Building a sample Spring MVC application. (2 h)
  4. Inversion of Control (IoC) and Dependency Injection (DI) in Spring (Advanced) – Bean scopes – singleton, request, session, application, websocket, and custom scopes. Web configuration. Scoped beans as dependencies – <aop:scoped-proxy>. Lifecycle callbacks – initialization, destruction, @PostConstruct, @PreDestroy. ApplicationContextAware, BeanNameAware interfaces. Using Spring resource injection annotations – @Autowired, @Component, @Scope, @Value, @Required, @Qualifier, @Lazy, @Primary. Using JSR 330 standard annotations – @Resource, @Inject, @Named, @ManagedBean, @Qualifier, @Alternative. Environment and profiles, @PropertySource. I18N using MessageSource.

Презентациите, демонстрациите и hands-on упражненията се провеждат паралелно с цел незабавно затвърждаване на концепциите чрез практика.

Участниците ще се научат да разработват, внедряват и тестват готови за продукция и сигурни уеб приложения и услуги със Spring Boot, Hibernate, Spring MVC, и REST. Обучението се осъществява в малки групи – до 10 човека. По време на тренинга ще можем да дискутираме и допълнителни въпросиима възможност за дискутиране на допълнителни въпроси от интерес за участниците.
