Proper now, in 2023, Java is the third hottest programming language on the earth with greater than 9 million Java builders worldwide (Python and C occupy the highest 2 spots respectively). Java’s enduring success might be attributed to some key elements:
- it’s a platform-independent language (as highlighted by Java’s “write as soon as, run anyplace” motto)
- it follows the object-oriented programming paradigm
- its syntax is much like different well-understood languages comparable to C++
Within the 20+ years that Java has been round, many glorious Java frameworks have proliferated that enable programmers to effectively construct net and cellular functions, microservices, and REST APIs that run on the Java Digital Machine (JVM). On this programming tutorial, we are going to look into a number of of the preferred Java frameworks for net improvement, and record the important thing execs and cons of every.
Spring Framework
Virtually all of the Prime Java Framework lists give Spring the coveted #1 spot. An open-source framework particularly meant for Enterprise functions, Spring took the event world by storm by introducing the idea of dependency injection and aspect-oriented programming options. Firms who use Spring embrace giants comparable to eBay, Dick’s Sporting Items, and Netflix.
Spring allows builders to create loosely coupled modules whose dependencies are dealt with immediately by the framework. Spring is s a reasonably in depth framework, overlaying quite a lot of options from safety to configuration. Happily, Spring’s many options aren’t troublesome to study, due to a wealth of documentation and an especially energetic group.
The configuration, setup, construct, and deployment processes all require a number of steps – maybe too many in case you’re engaged on a smaller challenge. Spring Boot (a micro framework that runs on high of the Spring Framework) is an answer for this downside, because it permits you to arrange your Spring utility sooner, with a lot much less configuration. The Spring Boot framework was invented with quickness in thoughts, by enormously decreasing the quantity of configuration required for brand new tasks.
Execs of Spring Framework:
- vastly standard and really secure framework
- versatile configuration
- unfastened coupling (as a result of dependency injection)
- easy-to-test functions (as a result of dependency injection)
- makes use of POJOs (Plain Outdated Java Objects)
- in depth documentation
- energetic group
Cons of Spring Framework:
- complexity (steep studying curve)
- want to put in writing a whole lot of boilerplate code (except you employ Spring Boot)

Struts Java Framework
Apache Struts is a strong open-source framework for net utility improvement. Having been round over 20 years now, it’s one of many oldest Java frameworks in use in the present day! It follows the MVC (Mannequin-View-Controller) architectural sample and extends the Java Server Pages (JSP) API. In a standard servlet-JSP method, when the consumer submits a kind, the knowledge both goes to a servlet for processing or straight to subsequent JSP. This could turn into problematic in advanced functions because the “View” or presentation layer ought to ideally not have enterprise logic.
Struts separate the View, Controller and the Mannequin (knowledge) and offers the binding between every by means of a configuration file struts-config.xml. The controller is an ActionServlet the place you possibly can write templates for the View and the consumer knowledge is maintained utilizing the ActionForm JavaBean. The Motion object is liable for forwarding the applying stream. The View is maintained by a wealthy set of tag libraries.
Struts are simple to arrange and offers rather more flexibility and extensibility over the normal MVC method utilizing servlets and JSP alone. Furthermore, you possibly can combine Struts with different Java frameworks to carry out duties that aren’t constructed into the platform. For example, you need to use the Spring plugin for dependency injection or the Hibernate plugin for object-relational mapping. Struts additionally permits you to use completely different client-side applied sciences comparable to Jakarta Server Pages to construct the front-end of your utility.
Execs of Apache Struts:
- secure and mature framework
- espouses conference over configuration
- extensible through plugins
- simple to combine with different Java frameworks and instruments
- helps net applied sciences (REST, AJAX, JSON)
Cons of Apache Struts:
- not your best option for creating server-side parts that may render on the front-end
- no built-in safety mechanism; solely safety ideas that it’s important to apply your self
Grails Java Framework
Grails is an open-source, Groovy-based framework that’s particularly prevalent within the sphere of e-commerce retailers. Builders have a tendency to decide on this framework as a result of it lets them give attention to the job with out having to dedicate a whole lot of time on configuration. The Grails framework can also be simple to get the grasp of and use successfully in on a regular basis work for the common Java skilled.
Like Java, Groovy is an object-oriented language. Its syntax can also be very similar to that of Java, each in type and that it compiles to JVM (Java Digital Machine) bytecode. Grails is constructed on high of Spring Boot to utilize its highly effective options like dependency injection. That, together with fashionable software program improvement rules comparable to conference over configuration, opinionated APIs to implement finest practices, and smart defaults all mix to make a successful framework.
Programmers can present extra performance to their functions by creating customized plug-ins. Many of those discover their technique to group websites the place builders share their creations.
Execs of Grail Framework:
- constructed on high of Spring Boot
- seamless integration with Java libraries and instruments
- conference over configuration (with smart defaults)
- asynchronous capabilities
- high-quality documentation and tons of studying supplies
Cons of Grails Framework:
- you want to know Groovy with a view to write Grails apps
