Subject [jira] Resolved: (BEANUTILS-298) MethodUtils.getAccessibleMethod(Method method) could not find right public method
Date Thu, 03 Apr 2008 03:10:24 GMT


Niall Pemberton resolved BEANUTILS-298.

    Resolution: Fixed
      Assignee: Niall Pemberton

Thanks for reporting this. Unfortunately in this scenario there is no fix for MethodUtils.getAccessibleMethod(Method)
- since it can only check superclasses/interfaces of the class returned by Method.getDeclaringClass().
In your scenario the declaring class is BaseX and therefore the interface IX is not available.
So I have added a new MethodUtils.getAccessibleMethod(Class, Method) method which can be used
instead. I have changed PropertyUtils to use this new method so that now your PropertyUtils.getProperty(beanOfTypeBaseX,
"name")  works:

Closing this as fixed.

>          Components: Bean / Property Utils
>    Affects Versions: 1.7.0, 1.8.0-BETA
>         Environment: Java 1.5, Windows XP

>            Priority: Minor
>             Fix For: 1.8.0
> Let assume follows:
> public interface IX {
>   getName();
> }
> class BaseX {
>   public getName();
> }
> class ImplX  extends BaseX implements IX {
> }
> For some reason I do not want that BaseX implements IX, but if we have a bean of type
ImplX we can call getName().
> PropertyUtils.getProperty(beanOfTypeBaseX, "name") could not get the value, because the
method MethodUtils.getAccessibleMethod(Method method)  looks up only throunght supercalsses
and interfaces of implementing class but not the subclasses and interfaces that they implement!
> So PropertyUtils.getProperty(beanOfTypeBaseX, "name") throws an Exception that the method
is not accessible, but at the same time I can call beanOfTypeBaseX.getName()
