Spring Boot - Aspect-Oriented Programming

How can you exclude logging advice from applying to methods annotated with @NoLogging in com.example package?

A@Before("execution(* com.example..*(..)) && !@annotation(com.example.NoLogging)") public void log() { ... }

B@Before("execution(* com.example..*(..)) || @annotation(com.example.NoLogging)") public void log() { ... }

C@Before("execution(* com.example..*(..))") @Exclude("@annotation(com.example.NoLogging)") public void log() { ... }

D@Before("execution(* com.example..*(..))") public void log(@NoLogging Object obj) { ... }

Step-by-Step Solution

Solution:

Step 1: Use pointcut expression to exclude annotation
The expression uses !@annotation(...) to exclude methods with @NoLogging.
Step 2: Check other options
@Before("execution(* com.example..*(..)) || @annotation(com.example.NoLogging)") public void log() { ... } includes methods with the annotation, @Before("execution(* com.example..*(..))") @Exclude("@annotation(com.example.NoLogging)") public void log() { ... } uses invalid @Exclude, and @Before("execution(* com.example..*(..))") public void log(@NoLogging Object obj) { ... } incorrectly tries to inject annotation as parameter.
Final Answer:
Option A with negation of annotation in pointcut -> Option A
Quick Check:
Exclude with !@annotation in pointcut [OK]

Quick Trick: Use !@annotation to exclude methods with specific annotation [OK]
