【摘要】：由于企业软件体系和当代信息发展相对不同步的问题日渐凸显,寻找一种灵活的,可以满足不同业务需求、对接多样业务接口、跨越不同技术平台的软件结构解决方案成为当下软件架构体系的当务之急。而服务(service),作为一个封闭的元功能函数模块,越来越多的出现在企业应用构建体系中,面向服务的软件体系架构(Service Oriented Architecture,SOA)由于具有松耦合、重用性、跨平台等优势,被再次提及并不断发展壮大,成为继面向对象、面向组件之后的新一代软件体系架构解决方案。使用面向服务的建模与体系结构的分析方法(Service Oriented Modeling and Architecture,SOMA),可以将现有的企业应用软件进行新的编排和重组,并轻松地添加新的服务以满足不断发展的企业需求,最大限度的减少了技术人员的工作量,提高了现有的代码重用率,同时增加了系统灵活性,提高了系统的响应效率,实现了整体意义上的系统重构。本文研究了面向服务的Web报表设计器,通过提供服务的方式保障系统功能需求。设计器作为一个粗粒度的服务,由多个细粒度的子服务构成,通过转换接口的方式为不同业务系统提供模板设计服务。在布局方式上,采用基于ESB中间件的方式部署服务,为服务提供了便捷的消息传递和服务管理。在设计实现上,使用拖拽控件的方式,选择式配置数据库,降低开发难度,便于使用和维护。用XML格式保存和设计模板文件,改变映射规则即可快捷地转化模板文件的格式以便导出。解决了当下面向对象、面向集成、面向组件等紧耦合架构模式下报表设计器灵活性差、重用性低的问题,具有易用、交互、并发、可扩展等特点。
[Abstract]:Because the enterprise software system and the contemporary information development are relatively out of step with each other, we are looking for a flexible one that can meet different business needs and connect with various business interfaces. The solution of software architecture across different technology platforms becomes the urgent task of the current software architecture system. As a closed meta-functional function module, Service-Oriented Service Oriented Architecture (SOA) is becoming more and more popular in enterprise application building system, because of its advantages of loose coupling, reusability, cross-platform and so on. It has been mentioned again and has become a new generation of software architecture solution after object-oriented and component-oriented. Using a service-oriented modeling and architecture analysis approach, Service Oriented Modeling and Architecture can be used to orchestrate and reorganize existing enterprise applications and easily add new services to meet evolving enterprise needs. It reduces the workload of technicians, improves the reuse rate of existing code, increases the flexibility of the system, improves the response efficiency of the system, and realizes the system reconfiguration in the whole sense. In this paper, the service-oriented Web report designer is studied to ensure the functional requirements of the system by providing services. As a coarse-grained service, the designer consists of several fine-grained sub-services, which provide template design services for different business systems by transforming interfaces. In the layout mode, the service is deployed based on ESB middleware, which provides convenient message passing and service management for the service. In the design and implementation, the method of drag-and-drop control is used to select the configuration database, which can reduce the development difficulty and be easy to use and maintain. Using XML format to save and design template files, changing the mapping rules can quickly transform the format of template files for export. It solves the problem of poor flexibility and low reusability of report designer in tight coupling architecture such as object-oriented, integration-oriented and component-oriented, and has the characteristics of easy to use, interactive, concurrent, extensible and so on.
