The Spring Framework is an open source application framework and inversion of control container for the Java platform. It was originally created as an alternative to Enterprise JavaBeans (EJB) and aims to simplify enterprise Java development. The Spring Framework includes modules for core functionality, aspects, model-view-controller (MVC), and more. It utilizes dependency injection and inversion of control to decouple components. Spring is widely adopted and supported by a large community.

23. Core Principles Inversion of Control Dependency Injection Standards compliance a secondary goal

24. Test first

25. Avoid coupling to Spring framework

26. Cross cutting concerns through simplified AOP

27. Convention over Configuration

28. Examples We're using Spring in SLI every day! Here's how: API Security, IoC container, Test Ingestion IoC container, Test DAL Spring Data, IoC Container, Test Databrowser Spring MVC, IoC, Test

29. Inversion of Control (IoC) Component scanning Bean stereotypes

30. Auto-wiring ApplicationContextAware

31. @PostConstruct Java: @Service public class SchoolRepositoryService implements SchoolService { @Autowired SchoolRepository schoolRepository; XML: <context:component-scan base-package=&quot;net.wgen&quot; />

32. <context:annotation-config />

33. Spring Data Repository pattern in the DAL abstracts implementation of OR/M from service and ingestion layers

34. Allows for swap-out of persistence technology if needed

35. Eliminates boilerplate code that exists in many JPA / Hibernate projects by proxying DAOs. db.xml: <jpa:repositories base-package=&quot;net.wgen.sli.repository&quot; />

36. Security API module has in-memory authentication example in securityContext.xml

37. Leverages the security namespace

38. More usage of Spring Security's permission evaluation coming in Sprint 3

39. Spring FAQ Q: Can Spring help me decouple infrastructure concerns from my business logic? A: Yes, that's the core use case around using the IoC container Q: Can Spring help me eliminate repetitive code? A: Runtime proxying, dependency injection, and AOP are solutions Q: Can Spring help me isolate layers during unit test time? A: Yes, use different application contexts that mock out external dependencies Q: Can Spring help me with my Christmas shopping or cooking my potluck dish? A: No, sorry.
