Demo project with custom Spring framework implementations.

The main idea what Spring framework exactly does is the following snippet:

@SneakyThrows
public <T> T createObject(Class<T> implClass) {

    T t = create(implClass);

    configure(t);

    invokeInit(implClass, t);

    t = wrapWithProxyIfNeeded(implClass, t);

    return t;
}

Literally it is:

• creates new instance
• configure it
• call init logic for object (2 Phase constructor)
• wrap with proxy when it is needed
• return bean to the container
