使用Undertow适配器合并Keycloak身份验证时出错

Question

我正在通过以Keycloak为例，在我的应用程序中将org.keycloak/keycloak-undertow-adapter用于SSO，并使用immutant-keycloak。

我从中更改了中间件功能（没有SSO，但是像魅力一样工作，]，>

(defn wrap-auth [handler]
  (let [backend (backends/session {:unauthorized-handler handle-unauthorized})]
    (.registerSessionListener session-manager session-management)
    (-> handler
        (wrap-authentication backend)
        (wrap-authorization backend)
        (wrap-access-rules {:rules [{:pattern #"^/favicon.ico$"
                                     :handler permit-all}
                                    {:pattern #"^/assets/.*"
                                     :handler permit-all}
                                    {:pattern #"^/css/.*"
                                     :handler permit-all}
                                    {:pattern #"^/js/.*"
                                     :handler permit-all}
                                    {:pattern #"^/auth/.*"
                                     :handler permit-all}
                                    {:pattern #"^/.*"
                                     :handler authenticated-access}]
                            :on-error on-error}))))
对此，

(defn wrap-auth [handler]
  (let [backend (backends/session {:unauthorized-handler handle-unauthorized})
        session-manager (InMemorySessionManager. "SESSION_MANAGER")
        deployment (KeycloakDeploymentBuilder/build (io/input-stream (io/resource "keycloak.json")))
        deployment-context (AdapterDeploymentContext. deployment)
        session-management (UndertowUserSessionManagement.)
        nodes-management (NodesRegistrationManagement.)
        auth-mechanisms [(CachedAuthenticatedSessionMechanism.)
                         (UndertowAuthenticationMechanism. deployment-context
                                                           session-management
                                                           nodes-management
                                                           -1
                                                           nil)]
        ]
    (.registerSessionListener session-manager session-management)
    (-> (undertow/create-http-handler handler)
        (AuthenticationCallHandler.)
        (AuthenticationMechanismsHandler. auth-mechanisms)
        (->> (UndertowAuthenticatedActionsHandler. deployment-context)
             (UndertowPreAuthActionsHandler. deployment-context session-management session-manager)
             (SecurityInitialHandler. AuthenticationMode/PRO_ACTIVE idm))
        (wrap-authentication handler backend)
        (wrap-authorization backend)
        (wrap-access-rules {:rules [{:pattern #"^/favicon.ico$"
                                     :handler permit-all}
                                    {:pattern #"^/assets/.*"
                                     :handler permit-all}
                                    {:pattern #"^/css/.*"
                                     :handler permit-all}
                                    {:pattern #"^/js/.*"
                                     :handler permit-all}
                                    {:pattern #"^/auth/.*"
                                     :handler permit-all}
                                    {:pattern #"^/.*"
                                     :handler authenticated-access}]
                            :on-error on-error}))))
...而且我像这样使用wrap-auth，

(defn wrap-base [handler]
  (-> ((:middleware defaults) handler)
      (wrap-defaults
        (-> site-defaults
            (assoc-in [:security :anti-forgery] false)
            (assoc-in  [:session :store] (ttl-memory-store (* 60 30)))))
      wrap-flash
      wrap-session
      wrap-auth
      wrap-internal-error))
现在，我遇到此错误，
