org.springframework.web.servlet.handler.AbstractHandlerMapping
   org.springframework.web.servlet.handler.AbstractUrlHandlerMapping
      org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping

BeanNameUrlHandlerMapping
public class BeanNameUrlHandlerMapping extends AbstractUrlHandlerMapping (Code)
Implementation of the org.springframework.web.servlet.HandlerMapping interface that map from URLs to beans with names that start with a slash ("/"), similar to how Struts maps URLs to action names.

This is the default implementation used by the org.springframework.web.servlet.DispatcherServlet , but it is somewhat naive. A SimpleUrlHandlerMapping or a custom handler mapping should be used by preference.

The mapping is from URL to bean name. Thus an incoming URL "/foo" would map to a handler named "/foo", or to "/foo /foo2" in case of multiple mappings to a single handler. Note: In XML definitions, you'll need to use an alias name="/foo" in the bean definition, as the XML id may not contain slashes.

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 BeanNameUrlHandlerMapping.setAlwaysUseFullPath "alwaysUseFullPath" property for details. For details on the pattern options, see the org.springframework.util.AntPathMatcher javadoc.

Method Summary
protected  voiddetectHandlers()
     Register all handlers found in the current ApplicationContext.
protected  String[]determineUrlsForHandler(String beanName)
     Check name and aliases of the given bean for URLs, detected by starting with "/".
public  voidinitApplicationContext()
     Calls the BeanNameUrlHandlerMapping.detectHandlers() method in addition to the superclass's initialization.
public  voidsetDetectHandlersInAncestorContexts(boolean detectHandlersInAncestorContexts)
     Set whether to detect handler beans in ancestor ApplicationContexts.



Method Detail
detectHandlers
protected void detectHandlers() throws BeansException(Code)
Register all handlers found in the current ApplicationContext. Any bean whose name appears to be a URL is considered a handler.
throws:
  BeansException - if the handler couldn't be registered
See Also:   BeanNameUrlHandlerMapping.determineUrlsForHandler



determineUrlsForHandler
protected String[] determineUrlsForHandler(String beanName)(Code)
Check name and aliases of the given bean for URLs, detected by starting with "/".
Parameters:
  beanName - the name of the candidate bean the URLs determined for the bean, or an empty array if none



initApplicationContext
public void initApplicationContext() throws ApplicationContextException(Code)
Calls the BeanNameUrlHandlerMapping.detectHandlers() method in addition to the superclass's initialization.



setDetectHandlersInAncestorContexts
public void setDetectHandlersInAncestorContexts(boolean detectHandlersInAncestorContexts)(Code)
Set whether to detect handler beans in ancestor ApplicationContexts.

Default is "false": Only handler beans in the current ApplicationContext will be detected, that is, only in the context that this BeanNameUrlHandlerMapping itself is defined in (typically the current DispatcherServlet's context).

Switch this flag on to detect handler beans in ancestor contexts (typically the Spring root WebApplicationContext) as well.
