RequestParam(value: String, name: String, required: Boolean, defaultValue: String)
Annotation which indicates that a method parameter should be bound to a web request parameter.
Supported for annotated handler methods in Servlet and Portlet environments.
If the method parameter type is Map and a request parameter name is specified, then the request parameter value is converted to a Map assuming an appropriate conversion strategy is available.
If the method parameter is java.util.Map or org.springframework.util.MultiValueMap and a parameter name is not specified, then the map parameter is populated with all request parameter names and values.
