Java is still the world\’s third most popular programming language in 2023. It has a large ecosystem and over 9 million Java developers worldwide. Java\’s popularity can be attributed to a few important features: it is a platform-independent language (write once, run anywhere) that adheres to the object-oriented programming paradigm and is simple to comprehend, create, and debug.

There are numerous ways to construct Java applications due to the language\’s maturity (the most recent LTS (long-term support) release is Java 17) and popularity. While you can always create Java code from scratch, several good Java frameworks allow you to construct web and mobile applications, microservices, and REST APIs that operate effectively on the Java Virtual Machine.

In this comprehensive guide, we\’ll look at a few major Java frameworks used in web development and outline the primary benefits and drawbacks of each.

What exactly are Java frameworks?

Java frameworks are software libraries designed to make the development of Java applications simpler and faster. They are pre-written Java code, classes, templates, components, and other structures that can be used as the foundation for your program.

The greatest Java frameworks have been thoroughly tested and enforce the usage of proper development standards. They let you concentrate on your apps’ business logic rather than creating basic functionality such as database connectivity or exception handling.

However, because not all Java frameworks serve the same goal, selecting one is more than a matter of personal preference. Some allow you to build full-stack Java web applications, while others focus on either the frontend or the backend, and there are other frameworks for specific tasks like database management. In some circumstances, you may want to use more than one framework at the same time, thus it\’s critical to understand how various Java frameworks compare to and integrate.

Why are frameworks used?

Creating sophisticated Java applications from scratch takes a long time, and including a framework in your stack makes this process easier. Many basic capabilities, such as data retrieval, security, and privacy, are required by practically every application. Many of these capabilities are included in the top Java frameworks, so you don\’t have to reinvent the wheel every time you start a new project.

They also give a software architecture that aids in the development of well-structured applications. Because these frameworks are actively being developed, you can ensure that your Java code is routinely updated and thoroughly tested.

Let us now look at the most popular Java frameworks.

Spring Framework: Enterprise-level Java application framework

Spring is the most well-known and popular Java framework, with a massive ecosystem and an active community. It enables the development of enterprise-level Java applications, web services, and microservices.

Spring began as a dependency injection tool but has since evolved into a full-fledged application framework. It provides a comprehensive programming and configuration model that includes support for generic operations like creating database connections and managing exceptions. Aside from Java, the framework may also be used with the Kotlin and Groovy programming languages, both of which run on the Java Virtual Machine.

Pros: – massively popular and extremely reliable framework – adaptable configuration – sloppy coupling (due to dependency injection) – simple-to-test applications (due to dependency injection) – makes use of POJOs (Plain Old Java Objects) – comprehensive documentation – a vibrant community

Cons: complication (steep learning curve) – a lot of boilerplate code must be written (unless you use Spring Boot).

Struts: MVC framework for enterprise-level Java applications

The Apache Software Foundation maintains and develops Struts, a full-featured Java web application framework. It\’s a strong platform with a large community, and it\’s frequently compared to the Spring Framework. Struts enables the development of enterprise-level Java applications that are simple to maintain over time.

It has a plugin-based architecture and adheres to the MVC (Model-View-Controller) software design paradigm. Plugins allow the framework to be extended to meet the needs of various projects. Struts plugins are simple JAR packages, therefore they are portable and can be added to your app\’s classpath. Some plugins are included with the framework (JSON, REST, Config Browser, and so on), while others can be obtained from third-party sources.

Pros: – stable and mature framework – preference for convention over configuration – extendable through plugins – simple to interact with other Java frameworks and technologies – is compatible with web technologies (REST, AJAX, JSON)

Cons: – no security mechanism (see their security advice, which you must implement yourself)

Hibernate: Object-relational mapping framework for a better database communication

Hibernate is a reliable object-relational mapping framework that enhances communication between Java programming and relational database management systems (RDBMSs).

When working with object-oriented (OO) languages like Java, you\’ll run across a problem known as an Object-Relational Impedance Mismatch (also known as Paradigm Mismatch). Data is handled differently in OO languages and RDBMSs, which might lead to mismatch issues. OO languages arrange data as a hierarchy of objects, whereas relational databases store the same data in tables. When the number of classes in your object-oriented model exceeds the number of available tables in your relational database, you have a mismatch.

Pros: – object-oriented interface (no SQL interfaces required) – allows any class or data structure to be persistent – supports different fetching strategies – automatic versioning and time stamping – scalability – extensibility and configuration

Cons: sluggish performance for complex queries – difficult learning curve

That concludes our Java framework comparison. Because each of these frameworks serves a different function, understanding their benefits, drawbacks, and capabilities is critical before selecting one or more for your specific Java project.

To select the finest Java framework for your application, you must consider your goals, budget, and team knowledge, among other things.

