Following are the benefits offered by the Spring Framework.
• It is possible to develop enterprise level application in Spring using POJOS. The major benefit of using POJO is that you can avoid EJB container like application server. In such cases you just need to use a web server like Tomcat or any other commercial product.
• A modular style is used to organize Spring. There are lot of packages and classes but you must only consider the classes being used by you.
• The spring
For Java enterprise application development the most popular development framework is Spring. The Spring framework is being used by the million of developers around the work. It is possible to create easily testable, high performing and reusable code.
The Spring is an open source Java platform based Framewrok. The Spring framework was first released in June 2003 under the Apache 2.0 license and it was written by Rod Johnson initially.
When considering the transparency
The Spring framework has great support for Log4J and it is easy to use Log4J for logging inside Spring applications. In this section, we will discuss the Log4J and Spring integration and how you can use it.
To install the Log4J on you machine, download it from the apache website, extract the zip file and use the log4j.jar in your project.
The Jakarta commons loggin (JCL) API provides an alternative approach to support loggin in your Spring application. Jakarta commons loggin API can
The DispatcherServlet provides the base for Spring web model view controller framework. The DispatcherServlet handles all the HTTP responses and requests. The below diagram explains the request processing workflow based on the Spring Web MVC DispatcherServlet. Spring Servlet Dispatcher
For an incoming HTTP request, following sequence of events are generated.
• The HandlerMapping is consulted to call the related Controller when
The model view controller architecture is provided by the Spring Web MVC framework and it also provides ready components which are used to generate loosely coupled and flexible web applications. The different application aspects are separated in result of MVC pattern like business logic, input logic and UI logic. This pattern will provide loose coupling between the elements.
• The model data is encapsulated by the Model and it is consist of POJO in general.
• The model data
Spring is considered as a widely deployed and popular deployed “open source” framework which assists programmers to create higher quality applications quickly. A consistent configuration model and programming is provided by Spring which is understood very well and is used by developers globally. Range of capabilities are provided by Spring to create rich web, enterprise Jave and enterprise applications which could be utilized in a light weighted manner. Spring used for Enterprise
Few associated benefits of Spring that could be brought to some project are listed here: Your mid-tier objects could be organized effectively by Spring whether you use EJB or not. Plumbing is being taken care by Spring which would be there with you when only struts or some other framework is used particular to J2EE APIs. Most probably this is much more valuable for mid tier so configuration management services of spring could be utilized in any kind of architectural layer, no matter
Configuration model and comprehensive programming is provided by the spring framework for the moderanized java based application for any of the deployment platform. Spring key element is the infra-strutural support provided at the level of application: Spring keeps its focus at the enterprise application plumbing therefore teams could keep their focus at the business logic which is application level without any unessential ties with deployment environment.
