ABP.IO - Handle multiple events in same microservice
问题
根据以下文档和示例来处理不同事件，我需要拥有3个微服务来处理资源的创建、更新和删除吗？还是我需要编写类似以下的代码？
namespace AbpDemo{public class MyHandler: IDistributedEventHandler<EmployeeServiceEto>,ITransientDependency{public async Task HandleEventAsync(EmployeeServiceEto eventData){if (eventData.EventType = EventType.Created)// 调用创建员工的方法if (eventData.EventType = EventType.Updated)// 调用更新员工的方法if (eventData.EventType = EventType.GetAll)// 调用获取所有员工的方法}}}
有人可以帮我提供使用 abp.io 框架在同一个微服务中处理多个事件的示例吗？
英文:
Considering the below documentation and the example to handle different events
https://docs.abp.io/en/abp/latest/Distributed-Event-Bus#pre-defined-events
Do I need to have 3 microservices to handle create, update & Delete for a resource?
or Do I need to write something like this?
namespace AbpDemo{public class MyHandler: IDistributedEventHandler<EmployeeServiceEto>,ITransientDependency{public async Task HandleEventAsync(EmployeeServiceEto eventData){if(eventData.EventType = EventType.Created;// call Create Employee Methodif(eventData.EventType = EventType.Updated;// call Update Employee Methodif(eventData.EventType = EventType.GetAll;// call GetAllEmployees}}}
Can someone help me with an example of handling multiple events in the same microservice using apb.io framework?

ABP Framework提供了三种预定义的事件类型，例如EntityCreatedEto<T>、EntityUpdatedEto<T>和EntityDeletedEto<T>。您可以使用这些类型来订阅创建、更新和删除事件。
您可以查看以下示例：
namespace AbpDemo{public class MyHandler :IDistributedEventHandler<EntityCreatedEto<EmployeeServiceEto>>,IDistributedEventHandler<EntityUpdatedEto<EmployeeServiceEto>>,IDistributedEventHandler<EntityDeletedEto<EmployeeServiceEto>>,ITransientDependency{public virtual async Task HandleEventAsync(EntityCreatedEto<EmployeeServiceEto> eventData){//当新实体创建时的逻辑}public virtual async Task HandleEventAsync(EntityUpdatedEto<EmployeeServiceEto> eventData){//当实体更新时的逻辑}public virtual async Task HandleEventAsync(EntityDeletedEto<EmployeeServiceEto> eventData){//当实体删除时的逻辑}}}
如果您像这样操作，那么您就不需要检查EventType。ABP框架的示例可以在这里查看。
英文:
ABP Framework provides three pre-defined event types such as EntityCreatedEto<T>, EntityUpdatedEto<T>, and EntityDeletedEto<T>. You can use these types to subscribe for create, update, and delete events.
You can see the following example:
namespace AbpDemo{public class MyHandler :IDistributedEventHandler<EntityCreatedEto<EmployeeServiceEto>>,IDistributedEventHandler<EntityUpdatedEto<EmployeeServiceEto>>,IDistributedEventHandler<EntityDeletedEto<EmployeeServiceEto>>,ITransientDependency{public virtual async Task HandleEventAsync(EntityCreatedEto<EmployeeServiceEto> eventData){//your logic for when a new entity created}public virtual async Task HandleEventAsync(EntityUpdatedEto<EmployeeServiceEto> eventData){//your logic for when the entity updated}public virtual async Task HandleEventAsync(EntityDeletedEto<EmployeeServiceEto> eventData){//your logic for when the entity deleted}}}
If you do it like that, then you don't need to check the EventType. An example from the ABP Framework can be seen here.
