Java is a very powerful open source programming language. Spring is a framework of Java to develop robust Java applications very easily and rapidly. Using core features of this framework any java application can be developed but because it consists many helpful extensions to develop web apps it is mainly used for developing web applications. Hibernate is a java framework for mapping an object-oriented domain model to a relational database. Knowledge of Spring along with Hibernate provides greater job opportunities. Spring/Hibernate has produced around 10,000 jobs all over India in present month. Spring professionals can earn up to 10 lakhs and more after more experience and higher positions.
Pros
Due to Spring's lose coupling features applications can be easily modified. This lose coupling feature also helps in reducing excess memory consumption. Spring helps in reducing development time of application when compared to other conventional ways. One of major pros of Hibernate is that it has its own query language which is Called Hibernate Query Language(HQL). HQL is database independent and has its own database independent commands, so if there is a need to change database, then it will create no hassle in application because application has coding written for hibernate in HQL and further interaction with database will be taken care by Hibernate. As a result of this approach Hibernate can be used to connect with multiple databases too.
Cons
For cons of Spring we can say it is considered rather complex with tons of coding in XML and has a longer learning curve. As for cons of Hibernate it is has been seen that it needs expertise before anyone can really reap its benefits. One has to be proficient in knowledge of ORM concepts, mappings and relations, understanding of how the Session works, with more advanced concepts like lazy-loading, fetching strategies etc.
