小记 Demo

  1. 定义领域模型

    • AggregateRoot:定义 SalesOrder 作为聚合根,其中包括订单明细、客户信息、订单总额等。
    • Entity:定义如 OrderItem(订单项)、Inventory(库存)等实体。
    • Value Object:定义如 Address(地址)、Money(金额)等值对象。
  2. 建立仓储接口

    • 使用 ABP vNext 框架的仓储模式来实现数据的持久化。例如,为 SalesOrderInventory 等实体创建仓储接口,如 ISalesOrderRepositoryIInventoryRepository
  3. 实现领域服务

    • 设计领域服务来处理业务逻辑,例如 OrderingService 可以管理订单的创建、修改和取消等业务操作。
    • 设计 InventoryService 来管理库存,处理库存的检查、更新等操作。
  4. 应用服务层

    • 实现应用服务层来封装领域逻辑,向外提供接口(如 API)。这层将处理应用逻辑,如数据传输对象(DTOs)的映射和事务管理。
    • 使用 ABP vNext 的自动映射特性来简化实体与 DTO 之间的映射工作。
  5. 事件驱动

    • 在领域模型中使用领域事件(如 OrderCreatedEventInventoryChangedEvent)来响应业务事件,并触发进一步的业务逻辑,例如,当订单创建后发送通知或更新库存。
  6. 集成和测试

    • 使用 ABP vNext 的集成测试功能来验证各个模块的正确性。
    • 保证每个领域服务和应用服务都通过单元测试,确保功能正确且稳定。
  7. 前端集成

    • 如果你的系统需要前端界面,可以使用 ABP vNext 支持的 Angular、Blazor 或其他前端框架来构建用户界面,实现订单管理和库存管理的视图。
  8. 部署和维护

    • 将系统部署到适合的服务器或云环境。
    • 实施监控和日志记录,确保系统稳定运行并及时响应可能的问题。

 

  1. 定义领域实体

      首先,定义聚合根 SalesOrder 和相关实体 OrderItem

    

 1 using System;
 2 using System.Collections.Generic;
 3 using Volo.Abp.Domain.Entities.Auditing;
 4 
 5 public class SalesOrder : AuditedAggregateRoot<Guid>
 6 {
 7     public string CustomerName { get; set; }
 8     public List<OrderItem> Items { get; private set; } = new List<OrderItem>();
 9     public decimal TotalAmount { get; private set; }
10 
11     public SalesOrder(Guid id, string customerName) : base(id)
12     {
13         CustomerName = customerName;
14     }
15 
16     public void AddItem(string productName, decimal unitPrice, int quantity)
17     {
18         Items.Add(new OrderItem(Guid.NewGuid(), productName, unitPrice, quantity));
19         TotalAmount += unitPrice * quantity;
20     }
21 }
22 
23 public class OrderItem : Entity<Guid>
24 {
25     public string ProductName { get; private set; }
26     public decimal UnitPrice { get; private set; }
27     public int Quantity { get; private set; }
28 
29     public OrderItem(Guid id, string productName, decimal unitPrice, int quantity) : base(id)
30     {
31         ProductName = productName;
32         UnitPrice = unitPrice;
33         Quantity = quantity;
34     }
35 }
View Code

 

  

2. 定义仓储接口

创建仓储接口 ISalesOrderRepository,这将在 ABP vNext 的仓储基础设施上进行扩展。

 

1 using System;
2 using System.Threading.Tasks;
3 using Volo.Abp.Domain.Repositories;
4 
5 public interface ISalesOrderRepository : IRepository<SalesOrder, Guid>
6 {
7     Task<SalesOrder> FindByIdAsync(Guid id);
8     Task SaveAsync(SalesOrder order);
9 }
View Code

 

 

3. 实现应用服务

接下来,我们将实现一个简单的应用服务来处理订单的创建和项的添加。

 

