Practice of J2EE Design Patterns in a Common Library Automation Management System
Reasonable using of all sorts of relevant design pattern is an important guarantee of high quality design of application system. To solve the problem of absence of business service ability existing in current academic libraries management systems based on web that is not suitable for the joint construction and sharing of information resources,a J2EE-based solution is introduced. The J2EE fourlayer architecture and software frame based on MVC model 2 are given. On the design of concrete pattern,Application Controller is designed in the Presentation layer,Session Facade and Service Locator are used in the Business Logic layer. And Value Object is adopted in Data Persistence layer. BeanManaged Persistent as Model is emphasized. The development of patterns is illustrated through implementation process of layers. The integrated application of design patterns simplifies overall design and improves the system performance. The system also provides a new attempt for network realization of academic libraries.
