All Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method	Description
`long`	`getLastModified(HttpServletRequest request, Object handler)`	This implementation expects the handler to be an `HandlerMethod`.
`protected abstract long`	`getLastModifiedInternal(HttpServletRequest request, HandlerMethod handlerMethod)`	Same contract as for `HttpServlet.getLastModified(HttpServletRequest)`.
`int`	`getOrder()`	Get the order value of this object.
`ModelAndView`	`handle(HttpServletRequest request, HttpServletResponse response, Object handler)`	This implementation expects the handler to be an `HandlerMethod`.
`protected abstract ModelAndView`	`handleInternal(HttpServletRequest request, HttpServletResponse response, HandlerMethod handlerMethod)`	Use the given handler method to handle the request.
`void`	`setOrder(int order)`	Specify the order value for this HandlerAdapter bean.
`boolean`	`supports(Object handler)`	This implementation expects the handler to be an `HandlerMethod`.
`protected abstract boolean`	`supportsInternal(HandlerMethod handlerMethod)`	Given a handler method, return whether or not this adapter can support it.

public AbstractHandlerMethodAdapter()
```
- Method Detail
  - setOrder
```
public void setOrder(int order)
```
    Specify the order value for this HandlerAdapter bean.
    The default value is Ordered.LOWEST_PRECEDENCE, meaning non-ordered.
    See Also:
    Ordered.getOrder()
  - getOrder
```
public int getOrder()
```
    Description copied from interface: Ordered
    Get the order value of this object.
    Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet load-on-startup values).
    Same order values will result in arbitrary sort positions for the affected objects.
    Specified by:
    getOrder in interface Ordered
    Returns:
    the order value
    See Also:
    Ordered.HIGHEST_PRECEDENCE, Ordered.LOWEST_PRECEDENCE
  - supports
```
public final boolean supports(Object handler)
```
    This implementation expects the handler to be an HandlerMethod.
    Specified by:
    supports in interface HandlerAdapter
    Parameters:
    handler - the handler instance to check
    Returns:
    whether or not this adapter can adapt the given handler
  - supportsInternal
```
protected abstract boolean supportsInternal(HandlerMethod handlerMethod)
```
    Given a handler method, return whether or not this adapter can support it.
    Parameters:
    handlerMethod - the handler method to check
    Returns:
    whether or not this adapter can adapt the given method
  - handle
```
public final ModelAndView handle(HttpServletRequest request,
                                 HttpServletResponse response,
                                 Object handler)
                          throws Exception
```
    This implementation expects the handler to be an HandlerMethod.
    Specified by:
    handle in interface HandlerAdapter
    Parameters:
    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.
    Returns:
    ModelAndView object with the name of the view and the required model data, or null if the request has been handled directly
    Throws:
    Exception - in case of errors
  - handleInternal
```
protected abstract ModelAndView handleInternal(HttpServletRequest request,
                                               HttpServletResponse response,
                                               HandlerMethod handlerMethod)
                                        throws Exception
```
    Use the given handler method to handle the request.
    Parameters:
    request - current HTTP request
    response - current HTTP response
    handlerMethod - handler method to use. This object must have previously been passed to the supportsInternal(HandlerMethod) this interface, which must have returned true.
    Returns:
    ModelAndView object with the name of the view and the required model data, or null if the request has been handled directly
    Throws:
    Exception - in case of errors
  - getLastModified
```
public final long getLastModified(HttpServletRequest request,
                                  Object handler)
```
    This implementation expects the handler to be an HandlerMethod.
    Specified by:
    getLastModified in interface HandlerAdapter
    Parameters:
    request - current HTTP request
    handler - handler to use
    Returns:
    the lastModified value for the given handler
    See Also:
    HttpServlet.getLastModified(javax.servlet.http.HttpServletRequest), LastModified.getLastModified(javax.servlet.http.HttpServletRequest)
  - getLastModifiedInternal
```
protected abstract long getLastModifiedInternal(HttpServletRequest request,
                                                HandlerMethod handlerMethod)
```
    Same contract as for HttpServlet.getLastModified(HttpServletRequest).
    Parameters:
    request - current HTTP request
    handlerMethod - handler method to use
    Returns:
    the lastModified value for the given handler
