Creating Web applications using the Spring Framework

Who is the course for?
Java software developers eager to acquire programming skills using the Spring framework. As the course is cross-sectional, it can be successfully used by the software developers using framework in their daily work, who wish to systematize their knowledge and/or fill the gaps, explore other areas of the framework more deeply.
Purpose of the course
The aim of the course is to acquire practical programming skills using the Spring framework. The participants will acquire practical knowledge of how to properly prepare a project (XML or Java configuration), how to use dependency injection (IoC container), advanced AOP techniques, how to test applications (individual layers of components as well as the application as a whole), how to integrate the different layers in the Web application or with the use of Web services.
