Class DelegatingActionUtils

java.lang.Object

org.springframework.web.struts.DelegatingActionUtils

Deprecated.

as of Spring 3.0

@Deprecated
public abstract class DelegatingActionUtils
extends Object

Common methods for letting Struts Actions work with a Spring WebApplicationContext.

As everything in Struts is based on concrete inheritance, we have to provide an Action subclass (DelegatingActionProxy) and two RequestProcessor subclasses (DelegatingRequestProcessor and DelegatingTilesRequestProcessor). The only way to share common functionality is a utility class like this one.

Since:

1.0.2

Modifier and Type	Method and Description
static String	determineActionBeanName(org.apache.struts.action.ActionMapping mapping) Deprecated. Default implementation of Action bean determination, taking the mapping path and prepending the module prefix, if any.
static WebApplicationContext	findRequiredWebApplicationContext(org.apache.struts.action.ActionServlet actionServlet, org.apache.struts.config.ModuleConfig moduleConfig) Deprecated. Find most specific context available: check ContextLoaderPlugIn's WebApplicationContext first, fall back to root WebApplicationContext else.

static boolean	getDependencyCheck(org.apache.struts.action.ActionServlet actionServlet) Deprecated. Determine the dependency check to use from the "dependencyCheck" init-param of the Struts ActionServlet, falling back to no dependency check as default.
static WebApplicationContext	getRequiredWebApplicationContext(org.apache.struts.action.ActionServlet actionServlet, org.apache.struts.config.ModuleConfig moduleConfig) Deprecated. Fetch ContextLoaderPlugIn's WebApplicationContext from the ServletContext.
