TokenService is usually used with SSE.

@Import(OAuthConfig.class)
@Configuration
public class Config {
    ...
}

Autoimport the TokenService and call getAccessToken().
If the property fint.oauth.enabled is set to false the TokenService will be null.

@Autowired(required = false)
private TokenService tokenService;

public void myMethod() {
    if(tokenService != null) {
        String accessToken = tokenService.getAccessToken();
        ...
    }
}

OAuthRestTemplateFactory is used to create new instances of OAuth2RestTemplate.

Import the OAuthConfig class fro the @Configuration.

@Import(OAuthConfig.class)
@Configuration
public class Config {
    ...
}

Autoimport the OAuthRestTemplateFactory and call create(username, password, clientId, clientSecret).
If the property fint.oauth.enabled is set to false the OAuthRestTemplateFactory will be null.

@Autowired(required = false)
private OAuthRestTemplateFactory factory;

public void myMethod() {
    if(factory != null) {
        OAuth2RestTemplate restTemplate = factory.create(username, password, clientId, clientSecret);
        ...
    }
