1.1、依赖-初体验

1、添加依赖

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

2、添加微服务的依赖

            <!-- SpringCloud 微服务 -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

3、在src/main/resources下添加bootstrap.yml

server:
  port: 8080

spring: 
  application:
    name: gateway
  cloud:
    gateway:
      routes:
        # 系统模块
        - id: guo-system
          uri: https://www.baidu.com
          predicates:
            - Path=/gateway
          filters:
            - StripPrefix=1

4、添加启动类测试

@SpringBootApplication
public class GatewayApplication {    

    public static void main(String[] args){
        SpringApplication.run(GatewayApplication.class, args);
    }
    
}

5、访问 http://localhost:8080/gateway 就会转发到 https://www.baidu.com/
