BooksManagementSystem(图书管理系统)

一、数据库

  1. 创建数据库

    -- 添加数据库
    create database if not exists bms;
  2. 创建表

    -- 创建user表
    create table `user`(
    `id` int(11) not null auto_increment comment '学号',
    `username` varchar(20) default null,
    `password` varchar(20) default null,
    primary key(`id`)
    )ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
    -- 创建一个表
    create table `book`(
    `bookID` int(11) not null auto_increment comment '图书编号',
    `bookName` varchar(20) default null comment '图书名称',
    `bookPublishing` varchar(20) default null comment '图书出版社',
    `bookAuthor` varchar(20) default null comment '图书作者',
    primary key(`bookID`)
    )ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
  3. 插入数据

    -- 表中添加数据
    insert into `book` values(1,'国学的读与做','华夏出版社','潘志坚,江洋 著');
    insert into `book` values
    (null,'浮生六记(软精装)','江苏人民出版社','[清] 沈复 著,霍振国 译'),
    (null,'标准日语临摹字帖','	江苏凤凰科学技术出版社','易人外语编辑部 编');

二、搭建maven环境

  1. 搭建框架:dao、Filter、pojo、service、servlet、utils、app

  2. pom.xml中配置依赖

    <?xml version="1.0" encoding="UTF-8"?>
    
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </dependency>
    
      </dependencies>
    </project>
  3. web.xml修改头部

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
              http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
             version="4.0">
      <display-name>Archetype Created Web Application</display-name>
      <!--    设置欢迎页面-->
      <welcome-file-list>
        <welcome-file>login.jsp</welcome-file>
      </welcome-file-list>
    </web-app>
  4. 配置tomcat,并运行

  5. 导入resources配置文件

    driver=com.mysql.jdbc.Driver
    url=jdbc:mysql://localhost:3306/bms?useUnicode=true&characterEncoding=utf8&useSSL=true
    username=root
    password=123456
  6. 编写过滤器Filter

    package com.lyh.Filter;
    
    import javax.servlet.*;
    import javax.servlet.annotation.WebFilter;
    import java.io.IOException;
    //处理乱码问题
    @WebFilter("/*")
    public class CharacterFilter implements Filter {
        @Override
        public void init(FilterConfig filterConfig) throws ServletException {
    
        }
    
        @Override
        public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
            servletRequest.setCharacterEncoding("UTF-8");
            filterChain.doFilter(servletRequest,servletResponse);
        }
    
        @Override
        public void destroy() {
    
        }
    }

三、编写pojo实体类

  1. user实体类

    package com.lyh.pojo;
    
    public class User {
        private Integer id;
        private String userName;
        private String passWord;
    
        public User() {
        }
    
        public User(Integer id, String userName, String passWord) {
            this.id = id;
            this.userName = userName;
            this.passWord = passWord;
        }
    
        public Integer getId() {
            return id;
        }
    
        public void setId(Integer id) {
            this.id = id;
        }
    
        public String getUserName() {
            return userName;
        }
    
        public void setUserName(String userName) {
            this.userName = userName;
        }
    
        public String getPassWord() {
            return passWord;
        }
    
        public void setPassWord(String passWord) {
            this.passWord = passWord;
        }
    
        @Override
        public String toString() {
            return "user{" +
                    "id=" + id +
                    ", userName='" + userName + '\'' +
                    ", passWord='" + passWord + '\'' +
                    '}';
        }
    }
  2. book实体类

    package com.lyh.pojo;
    
    public class Book {
        private Integer bookID;
        private String bookName;
        private String bookPublishing;
        private String bookAuthor;
    
        public Book() {
        }
    
        public Book(Integer bookID, String bookName, String bookPublishing, String bookAuthor) {
            this.bookID = bookID;
            this.bookName = bookName;
            this.bookPublishing = bookPublishing;
            this.bookAuthor = bookAuthor;
        }
    
        public Integer getBookID() {
            return bookID;
        }
    
        public void setBookID(Integer bookID) {
            this.bookID = bookID;
        }
    
        public String getBookName() {
            return bookName;
        }
    
        public void setBookName(String bookName) {
            this.bookName = bookName;
        }
    
        public String getBookPublishing() {
            return bookPublishing;
        }
    
        public void setBookPublishing(String bookPublishing) {
            this.bookPublishing = bookPublishing;
        }
    
        public String getBookAuthor() {
            return bookAuthor;
        }
    
        public void setBookAuthor(String bookAuthor) {
            this.bookAuthor = bookAuthor;
        }
    
