Answer 1

proxy controller with oauth2

@RequestMapping("v9")
@RestController
@EnableConfigurationProperties
public class ProxyRestController {
    Logger logger = LoggerFactory.getLogger(this.getClass());

    @Autowired
    OAuth2ProtectedResourceDetails oAuth2ProtectedResourceDetails;

    @Autowired
    private ClientCredentialsResourceDetails clientCredentialsResourceDetails;

    @Autowired
    OAuth2RestTemplate oAuth2RestTemplate;


    @Value("${gateway.url:http://gateway/}")
    String gatewayUrl;

    @RequestMapping(value = "/proxy/**")
    public String proxy(@RequestBody(required = false) String body, HttpMethod method, HttpServletRequest request, HttpServletResponse response,
                        @RequestHeader HttpHeaders headers) throws ServletException, IOException, URISyntaxException {

        body = body == null ? "" : body;
        String path = request.getRequestURI();
        String query = request.getQueryString();
        path = path.replaceAll(".*/v9/proxy", "");
        StringBuffer urlBuilder = new StringBuffer(gatewayUrl);
        if (path != null) {
            urlBuilder.append(path);
        }
        if (query != null) {
            urlBuilder.append('?');
            urlBuilder.append(query);
        }
        URI url = new URI(urlBuilder.toString());
        if (logger.isInfoEnabled()) {
            logger.info("url: {} ", url);
            logger.info("method: {} ", method);
            logger.info("body: {} ", body);
            logger.info("headers: {} ", headers);
        }
        ResponseEntity responseEntity
                = oAuth2RestTemplate.exchange(url, method, new HttpEntity(body, headers), String.class);
        return responseEntity.getBody();
    }


    @Bean
    @ConfigurationProperties("security.oauth2.client")
    @ConditionalOnMissingBean(ClientCredentialsResourceDetails.class)
    public ClientCredentialsResourceDetails clientCredentialsResourceDetails() {
        return new ClientCredentialsResourceDetails();
    }

    @Bean
    @ConditionalOnMissingBean
    public OAuth2RestTemplate oAuth2RestTemplate() {
        return new OAuth2RestTemplate(clientCredentialsResourceDetails);
    }
