public abstract class AbstractUrlHandlerMapping

extends AbstractHandlerMapping

Abstract base class for url-mapped HandlerMapping implementations. Provides infrastructure for mapping handlers to URLs and configurable URL lookup. For information on the latter, see alwaysUseFullPath property.

Supports direct matches (given "/test" -> registered "/test") and "*" matches (given "/test" -> registered "/t*").

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.

registerHandler

protected void registerHandler(java.lang.String urlPath,
                               java.lang.Object handler)

Register the given handler instance for the given URL path.

Parameters:

urlPath - URL the bean is mapped to

handler - the handler instance

lookupHandler

protected java.lang.Object lookupHandler(java.lang.String urlPath)

Lookup a handler instance for the given URL path. Supports direct matches (given "/test" -> registered "/test") and "*" matches (given "/test" -> registered "/t*").

Parameters:

urlPath - URL the bean is mapped to

Returns:

the associated handler instance, or null if not found

initHandler

protected java.lang.Object initHandler(java.lang.String beanName,
                                       java.lang.String urlPath)
                                throws ApplicationContextException

Initialize the handler object with the given name in the bean factory. This includes setting the LocaleResolver and mapped URL if aware.

Parameters:

beanName - name of the bean in the application context

urlPath - URL the bean is mapped to

Returns:

the initialized handler instance

Throws:

ApplicationContextException - if the bean wasn't found in the context

getHandlerInternal

protected java.lang.Object getHandlerInternal(javax.servlet.http.HttpServletRequest request)

Lookup a handler for the URL path of the given request.

Overrides:

getHandlerInternal in class AbstractHandlerMapping

Parameters:

request - current HTTP request

Returns:

the looked up handler instance, or null
