方法详细资料

• setSupportedMediaTypes

  public void setSupportedMediaTypes​(List<MediaType> supportedMediaTypes)

  Set the supported media types for this view.

  Default is "text/html;charset=UTF-8".

• getSupportedMediaTypes

  public List<MediaType> getSupportedMediaTypes()

  Get the configured media types supported by this view.

  指定者:

  getSupportedMediaTypes 在接口中 View

• setDefaultCharset

  public void setDefaultCharset​(Charset defaultCharset)

  Set the default charset for this view, used when the content type does not contain one.

  Default is UTF 8.

• getDefaultCharset

  public Charset getDefaultCharset()

  Get the default charset, used when the content type does not contain one.

• setRequestContextAttribute

  public void setRequestContextAttribute​(@Nullable
                                         String requestContextAttribute)

  Set the name of the RequestContext attribute for this view.

  Default is none (null).

• getRequestContextAttribute

  @Nullable
  public String getRequestContextAttribute()

  Get the name of the RequestContext attribute for this view, if any.

• setBeanName

  public void setBeanName​(@Nullable
                          String beanName)

  Set the view's name. Helpful for traceability.

  Framework code must call this when constructing views.

  指定者:

  setBeanName 在接口中 BeanNameAware

  参数:

  beanName - the name of the bean in the factory. Note that this name is the actual bean name used in the factory, which may differ from the originally specified name: in particular for inner bean names, the actual bean name might have been made unique through appending "#..." suffixes. Use the BeanFactoryUtils.originalBeanName(String) method to extract the original bean name (without suffix), if desired.

• getBeanName

  @Nullable
  public String getBeanName()

  Get the view's name.

  Should never be null if the view was correctly configured.

• setApplicationContext

  public void setApplicationContext​(@Nullable
                                    ApplicationContext applicationContext)

  从接口复制的说明: ApplicationContextAware
  Set the ApplicationContext that this object runs in. Normally this call will be used to initialize the object.

  Invoked after population of normal bean properties but before an init callback such as InitializingBean.afterPropertiesSet() or a custom init-method. Invoked after ResourceLoaderAware.setResourceLoader(org.springframework.core.io.ResourceLoader), ApplicationEventPublisherAware.setApplicationEventPublisher(org.springframework.context.ApplicationEventPublisher) and MessageSourceAware, if applicable.

  指定者:

  setApplicationContext 在接口中 ApplicationContextAware

  参数:

  applicationContext - the ApplicationContext object to be used by this object

  BeanInitializationException

• getApplicationContext

  @Nullable
  public ApplicationContext getApplicationContext()

• obtainApplicationContext

  protected final ApplicationContext obtainApplicationContext()

  Obtain the ApplicationContext for actual use.

  返回:

  the ApplicationContext (never null)

  抛出:

  IllegalStateException - if the ApplicationContext cannot be obtained

• render

  public reactor.core.publisher.Mono<Void> render​(@Nullable
                                                  Map<String,​?> model,
                                                  @Nullable
                                                  MediaType contentType,
                                                  ServerWebExchange exchange)

  Prepare the model to render.

  指定者:

  render 在接口中 View

  参数:

  model - a map with attribute names as keys and corresponding model objects as values (the map can also be null in case of an empty model)

  contentType - the content type selected to render with, which should match one of the supported media types

  exchange - the current exchange

  返回:

  a Mono that represents when and if rendering succeeds

• getModelAttributes

  protected reactor.core.publisher.Mono<Map<String,​Object>> getModelAttributes​(@Nullable
                                                                                     Map<String,​?> model,
                                                                                     ServerWebExchange exchange)

  Prepare the model to use for rendering.

  The default implementation creates a combined output Map that includes model as well as static attributes with the former taking precedence.

• resolveAsyncAttributes

  protected reactor.core.publisher.Mono<Void> resolveAsyncAttributes​(Map<String,​Object> model,
                                                                     ServerWebExchange exchange)

  Use the configured ReactiveAdapterRegistry to adapt asynchronous attributes to Mono<T> or Mono<List<T>> and then wait to resolve them into actual values. When the returned Mono<Void> completes, the asynchronous attributes in the model will have been replaced with their corresponding resolved values.

  返回:

  result a Mono that completes when the model is ready

  从以下版本开始:

  5.1.8

• resolveAsyncAttributes

  @Deprecated
  protected reactor.core.publisher.Mono<Void> resolveAsyncAttributes​(Map<String,​Object> model)

  已过时。

  as of 5.1.8 this method is still invoked but it is a no-op. Please use resolveAsyncAttributes(Map, ServerWebExchange) instead. It is invoked after this one and does the actual work.
  Use the configured ReactiveAdapterRegistry to adapt asynchronous attributes to Mono<T> or Mono<List<T>> and then wait to resolve them into actual values. When the returned Mono<Void> completes, the asynchronous attributes in the model would have been replaced with their corresponding resolved values.

  返回:

  result Mono that completes when the model is ready

• createRequestContext

  protected RequestContext createRequestContext​(ServerWebExchange exchange,
                                                Map<String,​Object> model)

  Create a RequestContext to expose under the specified attribute name.

  The default implementation creates a standard RequestContext instance for the given exchange and model.

  Can be overridden in subclasses to create custom instances.

  参数:

  exchange - the current exchange

  model - a combined output Map (never null), with dynamic values taking precedence over static attributes

  返回:

  the RequestContext instance

  另请参阅:

  setRequestContextAttribute(java.lang.String)

• getRequestDataValueProcessor

  @Nullable
  protected RequestDataValueProcessor getRequestDataValueProcessor()

  Get the RequestDataValueProcessor to use.

  The default implementation looks in the ApplicationContext for a RequestDataValueProcessor bean with the name REQUEST_DATA_VALUE_PROCESSOR_BEAN_NAME.

  返回:

  the RequestDataValueProcessor, or null if there is none in the application context

• renderInternal

  protected abstract reactor.core.publisher.Mono<Void> renderInternal​(Map<String,​Object> renderAttributes,
                                                                      @Nullable
                                                                      MediaType contentType,
                                                                      ServerWebExchange exchange)

  Subclasses must implement this method to actually render the view.

  参数:

  renderAttributes - combined output Map (never null), with dynamic values taking precedence over static attributes

  contentType - the content type selected to render with, which should match one of the supported media types

  exchange - current exchange

  返回:

  a Mono that represents when and if rendering succeeds
