Class SpringBeanFacesELResolver

java.lang.Object

javax.el.ELResolver

org.springframework.beans.factory.access.el.SpringBeanELResolver

org.springframework.web.jsf.el.SpringBeanFacesELResolver

public class SpringBeanFacesELResolver
extends org.springframework.beans.factory.access.el.SpringBeanELResolver

JSF 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.SpringBeanFacesELResolver</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>

Method Detail

getBeanFactory

protected org.springframework.beans.factory.BeanFactory getBeanFactory(ELContext elContext)

This implementation delegates to getWebApplicationContext(javax.el.ELContext). Can be overridden to provide an arbitrary BeanFactory reference to resolve against; usually, this will be a full Spring ApplicationContext.

Specified by:

getBeanFactory in class org.springframework.beans.factory.access.el.SpringBeanELResolver

Parameters:

elContext - the current JSF ELContext

Returns:

the Spring BeanFactory (never null)

getWebApplicationContext

protected WebApplicationContext getWebApplicationContext(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)
