行类型转化导致无法创建/insert找个bean,但是我没有进行类型转换啊，而且我不加事务处理的时候运行都很正常

从dao.MyServiceImp抽象一个接口dao.IMyService,
修改com.yourcompany.struts.action.InsertAction的下列方法：
[code="java"]
public void setMyservice(IMyService service){
//your code
}
[/code]
因为BeanNameAutoProxyCreator创建的是动态代理，必须在接口上创建。
