What is Spring

This spring tutorial provides in-depth concepts of Spring Framework with simplified examples. It was developed by Rod Johnson in 2003. Spring framework makes the easy development of JavaEE application.
  • Spring can refer to various things, depending on the context. Here are a few common meanings:


  • Spring is one of the four seasons in many parts of the world, typically occurring between winter and summer. It is known for milder temperatures, budding flowers, and longer daylight hours.

2.Coil or Wire:

  • In mechanical and engineering contexts, a spring can refer to a coiled or wound piece of metal (often steel) that can store mechanical energy when compressed or stretched and then release it. Springs are used in various applications, such as in car suspension systems, watches, and mattresses.

3.Spring Framework:

  • In the world of software development, Spring refers to the Spring Framework, which is an open-source framework for building Java-based enterprise applications. It provides a comprehensive infrastructure for developing Java applications, making it easier to manage components, handle data access, and implement various enterprise features.
  • The Spring framework comprises several modules such as IOC, AOP, DAO, Context, ORM, WEB MVC etc. We will learn these modules in next page. Let’s understand the IOC and Dependency Injection first.

4.Water Source:

  • A spring can also be a natural source of water that flows to the surface from underground. Springs are often found in hilly or mountainous areas and can provide a reliable source of freshwater.
  • The meaning of “spring” can vary widely depending on the context in which it is used. If you have a specific context in mind, please provide more details, and I can offer a more precise explanation.

Advantages of Spring Framework

  • The Spring Framework offers several advantages in the world of Java-based enterprise application development. Here are some of the key advantages:


  • Spring follows the principle of modularity, allowing developers to use only the parts of the framework they need. This modularity makes it highly customizable and adaptable to various project requirements.

Dependency Injection (DI):

  • Spring promotes the use of dependency injection, which simplifies the management and injection of components and their dependencies. This enhances code readability, testability, and maintainability by reducing tight coupling between classes.

Aspect-Oriented Programming (AOP):

  • Spring provides support for AOP, which allows developers to modularize cross-cutting concerns, such as logging, security, and transaction management. This promotes cleaner and more maintainable code.

Transaction Management:

  • Spring offers robust and flexible transaction management capabilities. It can manage both programmatic and declarative transactions, making it easier to work with databases and other resources reliably.

Enterprise Integration:

  • Spring provides various tools and libraries for integrating with enterprise technologies, such as JMS (Java Messaging Service), JTA (Java Transaction API), and JPA (Java Persistence API). This simplifies the development of complex enterprise applications.


  • Spring Security is a part of the Spring Framework that simplifies the implementation of security features in web applications, including authentication, authorization, and protection against common security threats.
  • Overall, the Spring Framework is widely used in enterprise application development due to its versatility, ease of use, and the advantages it provides in terms of code quality, maintainability, and scalability.

Open Source and Active Community:

  • Spring is open-source and has a large and active community of developers and contributors. This ensures that the framework is continually improved, well-documented, and well-supported.

Simplified Java EE Development:

  • Spring simplifies Java EE (Enterprise Edition) development by providing abstractions and simplifications for common Java EE tasks. This reduces the complexity and verbosity of Java EE-based applications.
