Class AbstractCookieValueMethodArgumentResolver

java.lang.Object

org.springframework.web.method.annotation.AbstractNamedValueMethodArgumentResolver

org.springframework.web.method.annotation.AbstractCookieValueMethodArgumentResolver

All Implemented Interfaces:

HandlerMethodArgumentResolver

Direct Known Subclasses:

ServletCookieValueMethodArgumentResolver

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 @CookieValue is 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 WebDataBinder may be invoked to apply type conversion to the resolved cookie value.

Constructor Detail

AbstractCookieValueMethodArgumentResolver

public AbstractCookieValueMethodArgumentResolver(ConfigurableBeanFactory beanFactory)

Parameters:

beanFactory - a bean factory to use for resolving ${...} placeholder and #{...} SpEL expressions in default values; or null if default values are not expected to contain expressions

Method Detail

supportsParameter

public boolean supportsParameter(MethodParameter parameter)

Description copied from interface: HandlerMethodArgumentResolver

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

createNamedValueInfo

protected AbstractNamedValueMethodArgumentResolver.NamedValueInfo createNamedValueInfo(MethodParameter parameter)

Description copied from class: AbstractNamedValueMethodArgumentResolver

Create the AbstractNamedValueMethodArgumentResolver.NamedValueInfo object for the given method parameter. Implementations typically retrieve the method annotation by means of MethodParameter.getParameterAnnotation(Class).

Specified by:

createNamedValueInfo in class AbstractNamedValueMethodArgumentResolver

Parameters:

parameter - the method parameter

Returns:

the named value information

handleMissingValue

protected void handleMissingValue(java.lang.String name,
                                  MethodParameter parameter)
                           throws ServletRequestBindingException

Description copied from class: 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.

Specified by:

handleMissingValue in class AbstractNamedValueMethodArgumentResolver

Parameters:

name - the name for the value

parameter - the method parameter

Throws:

ServletRequestBindingException
