-----------------------------------------
Thanks for testing [~jmayer] - I've indeed reproduced the issue. I need to look
into this further, will get back to you in a bit.
> Actions with Spring's @Transactional and ModelDriven

> Key: WW-5534

> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors, Plugin - Spring

> Reporter: Johannes Mayer
> Priority: Minor
> Fix For: 7.1.0

> Hi,
> When using the ModelDriven interface, the getModel method has to be annotated
> with {_}@StrutsParameter{_}.
> When Spring decides to wrap an Action object with SpringCGLIB (e.g. when
> annotating a method with {_}@Transactional){_}, one has to add the Package to
> the allowList, so execute can be called. No harm done, just add this to the
> {_}struts.xml{_}:
> {code:java}
> <constant name="struts.allowlist.packageNames" value="your.action.package"/>
> {code}
> The now emerging problem is, that
> _org.apache.struts2.interceptor.parameter.ParametersInterceptor_ is not able
> to map the request parameter to the model, because it is not able to find a
> suitable _getModel_ method. The reason for this is, that the interceptor is
> trying to find the annotation on the SpringCGLIB class, which does not work.
> As a workaround, I can tell the ParameterInterceptor to not need a
> _@StrutsParameter_ annotation, but imo that defeats the purpose of this
> annotation. I am also warned not to make this configuration. I therefore
> assume that this scenario is not desirable.
> {code:java}
> <constant name="struts.parameters.requireAnnotations" value="false" /> {code}
> Spring's AopUtils gives the option the get to the real class:
> _AopUtils.getTargetClass(springCGLIBObject);_
> I created a project to showcase this:
> [https://github.com/sf-JMA/struts7-model-driven/|https://github.com/sf-JMA/struts7-model-driven/tree/main/src/main]
> I added a test
> [https://github.com/sf-JMA/struts7-model-driven/blob/main/src/test/java/com/steadforce/aek/struts7modeldriven/SpringAopVersusModelDrivenTest.java]
> to show the AopUtils method.
