Best Java Web Frameworks to Build Scalable Applications in 2021

Any business looking to build an application understands the struggles of cost, development, and scalability. Most importantly, building a scalable application can be a rather daunting challenge for organizations dealing with large data sets and high request rates. To solve this problem, high-end developers and companies suggest using the best Java Web frameworks to build scalable products and applications.

Now, the question is, what is a Java web framework? Well, to give a short answer, Java Frameworks uses pre-written code and Java programming language, allowing software developers to develop scalable apps in a relatively short time. Since Java virtual machine follows the ‘Write once, Run anywhere’ principle, it can easily scale web applications according to the needs of any business. In this article, we will be exploring the best Java web frameworks to build scalable business apps to help you elevate your business experience.

6 Best Java Web App Development Frameworks

When it comes to business talk, time is money. Well, working with Java web frameworks allows businesses and developers to save both time and money while achieving consistent results. That's why more and more development agencies are opting for app development frameworks. Now, you must understand that each framework is different from the other, and all of them are not equally good. So, choosing a reliable Java web app development framework isn't as easy as it sounds.

Therefore, in this article, we are going to share the 6 best Java Web Frameworks to build reliable and scalable applications in 2021. Although there are many other frameworks available, we have filtered out the top 6 that provide the maximum benefits and can work in the majority of scenarios. So, without further ado, let’s take a look at the best Java Web Frameworks of 2021.

1- Spring Framework

The Spring Framework is an application development framework and inversion of the control container for the Java platform. Owing to its size and transparency, the spring framework is at the top of the best Java web frameworks list.

Pros:

  • Lightweight: It is lightweight due to its POJO (Plain Old Java Object) implementation. This does not force the programmer to inherit any interface.

  • Flexible: It provides flexible libraries which let the developer choose XML or Java-based annotations for configuration options.

  • Secure: It monitors third-party dependencies closely.

  • Fast: It features fast-optimized execution, which ultimately maintains performance.

Cons:

  • Complexity: The framework is a little complex to understand and requires expertise.

  • Parallel Mechanism: It features multiple options, which can often create confusion and lead to wrong decisions for amateurs.

2- Struts

The Struts Framework is used to create the base for web applications. It basically functions on Model-View-Controller (MVC) pattern, which provides business logic, presentation logic, and navigation role.

Pros:

  • Central Organization: It features a central organization architecture that builds and controls MVC-based web applications.

  • Clean Separation: There is a clean separation between code for presentation and code for functionality.

  • Ease of Use: It offers built-in extensible authentication and validation.

  • Development: It allows easy integration and modular development with other components.

Cons:

  • Rigidity: Unfortunately, it is a non-flexible framework and imposes a particular way of coding.

  • Understandability: A higher understanding is required, which eventually increases the learning curve.

  • Adaptability: It does not suit smaller applications.

3- Javaserver Faces (JSF)

Javaserver Faces (JSF) is one of the most popular Java frameworks widely being used in 2021 to build scalable applications. Its user interface layer development allows developers to build component-based user interfaces for web applications.

Pros:

  • Productivity: It enhances the overall productivity by allowing reusable components in terms of design and concept. It allows the workflow to be more consistent and productive.

  • Ease of Use: It offers less confusion for developers as the JavaScript code is embedded as part of the component.

  • Concepts: It offers a good concept of action and action-listener for button invocation as well as validator and converter.

Cons:

  • Bookmarking: It does not offer the bookmarking feature in the specifications.

  • Understandability: It has a rather complex understanding and, thus, also comes with a steep learning curve.

  • Features: Managed bean and phase listener have no tight coupling.

4- Play Framework

Play Framework is rapidly becoming one of the most popular Java Frameworks for web development in the market. It is scalable, powerful, and easily programmable in the Scala language. Most configurations in this framework are either default or automatically set.

Pros:

  • Speed: Its fast speeds allow developers to work on multiple projects at the same time.

  • Testing: Testing applications is easy and provides authentic results.

  • User Interface: It has an intuitive user interface.

Cons:

  • Programming: Scala is a complicated programming language.

  • Compatibility: It often faces issues with backward compatibility in newer versions.

  • Instability: It offers a lot of plugins, but, unfortunately, most of these plugins are unstable.

5- Google Web Toolkit (GWT)

GWT is an open-source set of development tools that allows developers to create and maintain complicated browser-based applications in Java. It enables the productive development of web applications of high performance without having the developer be an expert.

Pros:

  • Understandability: It has the least learning curve as compared to the rest of the frameworks.

  • User Interface: It offers highly responsive web applications with reduced traffic on the server-side and heavy lifting on the client-side.

  • Compatibility: It is easy to migrate from a common web application to GWT.

Cons:

  • Speed: Java to JavaScript compilation is slow relatively.

  • Development: It has a lot of versions, and it is hard to stay up to date with all the functions, interfaces, and events.

6- Vaadin

Vaadin is a mature web framework, and it is used to develop big internet applications. It is one of the best Java GUI frameworks in 2021 and makes building web-based GUIs feel like developing a desktop application. In addition, it comes with built-in support for AJAX and Javascript.

Pros:

  • Understandability: It offers a flat learning curve.

  • Development: It allows fast development.

  • Documentation: It has an active community and good documentation.

Cons:

  • Load: It has a higher load on the server and network, which can often cause problems and glitches.

  • GUI: It is unsuitable for fancy GUIs.

Final Thoughts:

Different frameworks work out best for different scenarios. For Example, the development of a complicated web application demands the use of a framework with more complex development options. The amount of time, experience, and learning you have will depict how complicated a framework you can work with along with other technicalities such as speed, network, traffic, and adaptability. Always make sure to study the Java Framework, its functionalities, as well as its documentation and prototypes to analyze whether it's a perfect fit for your web application development project.
