2 Spring Framework
Spring Overview
Spring is an open source framework that you can use to develop enterprise applications. Its features
and functions are packaged in different modules. It includes a lightweight container that provides
a centralized, automated configuration and wiring of your application objects.
NOTE: Throughout this document, Spring refers to Spring version 3.1.0.
Spring includes the following:
•
A flexible MVC web application framework, built on core Spring functionality. This framework
is highly configurable using strategy interfaces, and accommodates multiple view technologies,
such as JSF.
•
Integration with other frameworks, such as Hibernate, with lots of IoC convenience features,
addressing many typical Hibernate integration issues.
•
A JDBC abstraction layer that supports exception hierarchy, simplifies error handling, and
reduces the effort in generating code.
•
Support for application testability and scalability by allowing software components to be first
developed and tested in isolation, then scaled up for deployment in any environment.
The NonStop system provides a platform comprising the Java Virtual Machine (JVM) and a servlet
container ― NSJSP. On NonStop systems, Java applications (created using Spring libraries) can
be run/deployed as:
•
Standalone applications on the JVM
•
Web applications under NSJSP
Spring Projects
The Spring community maintains several projects such as Spring Web Flow, Spring framework,
Spring Web Services, and Spring Security. Among these projects, only the Spring framework and
the Spring Web Flow is presently certified for use on the NonStop platform.
Spring Framework
The Spring framework is a layered development platform for developing Java applications in
different environments. Because the framework provides abstraction layers and modules, you can
use the Spring modules selectively based on your requirement.
The basic Spring framework consists of:
•
Core Container
•
Data Access/Integration layer (For examples on the Data Access/Integration layer, see
“Integrating Frameworks” (page 222) .)
•
Web layer (For examples on the Web layer, see “Getting Started with Spring” (page 38) .)
•
AOP and Instrumentation module (For examples on the AOP and Instrumentation layer, see
“Integrating Spring with Transaction Management Facility (TMF)” (page 27) .
•
Test module
