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.

Suggested 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.

I agree with D. It’s about integrating external properties effectively.

I feel like A is misleading. It’s not just about the location.

I think option D is the best choice. It adds properties to the Spring Environment.

D sounds interesting too, but I think A is the best answer here.

Wait, is it really just for the application.properties? Seems too limited.

I thought @PropertySource was mainly for designating file locations, but now I'm confused about whether that's A or C.

I feel like option D sounds right, but I can't recall if it specifically mentions external sources.

I remember practicing a question about Spring annotations, and I think @PropertySource is used to add properties to the Spring Environment.

Glory 4 months ago

I think @PropertySource is related to loading properties, but I'm not sure if it's specifically for application.properties or other files too.
