Spring may be a powerful, lightweight framework used for application development. In broader terms, you'll say that the Spring framework may be a well-defined tool that supports several web applications using Java as a programing language . Before the launching of the framework within the IT Sector, the applications were developed using JEE standards. With these standards, we will deploy an application on any JEE application server. But, it had several problems, including: The code became very complicated because the application progressed. The performance of the system got affected thanks to the heaviness of the applications. The look-up problem of the component. These problems were solved with the introduction of the Spring framework. The Spring framework became prominent within the market thanks to basic Spring framework features, which are its modularity. That is, it are often divided into different modules, each serving their own functionality.

Most Important Features of the Spring Framework

i. Lightweight The Spring Framework is extremely lightweight with reference to its size and functionality. this is often thanks to its POJO implementation, which doesn’t force it to inherit any class or implement any interfaces. ii. Aspect-Oriented Programming (AOP) This is a crucial a part of the Spring Framework. Aspect-Oriented Programming is employed for separating cross-cutting concerns (for example, logging, security, etc.) from the business logic of the appliance . within the coming articles, you'll be learning about this in greater detail. iii. Transaction Management This is wont to unify several transaction management APIs and is employed to coordinate transactions for Java objects. Also, it's not tied to the J2EE environment and is employed with containerless environments. iv. Container The Spring framework designs and manages the lifecycle and configurations of application objects. v. Dependency Injection This feature of the Spring Framework allows you to develop loosely coupled applications. Therefore, the unit testing of those loosely coupled applications becomes easier. This also allows the developer to swap out a number of the modules consistent with its need. vi. Integration With Other Frameworks A great thing about this framework is that it doesn’t attempt to solve the issues that have already been solved. It just tries to integrate them with its framework, which provides an answer to greater problems. for instance , this might include IBATIS, Hibernate, Toplink, etc.
