Spring Book – Chapter 13 – Spring and JSF Integration

JSF and Spring

Coming straight to integration approaches, there are two approaches possible as below:

  • Spring-centric integration
  • JSF-centric integration

Spring-centric integration

With latest release of Spring (later than Spring version 2.x), Spring Framework has a capability of handling JSF backing beans in its IoC container avoiding JSF IoC container in all aspects and making using of strong Spring IoC for managing beans in a JSF application. By using this you can completely avoid putting the bean declaration in the faces-config.xml file and use the Spring configuration file instead. The following steps needs to be done to achieve this Spring-centric approach:

  • Declare the DelegatingVariableReslver in the faces-config.xml file as shown in Listing 13-1 below.

Listing 13-1. Declaring DelegatingVariableResolver in faces-config.xml file

  • Declare your backing bean as well as Spring bean in the Spring configuration file as shown in Listing 13-2 below.

Listing 13-2. Declaring backing bean and Spring bean in Spring configuration file

  • Declaring appropriate listeners in the web application context file web.xml as shown in Listing 13-3 below.

Listing 13-3. Configuring listeners in the web.xml file of your JSF application

Pictorially this Spring-centric approach can be depicted as shown in Figure 13-5 below.

This approach is referred from a blog entry written in the following URL which seemed very logical; http://cagataycivici.wordpress.com/2007/09/10/using-spring-to-manage-jsf-beans/. You can have a complete working sample of this approach in this blog entry.
