Spring Boot - Aspect-Oriented Programming

Given this aspect code snippet:

@Aspect
@Component
public class LogAspect {
  @Before("execution(* com.example.service.*.*(..))")
  public void logBefore() {
    System.out.println("Before method call");
  }
}

What will be printed when someService.someMethod() is called?

AException thrown

BAfter method call

CNo output

DBefore method call

Step-by-Step Solution

Solution:

Step 1: Identify advice type
The @Before advice runs before the matched method executes.
Step 2: Match pointcut expression
The pointcut matches all methods in com.example.service package, so someMethod() matches.
Final Answer:
Before method call -> Option D
Quick Check:
@Before advice prints before method [OK]

Quick Trick: @Before advice prints before method execution [OK]

Common Mistakes:

Expecting output after method
Ignoring pointcut matching
Assuming exception thrown
