Class SpringBeanFacesELResolver

java.lang.Object
  javax.el.ELResolver
      org.springframework.web.jsf.el.SpringBeanFacesELResolver

public class SpringBeanFacesELResolver
extends javax.el.ELResolver

JSF 1.2 ELResolver that delegates to the Spring root WebApplicationContext, resolving name references to Spring-defined beans.

Configure this resolver in your faces-config.xml file as follows:

 <application>
   ...
   <el-resolver>org.springframework.web.jsf.el.DelegatingFacesELResolver</el-resolver>
 </application>

All your JSF expressions can then implicitly refer to the names of Spring-managed service layer beans, for example in property values of JSF-managed beans:

 <managed-bean>
   <managed-bean-name>myJsfManagedBean</managed-bean-name>
   <managed-bean-class>example.MyJsfManagedBean</managed-bean-class>
   <managed-bean-scope>session</managed-bean-scope>
   <managed-property>
     <property-name>mySpringManagedBusinessObject</property-name>
     <value>#{mySpringManagedBusinessObject}</value>
   </managed-property>
 </managed-bean>

with "mySpringManagedBusinessObject" defined as Spring bean in applicationContext.xml:

 <bean id="mySpringManagedBusinessObject" class="example.MySpringManagedBusinessObject">
   ...
 </bean>

getBeanFactory

protected BeanFactory getBeanFactory(javax.el.ELContext elContext)

Retrieve the Spring BeanFactory to delegate bean name resolution to.

The default implementation delegates to getWebApplicationContext. Can be overridden to provide an arbitrary BeanFactory reference to resolve against; usually, this will be a full Spring ApplicationContext.

Parameters:

elContext - the current JSF ELContext

Returns:

the Spring BeanFactory (never null)

See Also:

getWebApplicationContext(javax.el.ELContext)

getWebApplicationContext

protected WebApplicationContext getWebApplicationContext(javax.el.ELContext elContext)

Retrieve the web application context to delegate bean name resolution to.

The default implementation delegates to FacesContextUtils.

Parameters:

elContext - the current JSF ELContext

Returns:

the Spring web application context (never null)

FacesContextUtils.getRequiredWebApplicationContext(javax.faces.context.FacesContext)
