JavaSpring MVC Web Applications Training

Goals

• Understand the scope, purpose, and architecture of Spring
• Use Spring’s bean factories and 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
• Create validators for business objects, and associate them for application-level and unit-testing uses
• 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
• 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
• Declare and enforce transaction requirements using Spring
