基于Java纯净水供应店信息管理平台设计与实现，开发平台为IntelliJ IDEA。要求实现功能1：纯净水信息管理功能，功能2：会员管理功能，功能3：纯净水销售。写出实现功能的代码

好的，下面是基于Java的纯净水供应店信息管理平台与实现代码示例，实现三个功能：

1.净水信息管理功能：

（）纯净水Bean代码：

public class PureWater {
    private int id;
 private String name;
    String brand;
    private String;
    private double price;

    // 省getters和setters方法
}

（2）纯净水DAO代码：

public interface PureWaterDao {
    // 添加纯净水
    int addPureWater(PureWater pureWater);

    // 删除纯净水
    int deletePureWater(int id);

    // 修改纯净水
    int updatePureWater(PureWater pureWater);

    // 查询所有纯净水
    List<PureWater> getAllPureWater();

    // 根据id查询纯净水
    PureWater getPureWaterById(int id);

    // 修改库存
    int updateInventory(int id, int count);
}

（3）纯净水Service代码：

@Service
public class PureWaterService {
    @Autowired
    private PureWaterDao pureWaterDao;

    // 添加纯净水
    public int addPureWater(PureWater pureWater) {
        return pureWaterDao.addPureWater(pureWater);
    }

    // 删除纯净水
    public int deletePureWater(int id) {
        return pureWaterDao.deletePureWater(id);
    }

    // 修改纯净水
    public int updatePureWater(PureWater pureWater) {
        return pureWaterDao.updatePureWater(pureWater);
    }

    // 查询所有纯净水
    public List<PureWater> getAllPureWater() {
        return pureWaterDao.getAllPureWater();
    }

    // 根据id查询纯净水
    public PureWater getPureWaterById(int id) {
        return pureWaterDao.getPureWaterById(id);
    }

    // 修改库存
    public int updateInventory(int id, int count) {
        return pureWaterDao.updateInventory(id, count);
    }
}

（4）纯净水Controller代码：

@Controller
public class PureWaterController {
    @Autowired
    private PureWaterService pureWaterService;

    // 转到纯净水信息管理页面
    @RequestMapping("/pureWater")
    public String toPureWater(HttpSession session) {
        List<PureWater> pureWaters = pureWaterService.getAllPureWater();
        session.setAttribute("pureWaters", pureWaters);
        return "pureWater";
    }

    // 添加纯净水
    @RequestMapping("/addPureWater")
    @ResponseBody
    public String addPureWater(PureWater pureWater) {
        int result = pureWaterService.addPureWater(pureWater);
        if (result > 0) {
            return "success";
        } else {
            return "fail";
        }
    }

    // 删除纯净水
    @RequestMapping("/deletePureWater")
    @ResponseBody
    public String deletePureWater(int id) {
        int result = pureWaterService.deletePureWater(id);
        if (result > 0) {
            return "success";
        } else {
            return "fail";
        }
    }

    // 修改纯净水
    @RequestMapping("/updatePureWater")
    @ResponseBody
    public String updatePureWater(PureWater pureWater) {
        int result = pureWaterService.updatePureWater(pureWater);
        if (result > 0) {
            return "success";
        } else {
            return "fail";
        }
    }

    // 修改库存
    @RequestMapping("/updateInventory")
    @ResponseBody
    public String updateInventory(int id, int count) {
        int result = pureWaterService.updateInventory(id, count);
        if (result > 0) {
            return "success";
        } else {
            return "fail";
        }
    }
}

2. 会员管理功能：

（1）会员Bean代码：

public class Member {
    private int id;
    private String name;
    private String phone;
    private String address;
    private int points;

    // 修改会员
    int updateMember(Member member);

    // 查询所有会员
    List<Member> getAllMember();

    // 根据id查询会员
    Member getMemberById(int id);

    // 修改积分
    int updatePoints(int id, int points);
}

（3）会员Service代码：

@Service
public class MemberService {
    @Autowired
    private MemberDao memberDao;

    // 添加会员
    public int addMember(Member member) {
        return memberDao.addMember(member);
    }

    // 删除会员
    public int deleteMember(int id) {
        return memberDao.deleteMember(id);
    }

    // 修改会员
    public int updateMember(Member member) {
