```
public abstract class AbstractMessageReaderArgumentResolver
extends HandlerMethodArgumentResolverSupport
```
Abstract base class for argument resolvers that resolve method arguments by reading the request body with an HttpMessageReader.
Applies validation if the method argument is annotated with @javax.validation.Valid or Validated. Validation failure results in an ServerWebInputException.

getMessageReaders

public List<HttpMessageReader<?>> getMessageReaders()

Return the configured message converters.

readBody

protected reactor.core.publisher.Mono<Object> readBody(MethodParameter bodyParameter,
                                                       boolean isBodyRequired,

                                                       ServerWebExchange exchange)

Read the body from a method argument with HttpMessageReader.

Parameters:: bodyParameter - the MethodParameter to read; isBodyRequired - true if the body is required; bindingContext - the binding context to use; exchange - the current exchange
Returns:: the body
See Also:: readBody(MethodParameter, MethodParameter, boolean, BindingContext, ServerWebExchange)

                                                       @Nullable

                                                       ServerWebExchange exchange)

Read the body from a method argument with HttpMessageReader.

Parameters:: bodyParam - represents the element type for the body; actualParam - the actual method argument type; possibly different from bodyParam, e.g. for an HttpEntity argument; isBodyRequired - true if the body is required; bindingContext - the binding context to use; exchange - the current exchange
Returns:: a Mono with the value to use for the method argument
Since:: 5.0.2
