Class access variable in class aspect

Question

I am creating an aspect class with spring aspectj as follows

@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 the abc class, and then how to get it in the aspect class? I want to show the abc class name property in the profile method

my abc class is as follows

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 the class aspect?

Answer 1

You need to get a link to the target object and apply it to your class (perhaps after checking instanceof):

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

The recommended approach (to ensure type safety and type safety) is to indicate the purpose specified in the pointcut:

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

Abc.

ProceedingJointPoint :

@Around("executeMethods()")
public Object profile(ProceedingJoinPoint pjp) throws Throwable {

    Class myClass = jp.getStaticPart().getSignature().getDeclaringType();
    for (Field field : myClass.getDeclaredFields())
    {
        System.out.println(" field : "+field.getName()+" of type "+field.getType());
    }

    for(Method method : myClass.getDeclaredMethods())
    {
        System.out.println(" method : "+method.toString());
    }
    ...
}

java.lang.reflect

Spring, AOPUtils

 public Object invoke(MethodInvocation invocation) throws Throwable
 {
      Class<?> targetClass = AopUtils.getTargetClass(invocation.getThis())
 }
