SpringBoot-06 员工管理系统

SpringBoot-06 员工管理系统

一、环境搭建

1.新建SpringBoot项目

具体步骤如图:

1 2 3

之后就是起好项目名,然后完成创建。

4

红框中的可以自行选择删除,不删除也没事情。

2.导入静态资源

静态资源文件:https://pan.baidu.com/s/1xjkUFp0ke73tUxM6SUJaSw

提取码:m2yf

或者大家自己自己下载一个静态资源文件:

BootStrap静态模板:https://getbootstrap.com/docs/4.0/examples/

5

  • html文件放入templates文件夹
  • asserts中的css、js、img文件夹放入static文件夹(或者public、resources,看心情)
6

3.模拟数据库

创建pojodaoController包,记得要在启动器同级目录下创建。

  • pojo实体类 作为 数据库表
  • dao实现类 作为 添加原始数据以及数据库操作。

3.1 pojo实体类

部门类,Department:

//部门表
public class Department {
   private Integer id;            //部门id
   private String departmentName; //部门名称
   // 有参/无参方法
   // Get/Set方法
   // toString()方法
}

员工类,Employee:

//员工表
public class Employee {
    private Integer id;      //员工id
    private String lastName; //员工姓名
    private String email;    //员工邮箱
    private Integer gender;  //员工性别  0 女  1 男
    private Department department; //员工部门
    private Date birth;            //员工生日
   // 有参/无参方法
   // Get/Set方法
   // toString()方法  
}

这里需要注意这个员工生日,你可以在实体类中让他自己创建:

// 参数中删除 Date date
public Employee(Integer id, String lastName, String email, Integer gender, Department department) {
    this.id = id;
    this.lastName = lastName;
    this.email = email;
    this.gender = gender;
    this.department = department;
    this.birth = new Date();    //默认创建日期
}

当然,你也可以在之后添加数据的时候,每次在date对应位置写 new Date();

3.2 dao实现类

部门dao类,DepartmentDao:

@Repository   //注册进Spring容器
public class DepartmentDao {
    //模拟数据库中数据
    private static Map<Integer, Department> departments = null;
    static {
        departments = new HashMap<>();  //创建部门表
        departments.put(101,new Department(101,"教学部"));
        departments.put(102,new Department(102,"市场部"));
        departments.put(103,new Department(103,"教研部"));
        departments.put(104,new Department(104,"运营部"));
        departments.put(105,new Department(105,"后勤部"));
    }
    //数据库操作
    //获取所有部门信息
    public Collection<Department> getDepartments(){
        return departments.values();
    }
    //通过id获得部门
    public Department getDepartment(Integer id){
        return departments.get(id);
    }
}

员工dao类,EmployeeDao:

@Repository
public class EmployeeDao {
    //模拟数据库
    private static Map<Integer, Employee> employees = null;
    @Autowired
    private DepartmentDao departmentDao;
    static {
        employees = new HashMap<Integer, Employee>();
        employees.put(1001,new Employee(1001,"AA","1@qq.com",1,new Department(101,"教学部")));
        employees.put(1002,new Employee(1002,"BB","2@qq.com",0,new Department(102,"市场部")));
        employees.put(1003,new Employee(1003,"CC","3@qq.com",1,new Department(103,"教研部")));
        employees.put(1004,new Employee(1004,"DD","4@qq.com",1,new Department(104,"运营部")));
        employees.put(1005,new Employee(1005,"EE","5@qq.com",0,new Department(105,"后勤部")));
    }
    //主键自增
    private static Integer id=1006;
    //数据操作
    //增加一个员工
    public  void save(Employee employee){
        if (employee.getId()==null){
            employee.setId(id++);
        }     employee.setDepartment(departmentDao.getDepartment(employee.getDepartment().getId()));
        employees.put(employee.getId(),employee);
    }
    //查询全部员工信息
    public Collection<Employee> getEmployees(){
        return employees.values();
    }
    //通过id查询员工
    public Employee getEmployee(Integer id){
        return employees.get(id);
    }
    //删除员工
    public void delEmployee(Integer id){
         employees.remove(id);
    }
}

以上,环境搭建完成。

二、首页以及前端路径改写

1.首先得先让http://localhost:8080/这个路径可以直接访问index.html

7

这时候可以看到,网页是正常访问的,但是静态资源都没有加载。

2.加载静态资源

<html lang="en" xmlns:th="http://www.thymeleaf.org">
  • 在html文件头部加入thymeleaf头文件

  • 将html页面静态资源的标签改为th:xxx

  • 加载路径规则:@{xxx}

<link th:href="@{/css/bootstrap.min.css}" rel="stylesheet">
<link th:href="@{/css/signin.css}" rel="stylesheet">
<img class="mb-4" th:src="@{/img/bootstrap-solid.svg}" alt="" width="72" height="72">

之后最后一步:关闭模板引擎缓存

spring.thymeleaf.cache=false
8

然后把全部的前端页面都改写就可以了。

三、页面国际化

首先,要确定你的项目是UTF-8:

9

3.1 实现跟随浏览器语言切换

1.在resources中创建一个i18n文件夹,中间创建login.properties(默认语言)login_zh_CN.properties(汉语)、**login_en_US.properties(英语) ** 【直接创建,会自动合并】

10

2.配置语言,你可以选择一个文件一个文件输入,也可以进行可视化输入

11
login.password=密码
login.tip=请登录
login.remember=记住我
login.btn=登录
login.username=用户名
login.password=password
login.tip=Please sign in
login.remember=Remember me
login.btn=Sign in
login.username=username

3.开启国际化 i18n下的login

spring.messages.basename=i18n.login

4.修改html文件,以index.html为例

对于国际化信息用 #{ xxxx }

<body class="text-center">
    <form class="form-signin" action="dashboard.html">
        <img class="mb-4" th:src="@{/img/bootstrap-solid.svg}" alt="" width="72" height="72">
        <h1 class="h3 mb-3 font-weight-normal" th:text="#{login.tip}">Please sign in</h1>
        <label class="sr-only" th:text="#{login.username}">Username</label>
        <input type="text" class="form-control" th:placeholder="#{login.username}" required="" autofocus="">
        <label class="sr-only" th:text="#{login.password}">Password</label>
        <input type="password" class="form-control" th:placeholder="#{login.password}" required="">
        <div class="checkbox mb-3">
            <label>
                <input type="checkbox" value="remember-me" th:text="#{login.remember}">
            </label>
        </div>
        <button class="btn btn-lg btn-primary btn-block" type="submit" >[[#{login.btn}]]</button>
        <p class="mt-5 mb-3 text-muted">© 2017-2018</p>
        <a class="btn btn-sm">中文</a>
        <a class="btn btn-sm">English</a>
    </form>
</body>
12

3.2 实现跟随按钮切换

1.先给两个按钮使用跳转地址

<a class="btn btn-sm" th:href="@{/index.html(l='zh_CN')}">中文</a>
<a class="btn btn-sm" th:href="@{/index.html(l='en_US')}">English</a>

2.自定义国际化组件

可以在config文件夹下创建一个MyLocalResolver

public class MyLocalResolver implements LocaleResolver {

    @Override
    public Locale resolveLocale(HttpServletRequest httpServletRequest) {
        //获取请求中的参数
        String language = httpServletRequest.getParameter("l");
        //如果没有就默认
        Locale locale = Locale.getDefault();
        //如果请求连接携带了国际化参数
        if (!StringUtils.isEmpty(language)){
            String[] l = language.split("_");
            //国家、地区
            locale=new Locale(l[0], l[1]);
        }
        return locale;
    }

    @Override
    public void setLocale(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Locale locale) {
    }
}

3.在MyMvcConfig注册成Bean,使之生效

@Bean
public LocaleResolver localeResolver(){
    return new MyLocalResolver();
}

这样运行软件之后就可以进行点击按钮中英切换

四、登陆页面实现

1.修改index.html

<body class="text-center">
    <!--修改运行路径为 th:action="@{/login}"  /login为Controller类设置路径 -->
    <form class="form-signin" th:action="@{/login}">
        <img class="mb-4" th:src="@{/img/bootstrap-solid.svg}" alt="" width="72" height="72">
        <h1 class="h3 mb-3 font-weight-normal" th:text="#{login.tip}">Please sign in</h1>
        <!--添加的一个错误语句,出现登陆错误可以显示 -->
        <p style="color: red" th:text="${msg}" th:if="${not #strings.isEmpty(msg)}"></p>

        <label class="sr-only" th:text="#{login.username}">Username</label>
        <!--添加name="username",值可以传递到后端 -->
        <input type="text" class="form-control" th:placeholder="#{login.username}" name="username" required="" autofocus="">
        <label class="sr-only" th:text="#{login.password}">Password</label>
        <!--添加name="password",值可以传递到后端 -->
        <input type="password" class="form-control" th:placeholder="#{login.password}" name="password" required="">
        <div class="checkbox mb-3">
            <label>
                <input type="checkbox" value="remember-me" th:text="#{login.remember}">
            </label>
        </div>
        <button class="btn btn-lg btn-primary btn-block" type="submit" >[[#{login.btn}]]</button>
        <p class="mt-5 mb-3 text-muted">© 2017-2018</p>
        <a class="btn btn-sm" th:href="@{/index.html(l='zh_CN')}">中文</a>
        <a class="btn btn-sm" th:href="@{/index.html(l='en_US')}">English</a>
    </form>
</body>

2.编写控制类

@Controller
public class LoginController {

    @RequestMapping("/login")
    public String login(@RequestParam("username") String username, @RequestParam("password") String password, Model model){
        // 具体业务  当username不为空并且密码为123456时可以登录,不然返回错误信息msg
        if (!StringUtils.isEmpty(username)&&password.equals("123456")){
            return "dashboard";
        }else {
            model.addAttribute("msg","用户名或密码错误");
            return "index";
        }
    }
}

3.测试运行

输入错误时:

13

成功登录时:

14

4.路径优化

看上图登录成功页面路径,可以看出,登录参数一览无余;

这样肯定是不安全的,所以我们要进行路径优化

思路:当我们访问 http://localhost:8080/main.html 可以进入主页面

第一步:在MyMvcConfig添加一个main.html的映射

   public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("index");
        registry.addViewController("/index.html").setViewName("index");
        //添加一个main.html的映射
        registry.addViewController("/main.html").setViewName("dashboard.html");
    }

第二步:使登陆成功时,重定向到main.html,修改Controller

public String login(@RequestParam("username") String username, @RequestParam("password") String password, Model model){
    // 具体业务
    if (!StringUtils.isEmpty(username)&&password.equals("123456")){
        //重定向到main.html
        return "redirect:/main.html";

    }else {
        model.addAttribute("msg","用户名或密码错误");
        return "index";
    }
}
15

登陆成功页面成功变换

五、登录拦截器

1.更改Controller类,登录后将username存入session域中

@RequestMapping("/login")
  //  @ResponseBody
    public String login(@RequestParam("username") String username, @RequestParam("password") String password, Model model, HttpSession session){
        // 具体业务
        if (!StringUtils.isEmpty(username)&&password.equals("123456")){
            // 存入session
            session.setAttribute("loginUser",username);
            return "redirect:/main.html";
        }else {
            model.addAttribute("msg","用户名或密码错误");
            return "index";
        }
    }
}

