Description
Spring is a lightweight, open source framework first released in 2003. Now Spring is a popular open source project, that covers various aspects of both JavaEE and JavaSE development. The Spring Framework is best known as a source extension (features), necessary for the efficient development of complex business applications outside software heavyweight models.The Spring Framework can be viewed as a collection of smaller frameworks, most of which can operate independently of each other. However, they provide more functionality when used jointly. Abstract classes, factories and beans are designed so that the programmer can concentrate on writing business logic only.
This course will give participants information related to how the Spring Framework works. They will learn about the basic modules of the framework and options for their use as well as how to use the Spring framework in conjunction with other technologies.
