Study On The Healthy Information Integration Model Based On The Struts Architecture

The E-Business has been widely used in society. As the one of main development platform of the E-Business, J2EE (Java2EnterpriseEdition) technology is accepted by a lot of developers. The support of middleware and much framework are the main reasons of developers'choice. Dvelopers can choose the business J2EE application server for charge. For example, WebLogic and Websphere.They can also choose a free one.For examples, JBOSS used as EJB container and Tomcat as Servlet container. It is easy to satisfy the different needs. Framework is the shortcut for developers. And as a MVC framework, Struts is the best one of them. But struts has shortcoming. It has weak support in view and data layers, and there are too many partitions in control layer. Healthy information integration model is the application framework which implements MVC based on J2EE platform. It eases the burden of constructing mufti-layer Web applications and provides reusable software architecture. The e-healthy system improves the Struts framework to overcome the shortcomings of Struts. It concerns in analysis and design of the kennel layer. Not only including popular technology in each layer, but also including the recommendation of common class libraries (package), which will improve the efficiency of development process of E-Business. The e-healthy system is the project of Japan economic department, which is used to collection and display the information of user's health status on the network. Here will take this system as the example to show important aspects of java Web development: usage of the Frame (Struts), configuration of the application server (WebLogic and Tomcat), database access, log and chart component. These are all the most general function modules for Web development. With the general design, developer can realize different system by only changing config files instead of changing the source code. More than 80 percent of source code of general module can be reused without change, because the design of general module is independent with the practical business needs. By the use of Struts framework and general module, developer will only be concerned in the realization of business needs in the development process. This will greatly improve the develping efficiency deeply.