 1 using System;
 2 using System.Threading.Tasks;
 3 using Volo.Abp.Application.Services;
 4 
 5 public class SalesOrderAppService : ApplicationService
 6 {
 7     private readonly ISalesOrderRepository _salesOrderRepository;
 8 
 9     public SalesOrderAppService(ISalesOrderRepository salesOrderRepository)
10     {
11         _salesOrderRepository = salesOrderRepository;
12     }
13 
14     public async Task<Guid> CreateOrderAsync(string customerName)
15     {
16         var order = new SalesOrder(Guid.NewGuid(), customerName);
17         await _salesOrderRepository.InsertAsync(order);
18         return order.Id;
19     }
20 
21     public async Task AddItemAsync(Guid orderId, string productName, decimal price, int quantity)
22     {
23         var order = await _salesOrderRepository.GetAsync(orderId);
24         order.AddItem(productName, price, quantity);
25         await _salesOrderRepository.UpdateAsync(order);
26     }
27 }
View Code

 

4. 定义库存实体

创建一个 Inventory 实体来表示库存信息。

 

 1 using System;
 2 using Volo.Abp.Domain.Entities.Auditing;
 3 
 4 public class Inventory : AuditedEntity<Guid>
 5 {
 6     public string ProductName { get; private set; }
 7     public int QuantityAvailable { get; private set; }
 8 
 9     public Inventory(Guid id, string productName, int quantityAvailable) : base(id)
10     {
11         ProductName = productName;
12         QuantityAvailable = quantityAvailable;
13     }
14 
15     public void ReduceStock(int quantity)
16     {
17         if (QuantityAvailable >= quantity)
18         {
19             QuantityAvailable -= quantity;
20         }
21         else
22         {
23             throw new InvalidOperationException("Insufficient stock available.");
24         }
25     }
26 
27     public void IncreaseStock(int quantity)
28     {
29         QuantityAvailable += quantity;
30     }
31 }
View Code

 

5. 库存服务

实现一个库存服务来处理库存更新的业务逻辑。

 

 1 using System;
 2 using System.Threading.Tasks;
 3 using Volo.Abp.Domain.Repositories;
 4 using Volo.Abp.Domain.Services;
 5 
 6 public class InventoryService : DomainService
 7 {
 8     private readonly IRepository<Inventory, Guid> _inventoryRepository;
 9 
10     public InventoryService(IRepository<Inventory, Guid> inventoryRepository)
11     {
12         _inventoryRepository = inventoryRepository;
13     }
14 
15     public async Task ReduceStockAsync(Guid inventoryId, int quantity)
16     {
17         var inventory = await _inventoryRepository.GetAsync(inventoryId);
18         inventory.ReduceStock(quantity);
19         await _inventoryRepository.UpdateAsync(inventory);
20     }
21 
22     public async Task IncreaseStockAsync(Guid inventoryId, int quantity)
23     {
24         var inventory = await _inventoryRepository.GetAsync(inventoryId);
25         inventory.IncreaseStock(quantity);
26         await _inventoryRepository.UpdateAsync(inventory);
27     }
28 }
View Code

 

6. 集成领域事件

使用 ABP vNext 框架的事件总线来发布和处理订单创建事件,进一步管理库存变更。

 

 1 using System;
 2 using System.Threading.Tasks;
 3 using Volo.Abp.DependencyInjection;
 4 using Volo.Abp.Domain.Entities.Events;
 5 using Volo.Abp.EventBus;
 6 using Volo.Abp.Uow;
 7 
 8 public class SalesOrderEventHandler : ILocalEventHandler<EntityCreatedEventData<SalesOrder>>, ITransientDependency
 9 {
10     private readonly InventoryService _inventoryService;
11 
12     public SalesOrderEventHandler(InventoryService inventoryService)
13     {
14         _inventoryService = inventoryService;
15     }
16 
17     [UnitOfWork]
18     public async Task HandleEventAsync(EntityCreatedEventData<SalesOrder> eventData)
19     {
20         foreach (var item in eventData.Entity.Items)
21         {
22             await _inventoryService.ReduceStockAsync(Guid.NewGuid(), item.Quantity); // Assume inventory ID is generated or fetched
23         }
24     }
25 }
View Code

