基于领域消息驱动的轻量级Spring-DDD插件设计与实现

摘要

DDD (domain driven development) is entirely memory⁃based business object modeling (In⁃Memory) method, but the current DDD framework is not stable enough to cover the system business completely and can not be applied to the de⁃velopment of practical project. On the basis of Spring framework,the DDD plug⁃in based on domain message driving and memo⁃ry modeling was realized,in which the implementation of the project is fully compatible with DDD design without affecting the current system architecture. The domain event message and domain object caching model based on JDK and Disruptor concurren⁃cy control framework can effectively reduce the decoupling relationship and improve the whole performance and efficiency of the system.%领域驱动开发（DDD）是完全基于内存的业务对象建模（In⁃Memory）方法，而目前的DDD框架不能完全覆盖系统业务，也不成熟稳定，无法应用于实际项目的开发。在Spring框架的基础上，实现了一个基于领域消息驱动和内存建模的DDD插件，在不影响目前系统架构的基础上，让项目实施完全兼容DDD设计。同时基于JDK和Disruptor并发框架实现的领域事件消息和领域对象缓存模型，有效地降低了系统的解耦关系，并提高了系统的整体性能及效率。
