Can anyone explain me the concept of inversion of control in spring pls
The Spring manuals explain that in great detail so you're supposed to read it. The
general idea of IoC or DI (Dependency Injection) is a POJO (Plain Old Java Object)
that does what it has to do given just interfaces. The IoC mechanism supplies
implementations of those interfaces and 'injects' them into the POJO; all you
have to do is define what implementation needs to be injected in a declarative
manner (outside the actual code), usually using xml files.
kind regards,
