Web Technology Spring's benefits Offering a lightweight JavaBean container that eliminates the need to write repetitive plumbing code such as lookups Providing an inversion of control framework that allows bean dependencies to be automatically resolved upon object instantiation Allowing cross cutting concerns such as transaction management to be woven into beans as"aspects"rather than becoming the concern of the business object Offering layers of abstraction on top of popular existing technologies such as jdbc and hibernate that ease their use and organize configuration management
