Spring GraphQL - 可选授权

我目前正在使用Spring Boot Starter和GraphQL Java Tools在我的Spring应用程序中使用GraphQL . 只要我授权graphql endpoints ，它就可以与我的授权过滤器一起使用 . 现在我想向公众开放某些突变或查询（因此无需授权），这就是我绊倒的地方 . 如何打开graphql endpoints 但仍能使用Spring安全性的 @PreAuthorize 注释进行方法级别授权？换句话说：是否可以在 endpoints 上进行"optional"授权？

这是我的配置：

@Override
protected void configure(HttpSecurity http) throws Exception {
    log.debug("configureHttpSecurity");

    // Only authorize the request if it is NOT in the permitAllEndpoints AND matches API_ROOT_URL OR
    // MESSAGING_ROOT_URL
    List<RequestMatcher> requestMatchers = new ArrayList<>();
    requestMatchers.add(new SkipPathRequestMatcher(permitAllEndpointList, API_ROOT_URL));
    requestMatchers.add(new AntPathRequestMatcher(MESSAGING_ROOT_URL));
    OrRequestMatcher apiMatcher = new OrRequestMatcher(requestMatchers);

    http.csrf().disable()
                .sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            .and()
                .authorizeRequests()
                .antMatchers(permitAllEndpointList.toArray(new String[0]))
                .permitAll()
            .and()
                .authorizeRequests()
                .antMatchers(API_ROOT_URL, MESSAGING_ROOT_URL)
                .authenticated()
            .and()
                .addFilterBefore(new CustomCorsFilter(),
                        UsernamePasswordAuthenticationFilter.class)
                .addFilterBefore(new AuthenticationFilter(authenticationManager()),
                        UsernamePasswordAuthenticationFilter.class)
                .addFilterBefore(new AuthorizationFilter(apiMatcher),
                        UsernamePasswordAuthenticationFilter.class);
}

apiMatcher 将打开某些REST endpoints . 这是我的 AuthorizationFilter ：

@Override
public Authentication attemptAuthentication(HttpServletRequest httpServletRequest,
                                            HttpServletResponse httpServletResponse)
        throws AuthenticationException, IOException, ServletException {
    try {
        String authorization = httpServletRequest.getHeader("Authorization");
        if (authorization != null && authorization.startsWith("Bearer ")) {
            return getAuthentication(authorization.replace("Bearer ", ""));
        }
    } catch (ExecutionException e) {
        httpServletResponse.sendError(HttpServletResponse.SC_FORBIDDEN,"The provided token was either not valid or is already expired!");
        return null;
    } catch (IOException | InterruptedException e) {
        httpServletResponse.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR,"There was a problem verifying the supplied token!");
        return null;
    }
    httpServletResponse.sendError(HttpServletResponse.SC_FORBIDDEN, "Unauthorized");
    return null;
}

如果我没有在 attemptAuthentication 结束时发送错误，我将能够访问不应该打开的REST endpoints . 此外，如果我只允许GraphQL endpoints ，那么即使我提供了有效的JWT，也不会发生授权，因此每个 @PreAuthorize 都会失败 . 可能我的方法已经错了 . 如果是这种情况，请告诉我 .
