1.thymeleaf模板引擎自定义属性 th:attr="属性名=属性值"
<button th:attr="del_uri=@{/emp/}+${emp.id}" class="btn btn-sm btn-danger deleteBtn">删除</button>
2.使用delete删除请求
.....
<main role="main" class="col-md-9 ml-sm-auto col-lg-10 pt-3 px-4">
<h2><a class="btn btn-sm btn-success" href="emp" th:href="@{/emp}">员工添加</a></h2>
<div class="table-responsive">
<table class="table table-striped table-sm">
<thead>
<tr>
<th>#</th>
<th>lastName</th>
<th>email</th>
<th>gender</th>
<th>department</th>
<th>birth</th>
<th>操作</th>
</tr>
</thead>
<tbody>
<tr th:each="emp:${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>
</div>
</main>
<!--将form表单写在外面,所有的删除操作共用一个表单-->
<form id="deleteEmpForm" method="post">
<input type="hidden" name="_method" value="delete"/>
</form>
.....
<script>
$(".deleteBtn").click(function(){
//根据点击事件获取到的请求删除当前id
$("#deleteEmpForm").attr("action",$(this).attr("del_uri")).submit();
return false;
});
</script>
3.写一个删除功能的Controller,用@DeleteMapping("xxx")
//员工删除
@DeleteMapping("/emp/{id}")
public String deleteEmployee(@PathVariable("id") Integer id){
employeeDao.delete(id);
return "redirect:/emps";
}
