Hi Conrad, You are right, this is a good use for the
cflow pointcut designator. E.g., …
public pointcut actionMethodExec(HttpServletRequest request) : pointcut
businessOperation(request) : cflow(strutsAction(request))
&& businessMethod(); // businessMethod() is your existing pointcut
before(HttpServletRequest request) : businessOperation(request) { See for
example http://www.eclipse.org/aspectj/doc/released/progguide/language-joinPoints.html
for more about cflow This is related to the wormhole pattern which is
described in AspectJ in Action… Ron From:
[EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Conrad CRAMPTON PSE 52704 Hi, I want to provide
an aspect that audits certain method calls in a struts based application. Can
anyone give me some good practice on how to do this? Currently I have
an aspect which I have successfully set up to pick out my business methods that
I am concerned with but at the business layer, there is no visibility of the
httpsession variables that hold my user details. I want to use these user
details to add to the auditing messages but don't know how to 'pass' them into
the business method. Do I just make
the struts action that calls the business method in question the pointcut
instead of the business method itself and therefore get a handle on the
HttpServletRequest (and therefore the session and its attributes) or should I
have some sort of cflow pointcut of my action and business method. I don't
really 'get' cflow pointcuts just yet but sort of feel that this is an option. Any suggestions
would be most welcome here for someone very new to AOP - even though what I
have done so far leads me to believe I will be using aspects much more in the
future. TIA Conrad |
