类 ResourceRegionHttpMessageConverter

构造器详细资料

• ResourceRegionHttpMessageConverter

  public ResourceRegionHttpMessageConverter()

方法详细资料

• getDefaultContentType

  protected MediaType getDefaultContentType​(Object object)

  从类复制的说明: AbstractHttpMessageConverter
  Returns the default content type for the given type. Called when AbstractHttpMessageConverter.write(T, org.springframework.http.MediaType, org.springframework.http.HttpOutputMessage) is invoked without a specified content type parameter.

  By default, this returns the first element of the supportedMediaTypes property, if any. Can be overridden in subclasses.

  覆盖:

  getDefaultContentType 在类中 AbstractHttpMessageConverter<Object>

  参数:

  object - the type to return the content type for

  返回:

  the content type, or null if not known

• canRead

  public boolean canRead​(Class<?> clazz,
                         @Nullable
                         MediaType mediaType)

  从类复制的说明: AbstractHttpMessageConverter
  This implementation checks if the given class is supported, and if the supported media typesinclude the given media type.

  指定者:

  canRead 在接口中 HttpMessageConverter<Object>

  覆盖:

  canRead 在类中 AbstractHttpMessageConverter<Object>

  参数:

  clazz - the class to test for readability

  mediaType - the media type to read (can be null if not specified); typically the value of a Content-Type header.

  返回:

  true if readable; false otherwise

• canRead

  public boolean canRead​(Type type,

                         MediaType mediaType)

  从接口复制的说明: GenericHttpMessageConverter
  Indicates whether the given type can be read by this converter. This method should perform the same checks than HttpMessageConverter.canRead(Class, MediaType) with additional ones related to the generic type.

  指定者:

  canRead 在接口中 GenericHttpMessageConverter<Object>

  覆盖:

  canRead 在类中 AbstractGenericHttpMessageConverter<Object>

  参数:

  type - the (potentially generic) type to test for readability

  contextClass - a context class for the target type, for example a class in which the target type appears in a method signature (can be null)

  mediaType - the media type to read, can be null if not specified. Typically the value of a Content-Type header.

  返回:

  true if readable; false otherwise

• read

  public Object read​(Type type,

                     HttpInputMessage inputMessage)
              throws IOException,
                     HttpMessageNotReadableException

  从接口复制的说明: GenericHttpMessageConverter
  Read an object of the given type form the given input message, and returns it.

  参数:

  type - the (potentially generic) type of object to return. This type must have previously been passed to the canRead method of this interface, which must have returned true.

  contextClass - a context class for the target type, for example a class in which the target type appears in a method signature (can be null)

  inputMessage - the HTTP input message to read from

  返回:

  the converted object

  抛出:

  IOException - in case of I/O errors

  HttpMessageNotReadableException - in case of conversion errors

                                 throws IOException,
                                        HttpMessageNotReadableException

  从类复制的说明: AbstractHttpMessageConverter
  Abstract template method that reads the actual object. Invoked from AbstractHttpMessageConverter.read(java.lang.Class<? extends T>, org.springframework.http.HttpInputMessage).

  指定者:

  readInternal 在类中 AbstractHttpMessageConverter<Object>

  参数:

  clazz - the type of object to return

  inputMessage - the HTTP input message to read from

  返回:

  the converted object

  抛出:

  IOException - in case of I/O errors

  HttpMessageNotReadableException - in case of conversion errors

• canWrite

  从类复制的说明: AbstractHttpMessageConverter
  This implementation checks if the given class is supported, and if the supported media types include the given media type.

  指定者:
