使用Java开发仓库管理系统的库存分布分析功能

// 数据访问层接口
public interface InventoryDAO {
  List<Inventory> getInventoryByProduct(String productName);
  List<Inventory> getInventoryByWarehouse(String warehouseName);
}

// 数据访问层实现类
public class InventoryDAOImpl implements InventoryDAO {
  // 实现获取库存记录的方法
  public List<Inventory> getInventoryByProduct(String productName) {
    // TODO: 查询数据库，返回符合条件的库存记录
  }

  public List<Inventory> getInventoryByWarehouse(String warehouseName) {
    // TODO: 查询数据库，返回符合条件的库存记录
  }
}

// 业务逻辑层
public class InventoryService {
  private InventoryDAO inventoryDAO;

  public InventoryService() {
    this.inventoryDAO = new InventoryDAOImpl();
  }

  public List<InventoryDistribution> calculateInventoryDistribution(String productName) {
    List<Inventory> inventoryList = inventoryDAO.getInventoryByProduct(productName);

    // TODO: 实现根据库存记录计算库存分布信息的逻辑

    return inventoryDistributionList;
  }

  public double getProductDistribution(String productName, String warehouseName) {
    List<Inventory> inventoryList = inventoryDAO.getInventoryByWarehouse(warehouseName);

    // TODO: 实现根据库存记录计算某个产品在某个仓库中的占比的逻辑

    return productDistribution;
  }
}

// 用户界面
public class InventoryManagementUI {
  private InventoryService inventoryService;

  public InventoryManagementUI() {
    this.inventoryService = new InventoryService();
  }

  public void analyzeInventoryDistribution(String productName) {
    List<InventoryDistribution> inventoryDistributionList = inventoryService.calculateInventoryDistribution(productName);

    // TODO: 实现展示库存分布分析结果的逻辑
  }
}

public class Main {
  public static void main(String[] args) {
    InventoryManagementUI ui = new InventoryManagementUI();
    ui.analyzeInventoryDistribution("Product A");
  }
}