2.在config创建拦截器类

public class LoginHandlerInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

        //登陆成功之后,应该有用户Session
        Object loginUser = request.getSession().getAttribute("loginUser");
        if (loginUser==null){
            //没有登陆
            request.setAttribute("msg","你没有权限,请登录");
            request.getRequestDispatcher("/index.html").forward(request,response);
            return false;
        }
        else {
            return true;
        }
    }
}

3.在MyMvcConfig添加一个拦截器的映射

@Override
public void addInterceptors(InterceptorRegistry registry) {
    // /** 拦截全部资源;不包括 /,/login,/index.html,/css/*,/img/*,/js/* 路径下的资源。
    registry.addInterceptor(new LoginHandlerInterceptor()).addPathPatterns("/**")
        .excludePathPatterns("/","/login","/index.html","/css/*","/img/*","/js/*");
}

六、展示员工列表

6.1 引入员工页面

直接导入的网页里面的跳转链接都是默认自带的,我们需要修改为自己的页面。

一、编写Controller

@Controller
public class EmployeeController {

    @Autowired
    EmployeeDao employeeDao;

    @RequestMapping("/emps")
    public String getAllemployee(Model model){
        Collection<Employee> employees = employeeDao.getEmployees();
        model.addAttribute("emp",employees);
        //新创建了一个emp文件夹,将list.html放里面
        return "emp/list";
    }
}

二、修改侧边栏员工部分的跳转链接

<li class="nav-item">
    <!--	                             th:href="@{/emp}" 运行Controller类方法,跳转list.html    -->
    <a th:class="${active=='list.html'?'nav-link active':'nav-link' }" th:href="@{/emps}" >
        <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-users">
            <path d="M17 21v-2a4 4 0 0 0-4-4H5a4 4 0 0 0-4 4v2"></path>
            <circle cx="9" cy="7" r="4"></circle>
            <path d="M23 21v-2a4 4 0 0 0-3-3.87"></path>
            <path d="M16 3.13a4 4 0 0 1 0 7.75"></path>
        </svg>
        Customers
    </a>
</li>

6.2 准备提取页面

我们可以看出,每个页面的 头部侧边栏 都是重复的,所以我们可以把重复的部分提取出来,直接引入html文件中。

  • 提取文件:th:fragment="xxxxx"
  • 引入文件:th:replace="{xxxx}"**、**th:insert=""

第一步、在templates中创建一个commons文件夹,其中创建commons.html。

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">

<!--	顶部        th:fragment="topbar"    -->
<nav class="navbar navbar-dark sticky-top bg-dark flex-md-nowrap p-0" th:fragment="topbar">
    <a class="navbar-brand col-sm-3 col-md-2 mr-0" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">[[${session.loginUser}]]</a>
    <input class="form-control form-control-dark w-100" type="text" placeholder="Search" aria-label="Search">
    <ul class="navbar-nav px-3">
        <li class="nav-item text-nowrap">
            <a class="nav-link" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">Sign out</a>
        </li>
    </ul>
</nav >



<!--				侧边栏     th:fragment="sidebar"  -->
<nav class="col-md-2 d-none d-md-block bg-light sidebar" th:fragment="sidebar">
    <div class="sidebar-sticky">
        <ul class="nav flex-column">
            <li class="nav-item">
                <a th:class="${active=='main.html'?'nav-link active':'nav-link' }" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">
                    <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>
            ..........中间省略
            <li class="nav-item">
                <a class="nav-link" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">
                    <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-file-text">
                        <path d="M14 2H6a2 2 0 0 0-2 2v16a2 2 0 0 0 2 2h12a2 2 0 0 0 2-2V8z"></path>
                        <polyline points="14 2 14 8 20 8"></polyline>
                        <line x1="16" y1="13" x2="8" y2="13"></line>
                        <line x1="16" y1="17" x2="8" y2="17"></line>
                        <polyline points="10 9 9 9 8 9"></polyline>
                    </svg>
                    Year-end sale
                </a>
            </li>
        </ul>
    </div>
</nav>
</html>

