页面跳转

单击添加按钮，跳转到添加页面
可以选择员工的公寓，需要把公寓信息传递过去

添加按钮

<h2><a class="btn btn-sm btn-success" href="emp" th:href="@{/emp}">员工添加</a></h2>

Controller

//来到员工添加页面
@GetMapping("/emp")
public String toAddPage(Model model) {
    //来到添加页面,查出所有的部门，在页面显示
    Collection<Department> departments = departmentDao.getDepartments();
    model.addAttribute("depts", departments);
    return "emp/add";
}

添加页面

可以选择用户的公寓

<!--提交的是部门的id-->
<select class="form-control" name="department.id">
    <option th:selected="${emp!=null}?${dept.id == emp.department.id}" th:value="${dept.id}" th:each="dept:${depts}" th:text="${dept.departmentName}">1</option>
</select>

页面

<main role="main" class="col-md-9 ml-sm-auto col-lg-10 pt-3 px-4">
    <!--需要区分是员工修改还是添加；-->
    <form th:action="@{/emp}" method="post">
        <!--发送put请求修改员工数据-->
        <!--
        1、SpringMVC中配置HiddenHttpMethodFilter;（SpringBoot自动配置好的）
        2、页面创建一个post表单
        3、创建一个input项，name="_method";值就是我们指定的请求方式
        -->
        <input type="hidden" name="_method" value="put" th:if="${emp!=null}"/>
        <input type="hidden" name="id" th:if="${emp!=null}" th:value="${emp.id}">
