     private UserDao userDao;
     public UserServiceImpl(){
         userDao = new UserDaoImpl();
     }
     @Override
     public User login(String userCode, String userPassword) {

         User user = null;
         try {
             connection = BaseDao.getConnection();
             user = userDao.getLoginUser(connection, userCode);
         } catch (Exception e) {

编写Servlet (servlet/user/LoginServlet) - (注意需定义常量导入 util/Constants)

 public class LoginServlet extends HttpServlet {
     @Override
     public void doGet(HttpServletRequest request, HttpServletResponse response)
             throws ServletException, IOException {
     }
     @Override
     public void doPost(HttpServletRequest request, HttpServletResponse response)
             throws ServletException, IOException {
 
         System.out.println("login ============ " );
         //获取用户名和密码
         String userCode = request.getParameter("userCode");
         String userPassword = request.getParameter("userPassword");
         //调用service方法，进行用户匹配
         UserService userService = new UserServiceImpl();
         User user = userService.login(userCode,userPassword);
         //登录成功
         if(null != user){
             //放入session
             request.getSession().setAttribute(Constants.USER_SESSION, user);
             //页面跳转（frame.jsp）
             response.sendRedirect("jsp/frame.jsp");
         }else{
             //页面跳转（login.jsp）带出提示信息--转发
             request.setAttribute("error", "用户名或密码不正确");
             request.getRequestDispatcher("login.jsp").forward(request, response);
         }
     }
 }

注册Servlet

 <servlet>
     <servlet-name>LoginServlet</servlet-name>
     <servlet-class>com.study.servlet.user.LoginServlet</servlet-class>
   </servlet>
 <servlet-mapping>
     <servlet-name>LoginServlet</servlet-name>
     <url-pattern>/login.do</url-pattern>
   </servlet-mapping>

测试访问!

使用到的页面:login.jsp(登录),jsp/frame.jsp(首页)

(3)注销及权限过滤 P32

登录功能优化 - 注销用户|注册 (servlet/user/LogoutServlet)

 /**
  * 退出登录，移除session中的用户对象Constants.USER_SESSION
  * */
 public class LogoutServlet extends HttpServlet {
 
     public LogoutServlet() {
         super();
     }
 
     @Override
     public void destroy() {
         super.destroy();
     }
 
     @Override
     public void doGet(HttpServletRequest request, HttpServletResponse response)
             throws ServletException, IOException {
         doPost(request, response);
     }
 
     @Override
     public void doPost(HttpServletRequest request, HttpServletResponse response)
             throws ServletException, IOException {
         //清除session
         request.getSession().removeAttribute(Constants.USER_SESSION);
         response.sendRedirect(request.getContextPath()+"/login.jsp");
     }
 
     @Override
     public void init() throws ServletException {
 
     }
 
 }

登录拦截优化 - 用户登录过滤器|注册 (filter/SysFilter)

 /**
  * 判断是否退出登录
  * */
 public class SysFilter implements Filter {
 
     @Override
     public void init(FilterConfig filterConfig) throws ServletException {
 
     }
 
     @Override
     public void doFilter(ServletRequest request, ServletResponse response,FilterChain chain) throws IOException, ServletException {
         //判断用户是否退出登录 - 当退出后禁止进入主页
         System.out.println("-- SysFilter doFilter()");
         HttpServletRequest rq = (HttpServletRequest)request;
         HttpServletResponse rp = (HttpServletResponse)response;
         //过滤器,从session中获取用户
         User userSession = (User)rq.getSession().getAttribute("userSession");
         if(null == userSession){ //用户以移除或注销或未登录
             rp.sendRedirect(rq.getContextPath()+"/error.jsp");
         }else{
             chain.doFilter(request, response);
         }
     }
 
     @Override
     public void destroy() {
 
     }
 
 }

 <servlet>
   <servlet-name>LoginServlet</servlet-name>
   <servlet-class>com.study.servlet.user.LoginServlet</servlet-class>
 </servlet>
 <servlet-mapping>
   <servlet-name>LogoutServlet</servlet-name>
   <url-pattern>/jsp/logout.do</url-pattern>
 </servlet-mapping>
 <filter>
   <filter-name>SysFilter</filter-name>
   <filter-class>com.study.filter.SysFilter</filter-class>
 </filter>
 <filter-mapping>
   <filter-name>SysFilter</filter-name>
   <url-pattern>/jsp/*</url-pattern>
 </filter-mapping>

使用到的页面:error.jsp(错误)

