The Test Library Management System of
Framework Based on SSH
The application system features in small or medium—sized enterprise lie in the g
reater flexibility and safety high performance—price ratio. Traditional J2EE framewor
k can not adapt to these needs, but the system application based on SSH
(Struts+Spring+Hibernate) technology can better satisfy such needs。 This paper an
alyses some integration theory and key technologies about SSH, and according to th
e integration constructs a lightweight WEB framework , which has integrated the thr
ee kinds of technology
,
forming the lightweight WEB framework based on SSH and gaining good effects in p
ractical applications。
Introduction
Generally the J2EE platform
[27] used in large enterprise applications, can well solve the application of reliab
ility, safety and stability, but its weakness is the price high and the constructing cycl
e is long. Corresponding to the small or medium enterprise applications, the replace a
pproach is the system framework of lightweight WEB, including the more commonly
used methods which are based on the Struts and Hibernate. With the wide application
of Spring, the three technology combination may be a better choice as a lightweight
WEB framework. It uses layered structure and provides a good integrated framework
for Web applications at all levels in minimizing the Interlayer coupling and increasing
the efficiency of development。 This framework can solve a lot of problems, with
good maintainability and scalability. It can solve the separation of user interface and b
usiness logic separation, the separation of business logic and database operation and
the correct procedure control logic, etc。 This paper studies the technology and pri
nciple of Struts and Spring and Hibernate, presenting a proved lightweight WEB appli
cation framework for enterprise。

y independent and mutual, and each module can be implemented according to differ
ent design. It can realize the system parallel development, rapid integration, good mai
ntainability, scalability.
Struts MVC Framework
To ensure the reuse and efficiency of development process, adopting J2EE techn
ology to build the Web application must select a system framework which has a good
performance 。 Only in this way can we ensure not wasting lots of time because of ad
justing configuration and achieve application development efficiently and quickly。 S
o, programmers in the course of practice got some successful development pattern wh
ich proved practical, such as MVC and O/R mapping, etc; many technologies, incl
uding Struts and Hibernate frameworks, realized these pattern. However, Struts frame
work only settled the separation problem between view layer and business logic layer
, control layer, did not provide a flexible support for complex data saving process。
On the contrary, Hibernate framework offered the powerful and flexible support for
complex data saving process。 Therefore, how to integrate two frameworks and get
a flexible, low—coupling solutions project which is easy to maintain for information s
ystem, is a research task which the engineering staff is studying constantly。
Model—View-Controller (MVC) is a popular design pattern。 It divides the int
eractive system in three components and each of them specializes in one task. The mo
del contains the application data and manages the core functionality。 The visual disp
lay of the model and the feedback to the users are managed by the view. The controlle
r not only interprets the inputs from the user, but also dominates the model and the v
iew to change appropriately. MVC separates the system functionality from the system
interface so as to enhance the system scalability and maintainability. Struts is a typi
cal MVC frame
[32], and it also contains the three aforementioned components。 The model level
is composed of JavaBean and EJB components. The controller is realized by action an
