supports

public boolean supports(Object handler)

从接口复制的说明: HandlerAdapter

Given a handler instance, return whether support or not this RequestHandlerAdapter can support it. Typical RequestHandlerAdapters will base the decision on the handler type. RequestHandlerAdapters will usually only support one handler type each.

A typical implementation:

return (handler instanceof MyHandler);

指定者:

supports 在接口中 HandlerAdapter

参数:

handler - handler object to check

返回:

whether support or not this object can use the given handler

handle

public Object handle(RequestContext context,
 Object handler)
              throws Throwable

从接口复制的说明: HandlerAdapter

Use the given handler to handle this request. The workflow that is required may vary widely.

this result will handle by ReturnValueHandler

指定者:

handle 在接口中 HandlerAdapter

参数:

context - current HTTP request context

handler - handler to use. This object must have previously been passed to the supports method of this interface, which must have returned true.

返回:

an object with the name of the view and the required model data, or null if the request has been handled directly

抛出:

Throwable - in case of errors
