What is Spring?

[Adrina_g]

Hi, can anyone tell me what exactly the spring is? I have heard that that it is a new framework. But, why this is used. Is it a programming language or any web service? Please, tell me the details of the spring. I don't know what it is, and wanted to know what it is, so please help me to get the information about it. So, if it is helpful, I can learn it.

Same problem here. I also don't have much knowledge about it, but have some knowledge about it, such as it is grate framework for development of Enterprise grade applications. If you want to create a enterprise-ready applications then you can use Spring which is a light-weight framework. It is used for following purpose:

• configure declarative transaction management,
• remote access to your logic using RMI or web services,
• mailing facilities and various options in persisting your data to a database
• Use in modular fashion

Spring is a lightweight container. Spring also contains wrappers that make it easy to use many different services and frameworks. Lightweight containers have the facility that will accept any JavaBean, instead of specific types of components. So, it is more useful.

Features of Spring Framework:

• Lightweight:
• Inversion of control (IOC):
• Aspect oriented (AOP):
• Container:
• MVC Framework:
• Transaction Management:
• JDBC Exception Handling:
• Integration with Hibernate, JDO, and iBATIS
