所有已实现的接口:
HandlerMethodArgumentResolver, SyncHandlerMethodArgumentResolver
```
public class PathVariableMethodArgumentResolver
extends AbstractNamedValueSyncArgumentResolver
```
Resolves method arguments annotated with @PathVariable.
An @PathVariable is a named value that gets resolved from a URI template variable. It is always required and does not have a default value to fall back on. See the base class AbstractNamedValueMethodArgumentResolver for more information on how named values are processed.
If the method parameter type is Map, the name specified in the annotation is used to resolve the URI variable String value. The value is then converted to a Map via type conversion, assuming a suitable Converter.

修饰符和类型	方法	说明
`protected AbstractNamedValueArgumentResolver.NamedValueInfo`	`createNamedValueInfo(MethodParameter parameter)`	Create the `AbstractNamedValueArgumentResolver.NamedValueInfo` object for the given method parameter.
`protected void`	`handleMissingValue(String name, MethodParameter parameter)`	Invoked when a named value is required, but `AbstractNamedValueArgumentResolver.resolveName(String, MethodParameter, ServerWebExchange)` returned `null` and there is no default value.
`protected void`	`handleResolvedValue(Object arg, String name, MethodParameter parameter, Model model, ServerWebExchange exchange)`	Invoked after a value is resolved.
`protected Object`	`resolveNamedValue(String name, MethodParameter parameter, ServerWebExchange exchange)`	Actually resolve the value synchronously.
`boolean`	`supportsParameter(MethodParameter parameter)`	Whether this resolver supports the given method parameter.

    从接口复制的说明: HandlerMethodArgumentResolver
    Whether this resolver supports the given method parameter.

    从类复制的说明: AbstractNamedValueArgumentResolver
    Create the AbstractNamedValueArgumentResolver.NamedValueInfo object for the given method parameter. Implementations typically retrieve the method annotation by means of MethodParameter.getParameterAnnotation(Class).
    指定者:

```
    从类复制的说明: AbstractNamedValueArgumentResolver
    Invoked when a named value is required, but AbstractNamedValueArgumentResolver.resolveName(String, MethodParameter, ServerWebExchange) returned null and there is no default value. Subclasses typically throw an exception in this case.
    覆盖:
    handleMissingValue 在类中 AbstractNamedValueArgumentResolver
    参数:

    parameter - the method parameter
