```
public class WebApplicationContextFacesELResolver
extends ELResolver
```
Special JSF ELResolver that exposes the Spring WebApplicationContext instance under a variable named "webApplicationContext".
In contrast to SpringBeanFacesELResolver, this ELResolver variant does not resolve JSF variable names as Spring bean names. It rather exposes Spring's root WebApplicationContext itself under a special name, and is able to resolve "webApplicationContext.mySpringManagedBusinessObject" dereferences to Spring-defined beans in that application context.
Configure this resolver in your faces-config.xml file as follows:
```
 <application>
   ...
   <el-resolver>org.springframework.web.jsf.el.WebApplicationContextFacesELResolver</el-resolver>
 </application>
```
从以下版本开始:

                          Object base,
                          Object property)
                   throws ELException

指定者:: isReadOnly 在类中 ELResolver
抛出:: ELException

getFeatureDescriptors

public Iterator<FeatureDescriptor> getFeatureDescriptors(ELContext elContext,
                                                         Object base)

getWebApplicationContext
```
protected WebApplicationContext getWebApplicationContext(ELContext elContext)
```
Retrieve the WebApplicationContext reference to expose.
The default implementation delegates to FacesContextUtils, returning null if no WebApplicationContext found.
参数:
elContext - the current JSF ELContext
返回:
the Spring web application context
