类 MatrixParamParameterResolvingStrategy

java.lang.Object

cn.taketoday.web.bind.resolver.AbstractNamedValueResolvingStrategy

cn.taketoday.web.bind.resolver.MatrixParamParameterResolvingStrategy

所有已实现的接口:

ParameterResolvingStrategy

public class MatrixParamParameterResolvingStrategy
extends AbstractNamedValueResolvingStrategy

Resolves arguments annotated with @MatrixParam.

If the method parameter is of type Map it will by resolved by MatrixParamMapParameterResolvingStrategy instead unless the annotation specifies a name in which case it is considered to be a single attribute of type map (vs multiple attributes collected in a map).

resolveName

@Nullable
protected Object resolveName(String name,
 ResolvableMethodParameter resolvable,
 RequestContext request)
                      throws Exception

从类复制的说明: AbstractNamedValueResolvingStrategy

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

指定者:

resolveName 在类中 AbstractNamedValueResolvingStrategy

参数:

name - the name of the value being resolved

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

request - the current request context

返回:

the resolved argument (may be null)

抛出:

Exception - in case of errors

handleMissingValue

protected void handleMissingValue(String name,
 cn.taketoday.core.MethodParameter parameter)
                           throws RequestBindingException

从类复制的说明: AbstractNamedValueResolvingStrategy

Invoked when a named value is required, but AbstractNamedValueResolvingStrategy.resolveName(String, ResolvableMethodParameter, RequestContext) returned null and there is no default value. Subclasses typically throw an exception in this case.

覆盖:

handleMissingValue 在类中 AbstractNamedValueResolvingStrategy

参数:

name - the name for the value

parameter - the method parameter

抛出:

RequestBindingException

从类复制的说明: AbstractNamedValueResolvingStrategy

Invoked when a named value is present but becomes null after conversion.

覆盖:

handleMissingValueAfterConversion 在类中 AbstractNamedValueResolvingStrategy

参数:

name - the name for the value

parameter - the method parameter

request - the current request

抛出:

Exception
