- org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter

所有已实现的接口:
HandlerAdapter
```
public class HttpRequestHandlerAdapter
extends Object
implements HandlerAdapter
```
Adapter to use the plain HttpRequestHandler interface with the generic DispatcherServlet. Supports handlers that implement the LastModified interface.
This is an SPI class, not used directly by application code.

    从接口复制的说明: HandlerAdapter
    Given a handler instance, return whether or not this HandlerAdapter can support it. Typical HandlerAdapters will base the decision on the handler type. HandlerAdapters 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 or not this object can use the given handler
  - handle
```
public ModelAndView handle(HttpServletRequest request,
                           HttpServletResponse response,
                           Object handler)
                    throws Exception
```
    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.
    指定者:
    handle 在接口中 HandlerAdapter
    参数:
    request - current HTTP request
    response - current HTTP response
    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:
    ModelAndView object with the name of the view and the required model data, or null if the request has been handled directly
    抛出:
    Exception - in case of errors
  - getLastModified
```
public long getLastModified(HttpServletRequest request,
                            Object handler)
```
    从接口复制的说明: HandlerAdapter
    Same contract as for HttpServlet's getLastModified method. Can simply return -1 if there's no support in the handler class.
    指定者:
    getLastModified 在接口中 HandlerAdapter
    参数:
    request - current HTTP request
    handler - handler to use
    返回:
    the lastModified value for the given handler
