网关入门（一）

网关入门流程图

1、创建网关模块 网关服务目录结构

2、导入网关相关依赖

<!--网管依赖-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
<!--nacos服务注册发现-->
<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
<!--loadbalancer负载均衡器-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-loadbalancer</artifactId>
</dependency>

3、配置yaml文件

server:
  port: 10086
spring:
  application:
    name: hm-gateway
  profiles:
    active: dev
  cloud:
    nacos:
      server-addr: 114.116.45.207:8848
    gateway:
      routes:
        - id: item-service
          uri: lb://item-service
          predicates:
            - Path=/items/**,

访问item-service服务 可以使用http://localhost:10086/items/page
