Why SpringFramework?

This topic can be slightly different answer when discuss with different context.

#. Using Spring in light weighted model.

• - MVC tier + DAO + Annemic Domain Model - MVC tier + POJO and DDD style design

#. Using Spring in multi-tier architecture

• - Using SpringFramework to replace EJB (session bean) model

#. Bean container provide DI, bean management, with following features:

• - AOP - Injection preprocessing (custom annotation behavior) - Bean can be singleton, prototype, and customly defined scope
  • Compared with purely Session Bean model, this allow more flexible design
  - Configurability

#. Promoting 'Design to Interface'

• - General (non-spring specific) design / engineering technique - Promote testability, loose coupling - Using Spring will promote this mentality.

#. Reduce coding

• - SpringFramework provide tons of utilities class - JDBCTemplate, HibernateTemplate, JMSTemplate - Remoting support - Quartz scheduler integration - ThreadQueue implementation

#. The maturity and propularity of Spring brings additional advantages

• - Different framework, library provide Spring integration out of the box

  • Example: AcegiSecurity, ActiveMQ

#. Other commonly raised adv:

• - Built-in integration for Web Services / various remoting technology - Built-in integration for JMX, Portlet
