Springboot2.X 配置了 拦截器，会拦截所有资源
#properties 设置静态文件的解析路径，配置了登陆拦截器之后，便于放行
spring.mvc.static-path-pattern=/static/**

1）、RestfulCRUD：CRUD满足Rest风格；

URI： /资源名称/资源标识 HTTP请求方式区分对资源CRUD操作

 普通CRUD（uri来区分操作）RestfulCRUD
查询 getEmp emp---GET
添加 addEmp?xxx emp---POST
修改 updateEmp?id=xxx&xxx=xx emp/{id}---PUT
删除 deleteEmp?id=1 emp/{id}---DELETE

 

 

 

 

2）、实验的请求架构;

实验功能请求URI请求方式
查询所有员工 emps GET
查询某个员工(来到修改页面) emp/1 GET
来到添加页面 emp GET
添加员工 emp POST
来到修改页面（查出员工进行信息回显） emp/1 GET
修改员工 emp PUT
删除员工 emp/1 DELETE

 

 

 

 

 

 

 

thymeleaf公共页面元素抽取

1、抽取公共片段
<div th:fragment="copy">
&copy; 2011 The Good Thymes Virtual Grocery
</div>

2、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

3、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：[[~{}]];[(~{})]；

三种引入公共片段的th属性：

th:insert：将公共片段整个插入到声明引入的元素中

th:replace：将声明引入的元素替换为公共片段

th:include：将被引入的片段的内容包含进这个标签中

<footer th:fragment="copy">
&copy; 2011 The Good Thymes Virtual Grocery
</footer>

引入方式
<div th:insert="footer :: copy"></div>
<div th:replace="footer :: copy"></div>
<div th:include="footer :: copy"></div>

效果
<div>
    <footer>
    &copy; 2011 The Good Thymes Virtual Grocery
    </footer>
</div>

<footer>
&copy; 2011 The Good Thymes Virtual Grocery
</footer>

<div>
&copy; 2011 The Good Thymes Virtual Grocery
</div>

引入片段的时候传入参数：

<nav class="col-md-2 d-none d-md-block bg-light sidebar" id="sidebar">
    <div class="sidebar-sticky">
        <ul class="nav flex-column">
            <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>

<!--引入侧边栏;传入参数-->
<div th:replace="commons/bar::#sidebar(activeUri='emps')"></div>

 CRUD-员工添加

 添加页面

<form>
    <div class="form-group">
        <label>LastName</label>
        <input type="text" class="form-control" placeholder="zhangsan">
    </div>
    <div class="form-group">
        <label>Email</label>
        <input type="email" class="form-control" placeholder="zhangsan@atguigu.com">
    </div>
    <div class="form-group">
        <label>Gender</label><br/>
        <div class="form-check form-check-inline">
            <input class="form-check-input" type="radio" name="gender"  value="1">
            <label class="form-check-label">男</label>
        </div>
        <div class="form-check form-check-inline">
            <input class="form-check-input" type="radio" name="gender"  value="0">
            <label class="form-check-label">女</label>
        </div> 
    </div>
    <div class="form-group">
        <label>department</label>
        <select class="form-control">
            <option>1</option>
            <option>2</option>
            <option>3</option>
            <option>4</option>
            <option>5</option>
        </select>
    </div>
    <div class="form-group">
        <label>Birth</label>
        <input type="text" class="form-control" placeholder="zhangsan">
    </div>
    <button type="submit" class="btn btn-primary">添加</button>
</form>

提交的数据格式不对：生日：日期；

2017-12-12；2017/12/12；2017.12.12；

日期的格式化；SpringMVC将页面提交的值需要转换为指定的类型;

2017-12-12---Date； 类型转换，格式化;

默认日期是按照/的方式；

7）、CRUD-员工修改

修改添加二合一表单

<!--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="${emp.id}">
    <div class="form-group">
        <label>LastName</label>
        <input name="lastName" type="text" class="form-control" placeholder="zhangsan" th:value="${emp!=null}?${emp.lastName}">
    </div>
    <div class="form-group">
        <label>Email</label>
        <input name="email" type="email" class="form-control" placeholder="zhangsan@atguigu.com" th:value="${emp!=null}?${emp.email}">
    </div>
    <div class="form-group">
        <label>Gender</label><br/>
        <div class="form-check form-check-inline">
            <input class="form-check-input" type="radio" name="gender" value="1" th:checked="${emp!=null}?${emp.gender==1}">
            <label class="form-check-label">男</label>
        </div>
        <div class="form-check form-check-inline">
            <input class="form-check-input" type="radio" name="gender" value="0" th:checked="${emp!=null}?${emp.gender==0}">
            <label class="form-check-label">女</label>
        </div>
    </div>
    <div class="form-group">
        <label>department</label>
        <!--提交的是部门的id-->
        <select class="form-control" name="department.id">
            <option th:selected="${emp!=null}?${dept.id == emp.department.id}" th:value="${dept.id}" th:each="dept:${depts}" th:text="${dept.departmentName}">1</option>
        </select>
    </div>
    <div class="form-group">
        <label>Birth</label>
        <input name="birth" type="text" class="form-control" placeholder="zhangsan" th:value="${emp!=null}?${#dates.format(emp.birth, 'yyyy-MM-dd HH:mm')}">
    </div>
    <button type="submit" class="btn btn-primary" th:text="${emp!=null}?'修改':'添加'">添加</button>
</form>

CRUD-员工删除

<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>

<script>
    $(".deleteBtn").click(function(){
        //删除当前员工的
        $("#deleteEmpForm").attr("action",$(this).attr("del_uri")).submit();
        return false;
    });
</script>
