There is no doubt that Java is one of the most used programming languages, and therefore, most demanded in the world of programming. In this article we will delve into the seven best Java frameworks, alternatives to not working with pure code but equally efficient, highlighting the pros and cons of each one so that the user's choice is correct.
1. Spring MVC
Despite being a veteran framework (more than ten years since its first version), it is still at the top of the wave. After its expansion into the MVC (Vista Viewer Model), spring continued to evolve into a large-scale Java framework for Internet applications, offering engineers a powerful tool for web application development as well as security projects. Being a favorite for programmers, it offers a wide range of services: API REST, SOAP web services, security, etc. Another benefit is that there is a large developer community working with spring and therefore there is a huge source of documentation.
Pros and cons
Spring is not number 1 for any reason. These are the most outstanding:
• Simplified injection of test data using POJOs.
• Modularity improved, resulting in better readability of the code.
• Flexible coupling between the different modules.
• Injection of dependencies with flexible use.
Although we cannot consider it a disadvantage, since there is a lot, it is true that Spring MVC maybe should be easier to learn for novice developers. They often complain that the learning curve at the beginning is too steep. Some parts of the code may be poorly documented and initial learning can be difficult. In addition, the information is sometimes different between versions. However, most engineers working with Java consider it one of the best frameworks, if not the best.
2. Struts 2
Another of the main Java frameworks used by most modern software engineers is the successor to Apache Struts 1, version number two. This framework is a great find for developers who build new web applications with Java EE . Apache has delivered a huge set of tools to create enterprise-oriented web applications by optimizing the development process from start to finish and post-commissioning maintenance. Struts 2 is the right choice if the web is going to have a high data load, such as a broadcast web.
Pros and cons
It is a luxury not to have to implement the Action class, since it is already incorporated. The code for setting up repeats is no longer necessary because the interceptors deal with it . However, you may not like this framework for one reason: many developers do not consider it agile enough to work with it.
The Java mapping framework breaks with object-relational impedance and mismatches by replacing access to high-level databases . Hibernate is equipped with great features that help back-end developers access data. It is an advanced ORM framework that allows to perform the operation in the database of Java objects (entities). It is a continuous concept that uses Hibernate cache to bring data from the Java environment to the database.
Pros and cons
Hibernate allows you to communicate with any database using minimal code alterations by reducing the gap between objects and relational words. Further:
• Oracle, DB2, MySQL or, Hibernate are independent DB.
• Cache mechanism to look for database errors with similar queries.
Despite the obvious advantages, Hibernate does not allow multiple inserts , avoiding the queries that JDBC does. Nor is this framework recommended for small-scale projects.
Being part of Java EE, Java Server Faces has Oracle support. Although not the best framework for fast development of Java, it is very easy to use because there is a lot of documentation provided by Oracle. In addition, unless you leave your Java EE environment, JSF not only has no external dependencies, but has many features, such as libraries and tools (including a set of tools for creating user-friendly interfaces).
Pros and cons
As we mentioned, JSF is an integral part of Java EE. Therefore, developers work on IDE software, and are heavily supported by a leading provider in the industry. On the contrary, JavaServer Faces is too difficult to understand for those whose prior experience and skills in basic web development are not strong enough.
This framework became one of the main and most popular for business application development . Using a well-known component approach, it gives developers less weight when communicating changes made to the browser. A broad set of user interface components, along with various widgets and controls, allows programmers to create more than interesting applications in no time.
6. Goggle Web Toolkit
Pros and cons
With the Google Web Toolkit, you get the unique codebase (both in the browser and on the Java programming server) that facilitates development and debugging processes . Easy complementation with other technologies allows programmers to integrate GWT widgets into web pages. The ability to customize widgets is another important aspect that can be created with the help of this framework. However, for a web page designer, GWT is not the best Java framework to choose; Is not recommended for those who work with HTML flat and intend to incorporate dynamic content later.
This particular web framework is considered as a dynamic tool that improves the productivity of the engineers due to its APIs , its good default values, as well as its paradigm configuration convention. The perfect integration of Java makes this one of the best frameworks valued by developers around the world. A powerful set of tools, such as spring-powered dependency injection and various add-ons, offer everything you need to create modern web applications.
