Spring zuul项目创建 路由转发，排除和自定义

下面是创建一个API网关转发端

spring:
  application:
    name: api-gateway
  cloud:
    config:
      discovery:
        enabled: true
        service-id: CONFIG
      profile: dev

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/
    registryFetchIntervalSeconds: 3000
    leaseRenewalIntervalInSeconds: 3

上面要关联到gitee上的api-gateway-dev.yml

此时调demo应用某个接口时。

原应用接口http://localhost:8828/demoController/ceshi就可以用

http://localhost:9000/demo/demoController/ceshi访问了。

自定义路由

比如把上面的地址http://localhost:9000/demo/demoController/ceshi   改为  http://localhost:9000/demoController/myDemo/ceshi

myDmeo，是自定义名

serviceId,是eureka上的应用id

zuul:
  routes:
    myDemo:
      path: /myDemo/**
      serviceId: demo

或这种简洁写法

zuul:
  routes:
    #简洁写法 demo应用接口路由到myDemo下
    demo: /myDemo/**

查看所有路由规则

需要增加下面配置

management:
  security:
    enabled: false

访问  http://localhost:9000/application/routes

屏蔽接口

zuul:
  routes:
    demo: /myDemo/**
  #正则写法 屏蔽接口
  ignored-patterns:
    - /demo/demoController/ceshi
    - /myDemo/demoController/ceshi

或

zuul:
  routes:
    demo: /myDemo/**
  #正则写法 屏蔽接口
  ignored-patterns:
    - /**/demoController/ceshi
