RequestMappingHandlerAdapter
@Deprecated public class AnnotationMethodHandlerAdapter extends WebContentGenerator implements HandlerAdapter, Ordered, BeanFactoryAware
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
.

public AnnotationMethodHandlerAdapter()
public void setAlwaysUseFullPath(boolean alwaysUseFullPath)
Default is "false".
public void setUrlDecode(boolean urlDecode)
Uses either the request encoding or the default encoding according to the Servlet spec (ISO-8859-1).
UrlPathHelper.setUrlDecode(boolean)
public void setUrlPathHelper(UrlPathHelper urlPathHelper)
Use this to override the default UrlPathHelper with a custom subclass, or to share common UrlPathHelper settings across multiple HandlerMappings and HandlerAdapters.
public void setPathMatcher(PathMatcher pathMatcher)
Default is AntPathMatcher
.
public void setMethodNameResolver(MethodNameResolver methodNameResolver)
@RequestMapping
annotation).
Will only kick in when the handler method cannot be resolved uniquely through the annotation metadata already.
public void setWebBindingInitializer(WebBindingInitializer webBindingInitializer)
public void setSessionAttributeStore(SessionAttributeStore sessionAttributeStore)
Default is DefaultSessionAttributeStore
,
storing session attributes in the HttpSession, using the same attribute name as in the model.
public void setCacheSecondsForSessionAttributeHandlers(int cacheSecondsForSessionAttributeHandlers)
@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.
public void setSynchronizeOnSession(boolean synchronizeOnSession)
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.
public void setParameterNameDiscoverer(ParameterNameDiscoverer parameterNameDiscoverer)
Default is a DefaultParameterNameDiscoverer
.
public void setCustomArgumentResolver(WebArgumentResolver argumentResolver)
Such a custom WebArgumentResolver will kick in first, having a chance to resolve an argument value before the standard argument handling kicks in.
public void setCustomArgumentResolvers(WebArgumentResolver... argumentResolvers)
Any such custom WebArgumentResolver will kick in first, having a chance to resolve an argument value before the standard argument handling kicks in.
public void setCustomModelAndViewResolver(ModelAndViewResolver customModelAndViewResolver)
Such a custom ModelAndViewResolver will kick in first, having a chance to resolve a return value before the standard ModelAndView handling kicks in.
public void setCustomModelAndViewResolvers(ModelAndViewResolver... customModelAndViewResolvers)
Any such custom ModelAndViewResolver will kick in first, having a chance to resolve a return value before the standard ModelAndView handling kicks in.
public void setMessageConverters(HttpMessageConverter<?>[] messageConverters)
These converters are used to convert from and to HTTP requests and responses.
public HttpMessageConverter<?>[] getMessageConverters()
public void setOrder(int order)
Default value is Integer.MAX_VALUE
, meaning that it's non-ordered.
Ordered.getOrder()
public int getOrder()
Ordered
Higher values are interpreted as lower priority. As a consequence,
the object with the lowest value has the highest priority (somewhat
analogous to Servlet load-on-startup
values).
Same order values will result in arbitrary sort positions for the affected objects.

Invoked after the population of normal bean properties
but before an initialization callback such as
InitializingBean.afterPropertiesSet()
or a custom init-method.
