一、项目结构
这里使用eureka作为注册中心,person和equipment两个web服务作为业务中台本例中会使用postman调用person服务person服务中调用equipment服务。
registry -- 注册中心(当前采用eureka)
person -- 人员服务person-api -- 人员相关api提供, 包括 req, resp, service 等person-biz -- 人员相关服务接口具体实现, 依赖person-apiperson-provider -- 人员相关微服务启动类, 依赖person-biz
equipment -- 设备服务equipment-api -- 设备相关api提供, 包括 req, resp, service 等equipment-biz -- 设备相关服务接口具体实现, 依赖equipment-apiequipment-provider -- 设备相关微服务启动类, 依赖equipment-biz源码下载地址欢迎star springboot-openfeign
二、registry – 注册中心(当前采用eureka)
1、application.yml
server:port: 8001 # 该服务端口eureka:instance:hostname: registry # eureka的实例名称client:registerWithEureka: false # false表示当前项目不以客户端注册到服务中心(因为该项目本身就是注册中心)fetchRegistry: false # false表示当前项目不需要从注册中心拉取服务配置(因为该项目本身就是注册中心)serviceUrl:defaultZone: http://localhost:8001/eureka/spring:application:name: server-registy # 当前项目的实例名称(很重要)2、核心pom.xml
!-- 引入eureka-server依赖 --dependencygroupIdorg.springframework.cloud/groupIdartifactIdspring-cloud-starter-netflix-eureka-server/artifactIdversion2.1.3.RELEASE/version/dependency!-- gson --dependencygroupIdcom.google.code.gson/groupIdartifactIdgson/artifactIdversion2.6.2/version/dependency3、主启动类RegistryApplication
SpringBootApplication
EnableEurekaServer
public class RegistryApplication {public static void main(String[] args) {SpringApplication.run(RegistryApplication.class, args);}
}三、person – 人员服务
1、application.yml
server:port: 8002spring:application:name: person-providereureka:client:serviceUrl:defaultZone: http://localhost:8001/eureka/feign:httpclient:enabled: true2、核心pom.xml

FeignClient(value person-provider)
public interface PersonFeign {/*** 根据id获取人员* param personReq* return*/PostMapping(/person/get)PersonResp get(PersonReq personReq);
}RestController
RequestMapping(value /person)
Slf4j
public class PersonController {Autowiredprivate EquipmentFeign equipmentFeign;/*** 获取人员* param personReq* return*/PostMapping(/get)public PersonResp get(Validated RequestBody PersonReq personReq) {PersonResp personResp new PersonResp();personResp.setId(personReq.getId());personResp.setAge(30);personResp.setName(Messi);EquipmentReq equipmentReq new EquipmentReq();equipmentReq.setId(personReq.getId());EquipmentResp equipmentResp equipmentFeign.get(equipmentReq);log.info(equipmentResp {}, equipmentResp);return personResp;}
}4、项目结构 四、equipment – 设备服务
1、application.yml
server:port: 8003spring:application:name: equipment-providereureka:client:serviceUrl:defaultZone: http://localhost:8001/eureka/2、核心pom.xml
cloud-equipment-api !-- openFeign --dependencygroupIdorg.springframework.cloud/groupIdartifactIdspring-cloud-starter-openfeign/artifactIdversion2.2.1.RELEASE/version/dependencycloud-equipment-biz
!-- 使用web --dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactIdversion2.2.1.RELEASE/version/dependency!-- equipment-api --dependencygroupIdtca/groupIdartifactIdcloud-equipment-api/artifactIdversion1.0.0/version/dependency!-- person-api --dependencygroupIdtca/groupIdartifactIdcloud-person-api/artifactIdversion1.0.0/version/dependencycloud-equipment-provider dependencygroupIdtca/groupIdartifactIdcloud-equipment-biz/artifactIdversion1.0.0/version/dependencydependencygroupIdorg.springframework.cloud/groupIdartifactIdspring-cloud-starter-netflix-eureka-client/artifactIdversion2.2.1.RELEASE/version/dependency3、EquipmentFeign和EquipmentController
FeignClient(value equipment-provider)
public interface EquipmentFeign {/*** 根据id获取人员* param equipmentReq* return*/PostMapping(/equipment/get)EquipmentResp get(EquipmentReq equipmentReq);
}RestController
RequestMapping(value /equipment)
Slf4j
public class EquipmentController {Autowiredprivate PersonFeign personFeign;/*** 获取人员* param equipmentReq* return*/PostMapping(/get)public EquipmentResp get(Validated RequestBody EquipmentReq equipmentReq) {EquipmentResp equipmentResp new EquipmentResp();equipmentResp.setId(equipmentReq.getId());equipmentResp.setName(平板设备);return equipmentResp;}
}4、项目结构 五、测试
分别启动这三个服务 利用postman访问localhost:8002/person/get其中body中id传不同参数进行测试 可以发现能够通过openfeign在微服务之间进行接口调用
