    - #### setEmbeddedValueResolver

          public void setEmbeddedValueResolver(org.springframework.util.StringValueResolver resolver)

      从接口复制的说明: `EmbeddedValueResolverAware`
      Set the StringValueResolver to use for resolving embedded definition values.
      指定者:
        `setEmbeddedValueResolver` 在接口中 `EmbeddedValueResolverAware`

    - #### addFormatter

          public void addFormatter(Formatter<?> formatter)

      从接口复制的说明: `FormatterRegistry`
      Adds a Formatter to format fields of a specific type. The field type is implied by the parameterized Formatter instance.
      指定者:
        `addFormatter` 在接口中 `FormatterRegistry`
      参数:
        `formatter` - the formatter to add
      另请参阅:
        `FormatterRegistry.addFormatterForFieldType(Class, Formatter)`

    - #### addFormatterForFieldType

          public void addFormatterForFieldType(Class<?> fieldType,
                                               Formatter<?> formatter)

      从接口复制的说明: `FormatterRegistry`
      Adds a Formatter to format fields of the given type.

      On print, if the Formatter's type T is declared and `fieldType` is not assignable to T, a coercion to T will be attempted before delegating to `formatter` to print a field value. On parse, if the parsed object returned by `formatter` is not assignable to the runtime field type, a coercion to the field type will be attempted before returning the parsed field value.

      指定者:
        `addFormatterForFieldType` 在接口中 `FormatterRegistry`
      参数:
        `fieldType` - the field type to format
        `formatter` - the formatter to add

    - #### addFormatterForFieldType

          public void addFormatterForFieldType(Class<?> fieldType,
                                               Printer<?> printer,
                                               Parser<?> parser)

      从接口复制的说明: `FormatterRegistry`
      Adds a Printer/Parser pair to format fields of a specific type. The formatter will delegate to the specified `printer` for printing and the specified `parser` for parsing.

      On print, if the Printer's type T is declared and `fieldType` is not assignable to T, a coercion to T will be attempted before delegating to `printer` to print a field value. On parse, if the object returned by the Parser is not assignable to the runtime field type, a coercion to the field type will be attempted before returning the parsed field value.

      指定者:
        `addFormatterForFieldType` 在接口中 `FormatterRegistry`
      参数:
        `fieldType` - the field type to format
        `printer` - the printing part of the formatter
        `parser` - the parsing part of the formatter

    - #### addFormatterForFieldAnnotation

          public void addFormatterForFieldAnnotation(AnnotationFormatterFactory<? extends Annotation> annotationFormatterFactory)

      从接口复制的说明: `FormatterRegistry`
      Adds a Formatter to format fields annotated with a specific format annotation.
      指定者:
        `addFormatterForFieldAnnotation` 在接口中 `FormatterRegistry`
      参数:
        `annotationFormatterFactory` - the annotation formatter factory to add