 

 

7. 添加订单取消功能

首先,修改 SalesOrder 聚合根,增加一个取消订单的方法,同时引发一个订单取消的领域事件。

 

 1 using Volo.Abp.Domain.Entities.Events.Distributed;
 2 
 3 public class SalesOrderCancelledEvent : DistributedEntityEventData<SalesOrder>
 4 {
 5     public SalesOrderCancelledEvent(SalesOrder entity) : base(entity)
 6     {
 7     }
 8 }
 9 
10 public class SalesOrder : AuditedAggregateRoot<Guid>
11 {
12     // Existing properties and methods
13 
14     public bool IsCancelled { get; private set; }
15 
16     public void CancelOrder()
17     {
18         if (IsCancelled)
19             throw new InvalidOperationException("Order is already cancelled.");
20 
21         IsCancelled = true;
22         AddDistributedEvent(new SalesOrderCancelledEvent(this));
23     }
24 }
View Code

 

 

8. 处理订单取消事件

更新事件处理器来监听取消事件,并增加库存。

 

 1 public class SalesOrderCancelledEventHandler : ILocalEventHandler<SalesOrderCancelledEvent>, ITransientDependency
 2 {
 3     private readonly InventoryService _inventoryService;
 4 
 5     public SalesOrderCancelledEventHandler(InventoryService inventoryService)
 6     {
 7         _inventoryService = inventoryService;
 8     }
 9 
10     [UnitOfWork]
11     public async Task HandleEventAsync(SalesOrderCancelledEvent eventData)
12     {
13         foreach (var item in eventData.Entity.Items)
14         {
15             await _inventoryService.IncreaseStockAsync(Guid.NewGuid(), item.Quantity); // Assume inventory ID is generated or fetched
16         }
17     }
18 }
View Code

 

 

9. 添加查询服务

为了方便用户查询订单和库存状态,我们可以实现一些基础的查询服务。

 

 1 public class QueryService : ApplicationService
 2 {
 3     private readonly ISalesOrderRepository _salesOrderRepository;
 4     private readonly IRepository<Inventory, Guid> _inventoryRepository;
 5 
 6     public QueryService(ISalesOrderRepository salesOrderRepository, IRepository<Inventory, Guid> inventoryRepository)
 7     {
 8         _salesOrderRepository = salesOrderRepository;
 9         _inventoryRepository = inventoryRepository;
10     }
11 
12     public async Task<SalesOrderDto> GetOrderDetailsAsync(Guid orderId)
13     {
14         var order = await _salesOrderRepository.GetAsync(orderId);
15         return ObjectMapper.Map<SalesOrder, SalesOrderDto>(order);
16     }
17 
18     public async Task<InventoryDto> GetInventoryStatusAsync(Guid inventoryId)
19     {
20         var inventory = await _inventoryRepository.GetAsync(inventoryId);
21         return ObjectMapper.Map<Inventory, InventoryDto>(inventory);
22     }
23 }
View Code

 

 

10. DTO 定义

最后,我们需要定义一些数据传输对象(DTO)来传递数据。

 

 1 public class SalesOrderDto
 2 {
 3     public Guid Id { get; set; }
 4     public string CustomerName { get; set; }
 5     public List<OrderItemDto> Items { get; set; }
 6     public decimal TotalAmount { get; set; }
 7     public bool IsCancelled { get; set; }
 8 }
 9 
10 public class OrderItemDto
11 {
12     public Guid Id { get; set; }
13     public string ProductName { get; set; }
14     public decimal UnitPrice { get; set; }
15     public int Quantity { get; set; }
16 }
17 
18 public class InventoryDto
19 {
20     public Guid Id { get; set; }
21     public string ProductName { get; set; }
22     public int QuantityAvailable { get; set; }
23 }
View Code

