Spring has a lightweight structure or framework. It tends to be considered a system of structures since it offers help to different systems like Struts, Hibernate, Tapestry, EJB, JSF, etc. In a more extensive sense, the system can be characterized as a design where we discover the arrangement of the different specialized issues. The Spring framework involves various modules, for example, IOC, AOP, DAO, Context, ORM, WEB MVC, and so forth.

Spring has a lightweight structure or framework. It tends to be considered a system of structures since it offers help to different systems like Struts, Hibernate, Tapestry, EJB, JSF, etc. In a more extensive sense, the system can be characterized as a design where we discover the arrangement of the different specialized issues. The Spring framework involves various modules, for example, IOC, AOP, DAO, Context, ORM, WEB MVC, and so forth.

• Lightweight 

Spring is lightweight concerning measure and transparency. The fundamental rendition of the spring system is around 1MB. What's more, the handling overhead is likewise entirely negligible. 

• Inversion of control (IOC) 

The fundamental idea of the Dependency Injection or Inversion of Control is that developers don't have to make the articles, rather depict how they ought to be made. There is no compelling reason to straightforwardly interface your parts and administrations together in the program, rather portray which administrations are required by what parts in an arrangement record/XML document. The Spring IOC holder is then answerable for restricting everything up. 

• Aspect-oriented programming (AOP) 

Spring framework upholds Aspect-oriented programming. AOP alludes to the programming worldview, which disconnects auxiliary or supporting capacities from the entire program's business rationale. AOP is a promising innovation for isolating crosscutting concerns, something typically difficult to do in object-oriented programming. The application's measured quality is expanded in that manner, and its upkeep turns out to be fundamentally simpler. 

• Container

Spring contains and deals with the existence cycle and setup of application objects.

• MVC Framework 

Spring accompanies the MVC web application system based on core Spring functionality. This system is exceptionally configurable, employing methodology interfaces, and obliges numerous view innovations like JSP, Velocity, Tiles, iText, and POI. However, different structures can be handily utilized as opposed to Spring MVC Framework. 

• Transaction Management

Spring framework gives a conventional reflection layer to exchange the board. This permits the engineer to add the pluggable exchange supervisors and make it simple to divide exchanges without managing low-level issues. Spring's transaction support isn't attached to J2EE conditions, and it tends to be likewise utilized in compartment-less conditions. 

• JDBC Exception Handling 

The JDBC abstraction layer of the Spring offers a significant exception hierarchy, which improves the error handling technique. Mix with Hibernate, JDO, and iBATIS: Spring furnishes the best Integration administrations with Hibernate, JDO, and iBATIS
