java.lang.Object
- org.springframework.web.server.ServerWebExchangeDecorator

所有已实现的接口:
ServerWebExchange
```
public class ServerWebExchangeDecorator
extends Object
implements ServerWebExchange
```
A convenient base class for classes that need to wrap another ServerWebExchange. Pre-implements all methods by delegating to the wrapped instance.
Note: if the purpose for using a decorator is to override properties like getPrincipal(), consider using ServerWebExchange.mutate() instead.
从以下版本开始:

    Return the web session for the current request. Always guaranteed to return an instance either matching to the session id requested by the client, or with a new session id either because the client did not specify one or because the underlying session had expired. Use of this method does not automatically create a session. See WebSession for more details.

```
    从接口复制的说明: ServerWebExchange
    Return the form data from the body of the request if the Content-Type is "application/x-www-form-urlencoded" or an empty map otherwise.
    Note: calling this method causes the request body to be read and parsed in full and the resulting MultiValueMap is cached so that this method is safe to call more than once.
    指定者:
    getFormData 在接口中 ServerWebExchange
  - getMultipartData
```
public reactor.core.publisher.Mono<MultiValueMap<String,Part>> getMultipartData()
```
    从接口复制的说明: ServerWebExchange
    Return the parts of a multipart request if the Content-Type is "multipart/form-data" or an empty map otherwise.
    Note: calling this method causes the request body to be read and parsed in full and the resulting MultiValueMap is cached so that this method is safe to call more than once.
    Note:the contents of each part is not cached, and can only be read once.

```
    从接口复制的说明: ServerWebExchange
    Check whether the requested resource has been modified given the supplied ETag (entity tag) and last-modified timestamp as determined by the application. Also transparently prepares the response, setting HTTP status, and adding "ETag" and "Last-Modified" headers when applicable. This method works with conditional GET/HEAD requests as well as with conditional POST/PUT/DELETE requests.
    Note: The HTTP specification recommends setting both ETag and Last-Modified values, but you can also use #checkNotModified(String) or ServerWebExchange.checkNotModified(Instant).
    指定者:
    checkNotModified 在接口中 ServerWebExchange
    参数:
    etag - the entity tag that the application determined for the underlying resource. This parameter will be padded with quotes (") if necessary.

    返回:
    true if the request does not require further processing.
  - transformUrl
```
public String transformUrl(String url)
```
    从接口复制的说明: ServerWebExchange

    指定者:
    transformUrl 在接口中 ServerWebExchange
    参数:

    从接口复制的说明: ServerWebExchange
    Register an additional URL transformation function for use with ServerWebExchange.transformUrl(java.lang.String). The given function can be used to insert an id for authentication, a nonce for CSRF protection, etc.
    Note that the given function is applied after any previously registered functions.
    指定者:
    addUrlTransformer 在接口中 ServerWebExchange
    参数:
