`protected AbstractNamedValueMethodArgumentResolver.NamedValueInfo`	`createNamedValueInfo(MethodParameter parameter)`	Create the `AbstractNamedValueMethodArgumentResolver.NamedValueInfo` object for the given method parameter.
`protected void`	`handleMissingValue(String name, MethodParameter parameter)`	Invoked when a named value is required, but `AbstractNamedValueMethodArgumentResolver.resolveName(String, MethodParameter, NativeWebRequest)` returned `null` and there is no default value.
`protected Object`	`resolveName(String name, MethodParameter parameter, NativeWebRequest request)`	Resolve 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.

  - supportsParameter
```
public boolean supportsParameter(MethodParameter parameter)
```
    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
  - resolveName
```
protected Object resolveName(String name,
                             MethodParameter parameter,
                             NativeWebRequest request)
```
    从类复制的说明: AbstractNamedValueMethodArgumentResolver
    Resolve the given parameter type and value name into an argument value.
    指定者:
    resolveName 在类中 AbstractNamedValueMethodArgumentResolver
    参数:
    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)
    request - the current request
    返回:
    the resolved argument (may be null)
  - handleMissingValue
```
protected void handleMissingValue(String name,
                                  MethodParameter parameter)
                           throws ServletException
```
    从类复制的说明: AbstractNamedValueMethodArgumentResolver
    Invoked when a named value is required, but AbstractNamedValueMethodArgumentResolver.resolveName(String, MethodParameter, NativeWebRequest) returned null and there is no default value. Subclasses typically throw an exception in this case.
    覆盖:
    handleMissingValue 在类中 AbstractNamedValueMethodArgumentResolver
    参数:
    name - the name for the value
    parameter - the method parameter
    抛出:
    ServletException