(4)密码修改 P33

UserDao接口 (dao/user/UserDao)

 //dao/user/UserDao添加接口
 //修改密码
 public int updatePwd(Connection connection, int id, String pwd)throws Exception;

UserDao接口实现类 (dao/user/UserDaoImpl)

 //dao/user/UserDaoImpl添加实现方法
 //修改密码
     @Override
     public int updatePwd(Connection connection, int id, String pwd) throws Exception {
         int flag = 0;
         PreparedStatement pstm = null;
         if(connection != null){
             String sql = "update smbms_user set userPassword= ? where id = ?";
             Object[] params = {pwd,id};
             flag = BaseDao.execute(connection, pstm, sql, params);
             BaseDao.closeResource(null, pstm, null);
         }
         return flag;
     }

实现类

UserService接口 (service/user/UserService)

 //根据userId修改密码
     public boolean updatePwd(int id, String pwd);

UserService接口实现类 (service/user/UserServiceImpl)

 @Override
     public boolean updatePwd(int id, String pwd) {
         boolean flag = false;
         Connection connection = null;
         try{
             connection = BaseDao.getConnection();
             if(userDao.updatePwd(connection,id,pwd) > 0)
                 flag = true;
         }catch (Exception e) {
             e.printStackTrace();
         }finally{
             BaseDao.closeResource(connection, null, null);
         }
         return flag;
     }

实现类

编写Servlet (servlet/user/UserServlet)

 public class UserServlet extends HttpServlet {
     public UserServlet() {
         super();
     }
     @Override
     public void destroy() {
         super.destroy();
     }
     @Override
     public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
         doPost(request, response);
     }
 
     @Override
     public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
         String method = request.getParameter("method");
         System.out.println("* method --> " + method);
         /*实现Servlet复用 - 新增的操作都可以在此处调用 - 通过前端获取表单的method值*/
         if(method != null && method.equals("pwdmodify")){
             this.getPwdByUserId(request, response);
         }else if(method != null && method.equals("savepwd")){
             this.updatePwd(request, response);
         }
     }
     //更新密码
     private void updatePwd(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
         Object o = request.getSession().getAttribute(Constants.USER_SESSION);
         String newpassword = request.getParameter("newpassword");
         boolean flag = false;
         if(o != null && !StringUtils.isNullOrEmpty(newpassword)){
             UserService userService = new UserServiceImpl();
             flag = userService.updatePwd(((User)o).getId(),newpassword);
             if(flag){
                 request.setAttribute(Constants.SYS_MESSAGE, "修改密码成功,请退出并使用新密码重新登录！");
                 request.getSession().removeAttribute(Constants.USER_SESSION);//session注销
             }else{
                 request.setAttribute(Constants.SYS_MESSAGE, "修改密码失败！");
             }
         }else{
             request.setAttribute(Constants.SYS_MESSAGE, "修改密码失败！");
         }
         request.getRequestDispatcher("pwdmodify.jsp").forward(request, response);
     }
     //获取旧密码
     //.....代码在下方
     public void init() throws ServletException { }
 }

 <servlet>
     <servlet-name>UserServlet</servlet-name>
     <servlet-class>com.study.servlet.user.UserServlet</servlet-class>

#旧密码验证 P34

优化密码修改使用 Ajax

 <!--fastjson依赖-处理json字符串-->
     <dependency>
       <groupId>com.alibaba</groupId>
       <artifactId>fastjson</artifactId>
       <version>1.2.62</version>
     </dependency>

//获取旧密码 - 配合pwdmodify.js
 private void getPwdByUserId(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
     Object o = request.getSession().getAttribute(Constants.USER_SESSION);
     String oldpassword = request.getParameter("oldpassword");
     Map<String, String> resultMap = new HashMap<String, String>();
     if(null == o ){//session过期
         resultMap.put("result", "sessionerror");
     }else if(StringUtils.isNullOrEmpty(oldpassword)){//旧密码输入为空
         resultMap.put("result", "error");
     }else{
         String sessionPwd = ((User)o).getUserPassword();
         if(oldpassword.equals(sessionPwd)){
             resultMap.put("result", "true");
         }else{//旧密码输入不正确
             resultMap.put("result", "false");
         }
     }
     response.setContentType("application/json");
     PrintWriter outPrintWriter = response.getWriter();
     outPrintWriter.write(JSONArray.toJSONString(resultMap));
     outPrintWriter.flush();
     outPrintWriter.close();
 }
