# 计划 01: 网关领域实体

## 目标

创建从 fengling-gateway 项目迁移的网关路由领域实体。

**目的:** 在 Platform 领域层建立网关聚合，包含符合 YARP 要求的实体。

**输出:** 新建 GatewayAggregate 文件夹中的三个实体文件。

## 上下文

@Fengling.Platform.Domain/AggregatesModel/ (现有 Tenant 聚合结构)
@../fengling-gateway/src/Models/ (源实体)

## 任务

<task type="auto">
  <name>任务 1: 创建 GatewayEnums</name>
  <files>Fengling.Platform.Domain/AggregatesModel/GatewayAggregate/GatewayEnums.cs</files>
  <action>
创建网关实体使用的枚举类型：
- RouteStatus (Active=1, Inactive=0)
- InstanceHealth (Healthy=1, Unhealthy=0)
- InstanceStatus (Active=1, Inactive=0)

参考现有: Fengling.Platform.Domain/AggregatesModel/TenantAggregate/Tenant.cs
  </action>
  <verify>文件可编译，枚举可访问</verify>
  <done>GatewayEnums.cs 已创建，包含 RouteStatus, InstanceHealth, InstanceStatus</done>
</task>

<task type="auto">
  <name>任务 2: 创建 GwTenant 实体</name>
  <files>Fengling.Platform.Domain/AggregatesModel/GatewayAggregate/GwTenant.cs</files>
  <action>
创建 GwTenant 实体，包含：
- Id (long), TenantCode (string), TenantName (string)
- Status (int), IsDeleted (bool), Version (int)
- CreatedTime, UpdatedTime, CreatedBy, UpdatedBy

参考源: ../fengling-gateway/src/Models/GwTenant.cs
参考模式: Fengling.Platform.Domain/AggregatesModel/TenantAggregate/Tenant.cs
  </action>
  <verify>dotnet build 通过</verify>
  <done>GwTenant 实体包含 Id, TenantCode, TenantName, Status 字段</done>
</task>

<task type="auto">
  <name>任务 3: 创建 GwTenantRoute 实体</name>
  <files>Fengling.Platform.Domain/AggregatesModel/GatewayAggregate/GwTenantRoute.cs</files>
  <action>
创建 GwTenantRoute 实体，包含：
- Id (long), TenantCode (string), ServiceName (string)
- ClusterId (string), PathPattern (string), Priority (int)
- Status (int), IsGlobal (bool)
- IsDeleted (bool), Version (int)
- CreatedTime, UpdatedTime, CreatedBy, UpdatedBy

参考源: ../fengling-gateway/src/Models/GwTenantRoute.cs
  </action>
  <verify>dotnet build 通过</verify>
  <done>GwTenantRoute 实体包含路由配置字段</done>
</task>

<task type="auto">
  <name>任务 4: 创建 GwServiceInstance 实体</name>
  <files>Fengling.Platform.Domain/AggregatesModel/GatewayAggregate/GwServiceInstance.cs</files>
  <action>
创建 GwServiceInstance 实体，包含：
- Id (long), ClusterId (string), DestinationId (string)
- Address (string), Health (int), Weight (int)
- Status (int)
- IsDeleted (bool), Version (int)
- CreatedTime, UpdatedTime, CreatedBy, UpdatedBy

参考源: ../fengling-gateway/src/Models/GwServiceInstance.cs
  </action>
  <verify>dotnet build 通过</verify>
  <done>GwServiceInstance 实体包含实例管理字段</done>
</task>

</tasks>

## 验证

- [ ] 所有 4 个实体文件已创建
- [ ] Build 无错误通过
- [ ] 实体遵循 Platform 约定 (long ID, PascalCase, 时间戳)

## 成功标准

领域实体准备好进行基础设施层实现。
