Spring Framework

Spring is a J2EE framework and aims to simplify J2EE development

  • Lightweight – A non invasive container that can assemble set of loosely coupled POJOs. This allows software components to be tested in isolation
  • Abstract Transaction Manager – Allows for pluggable transaction managers, not tied to J2EE environments
  • JDBC abstratcion layer – meaningfull exception hierarchy (no need to extract vendor codes from SQLException) simplified error handling.
    Integrartes with Toplink, Hibernate, JDO and iBATIS SQL maps
  • AOP functionality – can AOP any object and add aspects such as declarative transaction management. Transaction management can be done without EJB or JTA
  • A flexible MVC architecture – Can work with Struts, WebWork or Tapestry and accomodates multiple view techonlogies like JSP, Velocity, Tiles, iText and POI
Spring uses a setter based dependancy injection pattern (Inversion of Control)

One should be careful of not overdoing this approach as it can make your code a lot more verbose.
