Please also suggest which one I should start learning first
Well we could spend weeks trying to answer you post completely. So here is a abridged version
1. Struts is a web framework using the MVC2 patter.
2. Hibernate is an Object Relational Mapping api for mapping Java Objects to database tables, and in writing Queries with Java objects
3. Spring is really a big set of "frameworks" and apis, so you can't really say much other than SpringSource is a company.
There is the Spring Framework which is for Dependency Injection and more, there is Spring MVC, which is like Struts, Spring Security, Spring Webflow, Spring Remoting etc.
What you learn first is up to you, what are you most interested in? And the answer isn't what will make you more money, because it won't work that way.
I learned Hibernate first, then I learned Struts, then more recent Spring, but that is just how it ended up working out for me, not by any planning.
