Spring Boot - Actuator

Why does this custom actuator endpoint fail to expose data? @Component @Endpoint(id = "info") public class InfoEndpoint { public String details() { return "Details"; } } Accessing /actuator/info returns 404.

AThe method lacks @ReadOperation annotation to expose it

BThe class is missing @Endpoint annotation

CThe @Component annotation is misplaced

DThe endpoint id "info" conflicts with default endpoints

Step-by-Step Solution

Solution:

Step 1: Check method annotations
The method details() is not annotated with @ReadOperation, so it is not exposed.
Step 2: Confirm class annotations
The class has @Component and @Endpoint correctly.
Final Answer:
The method lacks @ReadOperation annotation to expose it -> Option A
Quick Check:
Methods need @ReadOperation to be exposed [OK]

Quick Trick: Annotate methods with @ReadOperation to expose them [OK]

Common Mistakes:

Assuming class annotations expose methods automatically
Thinking @Component alone exposes methods
Confusing endpoint id conflicts with method exposure
