@EnableFeignClients 注解

@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients(basePackages  = {"com.one"})
//@EnableFeignClients(basePackageClasses = {IUserFeign.class})
@ComponentScan( basePackages = { "com.one.*.api","com.one.*.controller"} )
public class PlatformAuthApplication {
    public static void main(String[] args) {
        SpringApplication.run(PlatformAuthApplication.class,args);
    }
}
@EnableFeignClients(basePackages  = {"com.one"})
@EnableFeignClients(basePackageClasses = {IUserFeign.class})
两者等价  
区别  
basePackages 包路径
basePackageClasses 类路径
