MVC is the trendy web development framework pushed by Microsoft, that the ecommerce Development Company or Magento Development masters can better assist us in the development of a project.
2. What is Spring MVC ?
Spring is today one of the most prominent Java frameworks. Based on simple concepts, it nevertheless makes it possible to considerably modify the traditional development processes of Java projects.
Rod Johnson, its creator, was one of the first to rise up against certain standards included in the Java EE platform, lambasting a complexity of development too big for his taste. He was an early supporter of a development model based on the good old POJO (Plain Old Java Object).
The evolution of the Java development platform gave him to reason; a redesign of programming models of EJB3 is a perfect example. Nevertheless, Spring breakthrough found on current projects can be puzzling as to the use that is made of it. If it is important and justified to recognize many qualities, it seems important to frame its use to avoid drifts related to overuse.
It may be necessary to look for the EJB3 which, although coming after Spring, are strongly inspired by it and have the interesting and indispensable advantage of being a standard!
3. Spring: Java for Modern Web Development
From the beginning, Java and related technologies were designed for Web development. After some launching difficulties due mainly to the low level of support of previous browsers, the still low bandwidths of private Internet connections and the still insufficient power of old PCs, the programming language did not break through until the end of the 1990s.
At the very beginning of the World Wide Web, Java applets were still popular (applications are written in Java that are run in the browser using the appropriate runtime environments and can interact with the user without having to send.
However, because of their significant resource requirements, they were not very practical. With the advent of mobile devices, which do not support applets, interactive Web elements have completely disappeared screen.
While Java has made a frontend flop quite quickly, the programming language has become considerable on the server side, which means that the application scenarios are very variable: servlets and applets run on the server to complex enterprise solutions such as Middleware, banking software or large content management systems, the different Java technologies are today more in demand than ever, if at least the budget allows. Given its cost and time advantages, nearly three-quarters of all websites use the PHP scripting language.
For web developers, who work with Java, however, Spring provides both the necessary structures and a significant simplification of the workflow. The advantages of Java web applications are, among others, their platform independence, and their ability to integrate with enterprise software and processes, and their clear structure.
4. For which projects is the Java framework best suited?
Spring is often described as a lightweight framework for Java applications since almost no source code changes are needed to take advantage of its many benefits. These include simplification in the implementation of transaction management, interfaces and access to databases.
The ability to easily perform unit and integration tests is also a reason why the Spring Framework is so popular.
The central point is definitely giving up on platform-specific and non-standard components, making Spring highly portable and independent of application servers. As a result, it is very easy to install as a meta-framework, in which other external components or even frameworks can be integrated.
A typical application example is the development of a Spring-based backend, which can then be linked to a pre-created frontend using a UI framework such as Twitter Bootstrap. Spring makes sense in the realization of complex business applications.
For companies, the framework and Java is generally a very good choice to implement the necessary technologies. In addition to pure Web frameworks, such as the Apache Struts competitor project, Spring is not limited to Web applications, but also enables the development of desktop solutions.
For simple applications, whether online or offline, Spring (and Java) is less suitable, although the realization of such projects is quite possible.
5. What does MVC mean?
Model-View-Controller (MVC) is a very popular software architecture style that allows you to be efficient & structured when developing a project.
The M, model represents the data and does not do anything else, so it does not depend on the views & controllers.
The V view (view) displays the data that the model contains to the user, eg form, button, etc … (A model can contain several views)
The C controller handles the user’s data, it depends on and interacts with the model as well as the view (In some cases it is possible that the view & the controller are the same object).
6. Why use the MVC model?
The MVC model allows you to be more efficient by giving you the ability to reuse the same code multiple times in other applications similar to the one you have and to separate your structure into multiple layers.
This combination offers you a better maintenance of your project and facilitates the task during the unit tests & allows you to work on several on the same project (ex: The back-end developer can set up the structure without intervening on the front- end, vice versa).
Another advantage is that there is little snapping between views, models, and controllers, which allows you to have a clean code where functions and classes can be easily rewritten and optimized.
The understanding of the MVC model can take some time to learn, but it is an essential knowledge and is worth learning because there are many frameworks whose model is that of Model-View-Controller and this in most popular programming languages, knowledge in many technologies and languages is becoming the norm for a developer.
7. Preview of Spring Benefits
If you are about to develop a major web project and are looking for a framework, Spring is a solution to consider. If you use Java specifically in your project, you can greatly facilitate your work by grouping modules in a flexible way. This will give you a powerful base architecture, which you will not be able to change, and you can concentrate on developing real business logic.
Here are 5 reasons to develop your project in the MVC framework
7.1 Scalable and easy to maintain
The Spring framework, and in particular the Spring MVC module, naturally implements a Control View Model. The use of XML configuration files makes it a remarkable, easily maintainable and scalable implementation.
In Spring MVC, the controllers are responsible for calling the various necessary methods of the business class and for conveying to the view the model containing all the data necessary to generate it. From the configuration files, HTTP requests are redirected by a dispatcher to the appropriate controller. There are different types of controllers that can redirect queries according to different criteria:
- full URL
- parameters passed in the URL
- user connected to the application
In addition, Spring MVC provides the ability to develop its own controller types to redirect more complex Url addresses. Finally, Spring MVC allows the use of regular expressions for URL redirection.
The transition from the model to the view is done via an Object map sorted by keyword. The view accesses it using the keyword of the desired Object.
Finally, unlike the native implementation of Tomcat with servlets, the controller will call the name of a view and no longer directed to a JSP page. The call to the view will be processed by a name resolver (configurable by XML) who will be responsible for returning the good view; it is not necessarily a JSP page. Indeed, Spring MVC allows the use of different formats for views: JSP, PDF, WORD, Excel, etc.
7.2 Provide tools for development
Spring Framework is known for its concept of dependency injection or Inversion of Control (IoC). What is less known is that Spring offers you all the tools for the development of your J2EE applications. With this framework, you have an abstraction layer for your transactions or JDBC access, an integration of the main market ORM Mapping solutions (Toplink, Hibernate, JDO, and iBATIS SQL Maps), AOP functionalities and an MVC framework for your applications.
7.3 Hundreds of thousands of features
The features offered by Spring are very numerous and the topics covered are constantly increasing as new versions and new projects are added to the portfolio.
7.4 Support of various web containers
All of Spring’s features can be used in a Java EE server and for the most part in a simple web container or standalone application.
It is widely used in the Java world, which makes it a de facto standard and provides a certain guarantee on the durability of the framework.
