Estudo de caso usando o Spring Framework para a criação de aplicações web com J2EE

Abstract

This paper presents a case study about Framework Spring used in the construction of applications to distributed environments or enterprise. Through this study, we searched to stick out the simplification importance of the applications development process based in the Java 2 Enterprise Edition (J2EE) specification. Therefore was necessary to introduce some concepts, as Design Patterns, which the developers would use in the multi-layers architecture creation (n-tier) to solve specific problems found in corporative environments. Nowadays, there are uncountable frameworks solutions liable to utilization in web applications; however, the configuration process of these solutions to team-work is still too expensive. Hence, one of the greatest Framework Spring contributions is the transparent configuration of technological solutions chosen to use by application, releasing the developers to the exclusive focus in questions related with the business or end area of company or organization. The paper is separated in three main chapters respectively about: literature revision (Framework Spring, Definitions; the Enterprise development process; Aspects; Elements); case study (Appfuse and Equinox projects presentation as framework Spring effective utilization example); of contributions; and author considerations about approached topics.
