Spring Framework FAQs

What is the Spring framework?

Java is more than a language—it’s a sprawling package of tools that make this language able to do a lot on the enterprise-level. When you choose Java for an application, you’re not just choosing the programming language; you’re adopting an entire ecosystem comprising Core Java, various IDEs, libraries, the Java Virtual Machine (JVM), and frameworks like Struts, Stripes, and Swing. 

The Java Enterprise Edition (EE) platform in particular is tailored specifically to enterprise clients who need certain functionalities baked in. However, J2EE applications come with some drawbacks and flaws commonly associated with Java: mainly, bulky, excessive, and duplicate code. J2EE applications can also be difficult to unit test.

That’s where the Spring Framework comes in, simplifying certain functionalities with built-in patterns and practices. Note: As with all frameworks, Spring is not going to be a silver bullet and it’s always possible to overcomplicate code, but it does offer some great benefits. It’s specifically known for its “dependency injection” and inversion control capabilities—object-oriented programming (OOP) practices that can be handy for eliminating duplicate methods and for unit testing.

Spring Framework is an application framework that provides inversion control features for the Java Platform. Spring lets you pick and choose from numerous packages like Spring Cloud, Spring Mobile, Spring Data, and an excellent solution for built-in authentication and authorization measures, Spring Security.

Why hire Spring framework specialists?

If you are working with the Spring Framework or Java Platform, consider enlisting the help of a Spring Framework developer or programmer. These technicians come with experience applicable to Spring Framework and are highly qualified computer programmers with demonstrable skills working with the Java Platform. 

Developers can help you generate and finalize applications built on the Spring Framework, ensuring you are presenting the best version of that application, whereas a skilled programmer can collaborate with you to lay down the brick-and-mortar functions of a new software program.
