JavaWeb用户信息管理系统-添加用户的实现

1 添加用户持久层

1.1 创建添加用户的持久层接口

public interface UserManagerDao {
    void insertUser(Users users);
}

1.2 持久层用户添加的接口实现类

/**
 * 用户管理持久层
 */
public class UserManagerDaoImpl implements UserManagerDao {

    @Override
    public void insertUser(Users users) {
        Connection conn = null;
        try{
            conn = JdbcUtils.getConnection();
            conn.setAutoCommit(false);
            PreparedStatement ps = conn.prepareStatement("insert into users values(default,?,?,?,?,?)");
            ps.setString(1,users.getUsername());
            ps.setString(2,users.getUserpwd());
            ps.setString(3,users.getUsersex());
            ps.setString(4,users.getPhonenumber());
            ps.setString(5,users.getQqnumber());
            ps.execute();
            conn.commit();
        }catch(Exception e){
            e.printStackTrace();
            JdbcUtils.rollbackConnection(conn);
        }finally{
            JdbcUtils.closeConnection(conn);
        }
    }

2 添加用户业务层

2.1 创建添加用户的业务层接口

public interface UserManagerService {
    void addUser(Users users);
}

2.2 创建添加用户的业务层实现类

/**
 * 用户管理业务层
 */
public class UserManagerServiceImpl implements UserManagerService {
    /**
     * 添加用户
     * @param users
     */
    @Override
    public void addUser(Users users) {
        UserManagerDao userManagerDao = new UserManagerDaoImpl();
        userManagerDao.insertUser(users);
    }
}

3 添加用户的 Servlet

/**
 * 处理用管理请求
 */
@WebServlet("/userManager.do")
public class UserManagerServlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        this.doPost(req, resp);
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        String flag = req.getParameter("flag");
        if("addUser".equals(flag)){
            this.addUser(req,resp);
        }
    }
    //处理添加用户请求
    private void addUser(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        Users users = this.createUsers(req);
        try{
            UserManagerService userManagerService = new UserManagerServiceImpl();
            userManagerService.addUser(users);
            resp.sendRedirect("ok.jsp");
        }catch(Exception e){
            e.printStackTrace();
            resp.sendRedirect("error.jsp");
        }
    }
    //获取用户提交数据
    private Users createUsers(HttpServletRequest req){
        String username = req.getParameter("username");
        String userpwd = req.getParameter("userpwd");
        String usersex = req.getParameter("usersex");
        String phonenumber = req.getParameter("phonenumber");
        String qqnumber = req.getParameter("qqnumber");
        Users users = new Users();
        users.setQqnumber(qqnumber);
        users.setPhonenumber(phonenumber);
        users.setUsername(username);
        users.setUserpwd(userpwd);
        users.setUsersex(usersex);
        return users;
    }
}

4 前台添加页面

将一个模块放入独立的文件，要不全是jsp文件过于臃肿。

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>

<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>无标题文档</title>
    <link href="../css/style.css" rel="stylesheet" type="text/css" />
    <link href="../css/style.css" rel="stylesheet" type="text/css" />
    <link href="../css/select.css" rel="stylesheet" type="text/css" />
</head>

<body>

<div class="place">
    <span>位置：</span>
    <ul class="placeul">
        <li><a href="#">用户管理</a></li>
        <li><a href="#">添加用户</a></li>
    </ul>
</div>

<div class="formbody">

    <div class="formtitle"><span>基本信息</span></div>
    <form action="../userManager.do" method="post">
        <input type="hidden"  name="flag" value="addUser"/>
    <ul class="forminfo">
        <li>
            <label>用户名</label>
            <input name="username" type="text" class="dfinput" /></li>
        <li>
        <li>
            <label>用户密码</label>
            <input name="userpwd" type="text" class="dfinput" /><i></i></li>
        <li>
            <label>性别</label><cite>
            <input name="usersex" type="radio" value="1" checked="checked" />男&nbsp;&nbsp;&nbsp;&nbsp;
            <input name="usersex" type="radio" value="0" />女

        </li>
        <li>
            <label>联系方式</label>
            <input name="phonenumber" type="text" class="dfinput" />
        </li>
        <li>
            <label>QQ号</label>
            <input name="qqnumber" type="text" class="dfinput" />
        </li>
        <li>
            <label>&nbsp;</label>
            <input  type="submit"  class="btn" value="确认保存" />
        </li>
    </ul>
    </form>
</div>

</body>

</html>

4.1 反馈成功的jsp页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title></title>
    <link href="css/style.css" rel="stylesheet" type="text/css" />
    <script type="text/javascript">
        function submitForm(){
            window.close();

        }

    </script>
</head>

<body>
<div class="place">
    <span>位置：</span>
    <ul class="placeul">
        <li><a href="#">操作提示</a></li>
    </ul>
</div>

操作成功!

</body>
</html>
