I need help with the error when trying to access the oAuth2 token using OAuth2RestTemplate

My java code is provided below.

I am using Spring version 4.3.4 and Spring Security oAuth version 2.3.4

Thank you!

ClientCredentialsResourceDetails returnValue = new   ClientCredentialsResourceDetails();
returnValue.setAccessTokenUri(xxx);
returnValue.setClientId(yyy);
returnValue.setGrantType("client_credentials");
returnValue.setClientSecret(zzz);

AccessTokenRequest atr = new DefaultAccessTokenRequest();
OAuth2RestTemplate restTemplate = new OAuth2RestTemplate(returnValue , new DefaultOAuth2ClientContext(atr));
restTemplate.setRequestFactory(getClientHttpRequestFactory());

logger.debug(restTemplate.getAccessToken());

When I create a JUnit test class and run this, I get the following error trace. The oAuth2 REST API works using SOAP UI.

    error="access_denied", error_description="Error requesting access token."

Did you remember to add the content type? (Of course, for your mock response side)

.withHeader(header("Content-Type", "application/json;charset=UTF-8"))
