[Solved] What is wrong with this advice?@AfterReturning(pointcut = "execution(* service.*.getData(..))", returning = "result") public void advice(String data) { System.out.println(data); } | Spring Boot

Spring Boot - Aspect-Oriented Programming

What is wrong with this advice?

@AfterReturning(pointcut = "execution(* service.*.getData(..))", returning = "result")
public void advice(String data) {
    System.out.println(data);
}

AThe advice method should have no parameters.

BThe parameter name 'data' does not match the 'returning' attribute 'result'.

CThe pointcut expression is incorrect.

DThe advice method must return a value.

Step-by-Step Solution

Solution:

Step 1: Check parameter name vs returning attribute
The returning attribute is "result", so the advice method parameter must be named result.
Step 2: Identify mismatch
The method parameter is named "data", which does not match "result" causing a runtime error.
Final Answer:
The parameter name 'data' does not match the 'returning' attribute 'result'. -> Option B
Quick Check:
Parameter name must match returning attribute exactly [OK]

Quick Trick: Parameter name must match returning attribute [OK]

Common Mistakes:

Using different parameter name than returning attribute
Assuming parameter name can differ
Ignoring parameter name case sensitivity
