给我编写一个房屋信息管理系统需要使用javaweb，需要有房屋管理功能以及用户管理功能

好的，为您编写一个房屋信息管理系统，使用JavaWeb，并包括房屋管理功能和用户管理功能。以下是一个简单的示例代码：

// House.java
public class House {
    private String houseId;
    private String address;
    private double price;

    // 构造函数、getters和setters省略
}

// User.java
public class User {
    private String userId;
    private String username;
    private String password;

    // 构造函数、getters和setters省略
}

// HouseManager.java
public class HouseManager {
    private List<House> houses;

    public HouseManager() {
        houses = new ArrayList<>();
    }

    public void addHouse(House house) {
        houses.add(house);
    }

    public void removeHouse(String houseId) {
        for (House house : houses) {
            if (house.getHouseId().equals(houseId)) {
                houses.remove(house);
                break;
            }
        }
    }

    public List<House> getAllHouses() {
        return houses;
    }
}

// UserManager.java
public class UserManager {
    private List<User> users;

    public UserManager() {
        users = new ArrayList<>();
    }

    public void addUser(User user) {
        users.add(user);
    }

    public void removeUser(String userId) {
        for (User user : users) {
            if (user.getUserId().equals(userId)) {
                users.remove(user);
                break;
            }
        }
    }

    public User getUserById(String userId) {
        for (User user : users) {
            if (user.getUserId().equals(userId)) {
                return user;
            }
        }
        return null;
    }
}

// MainServlet.java (JavaWeb的Servlet)
public class MainServlet extends HttpServlet {
    private HouseManager houseManager;
    private UserManager userManager;

    public void init() {
        houseManager = new HouseManager();
        userManager = new UserManager();
    }

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String action = request.getParameter("action");

        if (action.equals("addHouse")) {
            String houseId = request.getParameter("houseId");
            String address = request.getParameter("address");
            double price = Double.parseDouble(request.getParameter("price"));

            House house = new House(houseId, address, price);
            houseManager.addHouse(house);

            response.sendRedirect("house.jsp");
        } else if (action.equals("removeHouse")) {
            String houseId = request.getParameter("houseId");
            houseManager.removeHouse(houseId);

            response.sendRedirect("house.jsp");
        } else if (action.equals("addUser")) {
            String userId = request.getParameter("userId");
            String username = request.getParameter("username");
            String password = request.getParameter("password");

            User user = new User(userId, username, password);
            userManager.addUser(user);

            response.sendRedirect("user.jsp");
        } else if (action.equals("removeUser")) {
            String userId = request.getParameter("userId");
            userManager.removeUser(userId);

            response.sendRedirect("user.jsp");
        }
    }
}

这只是一个简单的示例，您可以根据具体需求进行扩展和完善。同时，您还需要编写相应的JSP页面来展示房屋和用户的信息，以及与Servlet进行交互。

希望以上示例能帮助到您，如果有任何问题，请随时告诉我。
