Review: What is Spring?
• Spring is a framework with many modules
– To simplify many different Java EE tasks

• Core module: dependency injection
– Lets you define an XML file that specifies which beans
you define an XML file thatspecifies which beans
are created and what their properties are
• Simplifies OOP by promoting loose coupling between
classes Also called Inversion of Control (IoC)
classes. Also called “Inversion of Control” (IoC)

– This is the module that we will use with JSF
• This tutorial assumes you are already familiar with Spring
dependency injection in desktop Java apps

• Many other modules
– AOP, security, JDBC templates, etc.

• Although most of these are not contradictory to the use of
JSF, dependency injection is by far the most sought-after
Spring feature for JSF apps

Why Use Spring?
Why Use Spring?
• Issue
– JSF already supports dependency injection via the
managed-property element of faces-config.xml• So why use Spring to do what JSF already does?
why use Spring to do what JSF already does?

• Reasons
– You might already have beans set up with Spring from
other applications
• And you would like to use them without adding new code

– Spring is more powerful
is more powerful
• Spring supports more and better dependency injection
features than does faces-config.xml.
• But, beforeintroducing Spring, make sure your JSF app
before introducing Spring make sure your JSF app
will significantly benefit from these features

Why Use New Approach?
Why Use New Approach?
• Issue
– Normal Spring already supports ways to access beans.
• So why add a new way for JSF?

• Reasons
– You need to access bean definitions from many places
