 解决思路：首先我们找到zuul里的application.yml

原yml

ribbon:
  ReadTimeout: 2400000
  ConnectTimeout: 2400000
#security:
#ignored: /static/favicon.ico

sino.allow.userType: USER_TYPE01,00,5

sino:
  login:
    errorMaxCount: 5

#是否启用referer匹配，防止未登录直接访问前端页面上的字段，建议门户开启
referer:
  matching:
    enabled: true

删除注释后yml

hystrix:
  command:
    default:
      execution:
        isolation:
          semaphore:
            maxConcurrentRequests: 500
          thread:
            timeoutInMilliseconds: 1200000
ribbon:
  ReadTimeout: 2400000
  ConnectTimeout: 2400000


sino.allow.userType: USER_TYPE01,00,5

sino:
  login:
    errorMaxCount: 5


referer:
  matching:
    enabled: true

 删除application.yml里的#注释再重新试一下，就好啦~

需要注意yml里特别注重格式，多个空格少个空格都不行。
