@Deprecated
public class DefaultAnnotationHandlerMapping
extends AbstractDetectingUrlHandlerMapping

Implementation of the HandlerMapping interface that maps handlers based on HTTP paths expressed through the RequestMapping annotation at the type or method level.

Registered by default in DispatcherServlet on Java 5+. NOTE: If you define custom HandlerMapping beans in your DispatcherServlet context, you need to add a DefaultAnnotationHandlerMapping bean explicitly, since custom HandlerMapping beans replace the default mapping strategies. Defining a DefaultAnnotationHandlerMapping also allows for registering custom interceptors:

 <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
   <property name="interceptors">
     ...
   </property>
 </bean>

Annotated controllers are usually marked with the Controller stereotype at the type level. This is not strictly necessary when RequestMapping is applied at the type level (since such a handler usually implements the Controller interface). However, Controller is required for detecting RequestMapping annotations at the method level if RequestMapping is not present at the type level.

NOTE: Method-level mappings are only allowed to narrow the mapping expressed at the class level (if any). HTTP paths need to uniquely map onto specific handler beans, with any given HTTP path only allowed to be mapped onto one specific handler bean (not spread across multiple handler beans). It is strongly recommended to co-locate related handler methods into the same bean.

The AnnotationMethodHandlerAdapter is responsible for processing annotated handler methods, as mapped by this HandlerMapping. For RequestMapping at the type level, specific HandlerAdapters such as SimpleControllerHandlerAdapter apply.

Method Detail

setUseDefaultSuffixPattern

public void setUseDefaultSuffixPattern(boolean useDefaultSuffixPattern)

Deprecated.

Set whether to register paths using the default suffix pattern as well: i.e. whether "/users" should be registered as "/users.*" and "/users/" too.

Default is "true". Turn this convention off if you intend to interpret your @RequestMapping paths strictly.

Note that paths which include a ".xxx" suffix or end with "/" already will not be transformed using the default suffix pattern in any case.

determineUrlsForHandler

protected String[] determineUrlsForHandler(String beanName)

Deprecated.

Checks for presence of the RequestMapping annotation on the handler class and on any of its methods.

Specified by:

determineUrlsForHandler in class AbstractDetectingUrlHandlerMapping

Parameters:

beanName - the name of the candidate bean

Returns:

the URLs determined for the bean, or null or an empty array if none

determineUrlsForHandlerMethods

protected String[] determineUrlsForHandlerMethods(Class<?> handlerType,
                                                  boolean hasTypeLevelMapping)

Deprecated.

Derive URL mappings from the handler's method-level mappings.

Parameters:

handlerType - the handler type to introspect

hasTypeLevelMapping - whether the method-level mappings are nested within a type-level mapping

Returns:

the array of mapped URLs

determineUrlsForHandlerMethods

protected String[] determineUrlsForHandlerMethods(Class<?> handlerType)

Deprecated.

Derive URL mappings from the handler's method-level mappings.

Parameters:

handlerType - the handler type to introspect

Returns:

the array of mapped URLs

addUrlsForPath

protected void addUrlsForPath(Set<String> urls,
                              String path)

Deprecated.

Add URLs and/or URL patterns for the given path.

Parameters:

urls - the Set of URLs for the current bean

path - the currently introspected path

validateHandler

protected void validateHandler(Object handler,
                               HttpServletRequest request)
                        throws Exception

Deprecated.

Validate the given annotated handler against the current request.

Overrides:

validateHandler in class AbstractUrlHandlerMapping

Parameters:

handler - the handler object to validate

request - current HTTP request

Throws:

Exception - if validation failed

See Also:

validateMapping(org.springframework.web.bind.annotation.RequestMapping, javax.servlet.http.HttpServletRequest)

validateMapping

protected void validateMapping(RequestMapping mapping,
                               HttpServletRequest request)

Deprecated.

Validate the given type-level mapping metadata against the current request, checking HTTP request method and parameter conditions.

Parameters:

mapping - the mapping metadata to validate

request - current HTTP request

Throws:

Exception - if validation failed

supportsTypeLevelMappings

protected boolean supportsTypeLevelMappings()

Deprecated.
