接口 IApplicationService

public interface IApplicationService

应用层服务.

远离业务模型核心层.

应用层，负责组织业务场景，编排业务，隔离场景对领域层的差异；领域层，实现具体的业务逻辑、规则，为应用层提供无差别的服务能力.

如果没有应用层，会导致领域层与具体场景绑定，复用性大大降低.

Application logic contains the workflow steps required to fulfill a business use case.

The application services don’t do any work, but they understand who to talk to to complete the task.

Coordinating the retrieval of domain objects from a data store, delegating work to them, and then saving the updated state is the responsibility of the application service layer.
