Class AutowiringRequestProcessor

    java.lang.Object
      org.apache.struts.action.RequestProcessor
          org.springframework.web.struts.AutowiringRequestProcessor

Deprecated. as of Spring 3.0

    @Deprecated
    public class AutowiringRequestProcessor

extends org.apache.struts.action.RequestProcessor

Subclass of Struts's default RequestProcessor that autowires Struts Actions with Spring beans defined in ContextLoaderPlugIn's WebApplicationContext or - in case of general service layer beans - in the root WebApplicationContext.

In the Struts config file, you simply continue to specify the original Action class. The instance created for that class will automatically get wired with matching service layer beans, that is, bean property setters will automatically be called if a service layer bean matches the property.

     <action path="/login" type="myapp.MyAction"/>

There are two autowire modes available: "byType" and "byName". The default is "byType", matching service layer beans with the Action's bean property argument types. This behavior can be changed through specifying an "autowire" init-param for the Struts ActionServlet with the value "byName", which will match service layer bean names with the Action's bean property names.

Dependency checking is turned off by default: If no matching service layer bean can be found, the setter in question will simply not get invoked. To enforce matching service layer beans, consider specify the "dependencyCheck" init-param for the Struts ActionServlet with the value "true".

If you also need the Tiles setup functionality of the original TilesRequestProcessor, use AutowiringTilesRequestProcessor. As there's just a single central class to customize in Struts, we have to provide another subclass here, covering both the Tiles and the Spring delegation aspect.

The default implementation delegates to the DelegatingActionUtils class as fas as possible, to reuse as much code as possible despite the need to provide two RequestProcessor subclasses. If you need to subclass yet another RequestProcessor, take this class as a template, delegating to DelegatingActionUtils just like it.

  Deprecated.

Method Detail

### init

    public void init(org.apache.struts.action.ActionServlet actionServlet,
                     org.apache.struts.config.ModuleConfig moduleConfig)
              throws javax.servlet.ServletException

  Deprecated.
  Overrides:
    `init` in class `org.apache.struts.action.RequestProcessor`
  Throws:
    `javax.servlet.ServletException`

### initWebApplicationContext

    protected WebApplicationContext initWebApplicationContext(org.apache.struts.action.ActionServlet actionServlet,
                                                              org.apache.struts.config.ModuleConfig moduleConfig)
                                                       throws java.lang.IllegalStateException

  Deprecated.
  Fetch ContextLoaderPlugIn's WebApplicationContext from the ServletContext, falling back to the root WebApplicationContext. This context is supposed to contain the service layer beans to wire the Struts Actions with.

  Parameters:
    `actionServlet` - the associated ActionServlet
    `moduleConfig` - the associated ModuleConfig
  Returns:
    the WebApplicationContext
  Throws:
    `java.lang.IllegalStateException` - if no WebApplicationContext could be found

### initAutowireMode

    protected int initAutowireMode(org.apache.struts.action.ActionServlet actionServlet,

  Deprecated.
  Determine the autowire mode to use for wiring Struts Actions.

  The default implementation checks the "autowire" init-param of the Struts ActionServlet, falling back to "AUTOWIRE_BY_TYPE" as default.

  Parameters:
    `actionServlet` - the associated ActionServlet
    `moduleConfig` - the associated ModuleConfig
  Returns:
    the autowire mode to use
