public abstract class AbstractCookieValueMethodArgumentResolver extends AbstractNamedValueMethodArgumentResolver
A base abstract class to resolve method arguments annotated with@CookieValue. Subclasses extract the cookie value from the request.An
@CookieValueis a named value that is resolved from a cookie. It has a required flag and a default value to fall back on when the cookie does not exist.A
WebDataBindermay be invoked to apply type conversion to the resolved cookie value.- 从以下版本开始:

AbstractCookieValueMethodArgumentResolver
public AbstractCookieValueMethodArgumentResolver(@Nullable ConfigurableBeanFactory beanFactory)
Crate a newAbstractCookieValueMethodArgumentResolverinstance.- 参数:
beanFactory- a bean factory to use for resolving ${...} placeholder and #{...} SpEL expressions in default values; ornullif default values are not expected to contain expressions
方法详细资料
supportsParameter
public boolean supportsParameter(MethodParameter parameter)
从接口复制的说明:HandlerMethodArgumentResolverWhether the given method parameter is supported by this resolver.- 参数:
parameter- the method parameter to check- 返回:
trueif this resolver supports the supplied parameter;falseotherwise
createNamedValueInfo
protected AbstractNamedValueMethodArgumentResolver.NamedValueInfo createNamedValueInfo(MethodParameter parameter)
Create theAbstractNamedValueMethodArgumentResolver.NamedValueInfoobject for the given method parameter. Implementations typically retrieve the method annotation by means ofMethodParameter.getParameterAnnotation(Class).- 指定者:
createNamedValueInfo在类中AbstractNamedValueMethodArgumentResolver- 参数:
parameter- the method parameter- 返回:
- the named value information
handleMissingValue
protected void handleMissingValue(String name, MethodParameter parameter) throws ServletRequestBindingException
Invoked when a named value is required, butAbstractNamedValueMethodArgumentResolver.resolveName(String, MethodParameter, NativeWebRequest)returnednulland 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 valueparameter- the method parameter- 抛出:
ServletRequestBindingException
