Class AbstractUrlMethodNameResolver

java.lang.Object

org.springframework.web.servlet.mvc.multiaction.AbstractUrlMethodNameResolver

All Implemented Interfaces:

MethodNameResolver

Direct Known Subclasses:

InternalPathMethodNameResolver, PropertiesMethodNameResolver

public abstract class AbstractUrlMethodNameResolver
extends java.lang.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.

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:

AbstractHandlerMapping.setUrlPathHelper(org.springframework.web.util.UrlPathHelper)

getHandlerMethodName

public final java.lang.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 java.lang.String getHandlerMethodNameForUrlPath(java.lang.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.
