我有一个Keycloak 4.2.1服务器,并且我试图为其实现自定义的“ LoginFormsProvider”。我的目标是通过附加组件扩展到登录页面(freemarker),在本例中,它是一个简单的信息框。我想在Provider类中设置该框的内容。
我已经实现了另外两个自定义提供程序,并且它们运行良好(UserStorageProvider和EventListenerProvider)。这样我的.jar文件就被服务器找到了。
但是我对“ LoginFormsProvider”有疑问。服务器找不到提供者。请参阅下面的堆栈跟踪...
我在“ META-INF / services”路径中添加了一个文件“ org.keycloak.login.LoginFormsProviderFactory” 包和类名称为“ de.test.login.TestLoginFactory”(不带引号)。
这将导致我的提供程序的工厂类。 就像我为其他提供商所做的那样。
我的FactoryClass看起来像这样:
package de.test.login;
import java.util.LinkedHashMap;
import java.util.Map;
import org.jboss.logging.Logger;
import org.keycloak.Config.Scope;
import org.keycloak.freemarker.FreeMarkerUtil;
import org.keycloak.login.LoginFormsProvider;
import org.keycloak.login.LoginFormsProviderFactory;
import org.keycloak.models.KeycloakSession;
import org.keycloak.models.KeycloakSessionFactory;
import org.keycloak.provider.ServerInfoAwareProviderFactory;
public class TestLoginFactory implements LoginFormsProviderFactory{
private FreeMarkerUtil freeMarker;
private final static String PROVIDER = "test-login-provider";
@Override
public LoginFormsProvider create(KeycloakSession session) {
return new TestLoginProvider(session, freeMarker);
}
@Override
public void init(Scope config) {
freeMarker = new FreeMarkerUtil();
}
@Override
public void postInit(KeycloakSessionFactory factory) {
}
@Override
public void close() {
freeMarker = null;
}
@Override
public String getId() {
return PROVIDER;
}
}
此处是Provider类:
package de.test.login;
import javax.ws.rs.core.Response;
import org.jboss.logging.Logger;
import org.keycloak.freemarker.FreeMarkerUtil;
import org.keycloak.login.freemarker.FreeMarkerLoginFormsProvider;
import org.keycloak.models.KeycloakSession;
public class TestLoginProvider extends FreeMarkerLoginFormsProvider{
final private Logger logger = Logger.getLogger(this.getClass());
public TestLoginProvider(KeycloakSession session, FreeMarkerUtil freeMarker) {
super(session, freeMarker);
}
@Override
public Response createLogin(){
logger.info("do crazy stuff");
Response response = super.createLogin();
return response;
}
}
在我的standalone.xml中,我在其他spi声明附近添加了一个spi声明。
<spi name="login">
<default-provider>test-login-provider</default-provider>
</spi>
这是standalone.xml的完整部分:
...
<subsystem xmlns="urn:jboss:domain:keycloak-server:1.1">

现在,当我启动服务器时,我得到了下面的stacktrace。我不知道他为什么找不到工厂类?
我检查了.jar文件,但没有丢失任何文件。

如果你们需要更多信息,请告诉我。
我忘了东西还是有错误吗?
非常感谢您的帮助。
亲切的问候
答案 0 :(得分:1)
您使用什么版本的密钥斗篷?如果它是更高版本(1.x以上)之一,则您似乎在类中使用了“错误”的导入语句。
请尝试更新所有必要的依赖项,看看是否可行。
