## org.springframework.web.struts
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

  Juergen Hoeller

Field Summary
`static String` | `AUTOWIRE_BY_NAME` Deprecated. Value of the autowire init-param that indicates autowiring by name: "byName"
`static String` | `AUTOWIRE_BY_TYPE` Deprecated. Value of the autowire init-param that indicates autowiring by type: "byType"
`static String` | `PARAM_AUTOWIRE` Deprecated. The name of the autowire init-param specified on the Struts ActionServlet: "spring.autowire"
`static String` | `PARAM_DEPENDENCY_CHECK` Deprecated. The name of the dependency check init-param specified on the Struts ActionServlet: "spring.dependencyCheck"

Method Summary
`static String` | `determineActionBeanName(ActionMapping mapping)` Deprecated. Default implementation of Action bean determination, taking the mapping path and prepending the module prefix, if any.
`static WebApplicationContext` | `findRequiredWebApplicationContext(ActionServlet actionServlet, ModuleConfig moduleConfig)` Deprecated. Find most specific context available: check ContextLoaderPlugIn's WebApplicationContext first, fall back to root WebApplicationContext else.
`static int` | `getAutowireMode(ActionServlet actionServlet)` Deprecated. Determine the autowire mode from the "autowire" init-param of the Struts ActionServlet, falling back to "AUTOWIRE_BY_TYPE" as default.
`static boolean` | `getDependencyCheck(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(ActionServlet actionServlet, ModuleConfig moduleConfig)` Deprecated. Fetch ContextLoaderPlugIn's WebApplicationContext from the ServletContext.
`static WebApplicationContext` | `getWebApplicationContext(ActionServlet actionServlet, ModuleConfig moduleConfig)` Deprecated. Fetch ContextLoaderPlugIn's WebApplicationContext from the ServletContext.
