1、排除依赖

spring-boot-starter-webflux

 2、添加依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>

3、yml进行配置

spring:
  cloud:
    nacos:
      server-addr: 127.0.0.1:8848
    gateway:
      discovery:
        locator:
          enabled: true
      routes:
        - id: aliyunOS
          uri: lb://aliyunOS
          predicates:
            - Path=/aliyun/**
        - id: service-cms
          uri: lb://service-cms
          predicates:
            - Path=/cms/**
        - id: service-edu
          uri: lb://service-edu
          predicates:
            - Path=/edu/**
        - id: service-msm
          uri: lb://service-msm
          predicates:
           - Path=/msm/**
        - id: service-order
          uri: lb://service-order
          predicates:
            - Path=/order/**
        - id: service-sta
          uri: lb://service-sta
          predicates:
            - Path=/sta/**
        - id: service-ucenter
          uri: lb://service-ucenter
          predicates:
            - Path=/ucenter/**
  datasource:
    driver-class-name: com.mysql.jdbc.Driver

        #最大空闲
        max-idle: 8
        #最小空闲
        min-idle: 0
        #连接超时时间
        timeout: 10000
    cache:
      redis:
        time-to-live: 36000

mybatis-plus:

    db-config:
      logic-delete-field: deleted
      logic-delete-value: 1
      logic-not-delete-value: 0

#feign:
#  hystrix:

##    root: INFO

 4、启动类添加

@EnableDiscoveryClient

5、测试
