修饰符和类型	方法	说明
`boolean`	`canRead(ResolvableType elementType, MediaType mediaType)`	Whether the given object type is supported by this reader.
`Charset`	`getDefaultCharset()`	Return the configured default charset.
`int`	`getMaxInMemorySize()`	Return the `configured` byte count limit.
`List<MediaType>`	`getReadableMediaTypes()`	Return the `MediaType`'s that this reader supports.
`reactor.core.publisher.Flux<MultiValueMap<String,String>>`	`read(ResolvableType elementType, ReactiveHttpInputMessage message, Map<String,Object> hints)`	Read from the input message and encode to a stream of objects.
`reactor.core.publisher.Mono<MultiValueMap<String,String>>`	`readMono(ResolvableType elementType, ReactiveHttpInputMessage message, Map<String,Object> hints)`	Read from the input message and encode to a single object.
`void`	`setDefaultCharset(Charset charset)`	Set the default character set to use for reading form data when the request Content-Type header does not explicitly specify it.
`void`	`setMaxInMemorySize(int byteCount)`	Set the max number of bytes for input form data.

  - DEFAULT_CHARSET
```
public static final Charset DEFAULT_CHARSET
```
    The default charset used by the reader.

```
public FormHttpMessageReader()
```

  - setDefaultCharset
```
public void setDefaultCharset(Charset charset)
```
    Set the default character set to use for reading form data when the request Content-Type header does not explicitly specify it.
    By default this is set to "UTF-8".
  - getDefaultCharset
```
public Charset getDefaultCharset()
```
    Return the configured default charset.
  - setMaxInMemorySize
```
public void setMaxInMemorySize(int byteCount)
```
    Set the max number of bytes for input form data. As form data is buffered before it is parsed, this helps to limit the amount of buffering. Once the limit is exceeded, DataBufferLimitException is raised.
    By default this is set to 256K.
    参数:
    byteCount - the max number of bytes to buffer, or -1 for unlimited
    从以下版本开始:
    5.1.11
  - getMaxInMemorySize
```
public int getMaxInMemorySize()
```
    Return the configured byte count limit.
    从以下版本开始:
    5.1.11
  - canRead
```
public boolean canRead(ResolvableType elementType,
                       @Nullable
                       MediaType mediaType)
```
    从接口复制的说明: HttpMessageReader
    Whether the given object type is supported by this reader.
    指定者:
    canRead 在接口中 HttpMessageReader<MultiValueMap<String,String>>
    参数:
    elementType - the type of object to check
    mediaType - the media type for the read (possibly null)
    返回:
    true if readable, false otherwise
  - read
```
public reactor.core.publisher.Flux<MultiValueMap<String,String>> read(ResolvableType elementType,
                                                                            ReactiveHttpInputMessage message,
                                                                            Map<String,Object> hints)
```

    Read from the input message and encode to a stream of objects.
    指定者:
    read 在接口中 HttpMessageReader<MultiValueMap<String,String>>
    参数:
    elementType - the type of objects in the stream which must have been previously checked via HttpMessageReader.canRead(ResolvableType, MediaType)
    message - the message to read from
    hints - additional information about how to read and decode the input
    返回:
    the decoded stream of elements
  - readMono
```
public reactor.core.publisher.Mono<MultiValueMap<String,String>> readMono(ResolvableType elementType,
                                                                                ReactiveHttpInputMessage message,
                                                                                Map<String,Object> hints)
```
    从接口复制的说明: HttpMessageReader
    Read from the input message and encode to a single object.
    指定者:
    readMono 在接口中 HttpMessageReader<MultiValueMap<String,String>>
    参数:
