Constructor Details

ExtendedWebExchangeDataBinder

public ExtendedWebExchangeDataBinder(@Nullable Object target)

Create a new instance, with default object name.

Parameters:

target - the target object to bind onto (or null if the binder is just used to convert a plain parameter value)

See Also:

• DataBinder.DEFAULT_OBJECT_NAME

ExtendedWebExchangeDataBinder

public ExtendedWebExchangeDataBinder(@Nullable Object target,
 String objectName)

Method Details

addHeaderPredicate

public void addHeaderPredicate(Predicate<String> headerPredicate)

Add a Predicate that filters the header names to use for data binding. Multiple predicates are combined with AND.

Parameters:

headerPredicate - the predicate to add

Since:

6.2.1

setHeaderPredicate

public void setHeaderPredicate(Predicate<String> headerPredicate)

Set the Predicate that filters the header names to use for data binding.

Note that this method resets any previous predicates that may have been set, including headers excluded by default such as the RFC 9218 defined "Priority" header.

Parameters:

headerPredicate - the predicate to add

Since:

6.2.1

getValuesToBind

public reactor.core.publisher.Mono<Map<String,Object>> getValuesToBind(ServerWebExchange exchange)

Description copied from class: WebExchangeDataBinder

Obtain the values for data binding. By default, this delegates to WebExchangeDataBinder.extractValuesToBind(ServerWebExchange).

Overrides:

getValuesToBind in class WebExchangeDataBinder

Parameters:

exchange - the current exchange

Returns:

a map of bind values
