Which of the following is the correct way to use @Profile on a Spring bean class for the "dev" environment?

A@Profile("dev") public class DevService {}

B@Profile(dev) public class DevService {}

C@Profile({dev}) public class DevService {}

D@Profile(["dev"]) public class DevService {}

Step-by-Step Solution

Solution:

Step 1: Check correct syntax for @Profile
The @Profile annotation requires a string value in quotes, e.g., @Profile("dev").
Step 2: Analyze each option
@Profile(["dev"]) public class DevService {} uses square brackets, invalid Java annotation syntax. @Profile(dev) public class DevService {} misses quotes around "dev", syntax error. @Profile({dev}) public class DevService {} uses braces but misses quotes around "dev", syntax error. @Profile("dev") public class DevService {} uses correct quoted string syntax.
Final Answer:
@Profile("dev") public class DevService {} -> Option A
Quick Check:
@Profile needs quoted string [OK]

Quick Trick: Use quotes around profile names in @Profile [OK]
