    public abstract class AbstractUrlMethodNameResolver

extends Object
implements MethodNameResolver

Abstract base class for URL-based `MethodNameResolver` implementations.

Provides infrastructure for mapping handlers to URLs and configurable URL lookup. For information on the latter, see the `setAlwaysUseFullPath(boolean)` "alwaysUseFullPath"} and `"urlDecode"` properties.

`void` `setAlwaysUseFullPath(boolean alwaysUseFullPath)` Set if URL lookup should always use full path within current servlet context.

Field Detail

### logger

    protected final Log logger

  Logger available to subclasses

Constructor Detail

### AbstractUrlMethodNameResolver

    public AbstractUrlMethodNameResolver()

Method Detail

### setAlwaysUseFullPath

    public void setAlwaysUseFullPath(boolean alwaysUseFullPath)

  Set if URL lookup should always use full path within current servlet context. Else, the path within the current servlet mapping is used if applicable (i.e. in the case of a ".../*" servlet mapping in web.xml). Default is "false".

  See Also:
    `UrlPathHelper.setAlwaysUseFullPath(boolean)`

### setUrlDecode

    public void setUrlDecode(boolean urlDecode)

  Set if context path and request URI should be URL-decoded. Both are returned undecoded by the Servlet API, in contrast to the servlet path.

  Uses either the request encoding or the default encoding according to the Servlet spec (ISO-8859-1).

  See Also:
    `UrlPathHelper.setUrlDecode(boolean)`

### setUrlPathHelper

    public void setUrlPathHelper(UrlPathHelper urlPathHelper)

  Set the UrlPathHelper to use for resolution of lookup paths.

  Use this to override the default UrlPathHelper with a custom subclass, or to share common UrlPathHelper settings across multiple MethodNameResolvers and HandlerMappings.

  See Also:
    `AbstractUrlHandlerMapping.setUrlPathHelper(org.springframework.web.util.UrlPathHelper)`

### getHandlerMethodName

    public final String getHandlerMethodName(HttpServletRequest request)
                                      throws NoSuchRequestHandlingMethodException

  Retrieves the URL path to use for lookup and delegates to `getHandlerMethodNameForUrlPath`. Converts `null` values to NoSuchRequestHandlingMethodExceptions.

  Specified by:
    `getHandlerMethodName` in interface `MethodNameResolver`
  Parameters:
    `request` - current HTTP request
  Returns:
    a method name that can handle this request. Never returns `null`; throws exception if not resolvable.
  Throws:
    `NoSuchRequestHandlingMethodException` - if no handler method can be found for the given request
  See Also:
    `getHandlerMethodNameForUrlPath(java.lang.String)`

### getHandlerMethodNameForUrlPath

    protected abstract String getHandlerMethodNameForUrlPath(String urlPath)

  Return a method name that can handle this request, based on the given lookup path. Called by `getHandlerMethodName`.

  Parameters:
    `urlPath` - the URL path to use for lookup, according to the settings in this class
  Returns:
    a method name that can handle this request. Should return null if no matching method found.
  See Also:
    `getHandlerMethodName(javax.servlet.http.HttpServletRequest)`, `setAlwaysUseFullPath(boolean)`, `setUrlDecode(boolean)`
