public class WSConfigClient {
    @Bean

    @ResponsePayload
    public UserClientResponse UserClientRequest(@RequestPayload UserClient request) throws Exception {

    try {

                UserClientConfig client = new UserClientConfig();

                response = client.getUserList(request);
                }catch(Exception e) {
                    e.printStackTrace();
