It is a light-weight framework for the development of enterprise-ready applications. It provides very simple and rich facilities to integrate various frameworks, technologies, and services in the applications.
One of the main reason for using the Spring framework is to keep the code as simple as possible. It pushes the way to develop enterprise applications with loosely coupled simple java beans. This Spring tutorial explains a lot of major modules of the Spring Framework. The Spring Framework has been categorized into modules. All modules will not be used in an application, so every module is dependent on the type of application.
There are 20 modules organized in Spring Framework. A configuration model and a dependency injection mechanism belong to the core container located in the heart of the framework. Beyond that, there are different application architectures such as transactional data, messaging, persistence and web for the foundational support. Spring is an open-source framework developed by Spring Source, a division of VMware. Spring framework can be summarized in two ways.
In this Spring tutorial, I have explained the Spring framework as a container and as a framework. The BeanFactory is a sophisticated implementation of the factory pattern. There is no need for programmatic singletons and they also allow decoupling the specification and configuration of dependencies from the actual program logic. Context is another module which is built on the solid base by the Core and Beans. This module is a way to access the objects in a framework-style and is similar to a JNDI registry.
It has the features from the Bean modules and supports internationalization, resource-loading, event-propagation and the transparent creation. The Context module has a focal point which is known as the ApplicationContext. The most powerful expression language used for manipulation and querying an object graph at runtime is said to be in the Expression Language. It acts as an extension of the unified expression language in the JSP 2. This language helps in setting and getting property values, method invocation, and access of context in arrays, property assignment, logical and arithmetic operators and retrieval of objects.
Spring framework can be described as a lightweight container, as it does not involve installation, configuration, start and stop activities associated with a container. The Spring Container takes the classes in the application, creates objects, and manages the life cycle of those objects. Spring framework can be described as an Application Programming Interface API containing a large collection of the classes, methods, interfaces, annotations, XML tags that can be used in an application.
The API provides a variety of factory and facade classes that help you to use any framework or functionality very easily in your application. The Core package is the most fundamental part of the framework and provides the IoC and Dependency Injection features.
The basic concept here is the BeanFactory , which provides a sophisticated implementation of the factory pattern which removes the need for programmatic singletons and allows you to decouple the configuration and specification of dependencies from your actual program logic. A JDBC-abstraction layer is formed in the JDBC module which removes the need to do tedious parsing and coding of itself with database-vendor specific error codes.
The implementation of special interfaces in programmatic and declarative transaction management for classes is only found in the Transaction module of POJOs.
Aspect-Oriented Programming AOP is an approach which allows global properties to define method-interceptors and pointcuts in an executable program. The main aim of this programming paradigm is to increase modularity without modifying the code instead of modifying via point-cut specification.
It provides integration with AspectJ. The Instrumentation module has class support and a classloader implementation in certain application servers. It also includes programming methods and tools which support modularization of concerns of the source code.
The initialization of the IoC container can take place using servlet listeners. This MVC of the Spring framework has both web forms and model code with a clear separation. The support classes for integration with a class Struts web tier is only found in the Web-Struts module.
It balances the consistency of loading in ApplicationContexts and caching of them in Spring. Mock objects are created to test the code in isolation.
Spring 3. The Inversion of Control IoC is a general concept, and it can be expressed in many different ways and Dependency Injection is merely one concrete example of Inversion of Control. Here the dependency part translates into an association between two classes. For example, class X is dependent on class Y. All this means is that class Y will get injected into class X by the IoC.
Dependency injection promotes loose coupling. It paves the way for the removal of the usual factory and utility classes that we write in our applications. Look Following in this Spring Tutorial:. The IoC refers to the control of creating instances. The container has a responsibility to control for creating and constructing objects. The container creates objects and injects them into our applications. After it is ready, there are five basic steps to create and run the program:.
There is a class Employee and for this class, there is an ID like employee ID where the employee name is coming in the below code. We will save the address of the employee with other details.
