{ display: false, } } }); </script> </body> </html>
(3)把员工管理处的<li>标签修改成如下,超链接处修改成 th:href="@{/emps}"
<li class="nav-item"> <a class="nav-link" th:href="@{/emps}"> <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="feather feather-users"> <path d="M17 21v-2a4 4 0 0 0-4-4H5a4 4 0 0 0-4 4v2"></path> <circle cx="9" cy="7" r="4"></circle> <path d="M23 21v-2a4 4 0 0 0-3-3.87"></path> <path d="M16 3.13a4 4 0 0 1 0 7.75"></path> </svg> 员工管理 </a> </li>
(4)在controller层中添加一个EmployeeController.java,用来处理与员工相关的请求(src/main/java/com/azuma/springboot/controller/EmployeeController.java)
@Controller public class EmployeeController { @Autowired EmployeeDao employeeDao; //查询所有员工返回列表页面 @GetMapping("/emps") public String list(Model model){ Collection<Employee> employees = employeeDao.getAll(); //放在请求域中 model.addAttribute("emps",employees); // thymeleaf默认就会拼串 // classpath:/templates/xxxx.html return "emp/list"; } }
4.主页面中公共页面的抽取
抽取公共片段 <div th:fragment="copy"> © 2011 The Good Thymes Virtual Grocery </div> 引入公共片段 <div th:insert="~{footer :: copy}"></div> ~{templatename::selector}:模板名::选择器 ~{templatename::fragmentname}:模板名::片段名 默认效果: insert的公共片段在div标签中 如果使用th:insert等属性进行引入,可以不用写~{}: 行内写法可以加上:[[~{}]];[(~{})];
(1)首先完成src/main/resources/templates/dashboard.html中头部的抽取,div中添加 th:fragment="copy"
<nav class="navbar navbar-dark sticky-top bg-dark flex-md-nowrap p-0" th:fragment="topbar"> <!--th:fragment="topbar"中的名字任意起--> <a class="navbar-brand col-sm-3 col-md-2 mr-0" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">Company name</a> <input class="form-control form-control-dark w-100" type="text" placeholder="Search" aria-label="Search"> <ul class="navbar-nav px-3"> <li class="nav-item text-nowrap"> <a class="nav-link" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">Sign out</a> </li> </ul> </nav>
(2)删除list.html中重复的与上面(1)中重复的头部代码,并引入公共topbar
<!--引入抽取的topbar--> <!--模板名:会使用thymeleaf的前后缀配置规则进行解析--> <div th:replace="dashboard::topbar"></div>
(3)ps1.注意,list.html中的员工列表英文同样改成中文,要不然进入list.html中员工列表标题还是会显示英文
ps2.要想左上角的Company name显示用户的登录名称,需要在共同头部中把
<a class="navbar-brand col-sm-3 col-md-2 mr-0" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">Company name</a>
修改成:
<a class="navbar-brand col-sm-3 col-md-2 mr-0" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">[[${session.loginUser}]]</a>
5.主界面的侧边栏公共页面提取(使用~{templatename::selector}:模板名::选择器 的方法)
(1)src/main/resources/templates/dashboard.html中侧边栏的div中,添加id选择器
<div class="container-fluid"> <div class="row"> <nav class="col-md-2 d-none d-md-block bg-light sidebar" id="sidebar"> <!--添加 id="sidebar",这个就是templatename::selector中的id--> <div class="sidebar-sticky"> <ul class="nav flex-column"> <li class="nav-item"> <a class="nav-link active" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#"> <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="feather feather-home"> <path d="M3 9l9-7 9 7v11a2 2 0 0 1-2 2H5a2 2 0 0 1-2-2z"></path> <polyline points="9 22 9 12 15 12 15 22"></polyline> </svg> Dashboard <span class="sr-only">(current)</span> </a>
(2)删除list.html中与(1)重复的代码,并引入sidebar
<div th:replace="dashboard::topbar"></div> <div class="container-fluid"> <div class="row"> <!--引入侧边栏--> <div th:replace="dashboard::#sidebar"></div> <main role="main" class="col-md-9 ml-sm-auto col-lg-10 pt-3 px-4">
(3)启动服务器进行测试,可以看到侧边栏正常显示
6.点击左侧员工列表的标题高亮显示功能的实现
(1)新建一个文件夹,并创建一个公共bar的HTML(src/main/resources/templates/commons/bar.html)不要忘记引入xmlns:th="http://www.thymeleaf.org" 了
公共头部 topbar
