medium📝 Debug Q6 of 15

Spring Boot - API Documentation

AThe OpenAPI bean method is private instead of public

BThe @Bean method is missing the @Configuration annotation on the class

CThe springdoc-openapi dependency version is too new

DThe application.properties file is missing

Step-by-Step Solution

Solution:

Step 1: Check bean registration requirements
For Spring to detect @Bean methods, the class must be annotated with @Configuration or be a Spring component.
Step 2: Understand impact of missing @Configuration
Without @Configuration, the bean method is ignored, so default OpenAPI info is used.
Final Answer:
The @Bean method is missing the @Configuration annotation on the class -> Option B
Quick Check:
Missing @Configuration = bean ignored [OK]

Quick Trick: Add @Configuration to register OpenAPI bean [OK]
