Spring Framework is a backend framework for enterprise application development written in Java. Because Java is platform-independent, applications written in Spring Framework can be deployed to any platform. This also makes it possible for developers to focus on creating application logic while Spring Framework handles all the interaction with the operating system. Core parts of Spring Framework include the IoC container, which handles the configuration of application objects; the Data access framework, which allows developers to write simple code to store and retrieve data that is stored in databases; and Spring MVC framework, which gives developers tools to structure applications according to the Model-View-Controller pattern. These and other parts of Spring work together and make building applications for enterprise quicker, easier, and more trouble-free.

There are many careers available in enterprise development for programmers that know Spring Framework. In fact, a large majority of Java development jobs require knowledge of Spring. The type of work you do with Spring Framework can vary since it is so flexible. A Spring Java developer designs and builds large-scale applications for enterprises that have high availability and performance. A Spring application developer specializes in creating client applications that run on workstations and laptops. A Java Springboot developer develops web applications and microservices with Spring Framework. A Java backend developer uses Spring Framework to create the server-side code of web applications. A Java e-commerce developer uses Spring Framework for handling customer orders and processing payments.
