介绍

本小节介绍如何在本地通过 Choerodon 来进行微服务开发。

启动todo 服务

进入choerodon-todo-service目录下，运行以下命令启动本地项目

  1. mvn clean spring-boot:run
- 本地开发服务，如果不调用其他服务，则可以不需要启动注册中心，在TodoServiceApplication中不需要添加@EnableEurekaClient 注解。- 如果不需要测试到kafka相关的，可以将kafka的相关的依赖注释掉。提交时再打开。

服务注册

在TodoServiceApplication中添加@EnableEurekaClient 注解。

在application.yml中添加关于Eureka的配置

  1. eureka:
  2.   instance:
  3.     preferIpAddress: true
  4.     leaseRenewalIntervalInSeconds: 1
  5.     leaseExpirationDurationInSeconds: 3
  6.   client:
  7.     serviceUrl:
  8.       defaultZone: http://localhost:8000/eureka/

如果需要自动将该服务在线上添加到路由列表中，需在xxx.infra.util包下创建拓展数据配置类，并继承ExtraDataManager，以用于自动初始化路由。示例如下：

  1. @ChoerodonExtraData
  2. public class CustomExtraDataManager implements ExtraDataManager {
  3.     @Override
  4.     public ExtraData getData() {
  5.         ChoerodonRouteData choerodonRouteData = new ChoerodonRouteData();
  6.         choerodonRouteData.setName("todo");
  7.         choerodonRouteData.setPath("/todo/**");
  8.         choerodonRouteData.setServiceId("choerodon-todo-service");
  9.         extraData.put(ExtraData.ZUUL_ROUTE_DATA, choerodonRouteData);
  10.         return extraData;
  11.     }
  12. }

或者以管理员权限登录平台，在管理 -> 微服务管理 -> 路由管理 中添加对应服务的路由信息。

接口权限

Choerodon 的接口权限遵循RBAC。需要在接口上添加@Permission()注解。

包含如下参数。

参数名说明
level接口层级，ResourceLevel.SITE，ResourceLevel.ORGANIZATION，ResourceLevel.PROJECT三种
permissionLogin登录允许访问，默认为false
permissionPublic公开接口，默认为false

其中如果层级为组织层或项目层，则接口的mapping 中必须包含organization_id 或 project_id 作为变量。否则gateway-helper校验时不会识别该权限。

本地测试

由于Choerodon 包含的服务比较多和依赖的组件较多。一般不会在本地将所有的服务都启动，只会根据自己的需要启动对应的服务。建议在服务器运行一整套环境，本地做服务的单体测试，服务器上进行集成测试。

1. 如果不需要获取当前登录的用户信息，在TodoServiceApplication中不需要添加@EnableChoerodonResourceServer 注解。然后直接通过postman 或其他接口测试工具对服务提供的接口进行测试。

2. 如果需要获取当前登录的用户信息，则需要在本地启动如下服务，进行登录。

  • register-server
  • api-gateway
  • gateway-helper
  • oauth-server
    3. 然后通过api-gateway 的输出日志，获取登录用户的 jwt_token。然后添加请求头。
  1. {
  2.   "Jwt_Token": jwt_token
  3. }

启动相关服务

如果需要启动其他模块，可以在github上获取到对应服务的最新代码，克隆到本地，将./src/main/resources/application.yml 复制一份出来，修改里面的默认值。根据本地环境信息，修改数据库和kafka连接。

  1. $ cp ./src/main/resources/application.yml ./src/main/resources/application-default.yml
  2. $ mvn clean spring-boot:run

这里提供一份docker-compose.yaml仅供参考，具体根据配置修改本地程序的配置。服务启动之前，请确保iam-service 和 manager-service 的数据库已初始化完成。
