Я пытаюсь реализовать аутентификацию на основе токена на основе токена на отдыхе, который я разработал с помощью Spring Boot. Идея состоит в том, что клиент включает токен JWT с любым запросом, а фильтр извлекает его из запроса и устанавливает SecurityContext с соответствующим объектом аутентификации на основе содержимого токена. Затем запрос маршрутизируется как обычно и защищен с помощью @PreAuthorize по отображаемому методу.
Моя конфигурация безопасности выглядит следующим образом:
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private JWTTokenAuthenticationService authenticationService;
@Override
protected void configure(HttpSecurity http) throws Exception
{
http
.csrf().disable()
.headers().addHeaderWriter(new XFrameOptionsHeaderWriter(XFrameOptionsMode.SAMEORIGIN))
.and()
.authorizeRequests()
.antMatchers("/auth/**").permitAll()
.antMatchers("/api/**").authenticated()
.and()
.addFilterBefore(new StatelessAuthenticationFilter(authenticationService), UsernamePasswordAuthenticationFilter.class);
}
С фильтром без состояния, который расширяет GenericFilterBean, определяется следующим образом:
public class StatelessAuthenticationFilter extends GenericFilterBean {
private static Logger logger = Logger.getLogger(StatelessAuthenticationFilter.class);
private JWTTokenAuthenticationService authenticationservice;
public StatelessAuthenticationFilter(JWTTokenAuthenticationService authenticationService)
{
this.authenticationservice = authenticationService;
}
@Override
public void doFilter( ServletRequest request,
ServletResponse response,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpRequest = (HttpServletRequest) request;
Authentication authentication = authenticationservice.getAuthentication(httpRequest);
SecurityContextHolder.getContext().setAuthentication(authentication);
logger.info("===== Security Context before request =====");
logger.info("Request for: " + httpRequest.getRequestURI());
logger.info(SecurityContextHolder.getContext().getAuthentication());
logger.info("===========================================");
chain.doFilter(request, response);
SecurityContextHolder.getContext().setAuthentication(null);
logger.info("===== Security Context after request =====");
logger.info("Request for: " + httpRequest.getRequestURI());
logger.info(SecurityContextHolder.getContext().getAuthentication());
logger.info("===========================================");
}
}
Конечная точка определяется следующим образом:
@PreAuthorize("hasAuthority('user')")
@RequestMapping ( value="/api/attachments/{attachmentId}/{fileName:.+}",
method = RequestMethod.GET)
public ResponseEntity<byte[]> getAttachedDocumentEndpoint(@PathVariable String attachmentId, @PathVariable String fileName)
{
logger.info("GET called for /attachments/" + attachmentId + "/" + fileName);
// do something to get the file, and return ResponseEntity<byte[]> object
}
Когда вы выполняете GET on/api/attachments/someattachment/somefilename, включая токен, я вижу, что фильтр вызывается дважды, по-видимому, с токеном и один раз без него. Но оставшийся контроллер, сопоставленный с запросом, вызывается только один раз.

Что здесь происходит?
Редактировать:
Это еще более странно, чем я думал - реализация простой конечной точки, которая просто возвращает простое сообщение, отображает ожидаемое поведение - похоже, только когда я пытаюсь вернуть данные как ResponseEntity, как указано выше, эта проблема возникает.
Конечная точка:
@PreAuthorize("hasAuthority('user')")
@RequestMapping("/api/userHelloWorld")
public String userHelloWorld()
{
return "Hello Secure User World";
}
Вывод, показывающий один вызов фильтра (с дополнительной отладкой):