 

 

11. 异常处理和库存操作优化

修改库存服务,增加对库存操作的详细异常处理,并优化库存数量的检查逻辑。

 

 1 public class InventoryService : DomainService
 2 {
 3     private readonly IRepository<Inventory, Guid> _inventoryRepository;
 4 
 5     public InventoryService(IRepository<Inventory, Guid> inventoryRepository)
 6     {
 7         _inventoryRepository = inventoryRepository;
 8     }
 9 
10     public async Task ReduceStockAsync(Guid inventoryId, int quantity)
11     {
12         var inventory = await _inventoryRepository.FindAsync(inventoryId);
13         if (inventory == null)
14             throw new EntityNotFoundException(typeof(Inventory), inventoryId);
15 
16         if (inventory.QuantityAvailable < quantity)
17             throw new BusinessException("Inventory insufficient.");
18 
19         inventory.ReduceStock(quantity);
20         await _inventoryRepository.UpdateAsync(inventory);
21     }
22 
23     public async Task IncreaseStockAsync(Guid inventoryId, int quantity)
24     {
25         var inventory = await _inventoryRepository.FindAsync(inventoryId);
26         if (inventory == null)
27             throw new EntityNotFoundException(typeof(Inventory), inventoryId);
28 
29         inventory.IncreaseStock(quantity);
30         await _inventoryRepository.UpdateAsync(inventory);
31     }
32 }
View Code

 

 

12. 添加订单修改功能

允许用户修改订单项,例如增加或减少商品数量。

 1 public class SalesOrder : AuditedAggregateRoot<Guid>
 2 {
 3     // Existing properties and methods
 4 
 5     public void UpdateItem(Guid itemId, int newQuantity)
 6     {
 7         var item = Items.Find(i => i.Id == itemId);
 8         if (item == null)
 9             throw new BusinessException("Item not found in order.");
10 
11         TotalAmount += (newQuantity - item.Quantity) * item.UnitPrice;
12         item.UpdateQuantity(newQuantity);
13     }
14 }
15 
16 public class OrderItem : Entity<Guid>
17 {
18     // Existing properties and methods
19 
20     public void UpdateQuantity(int newQuantity)
21     {
22         if (newQuantity <= 0)
23             throw new BusinessException("Quantity must be positive.");
24 
25         Quantity = newQuantity;
26     }
27 }
View Code

 

 

13. 扩展应用服务以支持订单修改

修改 SalesOrderAppService 以支持订单项的更新操作。

 1 public class SalesOrderAppService : ApplicationService
 2 {
 3     // Existing properties and methods
 4 
 5     public async Task UpdateOrderItemAsync(Guid orderId, Guid itemId, int newQuantity)
 6     {
 7         var order = await _salesOrderRepository.GetAsync(orderId);
 8         order.UpdateItem(itemId, newQuantity);
 9         await _salesOrderRepository.UpdateAsync(order);
10     }
11 }
View Code

 

14. 订单修改事件处理

如果需要,可以添加事件处理来响应订单修改,比如日志记录或其他业务规则。

 1 public class OrderItemUpdatedEvent : DistributedEntityEventData<OrderItem>
 2 {
 3     public int NewQuantity { get; }
 4 
 5     public OrderItemUpdatedEvent(OrderItem entity, int newQuantity) : base(entity)
 6     {
 7         NewQuantity = newQuantity;
 8     }
 9 }
10 
11 public class OrderItemUpdatedEventHandler : ILocalEventHandler<OrderItemUpdatedEvent>, ITransientDependency
12 {
13     public async Task HandleEventAsync(OrderItemUpdatedEvent eventData)
14     {
15         Logger.Info($"Order item {eventData.Entity.Id} updated to quantity {eventData.NewQuantity}.");
16         // Additional business logic can be implemented here
17     }
18 }
View Code

 

