我正在尝试使用Java客户端调用KeyCloak Admin API.无论我尝试哪种操作-创建领域,创建用户帐户等-我都会收到以下异常：

javax.ws.rs.ProcessingException: java.lang.NullPointerException at

org.keycloak.admin.client.resource.BearerAuthFilter.filter(BearerAuthFilter.java:53)

at

org.jboss.resteasy.client.jaxrs.internal.ClientInvocation.filterRequest(ClientInvocation.java:573)

at

org.jboss.resteasy.client.jaxrs.internal.ClientInvocation.invoke(ClientInvocation.java:438)

at

org.jboss.resteasy.client.jaxrs.internal.proxy.ClientInvoker.invoke(ClientInvoker.java:102)

at

org.jboss.resteasy.client.jaxrs.internal.proxy.ClientProxy.invoke(ClientProxy.java:76)

at com.sun.proxy.$Proxy214.create(Unknown Source)

我的KeyCloak代码看起来像这样…

Keycloak kc = KeycloakBuilder.builder().realm("master").clientId("admin-cli").username("admin") .password("password").serverUrl("http://localhost:8880/auth")

.resteasyClient(new ResteasyClientBuilder().connectionPoolSize(10).build()).build();

RealmRepresentation realm = new RealmRepresentation();

realm.setDisplayName(displayName);

realm.setDisplayNameHtml(displayName);

realm.setRealm(realmName);

realm.setEnabled(enabled);

kc.realms().create(realm);

在这一点上,我看到了异常.您对这里可能出什么问题有任何想法吗？我看到针对admin API的所有操作上的异常.我知道数据可用,因为我可以对admin API进行curl调用,并且工作正常.

curl -vki -H "Authorization: Bearer XXXXX" http://localhost:8880/auth/admin/realms/master

当我打电话时,我看到了预期的结果.使用Java客户端时,我只会失败.知道这里发生了什么吗？

更新

我增加了KeyCloak实例上的调试日志.尝试创建安全领域后,我看到以下消息. (注意：无论执行什么操作,我都会看到类似的错误)

更新2

似乎此问题与在Java EE容器中运行此代码有关.如果我在独立类中运行完全相同的代码,则可以正常工作.但是,如果我将代码复制并粘贴到servlet并尝试运行它,则会收到NullPointerException.遇到问题时,我正在Wildfly 13上运行代码.通过Arquillian运行集成测试时,我也看到此问题.我的假设是它必须与依赖项有关,但是我对需要更改的内容不知所措.
