方法详细资料

• setStrategies

  public void setStrategies​(@Nullable
                            List<ContentNegotiationStrategy> strategies)

  Set the exact list of strategies to use.

  Note: use of this method is mutually exclusive with use of all other setters in this class which customize a default, fixed set of strategies. See class level doc for more details.

  参数:

  strategies - the strategies to use

• setFavorPathExtension

  @Deprecated
  public void setFavorPathExtension​(boolean favorPathExtension)

  已过时。

  as of 5.2.4. See class-level note on the deprecation of path extension config options. As there is no replacement for this method, for the time being it's necessary to continue using it in order to set it to false. In 5.3 when false becomes the default, use of this property will no longer be necessary.
  Whether the path extension in the URL path should be used to determine the requested media type.

  By default this is set to true in which case a request for /hotels.pdf will be interpreted as a request for "application/pdf" regardless of the 'Accept' header.

• setMediaTypes

  public void setMediaTypes​(Properties mediaTypes)

  Add a mapping from a key to a MediaType where the key are normalized to lowercase and may have been extracted from a path extension, a filename extension, or passed as a query parameter.

  The parameter strategy requires such mappings in order to work while the path extension strategy can fall back on lookups via ServletContext.getMimeType(java.lang.String) and MediaTypeFactory.

  Note: Mappings registered here may be accessed via ContentNegotiationManager.getMediaTypeMappings() and may be used not only in the parameter and path extension strategies. For example, with the Spring MVC config, e.g. @EnableWebMvc or <mvc:annotation-driven>, the media type mappings are also plugged in to:

  • Determine the media type of static resources served with ResourceHttpRequestHandler.
  • Determine the media type of views rendered with ContentNegotiatingViewResolver.
  • List safe extensions for RFD attack detection (check the Spring Framework reference docs for details).

  参数:

  mediaTypes - media type mappings

• addMediaType

  public void addMediaType​(String key,
                           MediaType mediaType)

  An alternative to setMediaTypes(java.util.Properties) for programmatic registrations.

• addMediaTypes

  public void addMediaTypes​(@Nullable
                            Map<String,​MediaType> mediaTypes)

  An alternative to setMediaTypes(java.util.Properties) for programmatic registrations.

• setIgnoreUnknownPathExtensions

  @Deprecated
  public void setIgnoreUnknownPathExtensions​(boolean ignore)

  已过时。

  as of 5.2.4. See class-level note on the deprecation of path extension config options.
  Whether to ignore requests with path extension that cannot be resolved to any media type. Setting this to false will result in an HttpMediaTypeNotAcceptableException if there is no match.

  By default this is set to true.

• setUseJaf

  @Deprecated
  public void setUseJaf​(boolean useJaf)

  已过时。

  as of 5.0, in favor of setUseRegisteredExtensionsOnly(boolean), which has reverse behavior.
  Indicate whether to use the Java Activation Framework as a fallback option to map from file extensions to media types.

• setUseRegisteredExtensionsOnly

  public void setUseRegisteredExtensionsOnly​(boolean useRegisteredExtensionsOnly)

  When favorPathExtension or setFavorParameter(boolean) is set, this property determines whether to use only registered MediaType mappings or to allow dynamic resolution, e.g. via MediaTypeFactory.

  By default this is not set in which case dynamic resolution is on.

• setFavorParameter

  public void setFavorParameter​(boolean favorParameter)

  Whether a request parameter ("format" by default) should be used to determine the requested media type. For this option to work you must register media type mappings.

  By default this is set to false.

  setParameterName(java.lang.String)

• setParameterName

  public void setParameterName​(String parameterName)

  Set the query parameter name to use when setFavorParameter(boolean) is on.

  The default parameter name is "format".

• setIgnoreAcceptHeader

  public void setIgnoreAcceptHeader​(boolean ignoreAcceptHeader)

  Whether to disable checking the 'Accept' request header.

