如何使用spring webflux中的对象映射器以非阻塞方式将Object转换为Map

import org.springframework.http.MediaType;
import org.springframework.http.codec.json.Jackson2JsonDecoder;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.reactive.function.BodyInserters;
import org.springframework.web.reactive.function.server.ServerRequest;
import org.springframework.web.reactive.function.server.ServerResponse;
import reactor.core.publisher.Mono;

@RestController
public class MyController {

    private final ObjectMapper objectMapper;

    public MyController(ObjectMapper objectMapper) {
        this.objectMapper = objectMapper;
    }

    @GetMapping("/convert")
    public Mono<ServerResponse> convertObjectToMap(ServerRequest request) {
        Mono<Object> objectMono = request.bodyToMono(Object.class);
        return objectMono.flatMap(object -> {
            byte[] bytes = objectMapper.writeValueAsBytes(object);
            Map<String, Object> map = objectMapper.readValue(bytes, new TypeReference<Map<String, Object>>() {});
            return ServerResponse.ok()
                    .contentType(MediaType.APPLICATION_JSON)
                    .body(BodyInserters.fromValue(map));
        });
    }
}