15. 自动库存补充策略

首先,我们实现一个服务来自动检测库存低阈值,并触发库存补充。

 1 public class AutoRestockService : DomainService
 2 {
 3     private readonly IRepository<Inventory, Guid> _inventoryRepository;
 4 
 5     public AutoRestockService(IRepository<Inventory, Guid> inventoryRepository)
 6     {
 7         _inventoryRepository = inventoryRepository;
 8     }
 9 
10     public async Task CheckAndRestockAsync()
11     {
12         var inventories = await _inventoryRepository.GetListAsync();
13         foreach (var inventory in inventories)
14         {
15             if (inventory.QuantityAvailable < 10) // Assume restock threshold is 10
16             {
17                 // Logic to restock automatically or send notifications
18                 inventory.IncreaseStock(20); // Assume fixed restock quantity
19                 await _inventoryRepository.UpdateAsync(inventory);
20                 await CurrentUnitOfWork.SaveChangesAsync();
21             }
22         }
23     }
24 }
View Code

 

16. 多种库存状态更新

扩展库存服务,添加多种库存更新策略,如临时锁定库存和释放锁定库存。

 1 public class InventoryService : DomainService
 2 {
 3     // Existing methods
 4 
 5     public async Task LockStockAsync(Guid inventoryId, int quantity)
 6     {
 7         var inventory = await _inventoryRepository.GetAsync(inventoryId);
 8         if (inventory.QuantityAvailable < quantity)
 9             throw new BusinessException("Not enough inventory to lock.");
10 
11         inventory.ReduceStock(quantity); // Temporarily lock stock
12         await _inventoryRepository.UpdateAsync(inventory);
13     }
14 
15     public async Task UnlockStockAsync(Guid inventoryId, int quantity)
16     {
17         var inventory = await _inventoryRepository.GetAsync(inventoryId);
18         inventory.IncreaseStock(quantity); // Release locked stock
19         await _inventoryRepository.UpdateAsync(inventory);
20     }
21 }
View Code

 

17. 异常监控与记录

加强系统的异常处理机制,记录关键操作和异常情况。

 1 public class ErrorHandlingDecorator : IApplicationService
 2 {
 3     private readonly IApplicationService _innerService;
 4 
 5     public ErrorHandlingDecorator(IApplicationService innerService)
 6     {
 7         _innerService = innerService;
 8     }
 9 
10     public async Task InvokeAsync(Func<Task> action)
11     {
12         try
13         {
14             await action();
15         }
16         catch (BusinessException ex)
17         {
18             Logger.Warn($"Business exception occurred: {ex.Message}");
19             throw;
20         }
21         catch (Exception ex)
22         {
23             Logger.Error($"Unexpected exception occurred: {ex.Message}", ex);
24             throw new GeneralApplicationException("An error occurred, please contact support.", ex);
25         }
26     }
27 }
View Code

 

18. 扩展查询服务

为了支持复杂查询,如获取库存的详细历史记录或订单的完整生命周期信息,我们可以增加更多的查询功能。

 1 public class QueryService : ApplicationService
 2 {
 3     // Existing methods
 4 
 5     public async Task<List<InventoryHistoryDto>> GetInventoryHistoryAsync(Guid inventoryId)
 6     {
 7         var inventory = await _inventoryRepository.GetAsync(inventoryId);
 8         return ObjectMapper.Map<List<InventoryHistory>, List<InventoryHistoryDto>>(inventory.History);
 9     }
10 
11     public async Task<List<OrderLifecycleDto>> GetOrderLifecycleAsync(Guid orderId)
12     {
13         var order = await _salesOrderRepository.GetAsync(orderId);
14         return ObjectMapper.Map<List<OrderEvent>, List<OrderLifecycleDto>>(order.Events);
15     }
16 }
View Code

 

