BeanNameUrlHandlerMapping (Spring Framework API 2.0) - Spring Framework 2.0.5 API 文档英文版
org.springframework.web.servlet.handler
Class BeanNameUrlHandlerMapping
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.BeanNameUrlHandlerMapping
- All Implemented Interfaces:
- ApplicationContextAware, Ordered, ServletContextAware, HandlerMapping
public class BeanNameUrlHandlerMapping
- extends AbstractUrlHandlerMapping
Implementation of the 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
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
"alwaysUseFullPath"
property for details.
For details on the pattern options, see the
AntPathMatcher
javadoc.

BeanNameUrlHandlerMapping
public BeanNameUrlHandlerMapping()
setDetectHandlersInAncestorContexts
public void setDetectHandlersInAncestorContexts(boolean detectHandlersInAncestorContexts)
- 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.
initApplicationContext
public void initApplicationContext()
throws ApplicationContextException
- Calls the
detectHandlers()
method in addition to the
superclass's initialization.
- Overrides:
initApplicationContext
in class AbstractHandlerMapping
- Throws:
ApplicationContextException
- in case of initialization errors- See Also:
AbstractHandlerMapping.extendInterceptors(java.util.List)
,
AbstractHandlerMapping.initInterceptors()
detectHandlers
protected void detectHandlers()
throws BeansException
- 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:
determineUrlsForHandler(java.lang.String)
determineUrlsForHandler
protected String[] determineUrlsForHandler(String beanName)
- Check name and aliases of the given bean for URLs,
detected by starting with "/".
- Parameters:
beanName
- the name of the candidate bean
- Returns:
- the URLs determined for the bean, or an empty array if none
