They are made up of several classes, each performing a specific purpose within the application. These applications are like any Java application. 15) What does a simple spring application contain? This file contains the classes information and describes how these classes are configured and introduced to each other. Spring configuration file is an XML file. 13) What is AOP Alliance?ĪOP Alliance is an open-source project whose goal is to promote adoption of AOP and interoperability among different AOP implementations by defining a common set of interfaces and components. 12) What is a BeanFactory?Ī BeanFactory is an implementation of the factory pattern that applies Inversion of Control to separate the application’s configuration and dependencies from the actual application code. It also can take advantage of any of Spring’s other services, such as I18N messaging and validation. It also allows you to decoratively bind request parameters to your business objects. Although Spring can easily be integrated with other MVC frameworks, such as Struts, Spring’s MVC framework uses IoC to provide for a clean separation of controller logic from business objects. Spring comes with a full-featured MVC framework for building web applications. It also contains integration support with Jakarta Struts. This module also contains support for several web-oriented tasks such as transparently handling multipart requests for file uploads and programmatic binding of request parameters to your business objects. This module is built on the application context module, providing a context that is appropriate for web-based applications. Spring’s transaction management supports each of these ORM frameworks as well as JDBC. Spring provide support to tie into several popular ORM frameworks, including. Spring also supports for using of an object/relational mapping (ORM) tool over straight JDBC by providing the ORM module. 9) What are object/relational mapping integration module? In addition, this module uses Spring’s AOP module to provide transaction management services for objects in a Spring application. A new layer of meaningful exceptions on top of the error messages given by several database servers is bought in this module.

Using this module we can keep up the database code clean and simple, and prevent problems that result from a failure to close database resources. 8)What is JDBC abstraction and DAO module?

Using Spring’s metadata support, we will be able to add annotations to our source code that instruct Spring on where and how to apply aspects. This module also introduces metadata programming to Spring.

Much of the support has been provided by the AOP Alliance in order to ensure the interoperability between Spring and other AOP frameworks. The AOP module is used for developing aspects for our Spring-enabled application. It also provides support to other framework. This module also supplies many enterprise services such JNDI access, EJB integration, remoting, and scheduling. This module extends the concept of BeanFactory, providing support for internationalization (I18N) messages, application lifecycle events, and validation. The Application context module makes spring a framework. The entire framework was built on the top of this module. In this module BeanFactory is the heart of any spring-based application. This module is provides the fundamental functionality of the spring framework.

O/R mapping integration module (Object/Relational)Ĥ) What is the structure of Spring framework?.

AOP module (Aspect Oriented Programming).

Framework : Spring provides most of the intra functionality leaving rest of the coding to the developer.ģ) What are the different modules in Spring framework?.

Container : Spring contains and manages the life cycle and configuration of application objects.Aspect oriented (AOP) : Spring supports Aspect oriented programming and enables cohesive development by separating application business logic from system services.The objects give their dependencies instead of creating or looking for dependent objects. Inversion of control (IoC) : Loose coupling is achieved in spring using the technique Inversion of Control.And the processing overhead is also very negligible. The basic version of spring framework is around 1MB. Lightweight : Spring is lightweight when it comes to size and transparency.
