WebArgumentResolver

Class Overview

SPI for resolving custom arguments for a specific handler method parameter. Typically implemented to detect special parameter types, resolving well-known argument values for them.

A typical implementation could look like as follows:

 public class MySpecialArgumentResolver implements WebArgumentResolver {

   public Object resolveArgument(MethodParameter methodParameter, NativeWebRequest webRequest) {
     if (methodParameter.getParameterType().equals(MySpecialArg.class)) {
       return new MySpecialArg("myValue");
     }
     return UNRESOLVED;
   }
 }
