Using Java and Spring Boot and my @Value annotation for my application-dev.properties is not being resolved?

This is my very first question so I apologize if it is not specific enough (please be gentle haha) and I have already gone through documentation, but I am new to the field and none of it helped.

I am making a simple project that uses Java 18 and Spring Boot to make a call to an external API call and I want to hide my API key that I use for obvious reasons.

As of right now, I have an application-dev.properties file in my resources directory with the following (I am making up the actual key for security) and I have application-dev.properties in my .gitignore file so it doesn't get committed:

api-key=someText

And I am trying to use that value in my controller like so:

@RestController
public class ImageController {

    @Value("${api-key}")
    private String API_KEY;

    @RequestMapping(value = "/image")
    public List<String> getImages(@RequestParam(defaultValue = "4") String request) {

        String url = "https://api.nasa.gov/planetary/apod?" + API_KEY + request;
        RestTemplate restTemplate = new RestTemplate();

The error I am receiving is this:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'imageController': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'api-key' in value "${api-key}"

Thanks in advance!

As mentioned in the other answer, the name of the application-dev.properties file requires that you activate the "dev" profile or Spring Boot will never read it and the values therein will not be available to your @Value annotation.

Here is a link to a Baeldung article that discusses Spring Boot profiles: Spring Boot Profiles at Baeldung (I am not associated with Baeldung, I just like much of their stuff).

If you are not planning to use profiles in your application, change the name of the properties file to "application.properties".

As you mentioned you are using application-dev.properties therefore you have to do profiling correctly. In your application.properties add spring.profiles.active=dev to activate dev profile.
