摘　　要：为使批量上传并解析PDF技术具备较高的扩展性和易用性，本文主张使用Adapt和Strategy等设计模式降低第三方组件、特征字符等变化点对源程序本身的影响，甚至使用Factory设计模式和Reflect技术将依赖关系转移至配置文件，使得只需修改配置文件就可应对未来变化。此外，还将异步环境分隔成异步上传和同步数据库操作两段，通过Kequest传入值和Session传出值实现异步与同步的通信，从而提高性能。In order to batch upload and parse the PDF with high salability and usability, the paper advocates the use of the design pattern, such as Adapt and Strategy etc, to reduce the influence of the third-party components and characteristic characters change point to the source program itself, even to use the Factory design pattern and Reflect technology to transfer dependency to configuration files, so that just to modify the configuration files can cope with the change in the future. In addition, it divides the uploading asynchronous environment into asynchronous and synchronous database operations, and improves the performance by the incoming value of Request and out value of Session.
