- org.springframework.web.method.annotation.ErrorsMethodArgumentResolver

所有已实现的接口:
HandlerMethodArgumentResolver
```
public class ErrorsMethodArgumentResolver
extends Object
implements HandlerMethodArgumentResolver
```
Resolves Errors method arguments.
An Errors method argument is expected to appear immediately after the model attribute in the method signature. It is resolved by expecting the last two attributes added to the model to be the model attribute and its BindingResult.

    参数:
    parameter - the method parameter to check
    返回:
    true if this resolver supports the supplied parameter; false otherwise

```
    从接口复制的说明: HandlerMethodArgumentResolver
    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.
    指定者:
    resolveArgument 在接口中 HandlerMethodArgumentResolver
    参数:
    parameter - the method parameter to resolve. This parameter must have previously been passed to HandlerMethodArgumentResolver.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
    返回:
    the resolved argument value, or null if not resolvable
    抛出:
    Exception - in case of errors with the preparation of argument values
