keycloak 事件监听的spi开发测试

1. 新建简单maven工程

注意keycloak包的scope为provided
如

<dependency>
            <groupId>org.keycloak</groupId>
            <artifactId>keycloak-services</artifactId>
            <version>4.8.3.Final</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.keycloak</groupId>
            <artifactId>keycloak-core</artifactId>
            <version>4.8.3.Final</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.keycloak</groupId>
            <artifactId>keycloak-server-spi</artifactId>
            <version>4.8.3.Final</version>
            <scope>provided</scope>
        </dependency>
        ...

• 如要相关依赖打肥包
  可以使用插件maven-assembly-plugin

2. spi开发

• 实现EventListenerProvider

public class MyEventListenerProvider implements EventListenerProvider{
  org.slf4j.Logger log = LoggerFactory.getLogger(MyEventListenerProvider.class);
  private List<Event> events;

  public MyEventListenerProvider(List<Event> events) {
      System.out.println("events构造方法");
      this.events = events;
  }

  @Override
  public void onEvent(Event event) {
      System.out.println("deng"+event.getTime()+" realmId:"+event.getRealmId()+" type:"+event.getType().name());
      log.info(event.getClientId());
      events.add(event);
  }

  @Override
  public void close() {

  }

  @Override
  public void onEvent(AdminEvent event, boolean includeRepresentation) {
      // Assume this implementation just ignores admin events
      System.out.println("deng"+event.getTime());
  }

  
}

2.实现EventListenerProviderFactory

public class MyEventListenerProviderFactory implements EventListenerProviderFactory {

    private List<Event> events;

    public String getId() {
        return "my-deng";
    }

    public void init(Config.Scope config) {
        
        System.out.println("init " );
        events = new LinkedList();
    }

    public void postInit(KeycloakSessionFactory factory) {
    }

    public EventListenerProvider create(KeycloakSession session) {
        System.out.println("create "+session.getContext().getContextPath());
        return new MyEventListenerProvider(events);
    }

    public void close() {
    }

    
    }

3. 建立META-INF\services文件夹
   以实现的接口全限定类名为文件名，文件内容为具体实现类的全限定类名
   文件名称：org.keycloak.events.EventListenerProviderFactory
   内容： com.dengji85.keycloak.spi.MyEventListenerProviderFactory

3. 部署

将打好的jar包copy到keycloak主目录\standalone\deployments
这个目录会自动部署也支持热部署
在管理控制台配置事件监听器
