PPP模式下基于MVC的公共服务互动平台设计

Design of public service interaction platform based on MVC in PPP mode

为了提升公共服务质量与公众满意度,设计PPP模式下基于MVC的公共服务互动平台。基于MVC模式的模型、视图与控制器三部分原理,结合J2EE体系内各项技术设计公共服务互动平台,通过平台客户层中Web浏览器提供用户需求,由表示层中控制器接收需求后,调用业务层中会话bean逻辑处理对应需求业务,引入聊天室技术和隐藏帧刷技术解决处理页面闪烁问题,将处理后数据存入数据层的数据库中,通过MVC资源选取数学模型内置多目标遗传算法选取数据库内有效数据资源,并调度到业务层中,经实体bean处理后返回数据到表示层,向用户呈现处理的结果,并通过Web浏览器向用户提供相应服务。结果表明,该平台具有较高的资源调度效率与资源利用率,运行性能稳定,抗压能力强,设计合理且用户满意度高,实际应用性较高。

A public service interaction platform based on MVC(model view controller)in PPP(public private partnership)mode is designed to improve the quality of public service and public satisfaction.On the basis of the three principles of the model,view and controller in MVC mode,the public service interactive platform is designed in combination with various technologies in the J2EE system,and the Web browser in the platform client layer is used to provide the user requirement.After receiving the requirement from the controller in the presentation layer,the session Bean logic on the business layer is invoked to process the corresponding demand business,and the chat room technology and hidden frame brush technology are introduced to solve the problem of page flicker during processing.The processed data is stored in the database of the data layer.The built⁃in multi⁃objective genetic algorithm of the MVC resource selection mathematical model is used to select the effective data resources in the database and schedule them to the business layer.The data is sent back to the presentation layer after it is processed by entity Bean to present the processed results to users and provide corresponding services for users on Web browser.The results show that the platform has high efficiency of resource scheduling,high resource utilization,stable operation performance,strong compression resistance,reasonable design,high user satisfaction,and high practical applicability.
