Question 73

Which two statements are correct regarding the differences between @ConfigurationProperties and @Value? (Choose two.)

@Value must be used for environment variables, as @ConfigurationProperties cannot access the environment.

@Value supports relaxed binding of properties, but not property binding through SpEL.

@ConfigurationProperties is preferable over @Value when type-safety during property binding is a concern.

@ConfigurationProperties only bind properties from .properties files, not from .yml files.

@ConfigurationProperties supports relaxed binding of properties, but not property binding through SpEL.

Correct Answer: C, E

ConfigurationProperties is preferable over @Value when type-safety during property binding is a concern. Additionally, @ConfigurationProperties supports relaxed binding of properties, but not property binding through SpEL. This makes @ConfigurationProperties suitable for binding externalized configuration properties to strongly-typed beans, ensuring that the loaded values conform to specific types or structures.
