Using Spring Security with Spring Starter Web and WebClient

iUser wants to draw more attention to this question.
I'm using Spring Boot 3 and configured spring-boot-starter-web and spring-boot-starter-webflux. I added Webflux to use the WebClient with HttpExchange. I have also created another spring boot project with some rest endpoints to use the WebClient. Second service creates entry in DB.
I have also configured Spring Security in first service and doing JWT based authentication and also configured #RestControllerAdvice for error responses.
Below is my WebSecurity Configuration class
#Configuration
#EnableWebSecurity
#EnableMethodSecurity
public class WebSecurityConfig {
#Bean
AuthTokenFilter authenticationJwtTokenFilter() {
return new AuthTokenFilter();
}
#Bean
AuthenticationProvider authenticationProvider(UserDetailsServiceImpl userDetailsService) {
DaoAuthenticationProvider authProvider = new DaoAuthenticationProvider();
authProvider.setUserDetailsService(userDetailsService);
authProvider.setPasswordEncoder(passwordEncoder());
return authProvider;
}
#Bean
AuthenticationManager authenticationManager(AuthenticationConfiguration authConfig) throws Exception {
return authConfig.getAuthenticationManager();
}
#Bean
PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
#Bean
SecurityFilterChain filterChain(HttpSecurity http, AuthEntryPoint unauthorizedHandler,
AppAccessDeniedHandler accessDeniedHandler, UserDetailsServiceImpl userDetailsService) throws Exception {
http.cors().and().csrf().disable().exceptionHandling().accessDeniedHandler(accessDeniedHandler)
.authenticationEntryPoint(unauthorizedHandler).and().sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS).and().authorizeHttpRequests()
.requestMatchers("/auth/**").permitAll().requestMatchers("/test/**").permitAll()
.requestMatchers("/v3/api-docs", "/api-docs/**", "/configuration/ui", "/swagger-resources",
"/configuration/security", "/swagger-ui.html", "/swagger-ui/**", "/webjars/**",
"/swagger-resources/configuration/ui", "/swagger-ui.html", "/actuator/**")
.permitAll().requestMatchers("/user/{id}/**").access(new AppAuthorizationManager()).anyRequest()
.authenticated();
http.authenticationProvider(authenticationProvider(userDetailsService));
http.addFilterBefore(authenticationJwtTokenFilter(), UsernamePasswordAuthenticationFilter.class);
return http.build();
}
}
AuthenticationEntryPoint
#Component
#Slf4j
public class AuthEntryPoint implements AuthenticationEntryPoint {
#Autowired
private ObjectMapper objectMapper;
#Override
public void commence(HttpServletRequest request, HttpServletResponse response,
AuthenticationException authException) throws IOException, ServletException {
log.error("Authentication error: {}", authException);
HttpStatus httpStatus = HttpStatus.UNAUTHORIZED;
response.setContentType(MediaType.APPLICATION_JSON_VALUE);
response.setStatus(httpStatus.value());
var body = AccessResponseUtls.getResponseBody(request, httpStatus);
objectMapper.writeValue(response.getOutputStream(), body);
}
}
AccessDeniedHandler
#Component
#Slf4j
public class AppAccessDeniedHandler implements AccessDeniedHandler {
#Autowired
private ObjectMapper objectMapper;
#Override
public void handle(HttpServletRequest request, HttpServletResponse response,
AccessDeniedException accessDeniedException) throws IOException, ServletException
{
log.error("Forbidden error: {}", accessDeniedException);
HttpStatus httpStatus = HttpStatus.FORBIDDEN;
response.setContentType(MediaType.APPLICATION_JSON_VALUE);
response.setStatus(httpStatus.value());
var body = AccessResponseUtls.getResponseBody(request, httpStatus);
objectMapper.writeValue(response.getOutputStream(), body);
}
}
I have configured Client via [#HttpExchange][1] and using WebClient.
WebClient webClient(String url) {
return WebClient.builder()
// .filter(errorHandler())
.baseUrl(url)
.build();
}
public static ExchangeFilterFunction errorHandler() {
return ExchangeFilterFunction.ofResponseProcessor(clientResponse -> {
log.info("Client Response => {}", clientResponse.bodyToMono(Customer.class));
log.info("Status Code = {}", clientResponse.statusCode());
if (clientResponse.statusCode().is5xxServerError()) {
log.error("Got 5xx Error");
return clientResponse.bodyToMono(String.class)
.flatMap(errorBody -> Mono.error(new RuntimeException(errorBody)));
} else if (clientResponse.statusCode().is4xxClientError()) {
log.error("Got 4xx Error");
return clientResponse.bodyToMono(String.class)
.flatMap(errorBody -> Mono.error(new InvalidParametersException(errorBody)));
} else {
return Mono.just(clientResponse);
}
});
}
#Bean
CustomerClient customerClient() {
HttpServiceProxyFactory httpServiceProxyFactory = HttpServiceProxyFactory
.builder(WebClientAdapter.forClient(webClient("http://localhost:8081/api/v1/"))).build();
return httpServiceProxyFactory.createClient(CustomerClient.class);
}
Authentication is done in first service properly. And when I try to access the second service through postman, it works fine, creating an entry in DB and responds with 201 as expected. But from the First Service, it always responds with Unauthorized.
AuthenticationEntryPoint is getting executed. I tried to enable error handler in WebClient (Commented code - filter(errorHandler())). Status code is 201 as expected. But still AuthEntryPoint is getting invoked which causes 401 response.
How to get the proper response and send back? And if error response is coming from second service, how to handle it in #RestControllerAdvice? or do we need to handle through WebClient filter only? If so how?
Log from Error handler
Client Response => checkpoint("Body from POST http://localhost:8081/api/v1/course [DefaultClientResponse]")
Status Code = 201 CREATED

