| 中文摘要:为将传统状态设计模式中具体状态下需要执行的业务逻辑和保存状态改变的逻辑解耦合，提出了一种融合Spring Event事件机制和Spring Data JDBC为持久化技术的状态设计模式。首先按照领域驱动设计思想，将对象状态定义为值对象，以状态对象所属的实体为聚合根，通过Spring Data JDBC对聚合整体进行持久化。然后定义状态改变所产生的事件，在对应的监听器中进行状态改变所要执行的业务。最后在聚合对应的领域服务中通过状态上下文调用聚合对象引起状态变化的业务方法。以电商平台的订单操作为实例，详细阐述了具体实现过程。实践结果表明，所提出的状态模式提供了一种更加灵活的状态管理机制，确保了领域服务中业务逻辑的稳定性，具有一定的参考价值。 |

| A State Design Pattern Integrating Spring Event and Spring Data JDBC |

| Abstract:In order to decouple the business logic that needs to be executed in specific states and the logic that saves state changes in traditional state design patterns, a state design pattern that integrates Spring Event event mechanism and Spring Data JDBC as persistence technology is proposed.Firstly, following the domain driven design concept, the object state is defined as a value object, and the entity to which the state object belongs is used as the aggregation root. Spring Data JDBC is used to persist the entire aggregation. Then define the events generated by the state change and execute the business required for the state change in the corresponding listener. Finally, in the aggregated domain service, the business method that triggers state changes by calling the aggregated object through the state context.Finally, in the aggregated domain service, the business method that triggers state changes by calling the aggregated object through the state context. Taking the order operation of e-commerce platforms as an example, the specific implementation process is elaborated in detail. The practical results show that the proposed state mode provides a more flexible state management mechanism, ensuring the stability of business logic in domain services and has certain reference value. |