第二步、在其他html页面中把原来的头部、侧边代码删除,并在相同的位置引入

<!--	顶部-->
<div th:replace="~{commons/commons::topbar}"></div>
<!--	侧边栏-->
<div th:replace="~{commons/commons::sidebar}" ></div>

第三步、这里是为了在网页中,点击侧边的哪一个模块、哪一个模块对应的文字亮起来

思路:

  • 跳转时传递一个参数
  • 每个模块的参数用对应的html名字表示
  • 在侧边栏代码中进行判断,对应的名字亮对应的部分

1.添加参数

例如,dashboard.html和list.html页面:

<div th:replace="~{commons/commons::sidebar(active='main.html')}" ></div>
<div th:replace="~{commons/commons::sidebar(active='list.html')}"></div>

2.判断

使用 th:class="${active=='xxx'?'nav-link active':'nav-link' }" 进行判断

6.3 展示员工列表

到了这一步,准备工作基本都完成了,开始在list.html展示

<main role="main" class="col-md-9 ml-sm-auto col-lg-10 pt-3 px-4">
    <h2>Section title</h2>
    <div class="table-responsive">
        <table class="table table-striped table-sm">
            <thead>
                <tr>
                    <th>id</th>
                    <th>lastName</th>
                    <th>email</th>
                    <th>gender</th>
                    <th>department</th>
                    <th>birth</th>
                </tr>
            </thead>
            <tbody th:each="emp:${emps}">
                <tr>
                    <td th:text="${emp.getId()}"></td>
                    <td th:text="${emp.getLastName()}"></td>
                    <td th:text="${emp.getEmail()}"></td>
                    <td th:text="${emp.getGender()==0?'女':'男 '}"></td>
                    <td th:text="${emp.getDepartment().getDepartmentName()}"></td>
                    <td th:text="${#dates.format(emp.getBirth(),'yyyy-mm-dd hh:mm:ss')}"></td>
                    <td>
                        <button class="btn btn-sm btn-primary">编辑</button>
                        <button class="btn btn-sm btn-danger">删除</button>
                    </td>
                </tr>
            </tbody>
        </table>
    </div>
</main>

七、新增员工信息

1.首先写一个跳转到增加页面的方法

@GetMapping("/emp")
public String toAdd(Model model){
    //查出所有部门信息
    Collection<Department> departments = departmentDao.getDepartments();
    model.addAttribute("depts",departments);
    return "emp/add";
}

2.再新增一个add页面,在emp文件夹中:

from表单method要使用post

        data: {
            labels: ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"],
            datasets: [{
                data: [15339, 21345, 18483, 24003, 23489, 24092, 12034],

            }]
        },
        options: {
            scales: {
                yAxes: [{

                    }
                }]
            },
            legend: {
                display: false,
            }
        }
    });
</script>
</body>
</html>

3.编写增加员工Controller类方法

此时使用的路径仍是emp,但是因为是post传递,符合Restful风格。

@PostMapping("/emp")
public String Addemp(Employee employee){
    System.out.println(employee);
    //保存员工信息
    employeeDao.save(employee);
    return "redirect:/emps";
}
17

八、修改员工信息

1.首先写一个跳转到修改页面的方法

    @GetMapping("/emp/{id}")
    public String toUpdateEmp(@PathVariable("id") Integer id, Model model){
        //查出对应数据
        Employee employee = employeeDao.getEmployee(id);
        model.addAttribute("emp",employee);
        //查出所有部门信息
        Collection<Department> departments = departmentDao.getDepartments();
        model.addAttribute("depts",departments);
        return "emp/update";
    }

