1、遍历

  1. <div class="panel-body">
  2.      <div class="adv-table">
  3.           <table class="display table table-bordered table-striped" id="dynamic-table">
  4.                  <thead>
  5.                         <tr>
  6.                             <th>#</th>
  7.                             <th>name</th>
  8.                             <th>age</th>
  9.                             <th>email</th>
  10.                             <th>操作</th>
  11.                          </tr>
  12.                   </thead>
  13.                   <tbody>
  14.                          <tr class="gradeX" th:each="user: ${users.records}">
  15.                              <td th:text="${user.id}"></td>
  16.                              <td>[[${user.name}]]</td>
  17.                              <td th:text="${user.age}">Win 95+</td>
  18.                              <td th:text="${user.email}">4</td>
  19.                              <td><a th:href="@{/user/delete/{id}(id=${user.id},pn=${users.current})}" class="btn btn-danger btn-sm" type="button">删除</a>
  20.                                         </td>
  21.                            </tr>
  22.                    </table>
  24. <div class="row-fluid">
  25.      <div class="span6">
  26.           <div class="dataTables_info" id="dynamic-table_info">
  27.                                             当前第[[${users.current}]]页  总计 [[${users.pages}]]页  共[[${users.total}]]条记录
  28.                                         </div>
  29.      </div>
  30.      <div class="span6">
  31.           <div class="dataTables_paginate paging_bootstrap pagination">
  32.                <ul>
  33.                  <li class="prev disabled">
  34.                      <a href="#">← 前一页</a>
  35.                  </li>
  36.                  <li th:class="${num == users.current?'active':''}" th:each="num:${#numbers.sequence(1,users.pages)}" >

  40.                </ul>
  41.            </div>
  42.       </div>
  43.   </div>
  44. </div>
  45. </div>

2、拦截器

2.1 自定义的拦截器

  1. /**
  2.  * 拦截器作用：登录检查
  3.  * @author dongxinxin
  4.  * @create 2022-01-27 10:47
  5.  */
  6. public class LoginInterceptor implements HandlerInterceptor{
  8.     /**
  9.      * 登陆前的检查
  10.      * 1、配置好拦截器拦截那些请求
  11.      * 2、将这些配置放在容器当中
  12.      * @param request
  13.      * @param response
  14.      * @param handler
  15.      * @return
  16.      * @throws Exception
  17.      */
  18.     @Override
  19.     public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
  20.         //登录前检查的逻辑
  21.         HttpSession session = request.getSession();
  22.         Object loginUser = session.getAttribute("LoginUser");
  23.         if(loginUser != null){
  24.             //放行
  25.             return true;
  26.         }
  27.         //拦截，也就是未登录，直接跳转到登录页
  28.         //此时也可将错误信息放在session中
  29. //        response.sendRedirect("/");
  30.         request.setAttribute("msg","请重新登陆");
  31.         request.getRequestDispatcher("/").forward(request,response);
  32.         return false;
  33.     }
  35.     /**
  36.      * 目标方法执行后进行的拦截
  37.      * Controller方法处理完之后，DispatcherServlet进行视图的渲染之前，也就是说在这个方法中你可以对ModelAndView进行操作
  38.      * @param request
  39.      * @param response
  40.      * @param handler
  41.      * @param modelAndView
  42.      * @throws Exception
  43.      */
  44.     @Override
  45.     public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
  47.     }
  49.     /**
  50.      * DispatcherServlet进行视图的渲染之后
  51.      * @param request
  52.      * @param response
  53.      * @param handler
  54.      * @param ex
  55.      * @throws Exception
  56.      */
  57.     @Override
  58.     public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
  60.     }
  61. }

2.2 配置文件

  1. /**
  2.  * @author dongxinxin
  3.  * @create 2022-01-27 10:52
  4.  */
  5. @Configuration
  6. public class AdminConfig implements WebMvcConfigurer {
  8.     /**
  9.      * addInterceptor(new LoginInterceptor())
  10.      * 该方法是将我们自己的拦截器先添加到配置当中
  11.      * addPathPatterns("/**")
  12.      * 该方法是拦截所有请求
  13.      * excludePathPatterns("/","/login")
  14.      * 该方法是对那些请求进行放行
  15.      *
  16.      * "/css/**"
  17.      * 表示对css文件下的文件进行放行，以此类推
  18.      * @param registry
  19.      */
  20.     @Override
  21.     public void addInterceptors(InterceptorRegistry registry) {
  22.         registry.addInterceptor(new LoginInterceptor())
  23.                 .addPathPatterns("/**")//所有静态资源都会进行拦截
  24.                 .excludePathPatterns("/","/login","/css/**","/js/**");//只进行放行的资源
  25.     }
  26. }
