Method Detail

setViewName

public void setViewName(java.lang.String viewName)

Set a view name for the ModelAndView to return, to be resolved by the DispatcherServlet via a ViewResolver. Will override any pre-existing view name or View.

getViewName

public java.lang.String getViewName()

Return the name of the view to delegate to, or null if using a View instance.

setView

public void setView(View view)

Set a View object for the ModelAndView to return. Will override any pre-existing view name or View.

Since:

4.1

getView

public View getView()

Return the View object, or null if we are using a view name to be resolved by the DispatcherServlet via a ViewResolver.

Since:

4.1

setStatusCode

public void setStatusCode(HttpStatus statusCode)

Configure the HTTP status code that this controller should set on the response.

When a "redirect:" prefixed view name is configured, there is no need to set this property since RedirectView will do that. However this property may still be used to override the 3xx status code of RedirectView. For full control over redirecting provide a RedirectView instance.

If the status code is 204 and no view is configured, the request is fully handled within the controller.

Since:

4.1

getStatusCode

public HttpStatus getStatusCode()

Return the configured HTTP status code or null.

Since:

4.1

setStatusOnly

public void setStatusOnly(boolean statusOnly)

The property can be used to indicate the request is considered fully handled within the controller and that no view should be used for rendering. Useful in combination with setStatusCode(org.springframework.http.HttpStatus).

By default this is set to false.

Since:

4.1

isStatusOnly

public boolean isStatusOnly()

Whether the request is fully handled within the controller.

handleRequestInternal

protected ModelAndView handleRequestInternal(HttpServletRequest request,
                                             HttpServletResponse response)
                                      throws java.lang.Exception

Return a ModelAndView object with the specified view name.

The content of the "input" FlashMap is also added to the model.

Specified by:

handleRequestInternal in class AbstractController

Throws:

java.lang.Exception
