''' Result.class return error

can how i use generics in this case?

Answer 1

Since Spring doesn't know about the generic type it deserializes any unknown type to LinkedHashMap.So use ParameterizedTypeReference to deserialize the json to the exact type of Result. The ParameterizedTypeReference capture the generic type and retain it at runtime.

Mono<Result<Lead>> result = webClient
    .get()
    .uri("/leads?page="+page)
    .header(HttpHeaders.AUTHORIZATION,"Bearer " + tocken)
   .retrieve().bodyToMono(new ParameterizedTypeReference<Result<Lead>>(){
    });;
