Dịch vụ ủy quyền của tôi trả về http 204 thành công và http 401 thất bại nhưng không có responseBody. Tôi không thể tiêu thụ điều này với máy khách RestTemplate. Nó không cố gắng serialize phản ứng. Các lỗi từ Jackson đề nghị mà tôi bật FAIL_ON_EMPTY_BEANS trong serializer, nhưng làm thế nào để thiết lập này trong restTemplateCách xử lý phản hồi trống trong Spring RestTemplate
Các khách hàng tiêu thụ các api còn lại

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
RestTemplate restTemplate = new RestTemplate();
System.out.println("\n\n\n\n ============API REQUEST INTERCEPTOR=============== \n\n\n\n\n");
if(StringUtils.isBlank(request.getHeader(AuthenticationKeys.AUTHENTICATIONTOKEN.name().toLowerCase()))){
//TODO AUTHORIZE TOKEN
ResponseEntity<AuthenticationResponse> authenticateResponse = restTemplate.getForEntity(authenticateUrl, AuthenticationResponse.class);

//TODO SET THE TOKEN IN THE CONTEXT
