[Solved] You have two beans annotated with @Profile("test") and @Profile("prod") respectively.... What is the most likely cause? | Spring Boot

Spring Boot - Spring Annotations

You have two beans annotated with @Profile("test") and @Profile("prod") respectively. When running the app with no active profile set, you get a NoSuchBeanDefinitionException. What is the most likely cause?

AThe beans are not annotated with @Component

BThe beans have syntax errors in @Profile annotation

CSpring Boot does not support @Profile annotation

DNo profile is active, so no beans with @Profile are created

Step-by-Step Solution

Solution:

Step 1: Understand @Profile behavior with no active profile
If no profile is active, Spring does not create beans annotated with any specific profile.
Step 2: Analyze exception cause
NoSuchBeanDefinitionException means Spring could not find a bean to inject because none were created due to missing active profile.
Final Answer:
No profile is active, so no beans with @Profile are created -> Option D
Quick Check:
No active profile means no profile-specific beans [OK]

Quick Trick: Beans with @Profile need active profile to load [OK]

Common Mistakes:

Assuming beans load without active profile
Blaming syntax errors without checking profiles
Ignoring need for @Component on beans
