故事
我正在使用 keycloak 6.0.1。我有一个领域有两种类型的用户:管理员和普通用户。我需要一个可以区分它们的主题，因为登录名不同(3 个字段与 2 个字段)。因此，我想扩展提供程序 FreeMarkerLoginFormsProvider 以传递自定义参数。我正在使用 keycloak deployer 来部署我的 SPI。
问题
不幸的是，Keycloak 在部署时抛出异常:

我也尝试过模块方法，但后来我得到一个 NullPointerException:

我一直在关注官方文档。我的另一个自定义 Pbkdf2PasswordHashProvider 实际上工作得很好。我在这里遗漏了什么吗？

import org.keycloak.forms.login.freemarker.FreeMarkerLoginFormsProvider;
import org.keycloak.models.KeycloakSession;
import org.keycloak.theme.FreeMarkerUtil;
public class CustomFreeMarkerLoginFormsProvider extends FreeMarkerLoginFormsProvider {
public CustomFreeMarkerLoginFormsProvider(KeycloakSession session, FreeMarkerUtil freeMarker) {
super(session, freeMarker);
setAttribute("isAdmin", uriInfo.getPath().contains("admin"));
}
}
最佳答案
我在 FreeMarkerAccountProvider/FreeMarkerAccountProviderFactory 中遇到了类似的情况，并且收到了 java.lang.NoClassDefFoundError: org/keycloak/theme/FreeMarkerUtil .
这解决了问题 Keycloak plugin using keycloak-services .
因为我正在使用 Keycloak 部署程序注册我的提供商。它似乎并没有处理所有的依赖关系，所以我在 src/main/resources/META-INF 下创建了一个 jboss-deployment-structure.xml 文件和我的依赖关系。这里的例子 jboss-deployment- structure.xml .
我还不得不禁用现有的提供程序并激活我的。我通过在 <subsystem xmlns="urn:jboss:domain:keycloak-server:1.1"> 中将以下内容添加到我的 standalone.xlm 来做到这一点标签:
<spi name="account">
<provider name="freemarker" enabled="false"/>
<provider name="myfreemarker" enabled="true"/>
</spi>
