Struts is developed with a Front Controller and dispatcher
pattern. Where in all the requests go to the ActionServlet
thereby routed to the module specific Request Processor
which then loads the associated Form Beans, perform
validations and then handovers the control to the
appropriate Action class with the help of the action mapping
specified in Struts-config.xml file. On the other hand,
spring does not route the request in a specific way like
this, rather it allows to you to design in your own way
however in allowing to exploit the power of framework, it
allows you to use the Aspect Oriented Programming and
Inversion of Control in a great way with great deal of
declarative programming with the XML. Commons framework can
be integrated to leverage the validation in spring framework
too. Morethan this, it provides all features like JDBC
connectivity, OR Mapping etc., just to develop & run your
applications on the top of this.
