# Spring Framework Workshop
These are my notes on the great course [Spring Core - Learn Spring Framework 4 and Spring Boot on Udemy](https://www.udemy.com/spring-core). This repository does not include everything mentioned in the course, so go ahead and have a look at the other great courses from the [springframeworkguru John Thompson](https://springframework.guru)!
Also, the most part of this code is also published in [Johns repository for the workshop](https://github.com/springframeworkguru/spring-core-spring-mvc).
## History of Spring
- 1998 EJB Specification, aimed for scalability, security, high availability, by Sun. Multiple problems in usage, for example tightly coupled to application server
- 2004 first release Spring as OpenSource (Spring Source, today Pivotal). Better testability because parts of implementation easily interchangeable by mocks or other implementations
- today: Spring greatest market share. However, EJB also developed further. However, a lot of debate on how EJB will be developed in the future.
## Spring Core
- = central part of Spring framework
- Spring beans = simple Java Objects (POJO)
- by design, Spring Beans are meant to be simple, not overly complex objects (Single Responsibility Principle)
- Dependency Injection (DI)
- = dependent objects are injected into class at hand
- first largely absent in original EJB specification
- Inversion of Control (IoC)
- Spring Framework is in control and manages software components and injection of components into dependent objects
- DI + IoC allow for loosely coupled classes: when testing a web controller, inject mock database or mock service instead of the real classes
- Spring Context = "what all brings together". Knows beans and configuration and injects objects accordingly
- a lot of projects around Spring Core, for example Data, MVC, Security, Boot
