What is Application Context in Spring?
| A bean factory is fine to simple applications, but to take advantage of the full power of the Spring framework, you may want to move up to Springs more advanced container, the application context.

Constructor Injection: Constructor-based DI is realized by invoking a constructor with a number of arguments, each representing a collaborator. |
