This course enables the experienced Java developer to use the Spring application framework to manage objects in a lightweight, inversion-of-control container, and to build sophisticated web applications using the model/view/controller or MVC framework.

Spring's core module gives the developer declarative control over object creation and assembly; this is useful for any tier of any Java application, so we study it in some depth to begin the course. Then students build web applications that use Spring MVC to organize their designs into coherent request/response cycles. They use Spring command objects to manage HTML forms and their data, and connect these to the validation framework. We connect our applications to persistent stores and study the DAO and ORM modules, to better understand JDBC and JPA persistence models and declarative transaction control. The course concludes with a chapter on Spring's testing framework, including the mock-MVC utilities for web controllers.

Learning Objectives

  • Understand the scope, purpose, and architecture of Spring
  • Use Spring application contexts to declare application components, rather than hard-coding their states and lifecycles
  • Use dependency injection to further control object relationships from outside the Java code base
  • Use annotations to take advantage of Spring post-processors for automated bean instantiation and wiring
  • Build a web application as a Spring DispatcherServlet and associated application context
  • Use Spring MVC annotations to develop web controllers, mapping request URLs and other criteria to Java methods and binding request data to method parameters
  • Build and manage HTML forms with Spring command objects and custom tags
  • Customize input binding, validation, and error handling
  • Use Spring interceptors to implement horizontal features in the web application
  • Connect business objects to persistent stores using Spring's DAO and ORM modules
  • Simplify JDBC code using Spring templates
  • Integrate JPA entities and DAOs into Spring applications
  • Control transactions using Spring, either programmatically or declaratively
  • Develop effective unit tests using Spring's test framework and the MockMvc environment for web controllers
