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在 org.keycloak.admin.client.resource.BearerAuthFilter.filter(BearerAuthFilter.java:53) 在 org.jboss.resteasy.client.jaxrs.internal.ClientInvocation.filterRequest(ClientInvocation.java:573) 在 org.jboss.resteasy.client.jaxrs.internal.ClientInvocation.invoke(ClientInvocation.java:438) 在 org.jboss.resteasy.client.jaxrs.internal.proxy.ClientInvoker.invoke(ClientInvoker.java:102) 在 org.jboss.resteasy.client.jaxrs.internal.proxy.ClientProxy.invoke(ClientProxy.java:76) com.sun.proxy。$ Proxy214.create(未知来源)
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);
这是我看到的异常。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,并且可以正常工作。
curl -vki -H "Authorization: Bearer XXXXX" http://localhost:8880/auth/admin/realms/master
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?
UPDATE
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。
答案 0 :(得分:4)
如果要保留对WildFly 13的Java EE 8支持,只需创建空的jackson提供程序:
public class CustomJacksonProvider extends ResteasyJackson2Provider {
}
并使用register()
的{{1}}方法将其添加到KeyCloak构建器中:
ResteasyClientBuilder
您还需要添加一些轻松的依赖项(例如Keycloak kc = KeycloakBuilder.builder()
.realm("master")
.clientId("admin-cli")
.username("admin")
.password("password")
.serverUrl("http://localhost:8880/auth")
.resteasyClient(new ResteasyClientBuilder().connectionPoolSize(10).register(new CustomJacksonProvider()).build())
.build();
)才能使用scope=provided
和ResteasyClientBuilder
:
ResteasyClientBuilder
答案 1 :(得分:2)
简单地(可能甚至太多)放置一个与Resteasy库相关的错误,其中JsonBindingProvider
的优先级高于ResteasyJackson2Provider
,这使得json负载中的某些属性无法映射适当地,他们的价值观迷失了。因此,NullPointerException。
如果您使用的是JBoss或WildFly,最简单的解决方案应该是从resteasy-json-binding-provider
文件的部署中排除jboss-deployment-structure.xml
模块:
<jboss-deployment-structure>
<deployment>
<exclusions>
<module name="org.jboss.resteasy.resteasy-json-binding-provider"/>
</exclusions>
</deployment>
</jboss-deployment-structure>
答案 2 :(得分:0)
您没有授权标头。请尝试
Keycloak kc = KeycloakBuilder.builder().realm("master").clientId("admin-cli").username("admin") .password("password").authorization("authorization").serverUrl("http://localhost:8880/auth")
.resteasyClient(new ResteasyClientBuilder().connectionPoolSize(10).build()).build();
请注意
.authorization("authorization")
答案 3 :(得分:0)
解决了!!显然,我的Wildfly 13.0实例已配置为启用Java EE 8支持。这似乎是问题的根本原因,因为删除该标志使所有测试用例都能按预期工作。不知道为什么会出现问题,但这绝对是潜在的问题。