        @Override
        public String toString() {
            return "user{" +
                    "bookID=" + bookID +
                    ", bookName='" + bookName + '\'' +
                    ", bookPublishing='" + bookPublishing + '\'' +
                    ", bookAuthor='" + bookAuthor + '\'' +
                    '}';
        }
    }

四、编写dao层

  1. 编写jdbc连接类(也就是BaseDao)并测试

    package com.lyh.dao;
    
    import com.lyh.pojo.User;
    import org.junit.jupiter.api.Test;
    
    import java.io.IOException;
    import java.io.InputStream;
    import java.sql.*;
    import java.util.Properties;
    
    /**
     * 连接数据库工具类
     */
    public class BaseDao {
        private static String driver;
        private static String url;
        private static String username;
        private static String password;
    
        private Connection connection;
        private ResultSet resultSet;
        private PreparedStatement preparedStatement;
    
        //静态代码块,类加载的时候就初始化了
        static {
            Properties properties = new Properties();
            /*
             BaseDao.class获取当前工具类的Class文件
             getClassLoader()获取该Class文件的类装载器
             getResourceAsStream(“db.properties”)通过类加载器的方法加载资源,返回的是字节流
             使用Properties类是为了可以从.properties属性文件对应的文件输入流中,
             加载属性列表到Properties类对象,
             然后通过getProperty方法用指定的键在此属性列表中搜索属性
             */
            //通过类加载器读取对应的资源
            InputStream resourceAsStream = BaseDao.class.getClassLoader().getResourceAsStream("db.properties");
            try {
                properties.load(resourceAsStream);
            } catch (IOException e) {
                e.printStackTrace();
            }
            driver = properties.getProperty("driver");
            url = properties.getProperty("url");
            username = properties.getProperty("username");
            password = properties.getProperty("password");
            try {
                //加载驱动
                Class.forName(driver);
            } catch (ClassNotFoundException e) {
                e.printStackTrace();
            }
        }
    
        //创建连接
        private void getconnection() {
            try {
                connection = DriverManager.getConnection(url, username, password);
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
        //执行sql语句
    
        /**
         * Object...意思就是你写一个参数,他读取一个参数,写两个读取两个
         */
        //增删改
        public int executeUpdate(String sql, Object... objects) {
            //获取连接
            getconnection();
            try {
                //select * from user where name=? and pwd=?;
                preparedStatement = connection.prepareStatement(sql);
                if (objects != null) {
                    for (int i = 0; i < objects.length; i++) {
                        preparedStatement.setObject(i + 1, objects[i]);
                    }
                }
                int i = preparedStatement.executeUpdate();
                //关闭资源
                close();
                return i;
            } catch (SQLException e) {
                e.printStackTrace();
            }
            return -1;
        }
        //查询
        public ResultSet executeQuery(String sql,Object...objects){
            //获取连接
            getconnection();
            try {
                preparedStatement = connection.prepareStatement(sql);
                if (objects!=null){
                    for (int i = 0; i < objects.length; i++) {
                        preparedStatement.setObject(i+1,objects[i]);
                    }
                }
                resultSet = preparedStatement.executeQuery();
                return resultSet;
            } catch (SQLException e) {
                e.printStackTrace();
            }
            return null;
        }
    
        //关闭连接
        public void close() {
    
            try {
                if (resultSet != null) {
                    resultSet.close();
                }
                if (preparedStatement != null) {
                    preparedStatement.close();
                }
                if (connection != null) {
                    connection.close();
                }
            } catch (SQLException e) {
                e.printStackTrace();
                System.out.println("失败");
            }
    
        }
    //    @Test
    //    public void t1(){
    //        User user = new User(null,"王子恩","123123");
    //        String sql="insert into `user`(username,password) values('"+user.getUserName()+"','"+user.getPassWord()+"');";
    //        int update = executeUpdate(sql);
    //        if (update>0){
    //            System.out.println("添加成功");
    //        }
    //    }
    
    }
  2. 编写UserDao接口

    package com.lyh.dao.user;
    
    import com.lyh.pojo.User;
    
    public interface UserDao {
        //添加用户
        boolean addUser(User user);
        //查询用户信息(登录)
        User Login(User user);
    }
  3. 编写UserDaoImpl实现类

    import java.sql.SQLException;
    
    public class UserDaoImpl extends BaseDao implements UserDao {
        @Override
        public boolean addUser(User user) {
            String sql="insert into `user`(username,password) values(?,?);";
            int i = this.executeUpdate(sql, user.getUserName(), user.getPassWord());
            if (i<=0){
                return false;
            }
            return true;
        }
    