Several resources on SnapStack\’s team who are Java specialists are eager to give the best solutions. If you require such resources, please contact us at contact@snapstack.cz or through our social media channels.

Enjoy the remainder of your week, and we\’ll see you next Friday. Cheers.

The shift towards skills-based hiring: A new era of talent acquisition

In today’s fast-evolving job market, there’s a growing trend towards skills-based hiring, which places a stronger focus on a candidate’s practical abilities rather than traditional qualifications like degrees or titles. This shift is fundamentally changing how companies approach recruitment, resulting in more dynamic and diverse workforces.

Organizations are increasingly recognizing that skills-based hiring can lead to better job performance, role fit, and inclusivity, which is driving widespread adoption of this model.

What is skills-based hiring?

Skills-based hiring is a recruitment strategy where employers focus on a candidate’s specific skills and competencies rather than their formal education or past job titles. For instance, companies may prioritize technical skills, such as proficiency in certain programming languages or software, or soft skills like communication and problem-solving, over traditional criteria like a four-year degree. As noted by SHL, this approach allows companies to uncover hidden talent and focus on candidates’ potential, helping organizations foster diversity, equity, and inclusion.

Why skills-based hiring is gaining popularity

  1. Access to a wider talent pool
    Traditional hiring methods often exclude individuals who may not have formal degrees but possess valuable skills. By adopting skills-based hiring, companies can tap into non-traditional talent pools, including self-taught professionals and those from different socio-economic backgrounds. As Workable reports, nearly 45% of companies in 2024 are expected to drop degree requirements for many roles.
  2. Improved role fit and performance
    Skills-based hiring often leads to a better match between the candidate and the job. Focusing on specific, measurable skills means that employees are more likely to succeed in their roles from day one. According to BCG, hiring based on skills is five times more likely to predict job performance than hiring based solely on degrees. By assessing candidates based on real-world competencies, employers can ensure a higher level of job readiness and productivity.
  3. Fostering lifelong learning and agility
    As companies face rapid technological changes, employees need to continuously upskill to remain relevant. A skills-based approach promotes a culture of lifelong learning, encouraging employees to focus on acquiring new competencies rather than relying on outdated credentials. This mindset aligns with the needs of industries such as IT and digital marketing, where practical skills and staying current with trends are crucial .
  4. Reducing bias and increasing diversity
    Traditional hiring processes can unintentionally reinforce biases related to education or socio-economic background. By shifting the focus to skills, companies can reduce these biases, offering more opportunities to underrepresented groups. According to SHL, a skills-based model promotes inclusivity by leveling the playing field, making it easier for companies to create a diverse workforce.

The challenges of implementing skills-based hiring

While the benefits of this approach are clear, there are several challenges that companies must navigate when adopting skills-based hiring practices.

  1. Defining clear skills criteria
    One of the main challenges is defining the precise skills required for each role. Companies must shift from focusing on traditional job descriptions to crafting skills-based profiles that clearly outline the necessary competencies.
  2. Effective skills assessment
    Assessing a candidate’s skills is often more complex than verifying their educational background. Companies must rely on practical assessments, such as tests or simulations, to evaluate real-world capabilities. For example, Boeing created an apprenticeship program for cybersecurity roles that doesn’t require a degree but emphasizes hands-on learning and skill development (
    McKinsey & Company) (BCG Global).
  3. Cultural change within organizations
    Shifting from a qualifications-based hiring approach to one focused on skills may require a significant cultural change. Long-standing hiring practices can be difficult to overhaul, and companies must invest in training hiring managers and redesigning recruitment processes to fully embrace skills-based assessments.

How companies can make the shift

  1. Invest in skills assessment tools
    Organizations need reliable tools to accurately assess candidates’ skills. Platforms offering practical evaluations, coding challenges, or case studies can help measure relevant abilities in a fair and transparent manner. As SHL highlights, using data-driven assessments allows companies to objectively evaluate competencies, improving hiring outcomes.
  2. Promote upskilling and internal mobility
    Fostering a culture of continuous learning is essential for the future workforce. Companies that encourage employees to reskill and grow within the organization can fill talent gaps internally. BCG notes that employees hired through skills-based hiring often experience longer tenures and are promoted at rates similar to those hired based on degrees.

How do we see it?

The shift toward skills-based hiring is more than just a trend; it represents a fundamental change in how organizations view talent acquisition. As businesses prioritize practical skills and competencies over traditional qualifications, they can build more dynamic, diverse, and high-performing teams. While there are challenges, including defining clear skills criteria and developing effective assessments, the long-term benefits of this approach make it a valuable strategy for future-proofing the workforce.

This approach is not only more inclusive and adaptable but also positions companies to better meet the demands of a rapidly changing job market. As SHL, BCG, McKinsey&Company and other industry leaders have demonstrated, skills-based hiring is key to unlocking hidden talent and ensuring long-term organizational success (McKinsey & Company).
