程序包 cn.taketoday.web.service.invoker

类 RequestParamArgumentResolver

java.lang.Object

cn.taketoday.web.service.invoker.AbstractNamedValueArgumentResolver

cn.taketoday.web.service.invoker.RequestParamArgumentResolver

所有已实现的接口:

HttpServiceArgumentResolver

public class RequestParamArgumentResolver
extends AbstractNamedValueArgumentResolver

HttpServiceArgumentResolver for @RequestParam annotated arguments.

When "content-type" is set to "application/x-www-form-urlencoded", request parameters are encoded in the request body. Otherwise, they are added as URL query parameters.

The argument may be:

• Map<String, ?> or MultiValueMap<String, ?> with multiple request parameter and value(s).
• Collection or an array of request parameters.
• An individual request parameter.

Individual request parameters may be Strings or Objects to be converted to String values through the configured ConversionService.

If the value is required but null, IllegalArgumentException is raised. The value is not required if:

• RequestParam.required() is set to false
• RequestParam.defaultValue() provides a fallback value
• The argument is declared as Optional

从以下版本开始:
