java - Keycloak Authenticator SPI 示例不起作用

Question

我关注了 walkthrough用于为 keycloak(版本 4.8.3)设置自定义身份 validator spi。我几乎只使用我从 here 得到的示例代码.我只改了pom所以我可以编译项目并使用 mvn clean install wildfly:deploy 部署它.它有效......我可以在 keycloak 中配置新的身份验证流程，更新浏览器流程并设置所需的操作。但是如果我想在我的应用程序中使用新的身份验证，我会收到以下消息:Invalid username or password .在控制台中，我得到以下输出:

我在 github 上查找了文件 DefaultAuthenticationFlow.java:194它似乎是一个 RuntimeException:

throw new RuntimeException("Unable to find factory for AuthenticatorFactory: " + model.getAuthenticator() + " did you forget to declare it in a META-INF/services file?");

我真的不知道该怎么办。我有来自示例项目的 META-INF/服务。

知道这里可能有什么问题吗？
更新:
这是我的身份。流量设置:

绑定(bind) » 浏览器流程:设置为测试
更新:
我将这样的东西用于我自己的身份 validator 。

对于谁想要一个例子:
https://github.com/mfandre/KeycloakSPI/
这个例子创建了一个 SPI 到用户存储......这个想法类似于在 LDAP 中对用户进行身份验证，但在这个例子中，我们将在 RestAPI 中进行身份验证并将用户带到 keycloak!
