   * 本问题不相关
     * 建议
       * event不可能为null
       * invocation不可能为null
       * invocation.getInvocationStageTrace不可能为null
       * response不可能为null
       * 注册事件监听，可以让RegisterEvent实现BootListener接口，override onBeforeHandler方法，再`event.getScbEngine().getEventBus().register(this);`即可
         避免产生一个RegisterEvent的bean实例，又额外new了一个实例，new出来的实例还没办法使用spring注入
     * 问题
       * 方法还需要标记上`@AllowConcurrentEvents`，否则consume方法是不能并发的，会形成性能瓶颈
   * 本问题相关
     eventBus机制没有变化  
     有没有可能是打印代码有异常，建议在方法入口打个断点看看是什么情况
