这个注解类会根据是否存在ExecutableValidator类和ValidationProvider文件确定是否注入，ValidationProvider文件在hibernate-validator 的jar包配置里。正常情况下引入spring-boot-strater后 会引入ExecutableValidator类，和hibernate-validator包。这就导致debug开启时一直会爆
trationDelegate$BeanPostProcessorChecker : Bean 'popNotifyServiceFacade' of type [com.alibaba.dubbo.config.spring.ReferenceBean] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)
这种错误。解决方案有两种,1.踢掉validation的依赖，2.踢掉hibernate-validation的依赖。
