Class SpringBeanFacesELResolver

java.lang.Object

jakarta.el.ELResolver

org.springframework.web.jsf.el.SpringBeanFacesELResolver

public class SpringBeanFacesELResolver
extends ELResolver

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>
