Class ThrowawayControllerHandlerAdapter

    java.lang.Object
      org.springframework.web.servlet.mvc.throwaway.ThrowawayControllerHandlerAdapter

All Implemented Interfaces:
  HandlerAdapter

Deprecated. as of Spring 2.5, in favor of annotation-based controllers. To be removed in Spring 3.0.

    public class ThrowawayControllerHandlerAdapter

extends Object
implements HandlerAdapter

Adapter to use the ThrowawayController workflow interface with the generic DispatcherServlet. Does not support last-modified checks.

This is an SPI class, not used directly by application code. It can be explicitly configured in a DispatcherServlet context, to use a customized version instead of the default ThrowawayControllerHandlerAdapter.

Field Summary
`static String` `DEFAULT_COMMAND_NAME` Deprecated.

Constructor Summary
`ThrowawayControllerHandlerAdapter()` Deprecated.

Method Summary
`protected ServletRequestDataBinder` `createBinder(HttpServletRequest request, ThrowawayController command)` Deprecated. Create a new binder instance for the given command and request.
`String` `getCommandName()` Deprecated. Return the name of the command in the model.
`long` `getLastModified(HttpServletRequest request, Object handler)` Deprecated. This implementation always returns -1, as last-modified checks are not supported.
`ModelAndView` `handle(HttpServletRequest request, HttpServletResponse response, Object handler)` Deprecated. This implementation binds request parameters to the ThrowawayController instance and then calls `execute` on it.
`protected void` `initBinder(HttpServletRequest request, ServletRequestDataBinder binder)` Deprecated. Initialize the given binder instance, for example with custom editors.
`void` `setCommandName(String commandName)` Deprecated. Set the name of the command in the model.
`boolean` `supports(Object handler)` Deprecated. Given a handler instance, return whether or not this HandlerAdapter can support it.

Constructor Detail

### ThrowawayControllerHandlerAdapter

    public ThrowawayControllerHandlerAdapter()

  Deprecated.

Method Detail

### setCommandName

    public final void setCommandName(String commandName)

  Deprecated.
  Set the name of the command in the model. The command object will be included in the model under this name.

### getCommandName

    public final String getCommandName()

  Deprecated.
  Return the name of the command in the model.

### supports

    public boolean supports(Object handler)

  Deprecated.
  Description copied from interface: `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);`

  Specified by:
    `supports` in interface `HandlerAdapter`
  Parameters:
    `handler` - handler object to check
  Returns:
    whether or not this object can use the given handler

### handle

    public ModelAndView handle(HttpServletRequest request,
                               HttpServletResponse response,
                               Object handler)
                        throws Exception

  Deprecated.
  This implementation binds request parameters to the ThrowawayController instance and then calls `execute` on it.

  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
  See Also:
    `createBinder(javax.servlet.http.HttpServletRequest, org.springframework.web.servlet.mvc.throwaway.ThrowawayController)`, `ThrowawayController.execute()`

### createBinder

    protected ServletRequestDataBinder createBinder(HttpServletRequest request,
                                                    ThrowawayController command)
                                             throws Exception

  Deprecated.
  Create a new binder instance for the given command and request.

  Called by `bindAndValidate`. Can be overridden to plug in custom ServletRequestDataBinder subclasses.

  Default implementation creates a standard ServletRequestDataBinder, sets the specified MessageCodesResolver (if any), and invokes initBinder. Note that `initBinder` will not be invoked if you override this method!

  Parameters:
    `request` - current HTTP request
    `command` - the command to bind onto
  Returns:
    the new binder instance
  Throws:
    `Exception` - in case of invalid state or arguments
  See Also:
    `initBinder(javax.servlet.http.HttpServletRequest, org.springframework.web.bind.ServletRequestDataBinder)`, `getCommandName()`

### initBinder

    protected void initBinder(HttpServletRequest request,
                              ServletRequestDataBinder binder)
                       throws Exception

  Deprecated.
  Initialize the given binder instance, for example with custom editors. Called by `createBinder`.

  This method allows you to register custom editors for certain fields of your command class. For instance, you will be able to transform Date objects into a String pattern and back, in order to allow your JavaBeans to have Date properties and still be able to set and display them in an HTML interface.

  Default implementation is empty.

  Parameters:
    `request` - current HTTP request
    `binder` - new binder instance
  Throws:
    `Exception` - in case of invalid state or arguments
  See Also:
    `createBinder(javax.servlet.http.HttpServletRequest, org.springframework.web.servlet.mvc.throwaway.ThrowawayController)`, `DataBinder.registerCustomEditor(java.lang.Class, java.beans.PropertyEditor)`, `CustomDateEditor`

### getLastModified

    public long getLastModified(HttpServletRequest request,
                                Object handler)

  Deprecated.
  This implementation always returns -1, as last-modified checks are not supported.

  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)`
