public class SimpleUrlHandlerMapping

extends AbstractUrlHandlerMapping

Implementation of the HandlerMapping interface to map from URLs to request handler beans. Supports both mapping to bean instances and mapping to bean names: The latter is required for prototype handlers.

The "urlMap" property is suitable for populating the handler map with bean references, e.g. via the map element in XML bean definitions.

Mappings to bean names can be set via the "mappings" property, in a form accepted by the java.util.Properties class, like as follows:
/welcome.html=ticketController /show.html=ticketController
The syntax is PATH=HANDLER_BEAN_NAME. If the path doesn't begin with a slash, one is prepended.

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

Constructor Detail

SimpleUrlHandlerMapping

public SimpleUrlHandlerMapping()

Method Detail

setUrlMap

public void setUrlMap(java.util.Map urlMap)

Set a Map with URLs as keys and handler beans as values. Convenient for population with bean references.

Parameters:

urlMap - map with URLs as keys and beans as values

setMappings

public void setMappings(java.util.Properties mappings)

Set URL to handler bean name mappings from a Properties object.

Parameters:

mappings - properties with URL as key and bean name as value

initApplicationContext

public void initApplicationContext()
                            throws BeansException

Description copied from class: ApplicationObjectSupport

Subclasses can override this for custom initialization behavior. Gets called by setApplicationContext() after setting the context instance.

Note: Does not get called on reinitialization of the context.

Overrides:

initApplicationContext in class ApplicationObjectSupport

Throws:

BeansException - if thrown by application context methods
