Hi,
I am new to AspectJ. I am working on a legacy web project which has hundreds of file. I have written an aspect to capture the query call. So, I require to weave only DAO class. Is there any way I can instruct the aspectj compiler to only weave the required files.
For example, i want have the dao weave under different dao pakes as below:
com.xyx.p1.dao
com.xyz.p2.dao
com.zzz.p3.dao

So is there any way that i can write the expression so that asjpectj compiler would weave only the files within the package ending with *.dao

You should use the within pointcut for this:

pointcut targetPackages() : within(com.xyx.p1.dao..*.*) || 
        within(com.xyx.p2.dao..*.*) || <etc...>;

And then use this pointcut with your other advice to ensure that the compiler scopes the target of other advice properly. Kind of like this:

before() : targetPackages() && <someotherpointcuts> {
  // do sumpin
}

Thanks Andrew for the reply. But I want to do something as below:
Match the package Starting with say "com.xyz" and followed by anything and then ending with "dao". Can I write expression for such case in the pointcut.

True, the pointcut could be simplified like this

ointcut targetPackages() : within(com..*.dao..*.*);

Hi,
I tried with that and it works. But even with this AspectJ compiler tries to weave all the classes present in the src directory. Is there any way I can specify compiler to weave only the required packages and skip trying to weave others.

What is the problem with trying to weave all classes? If aspects don't apply to them, they will not be changed. Is it taking too long?
