检测激活/就绪执行器endpoint执行并收集其结果以将其发送到endpoint

Question

我在Kubernetes上部署了带有执行器的Spring Boot 2.3.1应用程序，对应的K8s探针映射到执行器endpoint上：

livenessProbe:
  httpGet:
    path: /actuator/health/liveness
    ...

readinessProbe:
  httpGet:
    path: /actuator/health/readiness
    ...

Answer 1

这可能不是解决你问题的最优雅的方法，但会起作用。

只需截取执行器调用，并在响应发送后执行您需要执行的操作。

@Component
public class ActuatorHandlerInterceptorAdapter extends HandlerInterceptorAdapter {

  private static final Logger logger = LoggerFactory
      .getLogger(ActuatorHandlerInterceptorAdapter.class);

  @Override
  public void afterCompletion(HttpServletRequest request,
      HttpServletResponse response, Object handler, Exception ex)
      throws Exception {
    if (request.getRequestURL().toString().contains("actuator/health/liveness")){
      System.out.println("Let's do something based on liveness response");
    }
    if (request.getRequestURL().toString().contains("actuator/health/readiness")){
      System.out.println("Let's do something based on readiness response");
    }
  }

}