        @Override
        public User Login(User user) {
            String sql="select * from user where username=? and password=?";
            ResultSet resultSet = this.executeQuery(sql, user.getUserName(), user.getPassWord());
            System.out.println(sql);
            try {
                User user1=null;
                if (resultSet.next()){
                    user1=new User(resultSet.getInt(1),resultSet.getString(2),resultSet.getString(3));
    
                }

    package com.lyh.dao.book;
    
    import com.lyh.pojo.Book;
    
    import java.util.List;
    
    /**
     * 图书实例化接口
     */
    public interface BookDao {
        //查询图书
        List<Book> listBookByName(String bookName);
        //添加图书
        int addBook(Book book);
        //修改图书

        }
    
        @Override
        public int delBook(Integer bookID) {
            String sql="delete from book where bookID=?;";
            return executeUpdate(sql,bookID);
        }
    }

五、编写service层

  1. 编写UserService接口

    package com.lyh.service;
    
    import com.lyh.pojo.User;
    
    public interface UserService {
        /**
         * 用户注册

    import com.lyh.pojo.User;
    
    public class UserServiceImpl implements UserService {
        private UserDao userDao=new UserDaoImpl();
        @Override
        public boolean doRegedit(User user) {

        }
    
        @Override
        public User doLogin(User user) {
            return userDao.Login(user);
        }
    }
  3. 编写BookService

    package com.lyh.service;
    
    import com.lyh.pojo.Book;
    
    import java.util.List;
    
    public interface BookService {
        //查询图书
        List<Book> listBookByName(String bookName);
        //添加图书
        int addBook(Book book);
        //修改图书
        int updateBook(Book book);
        //删除图书
        int delBook(Integer bookID);
    }
  4. 编写BookServiceImpl

    package com.lyh.service;
    
    import com.lyh.dao.book.BookDao;
    import com.lyh.dao.book.BookDaoImpl;
    import com.lyh.pojo.Book;
    
    import java.util.List;
    
    public class BookServiceImpl implements BookService{
        private BookDao bookDao=new BookDaoImpl();
        @Override
        public List<Book> listBookByName(String bookName) {
            return bookDao.listBookByName(bookName);
        }
    
        @Override
        public int addBook(Book book) {
            return bookDao.addBook(book);
        }
    
        @Override
        public int updateBook(Book book) {
            return bookDao.updateBook(book);
        }
    
        @Override
        public int delBook(Integer bookID) {
            return bookDao.delBook(bookID);
        }
    }

六、编写servlet层

  1. 编写LoginServlet类(登录):从页面上抓取数据添加到数据库中;往service层传递数据

    package com.lyh.servlet;
    
    import com.lyh.pojo.User;
    import com.lyh.service.UserService;
    import com.lyh.service.UserServiceImpl;

    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;
    
    @WebServlet("/doLogin")
    public class LoginServlet extends HttpServlet {
        private UserService userService=new UserServiceImpl();
        @Override
        protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
            String username = req.getParameter("username");
            String password = req.getParameter("password");
            User user = new User(null, username, password);
            User user1 = userService.doLogin(user);
            if (user1!=null){
                req.getSession().setAttribute("user",user);
                resp.sendRedirect("index.jsp");
            }else {
                resp.sendRedirect("error.jsp");
            }
        }
    
        @Override
        protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
            doGet(req, resp);
        }
    }
  2. 编写RegeditServlet类(注册):从页面上抓取数据添加到数据库中;往service层传递数据

    package com.lyh.servlet;
    
    import com.lyh.pojo.User;
    import com.lyh.service.UserService;
    import com.lyh.service.UserServiceImpl;
    
    import javax.servlet.ServletException;

    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;
    
    @WebServlet("/doRegedit")
    public class RegeditServlet extends HttpServlet {
        private UserService userService=new UserServiceImpl();
        @Override
        protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
            String username = req.getParameter("username");
            String password = req.getParameter("password");
            User user = new User(null,username,password);
            boolean b = userService.doRegedit(user);
            if (b){
                resp.sendRedirect("login.jsp");
            }else {
                resp.sendRedirect("error.jsp");
            }
        }
    
