Class SimpleUrlHandlerMapping

java.lang.Object
  org.springframework.context.support.ApplicationObjectSupport
      org.springframework.web.context.support.WebApplicationObjectSupport
          org.springframework.web.servlet.handler.AbstractHandlerMapping
              org.springframework.web.servlet.handler.AbstractUrlHandlerMapping
                  org.springframework.web.servlet.handler.SimpleUrlHandlerMapping

All Implemented Interfaces:: ApplicationContextAware, Ordered, ServletContextAware, HandlerMapping

public class SimpleUrlHandlerMapping
extends AbstractUrlHandlerMapping
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 non-singleton 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*"). Note that the default is to map within the current servlet mapping if applicable; see the "alwaysUseFullPath" property for details. For details on the pattern options, see the AntPathMatcher javadoc.

Method Summary

Map getUrlMap()
          Allow Map access to the URL path mappings, with the option to add or override specific entries.

void initApplicationContext()
          Calls the registerHandlers(java.util.Map) method in addition to the superclass's initialization.

protected void registerHandlers(Map urlMap)
          Register all handlers specified in the URL map for the corresponding paths.

void setMappings(Properties mappings)
          Map URL paths to handler bean names.

void setUrlMap(Map urlMap)
          Set a Map with URL paths as keys and handler beans (or handler bean names) as values.

Constructor Detail

SimpleUrlHandlerMapping

public SimpleUrlHandlerMapping()

Method Detail

setMappings

public void setMappings(Properties mappings)

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

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

Parameters:: mappings - properties with URLs as keys and bean names as values
See Also:: setUrlMap(java.util.Map)

setUrlMap

public void setUrlMap(Map urlMap)

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