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, e.g. a registered "/test" matches "/test", and various Ant-style pattern matches, e.g. a registered "/t*" pattern matches both "/test" and "/team", "/test/*" matches all paths in the "/test" directory, "/test/**" matches all paths below "/test". For syntax details, see the PathMatcher class.

Constructor Detail

SimpleUrlHandlerMapping

public SimpleUrlHandlerMapping()

Method Detail

setUrlMap

public void setUrlMap(Map urlMap)

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

Supports direct URL matches and Ant-style pattern matches. For syntax details, see the PathMatcher class.

Parameters:

urlMap - map with URLs as keys and beans as values

PathMatcher

setMappings

public void setMappings(Properties mappings)

Map URL paths to handler bean names. This the typical way of configuring this HandlerMapping.

Supports direct URL matches and Ant-style pattern matches. For syntax details, see the PathMatcher class.

Parameters:

mappings - properties with URLs as keys and bean names as values

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 but rather just on first initialization of this object's context reference.

Overrides:

initApplicationContext in class ApplicationObjectSupport

Throws:

BeansException - if thrown by ApplicationContext methods
