demo介绍

1. 网关

1.1.网关pom.xml配置

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

1.2.网关application.yml

spring:
      cloud:
        gateway:
          routes:
            - id: demo                          #路由的唯一id
              uri: http://localhost:8080        #指向注册中心的服务，使用lb:// 加上ServiceName，当然也可以通过http://localhost:8080指向
              predicates:                       #要进行的断言
                - Path=/d1/**                 #路径匹配
                - Header=auth-name              #请求头匹配
                - Header=auth-token
              filters:                          #过滤器
                - StripPrefix=1                 #截取url，本例中就是会把/demo截掉，后面的部分才是转发的url
    server:
      port: 80

2. 被转发的demo服务器配置

2.1.pom.xml配置

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
            </dependency>

2.2.application.yml

server:
      port: 8080

3. 成果展示

1）启动网关服务器gateway和测试服务器demo

2）打开postman，通过网关服务器gateway访问demo服务器，配置请求头auth-name和auth-token

springcloud-gateway的简单路由转发和请求过滤就完成了。
