Question

i am creating an aspect class with spring aspectj as follow

@Aspect
public class AspectDemo {
  @Pointcut("execution(* abc.execute(..))")
     public void executeMethods() { }

 @Around("executeMethods()")
    public Object profile(ProceedingJoinPoint pjp) throws Throwable {
            System.out.println("Going to call the method.");
            Object output = pjp.proceed();
            System.out.println("Method execution completed.");
            return output;
    }

} 

now i want to access the property name of class abc then how to acccess it in aspect class?
i want to display name property of abc class in profile method

my abc class is as follow

public class abc{
String name;

public void setName(String n){
name=n;
}
public String getName(){
 return name;
}

public void execute(){
System.out.println("i am executing");
}
}

How can i access the name in aspect class?

Answer 1

You need to get a reference to the target object and cast it to your class (after an instanceof check, perhaps):

Object target = pjp.getTarget();
if (target instanceof Abc) {
    String name = ((Abc) target).getName();
    // ...
}

The recommended approach (for performance and type safety) is to have the target mentioned in the pointcut:

@Around("executeMethods() && target(abc)")
public Object profile(ProceedingJoinPoint pjp, Abc abc) ....

But this will only match the executions on a target of type Abc.
