springcloud-GateWay使用

话不多说，直接开干。

　　1.创建 网关模块。

　　2.添加依赖

    <dependencies>
        <!--   gateway     -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>cn.aib.springcloud</groupId>
            <artifactId>springclud-api-common</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
    </dependencies>

　　注意：网关不需要下面两个依赖：

                <!--   web Gateway不需要web依赖     -->
                <dependency>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-web</artifactId>
                </dependency>
                <dependency>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-actuator</artifactId>
                </dependency>

　　3.添加配置

server:
  port: 9527
spring:
  application:
    name: cloud-gateway
  cloud:
    gateway:
      discovery:
        locator:
          enabled: true  #开启注册中心路由功能
      #          lower-case-service-id: true
      routes:
        - id: payment_routh #路由ID
          #          uri: http://localhost:8001  or payment_routh   #路由要转发的URI地址
          uri: http://localhost:8001
          predicates:
            - Path=/payment/get/**  #URI匹配规则
        - id: payment_routh2
          #          uri: http://localhost:8001  or lb://cloud-payment-service
          uri: http://localhost:8001
          predicates:
            - Path=/payment/myrule/**
eureka:
  instance:
    hostname: cloud-gateway-service
  client:
    service-url:
      register-with-eureka: true
      fetch-registry: true
      defaultZone: http://eureka7001.com:7001/eureka #,http://eureka7002.com:7002/eureka

　　4.主启动

@SpringBootApplication
@EnableEurekaClient
public class GateWayApplication {
    public static void main(String[] args) {
        SpringApplication.run(GateWayApplication.class, args);
    }
}

　　5.测试
