org.springframework.web.portlet.handler.AbstractHandlerMapping
org.springframework.web.portlet.handler.AbstractMapBasedHandlerMapping
public abstract class AbstractMapBasedHandlerMapping
Abstract base class for HandlerMapping
 implementations that rely on a map which caches handler objects per lookup key.
 Supports arbitrary lookup keys, and automatically resolves handler bean names
 into handler bean instances.

public void setLazyInitHandlers(boolean lazyInitHandlers)
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.
