从接口复制的说明: HandlerMapping

Return a handler and any interceptors for this request. The choice may be made on request URL, session state, or any factor the implementing class chooses.

The returned HandlerExecutionChain contains a handler Object, rather than even a tag interface, so that handlers are not constrained in any way. For example, a HandlerAdapter could be written to allow another framework's handler objects to be used.

Returns null if no match was found. This is not an error. The DispatcherServlet will query all registered HandlerMapping beans to find a match, and only decide there is an error if none can find a handler.

指定者:

getHandler 在接口中 HandlerMapping

参数:

request - Current request context

返回:

a fgA instance containing handler object and any interceptors, or null if no mapping found

抛出:

Exception - if there is an internal error
