Why Use Struts Framework?

• We'll discuss the capabilities of the Java Struts Framework. Unintelligible language This is one of the most widely used Java frameworks. Now let's read the article.
• Apache Struts is a free and open-source web application framework for developing Java EE web applications. It uses and expands the Java servlet AP to encourage developers to use a model-view-controller (MVC) architecture.
• The Struts Framework is a suggested technique for developing Web applications with solid architecture. It has the following features:
• Free software
• Making the distinctions between each level explicit using the Model-View-Controller (MVC) design paradigm

1. Modeling of application state

2. Data visualisation (JSP, HTML)

3. Controller: JSP Model 2 Architecture's struts-config.xml

• The single core file contains information about request mapping and application routing and handles application flow routing.
• Only the View and Controller levels are filled in by the Struts Framework itself. The Model layer is within the developer's control.

Struts pro:

JSP tag mechanism usage

The tag feature promotes code reuse by separating Java code from the JSP file. This capability enables seamless integration with tag-based authoring-compatible JSP-based development tools.

Tag database

Why reinvent the wheel or build a new tag library? If the library doesn't have what you're looking for, contribute. Struts also provide a starting point if you wish to learn JSP tag technology.

Free software

One advantage of open source software is that you can inspect the source code and request that anyone else using the library review it. Many eyes are needed for a good code review.

MVC implementation example

Struts can offer advice if you want to develop your own MVC implementation.

Control the issue area

To address a problem and make it manageable, divide and conquer is an excellent method.

An MVC 2 implementation is Struts

Struts is an MVC 2 design that can be reused and is made up of a collection of interconnected classes, servlets, and JSP tags. This description classifies Strut as a framework as opposed to a library; nonetheless, Struts also contains a substantial tag library and utility classes that function independently of the framework.

Overview of Struts

customer browser

A client browser's HTTP request results in an event. The Web container will send back an HTTP response.

Controller

After receiving the request from the browser, the Controller determines where to send it. The Controller is a Struts-compatible command design pattern that is implemented as a servlet. The struts-config.xml file contains the Controller's configuration.

Business sense

The application's flow is regulated by the business logic, which also alters the state of the model. An Action class in Struts acts as a straightforward protective shell for the essential business logic.

A good state

The model shows how the program is now functioning. The business objects alter the application state. As opposed to the permanent ActionForm bean, the session- or request-level ActionForm bean represents the Model state. The JSP file retrieves information from the ActionForm bean using JSP tags.

View

The view is nothing more than a JSP file. There are only tags; flow logic, business logic, and model information are not present. Tags are one feature that distinguishes Struts from other frameworks like Velocity.

Design objectives

• The model, or the application logic that interacts with a database, is neatly separated from the view, or the client-facing HTML pages, and the controller by Struts (instance that passes information between view and model). It is simpler to develop templates for the view or presentation layer when using the controller given by Struts (a servlet named ActionServlet, though XML/XSLT and Velocity are also supported). The web application programmer is responsible for creating the trust-config.xml configuration file, which links the model, view, and controller, as well as the model code.
• When the controller receives requests from the client in the form of "Actions" listed in the configuration file, it must call the application-specific model code in order to interact with it. The model code's "ActionForward" string tells the controller which output page to send to the client. Data is transmitted between the model and display using certain JavaBeans. It can read and write the content of these beans from the display layer without any embedded Java code thanks to a strong custom tag library.
• Struts also support multilingualism, have tools for validating data entered into online forms, and include a template method called "Tiles" that, for instance, enables the display layer to be created from the distinct header, footer, and content components

• Apache Struts 2 uses Inversion of Control (IoC) and the tried-and-true Model-View-Controller architectural model when developing enterprise-class Java-based online applications (MVC). Struts 2 is the best choice for building aesthetically pleasing and highly interactive Web 2.0 applications because it comes with native support for AJAX.
• The well-known Struts framework is improved with Struts 2. Its goals are the same as those of Struts: to boost the productivity, extensibility, maintainability, and scalability of web application developers. However, Struts 2 also supports Aspect-Oriented Programming (AOP), which makes use of interceptors to produce very modular code. Additionally introduced are strong features like an extensible architecture for plugins, connection with JavaServer Faces (JSF), and XML-free configuration.

What benefits may you get from using Struts?

• The Struts Framework has the inherent benefit of having the Front Controller design fully developed. Working with Struts is a reliable and totally flexible architecture, too.
• Struts have the ability to set up all underlying components using XML and certain class-based controlling elements, populating Java Beans with HTML form components and validating those parts.
• To fully support internationalization, resource bundles are offered for all HTML components.
• Tag libraries are a sophisticated way to solve form-related issues and are easy to integrate with JSPs.
