#3 MethodInterception AOP does not work

[Anonymous]

Hello. I have problem with using spring AOP with beans which extend GWTSpringController. Here is my config:

<bean id="urlMapping"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop <prop key="/admin/UserService.gwt">userService</prop>
</props>
</property>
</bean>

<bean id="userService"
class="some.client.rpc.UserServiceImpl">
</bean>

UserServiceImpl extends GWTSpringController. The code works fine and there is not problem with execution. The problem starts when i want to use AOP advices. I need this for security (acegi supports URL security and methodInvocation security). I want to use method security.

<bean id="securityAspect"
class="some.aop.SecurityAspect">

</bean>
<aop:config>

<aop:aspect ref="securityAspect">

<aop:pointcut id="theExecutionOfSomeFooServiceMethod"
expression="execution(* some.client.rpc.UserService.*(..))"/>

<aop:around pointcut-ref="theExecutionOfSomeFooServiceMethod"
method="profile"/>

</aop:aspect>
</aop:config>

it does not work. When i use the same aspect in another pointcut ex. execution(* some.client.rpc.AdminService.*(..)) it executes well. My implementation of UserServiceImpl invokes AdminService.

So basically i cannot use aop with beans which extend GWTSpringController. I suspect Reflection is causing problems. Probably AOP does not work with reflection.

I also tried to use org.acegisecurity.intercept.method.aopalliance.MethodSecurityInterceptor which again works for AdminService and not for UserService.

Is it possible to run such thing using GWT-SL ??

Please check this thread which may be useful http://forum.springframework.org/showthread.php?t=46537

Is it possible to check for AccessDeniedException to automatically return 403 Forbiddenin response ??

Are you planning to add some Acegi integration features ??

Ok it seems somehow it finally worked. Now exception is catched correctly by acegi.
Probablly my config was wrong but i don;t know exactly what it was.

Keep on good work...

Please consider using GWTHandler or even better GWTRPCServiceExporter

Since in the SL we do only standard stuff like providing controllers and request handler, it should not be a problem to integrate it with Acegi without any changes to the SL.

Hello Artur

The nice thing with Acegi, and for this part with Spring/AOP in general is that as a library designer one rarely has to add any features in regard to integration with other libraries - you just wire that functionality via IoC together. If you find any particular problem where the SL inhibits cooperation with Acegi, please tell us so that we can fix it!
