Prime Java Frameworks |

Proper now, in 2023, Java is the third hottest programming language on the planet with greater than 9 million Java builders worldwide (Python and C occupy the highest 2 spots respectively). Java’s enduring success will be attributed to some key components:

  • It’s a platform-independent language (as highlighted by Java’s “write as soon as, run wherever” motto)
  • It follows the object-oriented programming paradigm
  • Its syntax is much like different well-understood languages akin to C++

Within the 20+ years that Java has been round, many wonderful Java frameworks have proliferated that permit programmers to effectively construct internet and cell purposes, microservices, and REST APIs that run on the Java Digital Machine (JVM). On this programming tutorial, we’ll look into a number of of the most well-liked Java frameworks for internet improvement, and listing the important thing execs and cons of every.

Spring Framework

Spring Java Framework

Virtually all of the Prime Java Framework lists give Spring the coveted #1 spot. An open-source framework particularly meant for Enterprise purposes, Spring took the event world by storm by introducing the idea of dependency injection and aspect-oriented programming options. Firms who use Spring embody giants akin to eBay, Dick’s Sporting Items, and Netflix.

Spring permits builders to create loosely coupled modules whose dependencies are dealt with immediately by the framework. Spring is s a reasonably intensive framework, protecting a wide range of options from safety to configuration. Happily, Spring’s many options should not troublesome to study, due to a wealth of documentation and a particularly lively neighborhood.

The configuration, setup, construct, and deployment processes all require a number of steps – maybe too many in the event you’re engaged on a smaller challenge. Spring Boot (a micro framework that runs on prime of the Spring Framework) is an answer for this downside, because it lets you arrange your Spring utility quicker, with a lot much less configuration. The Spring Boot framework was invented with quickness in thoughts, by vastly decreasing the quantity of configuration required for brand spanking new tasks.

  • Massively in style and really steady framework
  • Versatile configuration
  • Unfastened coupling (as a result of dependency injection)
  • Simple-to-test purposes (as a result of dependency injection)
  • Makes use of POJOs (Plain Previous Java Objects)
  • Intensive documentation
  • Energetic neighborhood

Cons of Spring Framework:

  • Complexity (steep studying curve)
  • Builders want to write down lots of boilerplate code (except you employ Spring Boot)

Struts Java Framework

Struts Java Framework

Apache Struts is a sturdy open-source framework for internet utility improvement. Having been round over 20 years now, it’s one of many oldest Java frameworks in use as we speak! It follows the MVC (Mannequin-View-Controller) architectural sample and extends the Java Server Pages (JSP) API. In a conventional servlet-JSP strategy, when the consumer submits a kind, the knowledge both goes to a servlet for processing or straight to subsequent JSP. This could grow to be problematic in advanced purposes because the “View” or presentation layer ought to ideally not have enterprise logic.

Struts separate the View, Controller and the Mannequin (knowledge) and supplies the binding between every by way of a configuration file struts-config.xml. The controller is an ActionServlet the place you may write templates for the View and the consumer knowledge is maintained utilizing the ActionForm JavaBean. The Motion object is liable for forwarding the applying move. The View is maintained by a wealthy set of tag libraries.

Struts are straightforward to arrange and supplies way more flexibility and extensibility over the normal MVC strategy utilizing servlets and JSP alone. Furthermore, you may combine Struts with different Java frameworks to carry out duties that aren’t constructed into the platform. As an illustration, you should utilize the Spring plugin for dependency injection or the Hibernate plugin for object-relational mapping. Struts additionally lets you use completely different client-side applied sciences akin to Jakarta Server Pages to construct the front-end of your utility.

Professionals of Apache Struts:

  • Secure and mature framework
  • Espouses conference over configuration
  • Extensible through plugins
  • Simple to combine with different Java frameworks and instruments
  • Helps internet applied sciences (REST, AJAX, JSON)

Cons of Apache Struts:

  • Not your best option for creating server-side elements that may render on the front-end
  • No built-in safety mechanism; solely safety suggestions that you must apply your self

Grails Java Framework

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 concentrate on the job with out having to commit lots of time on configuration. The Grails framework can be straightforward to get the grasp of and use successfully in on a regular basis work for the typical Java skilled.

Like Java, Groovy is an object-oriented language. Its syntax can be very similar to that of Java, each in fashion and that it compiles to JVM (Java Digital Machine) bytecode. Grails is constructed on prime of Spring Boot to utilize its highly effective options like dependency injection. That, together with trendy software program improvement rules akin to conference over configuration, opinionated APIs to implement greatest practices, and wise defaults all mix to make a successful framework.

Programmers can present extra performance to their purposes by creating customized plug-ins. Many of those discover their approach to neighborhood websites the place builders share their creations.

Professionals of Grail Framework:

  • Constructed on prime of Spring Boot
  • Seamless integration with Java libraries and instruments
  • Conference over configuration (with wise defaults)
  • Asynchronous capabilities
  • Excessive-quality documentation and tons of studying supplies

Cons of Grails Framework:

  • You should know Groovy in an effort to write Grails apps

Forms of Java Frameworks

To this point, we’ve targeted on very generalized enterprise-level Java frameworks that facilitate all levels of utility improvement. There are additionally frameworks for particular duties or tiers, akin to:

  • Frontend frameworks that allow you to create the view layer
  • ORM (object-relational mapping) and persistence frameworks that will let you work together along with your database
  • Java backend frameworks that assist with creating microservices and REST APIs
  • Java frameworks constructed on prime of different Java frameworks

We talk about a couple of of those different forms of Java frameworks under.


Hibernate Java Framework

Hibernate is an object-relational mapping framework that facilitates communication between your Java purposes and relational database administration techniques (RDBMSs).

One of many challenges when working with RDBMSs is that programming languages and RDBMSs deal with knowledge in another way, which may result in kind mismatch points. Often called “Paradigm Mismatch”, this difficulty is very pronounced for object-oriented (OO) languages as a result of they construction knowledge as a hierarchy of objects, whereas relational databases maintain the identical knowledge in tables. Therefore, builders will encounter mismatch issues each time lessons don’t line up completely with the database tables, i.e., there are extra lessons in your object mannequin than the variety of out there tables inside your relational database or vice versa.

Hibernate supplies programmers with the instruments to realize knowledge persistence with out having to fret about object mapping. It goals to realize persistence, which means that the info created/utilized by the applying ought to proceed on when the applying just isn’t being utilized or there aren’t any lively classes. Initially constructed for relational databases, its latest variations present assist for NoSQL knowledge shops as nicely. Hibernate comes with highly effective APIs and a number of other helpful instruments like Mapping Editor, Wizards, and Reverse Engineering. Many massive corporations together with Platform, DAILY HOTEL, IBM, and Dell use Hibernate of their tech stacks.
