从头搭建spring cloud + spring cloud alibaba踩坑日志<二>

融入gateway

在gateway项目中加入了spring-boot-starter-web依赖导致报错

Please set spring.main.web-application-type=reactive or remove spring-boot-starter-web dependency.
在引入gateway时出现路由失效的情况；

    gateway:
      routes:
         #路由ID，没有固定要求，但是要保证唯一，建议配合服务名
        - id: auth
          #uri: http://127.0.0.1:9080 认证中心的服务地址
          uri: lb://auth
          order: 8000
          predicates:
            - Path=/auth/**

使用http://127.0.0.1:9080地址路由时能正常路由，但是使用lb://auth无法路由 经查证是因为没有加入依赖导致

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-loadbalancer</artifactId>