2.修改list页面中,编辑按钮的跳转路径

<a class="btn btn-sm btn-primary" th:href="@{/emp/}+${emp.getId()}">编辑</a>

注意:这里的 ‘+’ 会报红,不用管

3.再新增一个update页面,在emp文件夹中:

from表单method要使用post

update页面可以直接复制add页面

以下为

内容

<form class="form-horizontal"  th:action="@{/updateEmp}" method="post">
    <input type="hidden" name="id" th:value="${emp.getId()}">
    <div class="form-group">
        <label  class="col-sm-2 control-label">姓名</label>
        <div class="col-sm-10">
            <input th:value="${emp.getLastName()}" type="text" class="form-control" name="lastName" id="lastName" placeholder="lastName">
        </div>
    </div>
    <div class="form-group">
        <label  class="col-sm-2 control-label">邮箱</label>
        <div class="col-sm-10">
            <input th:value="${emp.getEmail()}" type="email" class="form-control" name="email" id="Email" placeholder="Email">
        </div>
    </div>
    <div class="form-group">
        <label  class="col-sm-2 control-label">性别</label>
        <div class="col-sm-10">
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
            <input th:checked="${emp.getGender()==0}" type="radio" class="form-check-input" name="gender"  value="0">
            <label  class="col-sm-2 control-label">女</label>
            <input th:checked="${emp.getGender()==1}" type="radio" class="form-check-input" name="gender" value="1">
            <label  class="col-sm-2 control-label">男</label>
        </div>
    </div>
    <div class="form-group">
        <label  class="col-sm-2 control-label">部门</label>
        <div class="col-sm-10">
            <select class="form-control" name="department.id">
                <option th:selected="${dept.getId()==emp.getDepartment().getId()}" th:each="dept:${depts}" th:text="${dept.getDepartmentName()}" th:value="${dept.getId()}"></option>
            </select>
        </div>
    </div>
    <div class="form-group">
        <label  class="col-sm-2 control-label">日期</label>
        <div class="col-sm-10">
            <input th:value="${#dates.format(emp.getBirth(),'yyyy-MM-dd hh:mm:ss')}" type="text" class="form-control" name="birth" id="birth" placeholder="birth">
        </div>
    </div>
    <div class="form-group">
        <div class="col-sm-offset-2 col-sm-10">
            <button type="submit" class="btn btn-success">提交</button>
        </div>
    </div>
</form>

4.编写修改员工Controller类方法

@PostMapping("/updateEmp")
public String UpdateEmp(Employee employee){
    employeeDao.save(employee);
    return "redirect:/emps";
}
18

九、删除员工信息

1.修改list页面-删除路径

<a class="btn btn-sm btn-danger" th:href="@{/delemp/}+${emp.getId()}">删除</a>

2.修改Controller类

@GetMapping("/delemp/{id}")
public String DelEmp(@PathVariable("id") Integer id){
    employeeDao.delEmployee(id);
    return "redirect:/emps";
}

十、404页面、注销操作

10.1 404页面

404页面是SpringBoot中最简单的功能:

  • templates创建error文件夹
  • 404页面移入其中
  • 搞定!
19

10.2 注销操作

1.编写Controller方法

@RequestMapping("/loginout")
public String loginout(HttpSession session){
    //session.invalidate();
    session.removeAttribute("loginUser");
    return "redirect:index.html";
}

2.修改注销处跳转路径

<nav class="navbar navbar-dark sticky-top bg-dark flex-md-nowrap p-0" th:fragment="topbar">
    <a class="navbar-brand col-sm-3 col-md-2 mr-0" href="http://getbootstrap.com/docs/4.0/examples/dashboard/#">[[${session.loginUser}]]</a>
    <input class="form-control form-control-dark w-100" type="text" placeholder="Search" aria-label="Search">
    <ul class="navbar-nav px-3">
        <li class="nav-item text-nowrap">
                                     <!--跳转路径修改-->
            <a class="nav-link" th:href="@{/loginout}">Sign out</a>
        </li>
    </ul>
</nav >

这样一个CRUD项目基本完成!
