```
public class AnnotationMethodHandlerAdapter
extends PortletContentGenerator
implements HandlerAdapter, Ordered, BeanFactoryAware
```
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.

```
public void setWebBindingInitializer(WebBindingInitializer webBindingInitializer)

  - setSessionAttributeStore
```
public void setSessionAttributeStore(SessionAttributeStore sessionAttributeStore)
```
    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.
  - 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.

  - 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 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.

  - setParameterNameDiscoverer
```
public void setParameterNameDiscoverer(ParameterNameDiscoverer parameterNameDiscoverer)
```
    Set the ParameterNameDiscoverer to use for resolving method parameter names if needed (e.g. for default attribute names).
    Default is a DefaultParameterNameDiscoverer.
  - setCustomArgumentResolver
```
public void setCustomArgumentResolver(WebArgumentResolver argumentResolver)
```
    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.
  - setCustomArgumentResolvers
```
public void setCustomArgumentResolvers(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(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 an return value before the standard ModelAndView handling kicks in.
  - setCustomModelAndViewResolvers
```
public void setCustomModelAndViewResolvers(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 an return value before the standard ModelAndView handling kicks in.
  - 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.
    另请参阅:
    Ordered.getOrder()
  - getOrder
```
public int getOrder()
```
    从接口复制的说明: Ordered
    Get the order value of this object.
    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.
    指定者:
