At the Core of Spring Framework, Spring IoC (Inversion of Control) is implemented using the Dependency Injection design pattern. The Spring IoC Container creates, configures and connects the objects (which are called Beans), then manage their life cycle.
This tutorial introduce principle of Spring IoC and a simple example using Containers to you.

The BeanPostProcessor interface helps us provide our own methods before the initialization of beans and likewise after the initialization of the bean.
BeanPostProcessor are common for all beans in the container where it is defined, so it is different from @PostConstruct, InitializingBean and custom init method which are defined on the bean itself.

Spring Bean Life Cycle is very important because in many applications, we want to create some operations before initializing a Bean or make some operations before bean’s destruction.
This tutorial introduce four ways to control life cycle events of a Bean.

Spring Bean Scopes helps you control the scope of the objects which are created from bean definition. This approach is wonderful because you can choose the scope by configuring bean instead of working at Java class level.
The Spring Framework supports 7 scopes, but this tutorial introduces you 2 of them: singleton scope and prototype scope. The others will be discussed in next article.