Update 1
CustomerClient - Client Interface
#HttpExchange("/customer")
public interface CustomerClient {
#PostExchange
Mono<ResponseEntity<Customer>> create(#RequestBody CustomerDTO customerDTO);
}
Controller Class
#CrossOrigin(origins = "*", maxAge = 3600)
#RestController
#RequestMapping("/Customer")
#Slf4j
public class CustomerController {
#Autowired
private CustomerClient customerClient;
#PostMapping
public Mono<ResponseEntity<Customer>> create(#RequestBody #Valid CustomerDTO customerDTO) {
log.info("Creating....");
return customerClient.create(customerDTO);
}
}

I was facing a similar issue. I was using WebFlux for using WebClient only and not the complete reactive feature.
I did not add the WebClient filter method. Error responses were handled by #RestControllerAdvice.
Change your controller to return the body instead of Mono/Flux
#PostMapping
public ResponseEntity<Customer> create(#RequestBody #Valid CustomerDTO customerDTO) {
log.info("Creating....");
return customerClient.create(customerDTO).block();
}
And for handling errors, the WebClient throws WebClientResponseException and you can handle it in #RestControllerAdvice something like below.
#ExceptionHandler(WebClientResponseException.class)
public ProblemDetail handleWebClientException(WebClientResponseException e) {
HttpStatusCode statusCode = e.getStatusCode();
var responseBody = e.getResponseBodyAs(<ExpctedResponseClass>.class);
String message = "Details based on response";
return ProblemDetail.forStatusAndDetail(statusCode, message);
}

How to read Long from DynamoDB

I am trying to access a DynamoDB table from a Java application where the key is a long integer. Reading this guide, https://docs.amazonaws.cn/en_us/amazondynamodb/latest/developerguide/DynamoDBMapper.DataTypes.html, it seems that I can cast my N (number in table) as Long or BigInteger. When I try to retrieve data in both cases, I get this exception:

Try the following in your Controller:
#RestController
class ContentController(private val contentService: ContentService)
Additionally, remove any #Service annotation that you might have in ContentService interface.

The problem seems to come from your ContentController as the stacktrace mentionned :
at com.bloggie.contentservice.controller.ContentController.getPublicContent(ContentController.kt:27) ~[classes/:na]
Also, ensure that your interface ContentService is implemented correctly.

You need to inject the beans if you're using earlier than Spring 4.3 Try below:
#RestController
#Validated
open class ContentController #Autowired constructor(
