I am implementing MethodInterceptor to translate method call to rest api call, so I need translate method.getGenericReturnType() to ParameterizedTypeReference for ResponseEntity, Here is my hack:

new ParameterizedTypeReference<Object>() {
     @Override
     public Type getType() {
          return method.getGenericReturnType();
     }
}

I wish spring provide such as:

public static ParameterizedTypeReference<?> from(Type type){
     return new ParameterizedTypeReference<Object>() {
          @Override
          public Type getType() {
               return type;
          }
     };
}

Backported to: 4.3.12
