Research And Application Of Java Lightweight Framework In Occupational Skill Testing Authority System

With the extensive applied of Internet and Web, more and more enterprises eagerly require to efficiently design own software applications based on Web. In recent years, owing to the many specialities of Java and all kinds of experience of enterprise software development, J2EE of Sun Microsystem corp. becomes one of the most preferred platforms of enterprise development. J2EE defines a set of complete standards for developing distributed, multi-layer enterprise softwares. But for the many middle-small-scale enterprise systems based on Web, J2EE has many deficiencies, such as the complexity of developing, deploying and testing, and bad compatibilities of J2EE servers.So, it's a long time that enterprises explore a replacement of J2EE. By analyzing traditional J2EE technology, this thesis provided a lightweight development solution—integrated Spring and Hibernate, which is especially suitable for the middle-small-scale enterprises and applied to WuGang Occupational Skill Testing Authority System. Strictly based on the consider of layered multi-layer architecture, the solution maked use of Spring MVC, JSTL and Spring lable in presentation layer, adopts Spring IoC in business layer and last in persistent layer uses most popular Java O/R Mapping tool Hibernate.Making use of integrated lightweight framework to develop enterprise application based on Web, it can avoid traditional J2EE complexity and build efficient and correspond software, it can also separates function of business logic, system control logic from data render that are mostly concerned by programmer. And at last the system developed with it has characteres of loose coupling, high reuseable, good explanation and extension and so on. Through running, it proves that the function of WuGang Occupational Skill Testing Authority System has reached design requirements by making use of the solution.Firstly, by compareing traditional J2EE technology with lightweight framework, this thesis drew a conclusion that lightweight framework has characteristics of developed fastly, configured simple, and easy to use. Then the thesis thoroughly introduced open frameworks of Spring and Hibernate. At last it implemented the authority management module of WuGang Occupational Skill Testing Authority System, based on Spring and Hibernate.
