摘要:
随着信息化技术的快速发展,企业所积累的信息资源持续增长,各企业都在各自的业务支撑领域建立了各式各样的信息系统。人们急需将这些不同部门不同功能的软件系统集成起来,实现信息共享。文中对实现共享服务的方法进行了研究,通过实现一个组装流程将获取不同应用系统中数据的各种方法组装成服务,以实现系统之间数据的交互。基于 HTML5 新特性 Canvas,实现了在浏览器中通过拖动组件的方式组装服务流程,无需安装任何插件,采用异步刷新的方式完成对浏览器的更新。 利用直接调用和基于消息方式的调用两种方法,实现了对不同服务接口的统一调用,并利用超级代理的方式对各个组件实现统一调用,有效地降低了逻辑与事务处理之间的耦合度,成功解决了不同服务需要调用不同服务器上的不同组件方法,实现系统之间的数据共享。
Abstract:
With the rapid development of information technology,the accumulated information resources of enterprises continue to grow,and various enterprise have established various information systems in their business support fields. There is an urgent need to integrate these software systems with different functions of different departments for information sharing. Therefore,the method of implementing shared services is studied. By implementing an assembly process,various methods for acquiring data in different application systems are assembled into services to realize data interaction between systems. Based on the new feature of HTML5,Canvas,the assembly process into a service flow by dragging components in the browser without installing any plug-ins is realized,and the browser in an asynchronous manner is updated. The unified invocation of different service interfaces is realized by using direct invocation and message-based invocation. The super-agent is used to implement unified calling for each component, which effectively reduces the degree of coupling between logic and transaction processing and successfully solves the problem that different services need to call different component methods on different servers. Finally,data sharing between systems is realized.
