Getting started with Spring Web Flow 2.0

To implement the shopping cart process for the sample application, follow these steps:

Import a related class library under the/web-inf/lib directory

Add a configuration with Spring Web flow integration in Webmvc-config.xml

Add a configuration file for Spring Web flow webflow-config.xml

Add a flow definition file Shopping.xml

Add three JSP pages

Modify Index.jsp

Import a related class library under the/web-inf/lib directory

Import the following jar packages into the/web-inf/lib directory:

Org.springframework.webflow-2.0.2.release.jar

Org.springframework.js-2.0.2.release.jar

Org.springframework.binding-2.0.2.release.jar

Jboss-el.jar

Adding a configuration to the Webmvc-config.xml

The Spring Web MVC-related configuration was previously analyzed, and the complete configuration is shown in Listing 13:
