类 AbstractMapBasedHandlerMapping<K>

构造器详细资料

• AbstractMapBasedHandlerMapping

  public AbstractMapBasedHandlerMapping()

方法详细资料

• setLazyInitHandlers

  public void setLazyInitHandlers​(boolean lazyInitHandlers)

  Set whether to lazily initialize handlers. Only applicable to singleton handlers, as prototypes are always lazily initialized. Default is false, as eager initialization allows for more efficiency through referencing the handler objects directly.

  If you want to allow your handlers to be lazily initialized, make them "lazy-init" and set this flag to true. Just making them "lazy-init" will not work, as they are initialized through the references from the handler mapping in this case.

• getHandlerInternal

  protected Object getHandlerInternal​(PortletRequest request)
                               throws Exception

  Determines a handler for the computed lookup key for the given request.

  指定者:

  getHandlerInternal 在类中 AbstractHandlerMapping

  参数:

  request - current portlet request

  返回:

  the corresponding handler instance, or null if none found

  抛出:

  Exception - if there is an internal error

• getLookupKey

  protected abstract K getLookupKey​(PortletRequest request)
                             throws Exception

  Build a lookup key for the given request.

  参数:

  request - current portlet request

  返回:

  the lookup key (never null)

  抛出:

  Exception - if key computation failed

• registerHandlers

  protected void registerHandlers​(Map<K,​?> handlerMap)
                           throws BeansException

  Register all handlers specified in the Portlet mode map for the corresponding modes.

  参数:

  handlerMap - Map with lookup keys as keys and handler beans or bean names as values

  抛出:

  BeansException - if the handler couldn't be registered

• registerHandler

  protected void registerHandler​(K lookupKey,
                                 Object handler)
                          throws BeansException,
                                 IllegalStateException

  Register the given handler instance for the given parameter value.

  参数:

  lookupKey - the key to map the handler onto

  handler - the handler instance or handler bean name String (a bean name will automatically be resolved into the corresponding handler bean)

  抛出:

  BeansException - if the handler couldn't be registered

  IllegalStateException - if there is a conflicting handler registered

• registerHandler

  protected void registerHandler​(K lookupKey,
                                 Object handler,
                                 AbstractMapBasedHandlerMapping.PortletRequestMappingPredicate predicate)
                          throws BeansException,
                                 IllegalStateException

  Register the given handler instance for the given parameter value.

  参数:

  lookupKey - the key to map the handler onto

  handler - the handler instance or handler bean name String (a bean name will automatically be resolved into the corresponding handler bean)

  predicate - a predicate object for this handler (may be null), determining a match with the primary lookup key

  抛出:

  BeansException - if the handler couldn't be registered

  IllegalStateException - if there is a conflicting handler registered
