## 一、gateway案例1 ##

#### 1、导入依赖 ####

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

#### 2、添加配置文件 ####

spring:
      application:
        name: gateway-server
      cloud:
        gateway:
          routes:
            - id: order-server       // id名字一般和服务名相同
              uri: http://192.168.10.3:7888    // order-server 服务的部署地址和端口号
              predicates:                   // 断言
                - Path=/order/**            // path  http://127.0.0.1:9000/order/get/1
                                           //        http://192.168.10.3:7888/order/get/1
            - id: reposisitory-server
              uri: http://127.0.0.1:7002
              predicates:
                - Path=/rep/**
    server:
      port: 9000

3、创建启动类

## 二、gateway整合nacos注册中心 ##

#### 1、导入依赖 ####

<dependencies>
            <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>
        </dependencies>

#### 2、配置文件 ####

spring:
      application:
        name: gateway-server
      cloud:
        gateway:
          routes:
            - id: order-server
              uri: lb://order-server
              predicates:
                - Path=/order/**
            - id: reposisitory-server
              uri: lb://reposisitory-server
              predicates:
                - Path=/rep/**
        nacos:
          discovery:
            server-addr: 127.0.0.1:8848
    server:
      port: 9000

## 三、动态结合nacos注册中心 ##

#### 1、导入依赖 ####

#### 2、配置文件 ####

spring:
      application:
        name: gateway-server
      cloud:
        gateway:
          discovery:
            locator:
              enabled: true
        nacos:
          discovery:
            server-addr: 127.0.0.1:8848
    server:
      port: 9000

#### 3、注意：请求地址需要拼接微服务名字 ####
