[FIXED] How to read from application.yml file in Java

Issue

I wrote an e mail program. But I had to change the some configs, so in my project I need to know how to read from yaml for my loginUrl

my code below;

userNotificationEmail.setIsActive("F");
                                userNotificationEmailRepository.save(userNotificationEmail);
                                activationResultType.setResultCode(ActivationResultCode.SUCCESSFUL);
                                activationResultType.setUser(userMapper.fromUser(userEntity));
                                activationResultType.setLoginUrl(loginUrl); 
                                return activationResultType;

Solution

If your key is loginUrl (inside your yaml file), you can inject its value with the @Value annotation, inside a Spring component.

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

If it's a second level property, the path is @Value("${yourFirstKey.loginUrl}").
