Modifier and Type	Method	Description
`Object`	`resolveArgument(MethodParameter parameter, ModelAndViewContainer mavContainer, NativeWebRequest webRequest, WebDataBinderFactory binderFactory)`	Resolves a method parameter into an argument value from a given request.
`boolean`	`supportsParameter(MethodParameter parameter)`	Whether the given method parameter is supported by this resolver.

```
boolean supportsParameter(MethodParameter parameter)
```
    Whether the given method parameter is supported by this resolver.
    Parameters:
    parameter - the method parameter to check
    Returns:
    true if this resolver supports the supplied parameter; false otherwise

                throws Exception
```
    Resolves a method parameter into an argument value from a given request. A ModelAndViewContainer provides access to the model for the request. A WebDataBinderFactory provides a way to create a WebDataBinder instance when needed for data binding and type conversion purposes.
    Parameters:
    parameter - the method parameter to resolve. This parameter must have previously been passed to supportsParameter(org.springframework.core.MethodParameter) which must have returned true.
    mavContainer - the ModelAndViewContainer for the current request
    webRequest - the current request
    binderFactory - a factory for creating WebDataBinder instances
    Returns:
    the resolved argument value, or null if not resolvable
    Throws:
    Exception - in case of errors with the preparation of argument values
