(一)搭建注册与配置中心CSE

  1. 从官网下载对应版本下载地址
  2. 解压文件,然后执行 cse.exe
  3. 访问 http://127.0.0.1:30103 则可看到 CSE 页面

(二)项目总pom文件

1. pom.xml 文件配置

  }
}

4. 主启动类

        <artifactId>spring-boot-maven-plugin</artifactId>
      </plugin>
    </plugins>
  </build>
</project>

2. bootstrap.yml 配置

server:
  port: 9090

spring:
  application:
    name: huawei-gateway
  cloud:
    servicecomb:
      discovery:
        enabled: true
        watch: false
        address: http://127.0.0.1:30100
        appName: hauweicloud-application
        serviceName: ${spring.application.name}
        version: 0.0.1
      config:
        serverType: kie
        serverAddr: http://127.0.0.1:30110


    gateway:
      routes:
        - id: consumer
          uri: lb://huawei-consumer
          filters:
            - name: governance
          predicates:
            - Path=/**

3. 主启动类

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

(六)验证

  1. 分别启动 huawei-provider、huawei-consumer 和 huawei-gateway
  2. 访问 http://localhost:9090/sayHello?name=huawei,返回 “Hello huawei, This is Spring cloud Huawei + CSE!” 则项目搭建成功。
