SpringBoot实现简单的CRUD

CRUD-员工列表

实验要求：

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

2）、实验的请求架构;

3）、员工列表：

thymeleaf公共页面元素抽取

1、抽取公共片段
<div th:fragment="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>

6）、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="[email protected]">
    </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}?${emp.lastName}">
    </div>
    <div class="form-group">
        <label>Email</label>
        <input name="email" type="email" class="form-control" placeholder="[email protected]" th:value="${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>

8）、CRUD-员工删除

            <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>
                <form id="deleteEmpForm"  method="post">
                    <input type="hidden" name="_method" value="delete"/>
                </form>
            </div>

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


EmployeeController：

package com.atguigu.springboot.controller;

import com.atguigu.springboot.dao.DepartmentDao;

@Controller
public class EmployeeController {
    @Autowired
    EmployeeDao employeeDao;

    @Autowired
    DepartmentDao departmentDao;

    //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";
    }

    //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";
    }

    //员工添加
    //SpringMVC自动将请求参数和入参对象的属性进行一一绑定；要求请求参数的名字和javaBean入参的对象里面的属性名是一样的
    @PostMapping("/emp")
    public String addEmp(Employee employee){
        //来到员工列表页面

        System.out.println("保存的员工信息："+employee);
        //保存员工
        employeeDao.save(employee);
        // redirect: 表示重定向到一个地址  /代表当前项目路径
        // forward: 表示转发到一个地址
        return "redirect:/emps";
    }

    //来到修改页面，查出当前员工，在页面回显
    @GetMapping("/emp/{id}")
    public String toEditPage(@PathVariable("id") Integer id,Model model){
        Employee employee = employeeDao.get(id);
        model.addAttribute("emp",employee);

        //页面要显示所有的部门列表
        Collection<Department> departments = departmentDao.getDepartments();
        model.addAttribute("depts",departments);
        //回到修改页面(add是一个修改添加二合一的页面);
        return "emp/add";
    }

    //员工修改；需要提交员工id；
    @PutMapping("/emp")
    public String updateEmployee(Employee employee){
        System.out.println("修改的员工数据："+employee);
        employeeDao.save(employee);
        return "redirect:/emps";

    //员工删除
    @DeleteMapping("/emp/{id}")
    public String deleteEmployee(@PathVariable("id") Integer id){
        employeeDao.delete(id);
