Use a REST web service with OAuth protection using Spring oauth2

Question

I want to use a REST web service from a server that protects its resources using oauth2.

I am using Spring boot (JHipster).

For this, in my class, SecurityConfigurationthis is:

@Value("${oauth.resource:http://sercverUsingOAuth2}")
private String baseUrl;

@Value("${oauth.authorize:http://sercverUsingOAuth2/rest/oauth/token}")
private String authorizeUrl;

@Value("${oauth.token:http://sercverUsingOAuth2/rest/oauth/token}")
private String tokenUrl;

@Bean
public OAuth2RestOperations oauth2RestTemplate() {
    AccessTokenRequest atr = new DefaultAccessTokenRequest();
    return new OAuth2RestTemplate(resource(),
            new DefaultOAuth2ClientContext(atr));
}

@Bean
protected OAuth2ProtectedResourceDetails resource() {
    AuthorizationCodeResourceDetails resource = new AuthorizationCodeResourceDetails();
    resource.setAccessTokenUri(tokenUrl);
    resource.setUserAuthorizationUri(authorizeUrl);
    resource.setClientId("client_id");
    resource.setClientSecret("client_secret");
    resource.setGrantType("grant_type");
    return resource;
}

This class ( SecurityConfiguration) is written with:

@Configuration
@EnableWebSecurity
@EnableOAuth2Client

And this is mine controller(Spring MVC):

@RestController
@RequestMapping("/consume")
public class MyContrtoller {

@Inject
private OAuth2RestOperations oauth2RestTemplate;

@RequestMapping(value = "/oauth2", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
public List<DataModel> getProducts() {

    ResponseEntity<MyModel> forEntity = oauth2RestTemplate
            .getForEntity("http://sercverUsingOAuth2/rest/resourceToConsume",
                    MyModel.class);
    return forEntity.getBody().getData();
}

}

However, when I want to use my web service ( http: // myHost / consume / oauth2 ), I get this exception:

    org.springframework.security.oauth2.client.resource.OAuth2AccessDeniedException:
 Unable to obtain a new access token for resource 'null'. The provider manager
 is not configured to support it.

I have googled and I found this:

• github
• stack overflow

But it doesn’t help me.

Thank.

URL- URL- -. , .

, , "AuthorizationCodeResourceDetails", "ClientCredentialsResourceDetails". ResourceDetails , .

ClientCredentialsResourceDetails resource = new ClientCredentialsResourceDetails();
resource.setAccessTokenUri(TOKEN_URL);
resource.setClientId(CLIENT_ID);
resource.setClientSecret(CLIENT_SECRET);
resource.setClientAuthenticationScheme(AuthenticationScheme.form); //This line isn't always needed
return resource;
