org.springframework.web.reactive.result.method.annotation.AbstractNamedValueArgumentResolver

org.springframework.web.reactive.result.method.annotation.AbstractNamedValueSyncArgumentResolver

All Implemented Interfaces:

HandlerMethodArgumentResolver, SyncHandlerMethodArgumentResolver

Direct Known Subclasses:

CookieValueMethodArgumentResolver, ExpressionValueMethodArgumentResolver, PathVariableMethodArgumentResolver, RequestAttributeMethodArgumentResolver, RequestHeaderMethodArgumentResolver, RequestParamMethodArgumentResolver

public abstract class AbstractNamedValueSyncArgumentResolver
extends AbstractNamedValueArgumentResolver
implements SyncHandlerMethodArgumentResolver

An extension of AbstractNamedValueArgumentResolver for named value resolvers that are synchronous and yet non-blocking. Sub-classes implement the synchronous resolveNamedValue(java.lang.String, org.springframework.core.MethodParameter, org.springframework.web.server.ServerWebExchange) to which the asynchronous resolveName(java.lang.String, org.springframework.core.MethodParameter, org.springframework.web.server.ServerWebExchange) delegates to by default.

5.0

Method Detail

resolveArgumentValue

public java.util.Optional<java.lang.Object> resolveArgumentValue(MethodParameter parameter,
                                                                 BindingContext bindingContext,
                                                                 ServerWebExchange exchange)

Description copied from interface: SyncHandlerMethodArgumentResolver

Resolve the method argument value synchronously returning an optional value.

Specified by:

resolveArgumentValue in interface SyncHandlerMethodArgumentResolver

Parameters:

parameter - the method parameter

bindingContext - the binding context to use

exchange - the current exchange

Returns:

the resolved value if any

resolveName

protected <any> resolveName(java.lang.String name,
                            MethodParameter parameter,
                            ServerWebExchange exchange)

Description copied from class: AbstractNamedValueArgumentResolver

Resolve the given parameter type and value name into an argument value.

Specified by:

resolveName in class AbstractNamedValueArgumentResolver

Parameters:

name - the name of the value being resolved

parameter - the method parameter to resolve to an argument value (pre-nested in case of a Optional declaration)

exchange - the current exchange

Returns:

the resolved argument (may be null)

resolveNamedValue

protected abstract java.util.Optional<java.lang.Object> resolveNamedValue(java.lang.String name,
                                                                          MethodParameter parameter,
                                                                          ServerWebExchange exchange)

An abstract method for synchronous resolution of method argument values that sub-classes must implement.

Parameters:

name - the name of the value being resolved

parameter - the method parameter to resolve to an argument value (pre-nested in case of a Optional declaration)

exchange - the current exchange

Returns:

the resolved argument value, if any