19. 库存预警通知

我们将实现一个库存预警系统,该系统会在库存达到一定阈值时通知管理员或相关人员,这有助于及时补货。

 1 public class InventoryAlertService : DomainService
 2 {
 3     private readonly IRepository<Inventory, Guid> _inventoryRepository;
 4     private readonly INotificationService _notificationService;
 5 
 6     public InventoryAlertService(IRepository<Inventory, Guid> inventoryRepository, INotificationService notificationService)
 7     {
 8         _inventoryRepository = inventoryRepository;
 9         _notificationService = notificationService;
10     }
11 
12     public async Task CheckInventoryLevelsAsync()
13     {
14         var inventories = await _inventoryRepository.GetListAsync();
15         foreach (var inventory in inventories)
16         {
17             if (inventory.QuantityAvailable < inventory.AlertThreshold)
18             {
19                 await _notificationService.NotifyAsync($"Low stock alert for {inventory.ProductName}: only {inventory.QuantityAvailable} left.");
20             }
21         }
22     }
23 }
View Code

 

20. 增加性能监控和优化

引入性能监控功能,通过记录关键操作的执行时间来帮助识别性能瓶颈。

 1 public class PerformanceMonitoringDecorator : IApplicationService
 2 {
 3     private readonly IApplicationService _innerService;
 4 
 5     public PerformanceMonitoringDecorator(IApplicationService innerService)
 6     {
 7         _innerService = innerService;
 8     }
 9 
10     public async Task<T> ExecuteAsync<T>(Func<Task<T>> func)
11     {
12         var stopwatch = Stopwatch.StartNew();
13         try
14         {
15             return await func();
16         }
17         finally
18         {
19             stopwatch.Stop();
20             Logger.Info($"Operation executed in {stopwatch.ElapsedMilliseconds} ms.");
21         }
22     }
23 }
View Code

 

 

21. 订单历史追踪功能

实现订单历史记录功能,允许系统跟踪订单的每次更改,包括状态更新、订单项修改等

 1 public class OrderHistoryService : DomainService
 2 {
 3     private readonly IRepository<SalesOrder, Guid> _salesOrderRepository;

11 
12     [UnitOfWork]
13     public async Task CancelOrderAndUpdateInventoryAsync(Guid orderId)
14     {
15         var order = await _salesOrderRepository.GetAsync(orderId);
16         order.CancelOrder();
17         foreach (var item in order.Items)
18         {
19             await _inventoryService.IncreaseStockAsync(Guid.NewGuid(), item.Quantity); // Assuming a method to get the corresponding inventory
20         }
21         await _salesOrderRepository.UpdateAsync(order);
22     }
23 }

 8         _salesOrderRepository = salesOrderRepository;
 9         _permissionChecker = permissionChecker;
10     }
11 
12     public async Task CancelOrderAsync(Guid orderId)
13     {
14         if (!await _permissionChecker.IsGrantedAsync("OrderManagement.Cancel"))
15         {
16             throw new BusinessException("You do not have permission to cancel orders.");
17         }
18 
19         var order = await _salesOrderRepository.GetAsync(orderId);

 9 
10     public async Task ApproveOrderAsync(Guid orderId)
11     {
12         var order = await _salesOrderRepository.GetAsync(orderId);
13         if (order.Status != OrderStatus.PendingApproval)
14         {
15             throw new BusinessException("Order is not in a state that can be approved.");
16         }
17 
18         order.Status = OrderStatus.Approved;
19         await _salesOrderRepository.UpdateAsync(order);
20     }
21 
22     public async Task RejectOrderAsync(Guid orderId)
23     {
24         var order = await _salesOrderRepository.GetAsync(orderId);
25         if (order.Status != OrderStatus.PendingApproval)
26         {
27             throw new BusinessException("Order is not in a state that can be rejected.");
28         }
29 
30         order.Status = OrderStatus.Rejected;
31         await _salesOrderRepository.UpdateAsync(order);
32     }
33 }
34 
35 public class SalesOrder : AuditedAggregateRoot<Guid>
36 {
37     public OrderStatus Status { get; set; }
38     // Existing properties and methods
39 }
40 
41 public enum OrderStatus
