How to call an application.yaml parameter in the method signature? Java

I have a method whose signature is a String that is placed explicitly, but I would like to add this String message in the application.yaml and call it in the method, as shown below:

publishesPublic.replyRefusal(map, "500", "AC0001", "The request could not be processed at this time. Try again later.");

How do I leave the message in the application.yaml and call it in the method?

Thanks in advance!

Application yaml file will have the following entry.

tryAgainMessage: Try again later

Get it injected in java code as follows

@Value("${tryAgainMessage}")
private String tryAgainMessage;

Use it

publishesPublic.replyRefusal(map, "500", "AC0001", tryAgainMessage);

You can add it to application.yml with a key :

error:
   message: The request could not be processed at this time. Try again later.

And in you bean, you can inject the value like this :

private String errorMessage;

public YourBean(@Value("${error.message}") String errorMessage) {
    this.errorMessage = errorMessage;
}

You can inject it using field injection too, but using constructor is a better practice.

And then :

publishesPublic.replyRefusal(map, "500", "AC0001", errorMessage);
