SSM小项目（会议管理系统）七注册审批和部门管理（图解超详细）

上一篇博客的地址：https://blog.csdn.net/qq_41115379/article/details/114336585
开始注册审批
在controller这边创建 approveaccountController

package org.javaboy.meeting.controller;

import org.javaboy.meeting.model.Employee;
import org.javaboy.meeting.service.EmployeeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/admin")
public class approveaccountController {
    
    
    //按照规范设置一个常数
    public static final Integer STATUS=0;
    @Autowired
    EmployeeService employeeService;
    @RequestMapping("/approveaccount")
    public String approveaccount(Model model){
    
    
        //通过mapping映射到对应的.ftl文件
        //因为需要上传用户未审批的信息 所以要传到前端对应的数据
        model.addAttribute("emps",employeeService.getAllEmp(STATUS));
        return "approveaccount";
    }
}

然后开始套娃
EmployeeService

public List<Employee> getAllEmp(Integer status) {
    
    
    return employeeMapper.getAllEmp(status);
}

EmployeeMapper

List<Employee> getAllEmp(Integer status);

EmployeeMapper.xml

<select id="getAllEmp" parameterType="org.javaboy.meeting.model.Employee">
    select * from employee where status=#{
    
    status};
</select>

再修改approveaccount.ftl

<!DOCTYPE html>
<html>
    <head>
        <title>CoolMeeting会议管理系统</title>
        <link rel="stylesheet" href="/styles/common.css"/>
        <style type="text/css">

    </head>
    <body>
    <#include 'top.ftl'>
        <div class="page-body">
            <#include 'leftMenu.ftl'>
            <div class="page-content">
                <div class="content-nav">
                    人员管理 > 注册审批
                </div>
                <table class="listtable">
                    <caption>所有待审批注册信息：</caption>
                    <tr class="listheader">
                        <th>姓名</th>
                        <th>账号名</th>
                        <th>联系电话</th>
                        <th>电子邮件</th>
                        <th>操作</th>
                    </tr>
                    <#if emps ??>
                        <#list emps as emp>
                            <tr>
                                <td>${emp.employeename}</td>
                                <td>${emp.username}</td>
                                <td>${emp.phone}</td>
                                <td>${emp.email}</td>
                                <td>
                                    <input type="button" class="clickbutton" value="通过"/>
                                    <input type="button" class="clickbutton" value="删除"/>
                                </td>
                            </tr>
                        </#list>
                    </#if>
                </table>
            </div>
        </div>
        <div class="page-footer">
            <hr/>
            更多问题，欢迎联系<a href="mailto:[email protected]">管理员</a>
            <img src="/images/footer.png" alt="CoolMeeting"/>
        </div>
    </body>
</html>

运行以 linyk登录（删除多余的linyk）点击注册审批就行了
在这里插入图片描述
优化通过和删除两个按钮
首先修改approveaccount.ftl

<a type="button" class="clickbutton" href="/admin/updatestatus?employeeid=${emp.employeeid}&status=1"/>通过</a>
<a type="button" class="clickbutton" href="/admin/updatestatus?employeeid=${emp.employeeid}&status=2"/>不通过</a>

这里提到了@param注解：@Param这个注解是用来解决接口方法有多个参数时、xxMapper.xml文件绑定参数混淆问题。
approveaccountController

@RequestMapping("/updatestatus")
public String updatestatus(Integer employeeid,Integer status){
    
    
   Integer result=employeeService.updatestatus(employeeid,status);
   //并且操作完成之后，就会返回到当前的页面
   return "redirect:/admin/approveaccount";
}

employeeService

public Integer updatestatus(Integer employeeid, Integer status) {
    
    
    return employeeMapper.updatestatus(employeeid,status);
}

employeeMapper

Integer updatestatus(@Param("employeeid") Integer employeeid,@Param("status") Integer status);

employeeMapper.xml

<update id="updatestatus">
    update employee set status =#{status} where employeeid=#{employeeid};
</update>

再运行一下，以 linyk登录（删除多余的linyk）点击注册审批
在这里插入图片描述
通过的会在数据库中显示出来

部门管理
修改DepartmentController

@Autowired
DepartmentService departmentService;
@GetMapping("/departments")
public  String departments(Model model){
    
    

    model.addAttribute("department",departmentService.getAllDeps());
    return "departments";
}

再对department.ftl进行简单修改

<!DOCTYPE html>
<html>
    <head>
        <title>CoolMeeting会议管理系统</title>
        <link rel="stylesheet" href="/styles/common.css"/>
    </head>
    <body>
    <#include 'top.ftl'>
        <div class="page-body">
            <#include 'leftMenu.ftl'>
            <div class="page-content">
                <div class="content-nav">
                    人员管理 > 部门管理
                </div>
                <form>
                    <fieldset>
                        <legend>添加部门</legend>
                        部门名称:
                        <input type="text" id="departmentname" maxlength="20"/>
                        <input type="submit" class="clickbutton" value="添加"/>
                    </fieldset>
                </form>
                <table class="listtable">
                    <caption>所有部门:</caption>
                    <tr class="listheader">
                        <th>部门编号</th>
                        <th>部门名称</th>
                        <th>操作</th>
                    </tr>
                    <#if deps??>
                            <#list deps as dep>
                          <tr>
                            <td>${dep.departmentid}</td>
                            <td>${dep.departmentname}</td>
                            <td>
                                <a class="clickbutton" href="#">编辑</a>
                                <a class="clickbutton" href="#">删除</a>
                            </td>
                        </tr>
                        </#list>
                    </#if>

                </table>
            </div>
        </div>
        <div class="page-footer">
            <hr/>
            更多问题，欢迎联系<a href="mailto:[email protected]">管理员</a>
            <img src="/images/footer.png" alt="CoolMeeting"/>
        </div>
    </body>
</html>

运行一下
在这里插入图片描述
再做一下添加的功能

<form action="/admin/adddepartment">
    <fieldset>
        <legend>添加部门</legend>
        部门名称:
        <input type="text" name="departmentname" id="departmentname" maxlength="20"/>
        <input type="submit" class="clickbutton" value="添加"/>
    </fieldset>
</form>

修改DepartmentController

@GetMapping("/adddepartment")
//通过departmentname来添加的
public String adddepartment(String departmentname){
    
    
    //感觉是需要刷新吧 但我这里还没用Integer 不行，不然不能返回
   departmentService.adddepartment(departmentname);
    return "redirect:/admin/departments";
}

departmentService

public  Integer adddepartment(String departmentname) {
    
    
    return departmentMapper.adddepartment(departmentname);
}

departmentMapper

Integer adddepartment(String departmentname);

departmentMapper.xml

<insert id="adddepartment" parameterType="java.lang.String">
    insert into department (departmentname) value (#{
    
    departmentname});
</insert>

运行一下
添加成功
在这里插入图片描述
数据库里也存在

再开始修改编辑

<a class="clickbutton" href="/admin/deletedep?departmentid=${dep.departmentid}">删除</a>

DepartmentController

@GetMapping("/deletedep")
public String deletedep(Integer departmentid){
    
    
    //是通过id来删除的
    departmentService.deletedep(departmentid);
    //并且无论成功或失败都回到当前页面
    return "redirect:/admin/departments";

}

DepartmentService

public Integer deletedep(Integer departmentid) {
    
    
    return departmentMapper.deletedep(departmentid);
}

departmentMapper

Integer deletedep(Integer departmentid);

departmentMapper.xml

<delete id="deletedep">
    delete from department where departmentid=#{
    
    departmentid};
</delete>

运行之后就可以进行删除了，数据库里也不存在对应数据
