article 2025/1/22 14:46:20

1. 生鲜后台管理系统-注册功能

1.1. 注册功能

  （1）创建注册RegisterServlet，接收form表单中的参数。
  （2）service创建一个userService处理业务逻辑。
  （3）RegisterServlet将参数传递给servie层。
  （4）Dao层创建一个userDao操作数据库。
  （5）userService调用dao层userDao将用户注册信息加入到数据库中。
  （6）注册成功后RegisterServlet调用请求转发到login、jsp界面。

1.2. 步骤

在这里插入图片描述

  （1）创建RegisterServlet

package com.zzs.szsd.web;
import com.zzs.szsd.bean.User;
import com.zzs.szsd.service.UserService;
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(name = "RegisterServlet",urlPatterns = "/register")
public class RegisterServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request,
                          HttpServletResponse response)
            throws ServletException, IOException {
        String id = request.getParameter("id");
        String name = request.getParameter("name");
        String password = request.getParameter("password");
        String email = request.getParameter("email");
        User user=new User();
        user.setName(name);
        user.setPassword(password);
        user.setEmail(email);
        UserService userService=new UserService();
        boolean register = userService.register(user);
        if (register) {
           response.sendRedirect(request.getContextPath()+"/login.jsp");
        }else {
            response.setContentType("text/html;charset=utf-8");
            response.getWriter().write("注册失败");
        }

    }
    protected void doGet(HttpServletRequest request,
                         HttpServletResponse response)
            throws ServletException, IOException {
    }
}

  （2）创建UserService

package com.zzs.szsd.service;
import com.zzs.szsd.bean.User;
import com.zzs.szsd.dao.UserDao;
import java.sql.SQLException;
public class UserService {
    /**
     * @method:register 用户注册
     * @params:[name, password, email]
     * @return: boolean
     */
    //1. 判断注册用户是否存在
    public boolean register(User user) {
        boolean register=false;
        UserDao userDao = new UserDao();
        boolean checkUser = userDao.checkUser(user.getName());
        //2. 如果不存在就将用户信息添加到数据库
        if (checkUser) {
             register = userDao.register(user);
        }
        return register;
    }
    /**
     * @method:login 用户登录
     * @params:[name, password]
     * @return: void
     */
    public User login(String name, String password) throws SQLException {
        UserDao userDao=new UserDao();
        User user = userDao.login(name, password);
        return  user;
    }
}

  （3）创建UserDao

package com.zzs.szsd.dao;
import com.mchange.v2.c3p0.ComboPooledDataSource;
import com.zzs.szsd.bean.User;
import org.apache.commons.dbutils.QueryRunner;
import org.apache.commons.dbutils.handlers.BeanHandler;
import java.sql.SQLException;
public class UserDao {
    /**
     * @method:checkUser 检查用户是否存在
     * @params:[name]
     * @return: boolean
     */
    public boolean checkUser(String name){
        try {
            ComboPooledDataSource dataSource=new ComboPooledDataSource();
            QueryRunner queryRunner=new QueryRunner(dataSource);
            String sql="select name from user where name=?";
            User user = queryRunner.query(sql, new BeanHandler<User>(User.class),name);
            //如果没有查询到数据 说明这个用户名没有注册过
            if (user==null) {
                return  true;
            }else {
                return  false;
            }
        } catch (SQLException e) {
            e.printStackTrace();
            return  false;
        }
    }
    /**
     * @method:register 用户注册
     * @params:[name, password, email]
     * @return: boolean
     */
    public boolean register(User user) {
        try {
            ComboPooledDataSource dataSource=new ComboPooledDataSource();
            QueryRunner queryRunner=new QueryRunner(dataSource);
            String sql="insert into user values(null,?,?,?)";
            int row = queryRunner.update(sql, user.getName(), user.getPassword(), user.getEmail());
            //行数大于零说明注册成功
            if (row>0) {
                return  true;
            }else {
                return  false;
            }
        } catch (SQLException e) {
            e.printStackTrace();
            return  false;
        }
    }
    /**
     * @method:login 查询数据库
     * @params:[name, password]
     * @return: void
     */
    public User login(String name, String password) throws SQLException {
       ComboPooledDataSource dataSource=new ComboPooledDataSource();
       QueryRunner queryRunner=new QueryRunner(dataSource);
       String sql="select * from user where name=? and password=?";
        User user = queryRunner.query(sql, new BeanHandler<User>(User.class),name,password);
        return  user;
    }
}

  （4）创建User实体类

package com.zzs.szsd.bean;

public class User {
    private int id;
    private String name;
    private String password;
    private String email;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
}

