一，导入依赖
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-gateway</artifactId>
    </dependency>
    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
    </dependency>
二、配置yml
server:
  port: 10010
logging:
  level:
    cn.itcast: debug
  pattern:
    dateformat: MM-dd HH:mm:ss:SSS
spring:
  application:
    name: gateway
  cloud:
    nacos:
      server-addr: localhost:8848 # nacos地址
    gateway:
      routes:
        - id: itemservice # 路由标示，必须唯一
          uri: lb://itemservice # 路由的目标地址
          predicates: # 路由断言，判断请求是否符合规则
            - Path=/item/** # 路径断言，判断路径是否是以/item开头，如果是则符合
        - id: orderservice
          uri: lb://orderservice
          predicates:
            - Path=/order/**,/pay/**
        - id: userservice
          uri: lb://userservice
          predicates:
            - Path=/user/**,/address/**
        - id: searchservice
          uri: lb://searchservice
          predicates:
            - Path=/search/**
      default-filters:
        - AddRequestHeader=authorization, 2//添加网关的请求头
      globalcors:
        add-to-simple-url-handler-mapping: true
        corsConfigurations:
          '[/**]':
            allowedOrigins:
                                 //请求地址
            allowedMethods:  //请求方式
              - "GET"
              - "POST"
              - "DELETE"
              - "PUT"
              - "OPTIONS"
            allowedHeaders: "*" # 允许在请求中携带的头信息
            allowCredentials: true # 是否允许携带cookie
            maxAge: 360000 # 这次跨域检测的有效期

三、创建引导类
