SpringCloud - Gateway 网关配置

1.导入pom依赖

<!--导入网关依赖-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
<!--服务注册/发现-->
<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>

2.将网关服务注册到注册中心

3.配置路由规则（关键）

spring:
  cloud:
    gateway:
      routes:
#        - id: test_route
#          uri: https://www.baidu.com
#          predicates:
#            - Query=url,baidu
#
#        - id: qq_route
#          uri: https://www.qq.com
#          predicates:
#            - Query=url,qq

        # 商品服务路由规则（uri: lb://gulimall-product，这边在注册中心配置的端口为 10000）
        # http://localhost:88/api/product/category/list/tree  需要转成  http://localhost:10000/product/category/list/tree
        - id: product_route
          uri: lb://gulimall-product
          predicates:
            - Path=/api/product/**
          filters:
            - RewritePath=/api/(?<segment>.*),/$\{segment}

        # 商品服务路由规则 
        # http://localhost:88/api/thirdparty/oss/policy  需要转成  http://localhost:30000/oss/policy
        - id: thirdparty_route
          uri: lb://gulimall-third-party
          predicates:
            - Path=/api/thirdparty/**
          filters:
            - RewritePath=/api/thirdparty/(?<segment>.*),/$\{segment}

        # 会员服务
        - id: member_route
          uri: lb://gulimall-member
          predicates:
            - Path=/api/member/**
          filters:
            - RewritePath=/api/(?<segment>.*),/$\{segment}

        # 前段项目,api
        # http://localhost:88/captcha.jpg  需要转成  http://localhost:8080/renren-fast/captcha.jpg
        - id: admin_route
          uri: lb://renren-fast
          predicates:
            - Path=/api/**
          filters:
            - RewritePath=/api/(?<segment>.*),/renren-fast/$\{segment}

        - id: gulimall_host_route
          uri: lb://gulimall-product
          predicates:
            - Host=**.gulimall.com
