访客 一、项目-New-Module
二、选择Maven-jdk-Next
三、修改Name为gateway-查看GroupId是否正确-Finish
四、修改pom.xml文件

bootstrap.yml配置文件展示

唯一要注意的是，每个环境的后缀都是不同的
dubbo:registry:#挂载到SpringCloud注册中心address:spring-cloud://localhostcloud:#订阅服务提供方的应用列表，订阅多个服务提供者使用","连接subscribed-services:bi-cloud-engine八、gateway服务功能测试
在common通用模块下pojo创建实体，service创建接口
User
packagecom.bi.cloud.pojo;importlombok.Data;importjava.io.Serializable;@DatapublicclassUserimplementsSerializable{privateStringusername;privateStringpassword;}UserService
packagecom.bi.cloud.service;importcom.bi.cloud.pojo.User;publicinterfaceUserService{UseruserInfo();}在engine模块下创建UserServiceImpl.class实现
packagecom.bi.cloud.service.Impl;importcom.bi.cloud.pojo.User;importcom.bi.cloud.service.UserService;importorg.apache.dubbo.config.annotation.Service;importorg.springframework.stereotype.Component;@Service@ComponentpublicclassUserServiceImplimplementsUserService{@OverridepublicUseruserInfo(){Useruser=newUser();user.setUsername("admin");user.setPassword("123456");returnuser;}}在gateway模块下创建com.bi.cloud.controller.UserController.class
UserController
packagecom.bi.cloud.controller;importcom.bi.cloud.pojo.User;importcom.bi.cloud.service.UserService;importorg.apache.dubbo.config.annotation.Reference;importorg.springframework.web.bind.annotation.PostMapping;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.bind.annotation.RestController;@RestController@RequestMapping("/api/user")publicclassUserController{@ReferenceprivateUserServiceuserService;@PostMapping("/userInfo")publicUseruserInfo(){returnuserService.userInfo();}}项目-Maven-Reloadproject重新编译，启动engine服务、gateway服务
postman工具测试接口（接口地址：http://localhost:8008/bi-gateway/api/user/userInfo）
返回测试数据，服务调用成功！！！
