Top Java Frameworks

I remember my ode to Java experience sucked big time on notepad!

The giant wall of white clipboard made Java look like a daunting programming language. I know this will offend many traditional Java experts, but I’ve seen beginners getting appalled by the long, crazy, complex codes and ideas terribly.

Fortunately, Java frameworks exist. Phew!! They exist to solve all the foundational problems that you face while writing software.

And you can’t discount the additional functionality that the framework tools let you add to your code (without much of a coding discomfort.)

It makes us believe you’re looking for the top Java frameworks in 2021

So we researched the top best Java frameworks, so you don’t have to. Are you ready to have the best one for you? Let’s go ahead:

Java Framework #1 Spring

Spring is a compelling lightweight framework you can use to solve many technical problems.

What separates its well-defined tool from other frameworks? Well, it supports several web applications keeping Java as a primary programming language.

Features of Spring

  1. Extremely lightweight
  2. Transaction management
  3. Aspect-oriented programming
  4. Dependency injection
  5. YAML support
  6. Properties files
  7. Admin features
  8. Application events & listeners
  9. Inversion of control
  10. JDBC exception handling

Benefits of Spring

  1. Great for Enterprise application development (through POJOs)
  2. Solving the difficulties related to Enterprise application development
  3. Easily integrable with other frameworks
  4. You can use multiple modular frameworks as per application requirement
  5. Spring transaction management for local transaction in small apps
  6. Application testing is extremely easy

Java Framework #2 Hibernate

Easily the best of the Java frameworks, Hibernate has remarkable capability in performance-oriented programming. It extends Java’s persistence API support.

As with Spring, Hibernate is an extremely lightweight, open-source framework.

Features of Hibernate

  1. Lightweight
  2. Open-source
  3. Hibernate query language
  4. High performance
  5. Object-relational mapping (ORM)
  6. Caching
  7. Independent of database
  8. Lazy loading
  9. Scalable
  10. Easy to learn and implement

Benefits of Hibernate

  1. ORM helps gain control over the application and database design
  2. Ensures the automatic connection between the application’s objects with the database tables
  3. It can be connected with any database, including MySQL, Oracle, Sybase, etc.
  4. HQL is a more powerful language than SQL (dynamic profiling and pagination)
  5. Supports first and second level caching mechanism
  6. Helps multiple transactions without affecting others
  7. Hibernate adapts itself in any environment

Java Framework #3 Struts 2

Struts are open-source software that’s designed to inherit the Java Servlet API properties.

It makes the developing environment super easy for Java developers. The free software is also great for creating elegant and contemporary web applications.

Struts 2 = webwork + struts1

Features of Struts 2

  1. Simplified designs
  2. Easy to modify tags
  3. Various tags support
  4. AJAX support
  5. Easy plugins
  6. POJO based actions
  7. Tag support
  8. Theme & Template support
  9. Integration support
  10. Configurable MVC components
  11. Stateful checkboxes

Benefits of Struts 2

  1. Your code is not tightly coupled with Servlet API or Struts framework
  2. Developers have the advantage of using other technologies
  3. You can use annotation results to reduce the length and complexity of code
  4. You also have access to multiple views which go beyond JSP to freemarker and velocity
  5. Ajax-enabled and theme-based tags are incredible tag features
  6. The framework fetches data from ValueStack and does all the type conversion (ultimately leads to shorter code).

Java Framework #4 Wicket

Wicket is one of the recently developed Java frameworks, but we love its simplicity in component-based application development.

You can say it’s one of the few living Java server-side web frameworks.

Features of Wicket

  1. POJO based actions
  2. Various tag support
  3. Various result types
  4. Separation of concerns
  5. Theme and Template support
  6. Configurable MVC components
  7. AJAX support
  8. Multi-tab, multi-window support
  9. Transparent back button support
  10. Reusable components
  11. Integration support

Benefits of Wicket

  1. It has all real Java objects. These objects support inheritance, encapsulations, and events
  2. Wicket is secure by default
  3. Extremely easy to customize and localize the display
  4. You can customize most operations with factory methods (highly extensible)
  5. Best of all: you can develop AJAX components without getting yourself involved with writing Javascript

Java Framework #5 GWT

GOOGLE WEB TOOLKIT! That’s GWT for you. The open-source toolset has a potpourri of tools and libraries that are needed for your Javascript-based application development.

If you’re looking to build and optimize complex browser-based applications, GWT it is!

Features of GWT

  1. Reusable User-Interface components (also extensively dynamic)
  2. Easy RPC mechanism
  3. Unit testing integration
  4. Browser History Management
  5. Java Debugging (full-featured)
  6. Brilliant support for localization and internationalization
  7. Cross-browser exception handling

Benefits of GWT

  1. Learning GWT is no rocket science if you know Swing or AWT
  2. Easy to create a responsive web application (reduce chattiness on the server-side)
  3. GWT is not an all or none proposition. The migration is super simple, from a typical web application to a GWT application. That too, iteratively.
  4. The IDE support is exceptional for GWT.
  5. GWT has an in-built browser back button while using AJAX. It could be a great relief if you’re a developer. 馃槈

Some other Java Framework picks:

  • Dropwizard
  • Vaadin
  • Play
  • Grails
  • Blade

Final thoughts

So I have written the best five picks for the Java frameworks. Now you can choose the proper framework for the right job! These tools make the Java experience worth living.

Also, don’t forget to look at these stats that say Spring is prevalent among 86% of the users. They’ll really help you with making informed decisions.