        @Override
        protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
            doGet(req, resp);
        }
    }
  3. 编写AddBookServlet类(添加):从页面上抓取数据添加到数据库中:往service层传递数据

    package com.lyh.servlet;
    
    import com.lyh.pojo.Book;
    import com.lyh.service.BookService;
    import com.lyh.service.BookServiceImpl;
    
    import javax.servlet.ServletException;
    import javax.servlet.annotation.WebServlet;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;
    
    /**
     * 添加图书
     */
    @WebServlet("/addBook")
    public class AddBookServlet extends HttpServlet {
        private BookService bookService=new BookServiceImpl();
        @Override
        protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
            String bookName = req.getParameter("bookName");
            String bookPublishing = req.getParameter("bookPublishing");
            String bookAuthor = req.getParameter("bookAuthor");
            Book book = new Book(null,bookName,bookPublishing,bookAuthor);
            int i = bookService.addBook(book);
            if (i>0){
                System.out.println("添加成功");
                resp.sendRedirect("HomePage.jsp");
            }else {
                resp.sendRedirect("error.jsp");
            }
        }
    
        @Override
        protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
            doGet(req, resp);
        }
    }
  4. 编写DelBookServlet类(删除):根据页面session中活得图书编号然后根据编号删除这一类

    package com.lyh.servlet;
    
    import com.lyh.service.BookService;
    import com.lyh.service.BookServiceImpl;
    
    import javax.servlet.ServletException;
    import javax.servlet.annotation.WebServlet;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;
    
    @WebServlet("/delBook")
    public class DelBookServlet extends HttpServlet {
        private BookService bookService=new BookServiceImpl();
        @Override
        protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
            String bookID = req.getParameter("bookID");
            int i = bookService.delBook(Integer.parseInt(bookID));
            if (i>0){
                System.out.println("删除成功");
                resp.sendRedirect("HomePage.jsp");
            }else {
                System.out.println("删除失败");
                resp.sendRedirect("error.jsp");
            }
        }
    
        @Override
        protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
            doGet(req, resp);
        }
    }
  5. 编写UpdateServlet类(修改):从页面上抓取数据添加到数据库中:往service层传递数据

    package com.lyh.servlet;
    
    import com.lyh.pojo.Book;
    import com.lyh.service.BookService;
    import com.lyh.service.BookServiceImpl;
    
    import javax.servlet.ServletException;
    import javax.servlet.annotation.WebServlet;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;
    
    @WebServlet("/UpdateBook")
    public class UpdateServlet extends HttpServlet {
        private BookService bookService=new BookServiceImpl();
        @Override
        protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
            String bookID = req.getParameter("bookID");
            String bookName = req.getParameter("bookName");
            String bookPublishing = req.getParameter("bookPublishing");
            String bookAuthor = req.getParameter("bookAuthor");
            Book book = new Book();
            book.setBookID(Integer.valueOf(bookID));
            book.setBookName(bookName);
            book.setBookPublishing(bookPublishing);
            book.setBookAuthor(bookAuthor);
            int i = bookService.updateBook(book);
            if (i>0){
                System.out.println("修改成功");
                resp.sendRedirect("HomePage.jsp");
            }else {
                resp.sendRedirect("error.jsp");
            }
        }
    
        @Override
        protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
            doGet(req, resp);
        }
    }
  6. 编写ListBookFilter过滤器(过滤页面直接显示数据库中的数据到页面,每次访问都会过滤)

    package com.lyh.Filter;
    
    import com.lyh.pojo.Book;
    import com.lyh.service.BookService;
    import com.lyh.service.BookServiceImpl;
    
    import javax.servlet.*;
    import javax.servlet.annotation.WebFilter;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpSession;
    import java.io.IOException;
    import java.util.List;
    
    @WebFilter("/HomePage.jsp")
    public class ListBookFilter implements Filter {
        private BookService bookService=new BookServiceImpl();
        @Override
        public void init(FilterConfig filterConfig) throws ServletException {
    
    
        }
    
        @Override
        public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
            HttpSession session = ((HttpServletRequest) servletRequest).getSession();
            List<Book> books = bookService.listBookByName(null);
            session.setAttribute("bookList",books);
            filterChain.doFilter(servletRequest,servletResponse);
        }
    
        @Override
        public void destroy() {
    
        }
    }

七、前端页面
