  • @martinmiloshev241
    @martinmiloshev241 2 года назад +6

    7:18 so basically the Spring Container is something similar to the String Pool in the JVM in a static way.
    Just before running your app, Spring will initialize and collect all its beans and will store them into it.
    Whenever you want it -> you bring it out from the box.
    btw, nice explanation, Navin!

  • @chinchi4293
    @chinchi4293 Год назад

    Very well explained. Searched for several videos but found this was one of the best. It is exactly how do you learn by doing mistakes or boiler plate code and see the advantages of the spring concepts. Most of the videos do not consider that approach at all why some concepts are needed. You are a good teacher.

    But today i got the whole background of it.
    Thanks to Alien( Reddy sir) for these magical explanations.
