public class AnnotationMethodHandlerAdapter
extends org.springframework.web.servlet.support.WebContentGenerator
implements org.springframework.web.servlet.HandlerAdapter, org.springframework.core.Ordered, org.springframework.beans.factory.BeanFactoryAware

Implementation of the HandlerAdapter interface that maps handler methods based on HTTP paths, HTTP methods and request parameters expressed through the RequestMapping annotation.

Supports request parameter binding through the RequestParam annotation. Also supports the ModelAttribute annotation for exposing model attribute values to the view, as well as InitBinder for binder initialization methods and SessionAttributes for automatic session management of specific attributes.

This adapter can be customized through various bean properties. A common use case is to apply shared binder initialization logic through a custom WebBindingInitializer.

Template method for creating a new ServletRequestDataBinder instance.

The default implementation creates a standard ServletRequestDataBinder. This can be overridden for custom ServletRequestDataBinder subclasses.

Parameters:

request - current HTTP request

target - the target object to bind onto (or null if the binder is just used to convert a plain parameter value)

objectName - the objectName of the target object

Returns:

the ServletRequestDataBinder instance to use

Throws:

Exception - in case of invalid state or arguments

Throws:

Exception

setAlwaysUseFullPath

public void setAlwaysUseFullPath(boolean alwaysUseFullPath)

Set if URL lookup should always use the full path within the current servlet context. Else, the path within the current servlet mapping is used if applicable (that is, in the case of a ".../*" servlet mapping in web.xml).

Default is "false".

See Also:

UrlPathHelper.setAlwaysUseFullPath(boolean)

setBeanFactory

public void setBeanFactory(org.springframework.beans.factory.BeanFactory beanFactory)

Specified by:

setBeanFactory in interface org.springframework.beans.factory.BeanFactoryAware

setCacheSecondsForSessionAttributeHandlers

public void setCacheSecondsForSessionAttributeHandlers(int cacheSecondsForSessionAttributeHandlers)

Cache content produced by @SessionAttributes annotated handlers for the given number of seconds. Default is 0, preventing caching completely.

In contrast to the "cacheSeconds" property which will apply to all general handlers (but not to @SessionAttributes annotated handlers), this setting will apply to @SessionAttributes annotated handlers only.

See Also:

WebContentGenerator.setCacheSeconds(int), SessionAttributes

setCustomArgumentResolver

public void setCustomArgumentResolver(org.springframework.web.bind.support.WebArgumentResolver argumentResolver)

Set a custom WebArgumentResolvers to use for special method parameter types.

Such a custom WebArgumentResolver will kick in first, having a chance to resolve an argument value before the standard argument handling kicks in.

setCustomArgumentResolvers

public void setCustomArgumentResolvers(org.springframework.web.bind.support.WebArgumentResolver[] argumentResolvers)

Set one or more custom WebArgumentResolvers to use for special method parameter types.

Any such custom WebArgumentResolver will kick in first, having a chance to resolve an argument value before the standard argument handling kicks in.

setCustomModelAndViewResolver

public void setCustomModelAndViewResolver(org.springframework.web.servlet.mvc.annotation.ModelAndViewResolver customModelAndViewResolver)

Set a custom ModelAndViewResolvers to use for special method return types.

Such a custom ModelAndViewResolver will kick in first, having a chance to resolve a return value before the standard ModelAndView handling kicks in.

setCustomModelAndViewResolvers

public void setCustomModelAndViewResolvers(org.springframework.web.servlet.mvc.annotation.ModelAndViewResolver[] customModelAndViewResolvers)

Set one or more custom ModelAndViewResolvers to use for special method return types.

Any such custom ModelAndViewResolver will kick in first, having a chance to resolve a return value before the standard ModelAndView handling kicks in.

setDefaultMediaType

public void setDefaultMediaType(org.springframework.http.MediaType defaultContentType)

Sets the default content type.

