摘　　要：业务逻辑层(BLL)与数据访问层(DAL)是MVC的核心层,BLL与DAL的实现,使Web应用系统具有更好的低耦合度,高模块化程度,易维护,易扩展。通过对传统的BLL与DAL的模型结构的进一步研究,分析出传统BLL与DAL存在重复率高,利用率低的缺陷。因此提出在Web应用中基于JPA规范和泛型程序设计,采用Spring Data JPA的BLL与DAL层的Nosql模型。通过该模型应用和模型评估,发现该模型与传统的模型结构相比,代码量少,利用率高,提高了Web应用软件的开发效率。Business logic layer(BLL)and data access layer(DAL)are the core layer of MVC.The realization of BLL and DAL makes Web application system have better low coupling degree,high modularity,easy maintenance and easy expansion.Through the traditional BLL and DAL model structure of the further study,The traditional BLL and DAL have the disadvantages of high repetition rate and low utilization rate.Therefore,Proposed in the Web application based on JPA specification and generic programming,using Spring Data JPA BLL and DAL layer Nosql model.Through the application of the model and the evaluation of the model,it is found that the model has less code and high utilization rate than the traditional model structure,which improves the development efficiency of Web application software.
