Spring Boot - Spring Annotations

A@Profile("dev & test")

B@Profile({"dev", "test"})

C@Profile("dev | test")

D@Profile("dev-test")

Step-by-Step Solution

Solution:

Step 1: Understand @Profile syntax
The @Profile annotation accepts an array of profile names, meaning the bean is active if any of the listed profiles is active.
Step 2: Analyze options
@Profile({"dev", "test"}) uses an array with "dev" and "test", which means the bean is active if either profile is active. @Profile("dev & test") uses an invalid syntax with '&' which means both profiles simultaneously, which is not supported. @Profile("dev | test") uses a string with '|', which is not valid syntax. @Profile("dev-test") uses a hyphen which is not a recognized operator.
Final Answer:
@Profile({"dev", "test"}) -> Option B
Quick Check:
Array syntax activates bean for any listed profile [OK]

Quick Trick: Use array syntax in @Profile for multiple profiles [OK]
