I will be getting some assignments from one of my Senior Members of my Company. He told me to read SPRING Framework and on next Monday he'll provide me some small assignments.Please suggest me some important topics, so that I can do it within 2 days.. so that whatever he is going to explain me goes smooth....
Spring has many sub- projects and 2 days is not a reasonable amount of time to even scratch the surface. It is one of those things you are going to have to learn as you go once you get your small assignments. You can get acquainted with the various spring projects here:
On that same link you will find the reference documentation which is very good and also a link to the spring-samples repository. After that google around for 'Spring tutorials' and try to make sure the tutorials are current and are using at least Spring 3.
