网关升级spring boot项目后，启动网关报错，具体报错信息如下:

第一个解决方法

去掉application.yml配置default-filters配置即可

spring:

cloud:

gateway:

discovery:

locator:

enabled: true

default-filters:

- name: Hystrix

args:

name : default

fallbackUri: 'forward:/defaultFallback'

第二个方法

自定义过滤器整合hystrix：重新实现一遍HystrixGatewayFilterFactory
