[Solved] Identify the error in this advice method for logging exceptions:@AfterThrowing(pointcut = "execution(* com.example.*.*(..))", throwing = "ex") public void logException(Exception e) { System.out.... | Spring Boot

Spring Boot - Aspect-Oriented Programming

Identify the error in this advice method for logging exceptions:

@AfterThrowing(pointcut = "execution(* com.example.*.*(..))", throwing = "ex")
public void logException(Exception e) {
    System.out.println("Exception: " + e.getMessage());
}

AMissing @Before annotation

BPointcut expression is invalid

CAdvice method must return a value

DParameter name mismatch between 'ex' and 'e'

Step-by-Step Solution

Solution:

Step 1: Check parameter name binding
The throwing attribute is set to "ex" but the method parameter is named e. They must match.
Step 2: Confirm other parts are correct
The pointcut is valid, advice methods do not return values, and @Before is unrelated here.
Final Answer:
Parameter name mismatch between 'ex' and 'e' -> Option D
Quick Check:
throwing attribute name = method parameter name [OK]

Quick Trick: Match throwing attribute and parameter names exactly [OK]

Common Mistakes:

Using different names for throwing and parameter
Thinking advice must return a value
Confusing pointcut syntax errors