This content type will be used when file extension, parameter, nor Accept header define a content-type, either through being disabled or empty.

setMediaTypeOrder

public void setMediaTypeOrder(List<String> mediaTypeOrder)

setMediaTypes

public void setMediaTypes(Map<String,String> mediaTypes)

Sets the mapping from file extensions to media types.

setMessageConverters

public void setMessageConverters(org.springframework.http.converter.HttpMessageConverter<?>[] messageConverters)

Set the message body converters to use.

These converters are used to convert from and to HTTP requests and responses.

setMethodNameResolver

public void setMethodNameResolver(org.springframework.web.servlet.mvc.multiaction.MethodNameResolver methodNameResolver)

Set the MethodNameResolver to use for resolving default handler methods (carrying an empty @RequestMapping annotation).

Will only kick in when the handler method cannot be resolved uniquely through the annotation metadata already.

setOrder

public void setOrder(int order)

Specify the order value for this HandlerAdapter bean.

Default value is Integer.MAX_VALUE, meaning that it's non-ordered.

See Also:

Ordered.getOrder()

setParameterName

public void setParameterName(String parameterName)

Sets the parameter name that can be used to determine the requested media type if the #setFavorParameter(boolean) property is true. The default parameter name is format.

setParameterNameDiscoverer

public void setParameterNameDiscoverer(org.springframework.core.ParameterNameDiscoverer parameterNameDiscoverer)

Set the ParameterNameDiscoverer to use for resolving method parameter names if needed (e.g. for default attribute names).

Default is a LocalVariableTableParameterNameDiscoverer.

setPathMatcher

public void setPathMatcher(org.springframework.util.PathMatcher pathMatcher)

Set the PathMatcher implementation to use for matching URL paths against registered URL patterns.

Default is AntPathMatcher.

setSessionAttributeStore

public void setSessionAttributeStore(org.springframework.web.bind.support.SessionAttributeStore sessionAttributeStore)

Specify the strategy to store session attributes with.

Default is DefaultSessionAttributeStore, storing session attributes in the HttpSession, using the same attribute name as in the model.

setSynchronizeOnSession

public void setSynchronizeOnSession(boolean synchronizeOnSession)

Set if controller execution should be synchronized on the session, to serialize parallel invocations from the same client.

More specifically, the execution of the handleRequestInternal method will get synchronized if this flag is "true". The best available session mutex will be used for the synchronization; ideally, this will be a mutex exposed by HttpSessionMutexListener.

The session mutex is guaranteed to be the same object during the entire lifetime of the session, available under the key defined by the SESSION_MUTEX_ATTRIBUTE constant. It serves as a safe reference to synchronize on for locking on the current session.

In many cases, the HttpSession reference itself is a safe mutex as well, since it will always be the same object reference for the same active logical session. However, this is not guaranteed across different servlet containers; the only 100% safe way is a session mutex.

See Also:

HttpSessionMutexListener, WebUtils.getSessionMutex(javax.servlet.http.HttpSession)

setUrlDecode

public void setUrlDecode(boolean urlDecode)

Set if context path and request URI should be URL-decoded. Both are returned undecoded by the Servlet API, in contrast to the servlet path.

Uses either the request encoding or the default encoding according to the Servlet spec (ISO-8859-1).

See Also:

UrlPathHelper.setUrlDecode(boolean)

setUrlPathHelper

public void setUrlPathHelper(org.springframework.web.util.UrlPathHelper urlPathHelper)

Set the UrlPathHelper to use for resolution of lookup paths.

Use this to override the default UrlPathHelper with a custom subclass, or to share common UrlPathHelper settings across multiple HandlerMappings and HandlerAdapters.

setWebBindingInitializer

public void setWebBindingInitializer(org.springframework.web.bind.support.WebBindingInitializer webBindingInitializer)

Specify a WebBindingInitializer which will apply pre-configured configuration to every DataBinder that this controller uses.

supports

public boolean supports(Object handler)

Specified by:

supports in interface org.springframework.web.servlet.HandlerAdapter
