Queries regarding getting a job as a software developer

I'm Computer Science Fresher and is looking for a good job in software devlopment. I know topics like Core Java, C++, data structures, SQL, etc. I have following queries -

1) Should I learn advanced topics like JEE, Spring, Hibernate, etc. before getting a job, or else, are these topics covered by companies in training period for freshers ? I know this aspect will differ from company to company but I want to know general trend about training in companies. Do most of the companies provide training to freshers ?

2) Does topics like mentioned above (JEE, Spring, Hibernate, etc.) are worth learning before getting a job at fresher stage or can be learned after getting a job by experiance, even when there is no training ?

3) Do such topics can be learned indepedently if I had a basic knowledge like core java or I need to go a training institute to learn them ?
