        @Value("${ForgotPassword}")

    }

Answer 1

Spring does not support @Value injection on static fields.

Are you sure that you definitely require a "static class for AppSettings"? I suspect that might represent a misunderstanding of how Spring singletons work.

If, however, you have a genuine need for a "static class for AppSettings" then you can achieve this as follows:

@Value("${CryptoKey}")
public void setCryptoKey(String cryptoKey) {
    AppSettings.CryptoKey = CryptoKey;
}

@Value() gets called on the initialization of the bean , the bean gets initialized on need not on the startup so you will not have the value unless the bean is initialized
