How to get the environment variable from local using @Value in spring?

I set a key inside my environment (in bash_profile file) called 'FLAG'(the value is 'true'). I'm trying to get his value by using annotation Value. so far i tried to do this:

@Value("\${FLAG}")
 private lateinit var process_flag: String

but no success, I'm getting an error:

java.lang.IllegalArgumentException: Could not resolve placeholder 'FLAG' in string value "${FLAG}"

*should I add any import\annotation to the class?

Solution: maybe it will sound funny but the solution for me was to turn off and on the intellij, of course after declare the environment variable.

For the custom source locations try to add this annotation into your config: 

@PropertySource("classpath:{whatever_you_want_path}")

Spring cannot see what is inside bash_profile file it rather gives access to Jvm system properties. Try below:

java .... -DFLAG=${FLAG}

"DFLAG" is jvm system property and "flag" is the value in bash_profile file.

Try providing a default value in case the variable is not defined:

@Value("${some_property:default_value}")
private String key;

Otherwise you'll get an exception whenever some_property is not defined.

If that doesn't work you can also try:

@Component
public class SomeClass {

    @Value("#{environment.SOME_KEY_PROPERTY}")
    private String key;

    ....
}
