No need to reinvent the wheel is one of the most important benefits that developers can leverage from the Spring Framework. It facilitates the practical use of the well-known technologies, ORM frameworks, logging frameworks, JEE, JDK timers, Quartz, and so on. So, developers don't have to learn any new technologies or frameworks.

It facilitates good programming practices, such as programming using interfaces instead of classes. Spring enables developers to develop enterprise applications using POJO and Plain Old Java Interface (POJI) model programming.
