In this article, I’ll provide a brief overview of the Java Struts Framework. After reading this essay, you will understand the following advice in its entirety.
Basics of MVC architecture:
The MVC pattern’s architectural components were developed to manage multiple facets of an application that is still being developed. The MVC design pattern helps to separate the presentation layer from the business logic.
What makes MVC crucial to developers?
MVC is the most common software design pattern used in the creation of apps and websites. The design pattern consists of.
handling and storing data as a model
1. It consists of the system’s business logic.
2. It contains all of the data from the program.
3. It exhibits the application’s present condition.
4. It consists of classes connected to the database.
5. The controller connects to the model, retrieves the information, and sends it to the view layer.
6. After the model interacts with the database, the data is stored in a database that is related to the model.
Observe the Graphical User Interface.
- It includes HTML, JSP, etc.
- It shows the user interface for the application.
- It is used to show the information that the controller is retrieving from model layer classes.
- This view layer displays the data on the application’s user interface.
Controller: The mind behind the program.
1. The controller serves as the link between the model and the view.
2. The controller translates inputs from the display to satisfy the requirement to retrieve/update data in the model.
3. The controller converts input from the view into a request for the model using logic, and the model then gathers the data. The data from the model is subsequently delivered by the controller to the view for enhanced display.
How Do Struts Work?
- Struts are frameworks created with a range of Java technologies, including JSP, Servlet, XML, and JSTL, as well as MVC architecture. This framework offers ready-to-use framework validation. The model layer is where Struts excels because it enables the integration of numerous Java technologies, including Spring, JDBC, Hibernate, etc.
- The open-source Struts framework is created by the Apache Software Foundation and is available for free download from the Apache website. It could be
- The two categories are Struts 1. X and Struts 2. X. Struts 1. X and Struts 2. X is very dissimilar to one another; Struts 2. X is meant to take the place of Struts 1.X. Because Struts 2. x, which is entirely based on the WebWorks2 framework, can easily retrieve the data that needs to be displayed to the user, it is also known as a pull-MVC architecture.
- Struts’ main controller is defined in the class that Action Servlet uses. The Action Servlet receives a request from the user and forwards it to the server, where it proposes the best major model and delivers the request to that model.
- More than just the web.xml and struts-config.xml files are used to support the application flow.
- A request is mapped by the struts-config.xml file to Action Forms, a simple POJO with UI-related properties, and Action classes. Every application-related setting is handled by the deployment descriptor Web.xml.
- Models are supported by a number of Java technologies, including JDBC, Spring, Hibernate, and others. It mostly concentrates on the business semantics of the application.
Structure for Struts 2
- The MVC design pattern is the foundation of the well-known Struts2 Framework for web applications. Not only a new version of Struts 1 but a thorough overhaul of the Struts architecture.
- The Webwork framework was initially built on top of Struts with the intention of giving developers a better, more advanced framework that is based on Struts. After some time, the Struts community and the Webwork framework joined forces to create the acclaimed Struts2 framework.