<!--topbar--> <nav class="navbar navbar-dark sticky-top bg-dark flex-md-nowrap p-0" th:fragment="topbar"> <a class="navbar-brand col-sm-3 col-md-2 mr-0" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">[[${session.loginUser}]]</a> <input class="form-control form-control-dark w-100" type="text" placeholder="Search" aria-label="Search"> <ul class="navbar-nav px-3"> <li class="nav-item text-nowrap"> <a class="nav-link" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">Sign out</a> </li> </ul> </nav>
侧边栏 sidebar

(2)在src/main/resources/templates/dashboard.html和src/main/resources/templates/emp/list.html都引入topbar和sidebar(两个页面引入的代码是一样的,故此处只写一个)
<!--引入抽取的topbar--> <!--模板名:会使用thymeleaf的前后缀配置规则进行解析--> <div th:replace="commons/bar::topbar"></div>
<div class="container-fluid"> <div class="row"> <!--引入侧边栏--> <div th:replace="commons/bar::#sidebar"></div> <main role="main" class="col-md-9 ml-sm-auto col-lg-10 pt-3 px-4">
(3)启动服务器进行测试,可以看到页面正常显示
(4)回到编译器,修改bar.html中的代码,添加相关判断(此时activeUri会报错,不用管)
员工管理处添加activeUri
<li class="nav-item"> <a class="nav-link active" href="#" th:href="@{/emps}" th:class="${activeUri=='emps'?'nav-link active':'nav-link'}"> <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="feather feather-users"> <path d="M17 21v-2a4 4 0 0 0-4-4H5a4 4 0 0 0-4 4v2"></path> <circle cx="9" cy="7" r="4"></circle> <path d="M23 21v-2a4 4 0 0 0-3-3.87"></path> <path d="M16 3.13a4 4 0 0 1 0 7.75"></path> </svg> 员工管理 </a> </li>
Dashboard处添加activeUri
<li class="nav-item"> <a class="nav-link active" th:class="${activeUri=='main.html'?'nav-link active':'nav-link'}" href="#" th:href="@{/main.html}"> <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="feather feather-home"> <path d="M3 9l9-7 9 7v11a2 2 0 0 1-2 2H5a2 2 0 0 1-2-2z"></path> <polyline points="9 22 9 12 15 12 15 22"></polyline> </svg> Dashboard <span class="sr-only">(current)</span> </a> </li>
(5)在在src/main/resources/templates/dashboard.html和src/main/resources/templates/emp/list.html引入sidebar的地方修改
dashboard
<!--引入sidebar--> <div th:replace="commons/bar::#sidebar(activeUri='main.html')"></div>
list
<!--引入侧边栏--> <div th:replace="commons/bar::#sidebar(activeUri='emps')"></div>
(6)启动服务器进行测试,可以看到点击员工列表有高亮显示了
7.在list.html中添加循环语句输出员工列表
(1)table中添加循环语句
<table class="table table-striped table-sm"> <thead> <tr> <th>#</th> <th>lastName</th> <th>email</th> <th>gender</th> <th>department</th> <th>birth</th> </tr> </thead> <tbody> <tr th:each="emp:${emps}"> <td th:text="${emp.id}"></td> <td>[[${emp.lastName}]]</td> <td th:text="${emp.email}"></td> <td th:text="${emp.gender}==0?'女':'男'"></td> <td th:text="${emp.department.departmentName}"></td> <td th:text="${emp.birth}"></td> </tr> </tbody> </table>
(2)启动服务器可以看到员工列表出的信息可以显示出来了,只是日期格式有问题,接下来修改日期格式(把原来的替换成下面这样子的格式)
<td th:text="${#dates.format(emp.birth, 'yyyy-MM-dd HH:mm')}"></td>
(3)添加操作按钮(如下的<th>操作</th>的编辑和删除按钮),最终变成以下的样子
<table class="table table-striped table-sm"> <thead> <tr> <th>#</th> <th>lastName</th> <th>email</th> <th>gender</th> <th>department</th> <th>birth</th> <th>操作</th> </tr> </thead> <tbody> <tr th:each="emp:${emps}"> <td th:text="${emp.id}"></td> <td>[[${emp.lastName}]]</td> <td th:text="${emp.email}"></td> <td th:text="${emp.gender}==0?'女':'男'"></td> <td th:text="${emp.department.departmentName}"></td> <td th:text="${#dates.format(emp.birth, 'yyyy-MM-dd HH:mm')}"></td> <td> <a class="btn btn-sm btn-primary" th:href="@{/emp/}+${emp.id}">编辑</a> <button th:attr="del_uri=@{/emp/}+${emp.id}" class="btn btn-sm btn-danger deleteBtn">删除</button> </td> </tr> </tbody> </table>
(4)员工列表查看功能已编辑完成,接下来是员工添加功能
