Constructor Detail

ArrayArgumentResolver

public ArrayArgumentResolver(boolean useDefaultResolution)

Create a new CustomRequestParamMethodArgumentResolver instance.

Parameters:

useDefaultResolution - in default resolution mode a method argument that is a simple type, as defined in BeanUtils.isSimpleProperty(java.lang.Class<?>), is treated as a request parameter even if it isn't annotated, the request parameter name is derived from the method parameter name.

ArrayArgumentResolver

public ArrayArgumentResolver(@Nullable
                             org.springframework.beans.factory.config.ConfigurableBeanFactory beanFactory,
                             boolean useDefaultResolution)

Create a new CustomRequestParamMethodArgumentResolver instance.

Parameters:

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

useDefaultResolution - in default resolution mode a method argument that is a simple type, as defined in BeanUtils.isSimpleProperty(java.lang.Class<?>), is treated as a request parameter even if it isn't annotated, the request parameter name is derived from the method parameter name.

Method Detail

supportsParameter

public boolean supportsParameter(org.springframework.core.MethodParameter parameter)

Supports the following:

• @RequestParam-annotated method arguments. This excludes Map params where the annotation does not specify a name. See RequestParamMapMethodArgumentResolver instead for such params.
• Arguments of type MultipartFile unless annotated with @RequestPart.
• Arguments of type Part unless annotated with @RequestPart.
• In default resolution mode, simple type arguments even if not with @RequestParam.
