Question 7

Which statement is true about the @PropertySource annotation? (Choose the best answer.)

AUsed to designate the location of the application.properties file in a Spring Boot application.

BUsed to easily look up and return a single property value from some external property file.

CUsed to designate the file directory of the application.properties file in a Spring Boot application.

DUsed to add a set of name/value pairs to the Spring Environment from an external source.

Answer : D

This is true because the @PropertySource annotation provides a convenient and declarative mechanism for adding a PropertySource to Spring's Environment. A PropertySource is an abstraction for a source of name/value pairs that can be used by the Environment to resolve properties. The @PropertySource annotation can be used to load properties from an external file, such as a .properties or .yml file, and make them available to the application context.
