`protected AbstractNamedValueMethodArgumentResolver.NamedValueInfo`	`createNamedValueInfo(MethodParameter parameter)`	Create the `AbstractNamedValueMethodArgumentResolver.NamedValueInfo` object for the given method parameter.
`protected void`	`handleMissingValue(String name, MethodParameter parameter, Message<?> message)`	Invoked when a value is required, but `AbstractNamedValueMethodArgumentResolver.resolveArgumentInternal(org.springframework.core.MethodParameter, org.springframework.messaging.Message<?>, java.lang.String)` returned `null` and there is no default value.
`protected Object`	`resolveArgumentInternal(MethodParameter parameter, Message<?> message, String name)`	Resolves the given parameter type and value name into an argument value.
`boolean`	`supportsParameter(MethodParameter parameter)`	Whether the given method parameter is supported by this resolver.

    从接口复制的说明: HandlerMethodArgumentResolver
    Whether the given method parameter is supported by this resolver.
    参数:
    parameter - the method parameter to check
    返回:
    true if this resolver supports the supplied parameter; false otherwise
  - createNamedValueInfo
```
protected AbstractNamedValueMethodArgumentResolver.NamedValueInfo createNamedValueInfo(MethodParameter parameter)
```
    从类复制的说明: AbstractNamedValueMethodArgumentResolver
    Create the AbstractNamedValueMethodArgumentResolver.NamedValueInfo object for the given method parameter. Implementations typically retrieve the method annotation by means of MethodParameter.getParameterAnnotation(Class).
    指定者:
    createNamedValueInfo 在类中 AbstractNamedValueMethodArgumentResolver
    参数:
    parameter - the method parameter
    返回:
    the named value information
  - resolveArgumentInternal
```
@Nullable
protected Object resolveArgumentInternal(MethodParameter parameter,
                                         Message<?> message,

    Resolves the given parameter type and value name into an argument value.
    指定者:
    resolveArgumentInternal 在类中 AbstractNamedValueMethodArgumentResolver
    参数:
    parameter - the method parameter to resolve to an argument value
    message - the current request
    name - the name of the value being resolved
    返回:

  - handleMissingValue
```
protected void handleMissingValue(String name,

```
    从类复制的说明: AbstractNamedValueMethodArgumentResolver
    Invoked when a value is required, but AbstractNamedValueMethodArgumentResolver.resolveArgumentInternal(org.springframework.core.MethodParameter, org.springframework.messaging.Message<?>, java.lang.String) returned null and there is no default value. Sub-classes can throw an appropriate exception for this case.
    指定者:
    handleMissingValue 在类中 AbstractNamedValueMethodArgumentResolver
    参数:
    name - the name for the value
    parameter - the target method parameter
    message - the message being processed
