Implementation of the HandlerAdapter
interface that maps handler methods based on portlet modes, action/render phases
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
.

Return the order value of this object, with a higher value meaning greater in terms of sorting.
Normally starting with 0, with Integer.MAX_VALUE
indicating the greatest value. Same order values will result
in arbitrary positions for the affected objects.
Higher values can be interpreted as lower priority. As a consequence, the object with the lowest value has highest priority (somewhat analogous to Servlet "load-on-startup" values).

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.
Set a custom WebArgumentResolver 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.
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.
Set a custom ModelAndViewResolvers to use for special method return types. Such a custom ModelAndViewResolver will kick in first, having a chance to resolve an return value before the standard ModelAndView handling kicks in.
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 an return value before the standard ModelAndView handling kicks in.
Specify the order value for this HandlerAdapter bean.
Default value is Integer.MAX_VALUE
, meaning that it's non-ordered.
Set the ParameterNameDiscoverer to use for resolving method parameter names if needed (e.g. for default attribute names).
Default is a LocalVariableTableParameterNameDiscoverer
.
Specify the strategy to store session attributes with.
Default is DefaultSessionAttributeStore
,
storing session attributes in the PortletSession, using the same
attribute name as in the model.
Set if controller execution should be synchronized on the session, to serialize parallel invocations from the same client.
More specifically, the execution of each handler 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 PortletSession 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.
HttpSessionMutexListener
Specify a WebBindingInitializer which will apply pre-configured configuration to every DataBinder that this controller uses.
Given a handler instance, return whether or not this HandlerAdapter can support it. Typical HandlerAdapters will base the decision on the handler type. HandlerAdapters will usually only support one handler type each.
A typical implementation:
return (handler instanceof MyHandler);
