DubboHolderListener中Thread的启动时间问题

3

DubboHolderListener中onApplicationEvent(ApplicationEvent event)方法启动守护线程是通过event instanceof ContextRefreshedEvent为标准启动的，但是这个判断会导致spring boot都为完全启动，dubbo服务更是还未开始启动就创建一个常驻线程，这样会导致spring启动过程中有其他异常时，程序会一直挂起，不会自动退出，这里个人觉得事件判断应该采用event instanceof ContextRefreshedEvent，这样才能不干扰spring-boot容器的初始化启动。
