检查@FeignClient注解中标识的微服务是否启动 原因:此处接口可以声明@@Component注入ioc容器;并且启动类注解@EnableFeignClients若声明了接口所扫描package范围;则需要对应加上否则feign调用不生效启动bean报错s。 OpenFeign是一个显示声明式的WebService客户端。使用OpenFeign能让编写Web Service客户端更...
You can use a method reference to refer to a constructor without instantiating the named class. This kind of method reference is known as aconstructor reference. Its syntax isclassName::new.classNamemust support object creation; it cannot name an abstract class or interface. Keywordnewnames the r...
The target and handler must return the same type, even if the handler always throws. (This might happen, for instance, because the handler is simulating afinallyclause). To create such a throwing handler, compose the handler creation logic withthrowException, in order to create a method handle...
