我是webflux的新手，我正在尝试转换以下代码：

@Getter
public class Stock {
    private int value;
    private String productNumber;
    public Stock(int value, String productNumber){
        this.value = value;
        this.productNumber = productNumber;
    }
}

@Getter
public class StockResponse {
    private int value;
    private String productNumber;
    public StockResponse(int value, String productNumber){
        this.value = value;
        this.productNumber = productNumber;
    }
    public StockResponse(Stock stock){
        this.value = stock.getValue();
        this.productNumber = stock.getProductNumber();
    }

    public void add(int value){
        this.value += value;
    }
    
}

public List<StockResponse> findStockResponsesDetailsAndTotal() {
    List<StockResponse> stocksResponses = new ArrayList();
    List<Stock> stocks = stockRepository.findAll();
    StockResponse total = new StockResponse(0, "Total");
    stocks.forEach(stock -> {
        total.add(stock.getValue());
        stocksResponses.add(new StockResponse(stock));
    });
    stocksResponses.add(total);
    return stocksResponses;
}

下面是我的代码：

stockRepository.findAll()
  .map(StockResponse::convert)

我有点迷失了关于“总”，我知道，我可以做一个减少通量，但我会失去所有的细节，这样做
