方法详细资料

• setIgnoreDefaultModelOnRedirect

  public void setIgnoreDefaultModelOnRedirect​(boolean ignoreDefaultModelOnRedirect)

  By default the content of the "default" model is used both during rendering and redirect scenarios. Alternatively controller methods can declare an argument of type RedirectAttributes and use it to provide attributes to prepare the redirect URL.

  Setting this flag to true guarantees the "default" model is never used in a redirect scenario even if a RedirectAttributes argument is not declared. Setting it to false means the "default" model may be used in a redirect if the controller method doesn't declare a RedirectAttributes argument.

  The default setting is false.

• setViewName

  public void setViewName​(String viewName)

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

• getViewName

  public String getViewName()

  Return the view name to be resolved by the DispatcherServlet via a ViewResolver, or null if a View object is set.

• setView

  public void setView​(Object view)

  Set a View object to be used by the DispatcherServlet. Will override any pre-existing view name or View.

• getView

  public Object getView()

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

• isViewReference

  public boolean isViewReference()

  Whether the view is a view reference specified via a name to be resolved by the DispatcherServlet via a ViewResolver.

• getModel

  public ModelMap getModel()

  Return the model to use -- either the "default" or the "redirect" model. The default model is used if redirectModelScenario=false or there is no redirect model (i.e. RedirectAttributes was not declared as a method argument) and ignoreDefaultModelOnRedirect=false.

• getDefaultModel

  public ModelMap getDefaultModel()

  Return the "default" model created at instantiation.

  In general it is recommended to use getModel() instead which returns either the "default" model (template rendering) or the "redirect" model (redirect URL preparation). Use of this method may be needed for advanced cases when access to the "default" model is needed regardless, e.g. to save model attributes specified via @SessionAttributes.

  返回:

  the default model (never null)

  从以下版本开始:

  4.1.4

• setRedirectModel

  public void setRedirectModel​(ModelMap redirectModel)

  Provide a separate model instance to use in a redirect scenario.

  The provided additional model however is not used unless setRedirectModelScenario(boolean) gets set to true to signal an actual redirect scenario.

• setRedirectModelScenario

  public void setRedirectModelScenario​(boolean redirectModelScenario)

  Whether the controller has returned a redirect instruction, e.g. a "redirect:" prefixed view name, a RedirectView instance, etc.

• setStatus

  public void setStatus​(HttpStatus status)

  Provide an HTTP status that will be passed on to with the ModelAndView used for view rendering purposes.

  从以下版本开始:

  4.3

• getStatus

  public HttpStatus getStatus()

  Return the configured HTTP status, if any.

  从以下版本开始:

  4.3

• setBindingDisabled

  public void setBindingDisabled​(String attributeName)

  Programmatically register an attribute for which data binding should not occur, not even for a subsequent @ModelAttribute declaration.

  参数:

  attributeName - the name of the attribute

  从以下版本开始:

  4.3

• isBindingDisabled

  public boolean isBindingDisabled​(String name)

  Whether binding is disabled for the given model attribute.

  从以下版本开始:

  4.3

• setBinding

  public void setBinding​(String attributeName,
                         boolean enabled)

  Register whether data binding should occur for a corresponding model attribute, corresponding to an @ModelAttribute(binding=true/false) declaration.

  Note: While this flag will be taken into account by isBindingDisabled(java.lang.String), a hard setBindingDisabled(java.lang.String) declaration will always override it.

  参数:

  attributeName - the name of the attribute

  从以下版本开始:

  4.3.13

• getSessionStatus

  public SessionStatus getSessionStatus()

  Return the SessionStatus instance to use that can be used to signal that session processing is complete.

• setRequestHandled

  public void setRequestHandled​(boolean requestHandled)

  Whether the request has been handled fully within the handler, e.g. @ResponseBody method, and therefore view resolution is not necessary. This flag can also be set when controller methods declare an argument of type ServletResponse or OutputStream).

  The default value is false.

• isRequestHandled

  public boolean isRequestHandled()

  Whether the request has been handled fully within the handler.

• addAttribute

  public ModelAndViewContainer addAttribute​(String name,
                                            Object value)

  Add the supplied attribute to the underlying model. A shortcut for getModel().addAttribute(String, Object).

• addAttribute

  public ModelAndViewContainer addAttribute​(Object value)

  Add the supplied attribute to the underlying model. A shortcut for getModel().addAttribute(Object).

• addAllAttributes

  public ModelAndViewContainer addAllAttributes​(Map<String,​?> attributes)

  Copy all attributes to the underlying model. A shortcut for getModel().addAllAttributes(Map).

• mergeAttributes

  public ModelAndViewContainer mergeAttributes​(Map<String,​?> attributes)

  Copy attributes in the supplied Map with existing objects of the same name taking precedence (i.e. not getting replaced). A shortcut for getModel().mergeAttributes(Map<String, ?>).

• removeAttributes

  public ModelAndViewContainer removeAttributes​(Map<String,​?> attributes)

  Remove the given attributes from the model.

• containsAttribute

  public boolean containsAttribute​(String name)

  Whether the underlying model contains the given attribute name. A shortcut for getModel().containsAttribute(String).

• toString

  public String toString()

  Return diagnostic information.