  （5）修改c3p0-config.xml
在这里插入图片描述

<?xml version="1.0" encoding="utf-8" ?>
<c3p0-config>
    <!-- 默认配置，如果没有指定则使用这个配置 -->
    <default-config>
        <property name="driverClass">com.mysql.jdbc.Driver</property>
        <property name="jdbcUrl">jdbc:mysql://localhost:3306/fresh?useSSL=false</property>
        <property name="user">root</property>
        <property name="password">admin123</property>
        <!-- 初始化池大小 -->
        <property name="initialPoolSize">10</property>
        <!-- 最大空闲时间 -->
        <property name="maxIdleTime">30</property>
        <!-- 最多有多少个连接 -->
        <property name="maxPoolSize">15</property>
        <!-- 最少几个连接 -->
        <property name="minPoolSize">5</property>
        <!-- 每次最多可以执行多少个批处理语句 -->
        <property name="maxStatements">50</property>
    </default-config>
    <!-- 命名的配置 -->
    <named-config name="51zixue"><!--这里是设置配置文件的名字-->
        <property name="driverClass">com.mysql.jdbc.Driver</property>
        <property name="jdbcUrl">jdbc:mysql://localhost:3306/fresh?useSSL=false</property>
        <property name="user">root</property><!--mysql的登陆名-->
        <property name="password">admin123</property><!--如果没密码就可以设置成<property name="password"></property>-->
        <property name="acquireIncrement">5</property><!-- 如果池中数据连接不够时一次增长多少个 -->
        <property name="initialPoolSize">10</property>
        <property name="minPoolSize">5</property>
        <property name="maxPoolSize">15</property>
        <property name="maxStatements">0</property>
        <property name="maxStatementsPerConnection">5</property> <!-- he's important, but there's only one of him -->
    </named-config>
</c3p0-config>

2. 生鲜后台管理系统-登录功能

2.1. 登录功能

  （1）创建注册LoginServlet，接收form表单中的参数。
  （2）LoginServlet将参数传递给servie层。
  （3）userService调用dao层，userDao将用户注册信息加入到数据库中。
  （4）登录成功后跳转到分类界面。

2.2. 步骤

  （1）新建LoginServlet

package com.zzs.szsd.web;
import com.zzs.szsd.bean.User;
import com.zzs.szsd.service.UserService;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.sql.SQLException;
@WebServlet(name = "LoginServlet",urlPatterns = "/login")
public class LoginServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String name = request.getParameter("name");
        String password = request.getParameter("password");
        UserService userService=new UserService();
        User user=null;
        try {
            //调用service中登录方法
            user = userService.login(name, password);
        } catch (SQLException e) {
            e.printStackTrace();
        }
        System.out.println("wed=w="+user);
        if (user!=null){
            //登录成功跳转生鲜种类列表界面
            response.sendRedirect(request.getContextPath()+"/category-list.jsp");
        }else {
            //登录失败提示
            response.setContentType("text/html;charset=utf-8");
            response.getWriter().write("用户登录失败");
        }

    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    }
}

  （2）新建login.jsp

3. 生鲜后台管理系统-记住密码功能

3.1. 记住密码

  （1）界面中添加checkbox控件。
  （2）如果用户登录成功，这时候就去获取控件是否被选中。
  （3）如果选中 那么我们需要将用户名和密码。
  （4）保存在cookie中保存到cookie中 同时需要对cookie做持久化，防止浏览器关闭的时候cookie被销毁
  （5）登录界面的jsp中 需要获取cookie中保存的信息，并将获取到的信息填入到form表单中。
  （6）这样就完成了记住密码的功能。

3.2. 步骤

  （1）新建LoginServlet

package com.zzs.szsd.web;
import com.zzs.szsd.bean.User;
import com.zzs.szsd.service.UserService;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.sql.SQLException;
@WebServlet(name = "LoginServlet",urlPatterns = "/login")
public class LoginServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request,
                          HttpServletResponse response)
            throws ServletException, IOException {
        String name = request.getParameter("name");
        String password = request.getParameter("password");

        UserService userService=new UserService();
        User user=null;
        try {
            //调用service中登录方法
            user = userService.login(name, password);
        } catch (SQLException e) {
            e.printStackTrace();
        }
        if (user!=null){
            //登录成功后我们再获取是否保存密码的信息，如果失败了保存密码就没有意义了
            String remember = request.getParameter("remember");
            if (remember.equals("yes")){
                // 将用户名和密码加入到cookie中
                Cookie nameCookie = new Cookie("name", name);
                Cookie passwordCookie = new Cookie("password", password);
                //设置cookie的有效期 防止销毁
                nameCookie.setMaxAge(60*10);
                passwordCookie.setMaxAge(60*10);
                //将cookie发送给客户端保存
                response.addCookie(nameCookie);
                response.addCookie(passwordCookie);
            }
            //登录成功跳转生鲜种类列表界面
            response.sendRedirect(request.getContextPath()+"/category-list.jsp");
        }else {
            //登录失败提示
            response.setContentType("text/html;charset=utf-8");
            response.getWriter().write("用户登录失败");

        }

    }
    protected void doGet(HttpServletRequest request,
                         HttpServletResponse response)
            throws ServletException, IOException {

    }
}

  （2）新建login.jsp