  By default this value is set to false.

• setDefaultContentType

  public void setDefaultContentType​(MediaType contentType)

  Set the default content type to use when no content type is requested.

  By default this is not set.

  setDefaultContentTypeStrategy(org.springframework.web.accept.ContentNegotiationStrategy)

• setDefaultContentTypes

  public void setDefaultContentTypes​(List<MediaType> contentTypes)

  Set the default content types to use when no content type is requested.

  By default this is not set.

  setDefaultContentTypeStrategy(org.springframework.web.accept.ContentNegotiationStrategy)

• setDefaultContentTypeStrategy

  public void setDefaultContentTypeStrategy​(ContentNegotiationStrategy strategy)

  Set a custom ContentNegotiationStrategy to use to determine the content type to use when no content type is requested.

  By default this is not set.

• setServletContext

  public void setServletContext​(ServletContext servletContext)

  Invoked by Spring to inject the ServletContext.

  指定者:

  setServletContext 在接口中 ServletContextAware

  参数:

  servletContext - the ServletContext object to be used by this object

• afterPropertiesSet

  public void afterPropertiesSet()

  从接口复制的说明: InitializingBean
  Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.

  This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

  指定者:

  afterPropertiesSet 在接口中 InitializingBean

• build

  public ContentNegotiationManager build()

  Create and initialize a ContentNegotiationManager instance.

  从以下版本开始:

  5.0

• getObject

  @Nullable
  public ContentNegotiationManager getObject()

  从接口复制的说明: FactoryBean
  Return an instance (possibly shared or independent) of the object managed by this factory.

  As with a BeanFactory, this allows support for both the Singleton and Prototype design pattern.

  If this FactoryBean is not fully initialized yet at the time of the call (for example because it is involved in a circular reference), throw a corresponding FactoryBeanNotInitializedException.

  As of Spring 2.0, FactoryBeans are allowed to return null objects. The factory will consider this as normal value to be used; it will not throw a FactoryBeanNotInitializedException in this case anymore. FactoryBean implementations are encouraged to throw FactoryBeanNotInitializedException themselves now, as appropriate.

  指定者:

  getObject 在接口中 FactoryBean<ContentNegotiationManager>

  返回:

  an instance of the bean (can be null)

  FactoryBeanNotInitializedException

• getObjectType

  public Class<?> getObjectType()

  从接口复制的说明: FactoryBean
  Return the type of object that this FactoryBean creates, or null if not known in advance.

  This allows one to check for specific types of beans without instantiating objects, for example on autowiring.

  In the case of implementations that are creating a singleton object, this method should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.

  This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.

  NOTE: Autowiring will simply ignore FactoryBeans that return null here. Therefore it is highly recommended to implement this method properly, using the current state of the FactoryBean.

  指定者:

  getObjectType 在接口中 FactoryBean<ContentNegotiationManager>

  返回:

  the type of object that this FactoryBean creates, or null if not known at the time of the call

• isSingleton

  public boolean isSingleton()

  从接口复制的说明: FactoryBean
  Is the object managed by this factory a singleton? That is, will FactoryBean.getObject() always return the same object (a reference that can be cached)?

  NOTE: If a FactoryBean indicates to hold a singleton object, the object returned from getObject() might get cached by the owning BeanFactory. Hence, do not return true unless the FactoryBean always exposes the same reference.

  The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there.

  NOTE: This method returning false does not necessarily indicate that returned objects are independent instances. An implementation of the extended SmartFactoryBean interface may explicitly indicate independent instances through its SmartFactoryBean.isPrototype() method. Plain FactoryBean implementations which do not implement this extended interface are simply assumed to always return independent instances if the isSingleton() implementation returns false.

  The default implementation returns true, since a FactoryBean typically manages a singleton instance.

  指定者:

  isSingleton 在接口中 FactoryBean<ContentNegotiationManager>

  返回:

  whether the exposed object is a singleton
