接上文【WEEK11】【DAY3】员工管理系统第四部分【中文版】

10.6.增加员工

10.6.1.修改list.html

第53行，把<h2>Section title</h2>修改成添加员工的按钮
在这里插入图片描述

<h2><a class="btn btn-sm btn-success" th:href="@{/emp}">添加员工</a></h2>

10.6.2.修改EmployeeController.java

添加新方法

package com.P14.controller;

import com.P14.dao.DepartmentDao;
import com.P14.dao.EmployeeDao;
import com.P14.pojo.Department;
import com.P14.pojo.Employee;
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.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.Collection;

@Controller
public class EmployeeController {
    //查询所有员工
    @Autowired
    EmployeeDao employeeDao;
    @Autowired  //自动注入
    DepartmentDao departmentDao;

    @RequestMapping("/emps")    //只要dashboard.html请求了th:href="@{emps}（line89）则跳转到运行@RequestMapping("/emps")
    public String list(Model model){    //然后会查询所有员工，此时再修改：如何显示到前端页面
        Collection<Employee> employees = employeeDao.getAll();
        model.addAttribute("emps",employees);
        return "emp/list";
    }

    @GetMapping("/emp") //get请求获取跳转
    public String toAddpage(Model model){
        //查出所有部门的信息
        Collection<Department> departments = departmentDao.getDepartment();
        model.addAttribute("departments",departments);
        return "emp/add";
    }

    @PostMapping("/emp")
    public String addEmp(Employee employee){
        //添加的操作 forward
        System.out.println("save=>"+employee);
        employeeDao.save(employee); //调用底层业务方法保存员工信息
        return "redirect:/emps";    //在“添加员工”页面点击“添加”后重定向到“员工管理”页面
    }
}

10.6.3.新建add.html

在这里插入图片描述
和list.html相比，只需要修改<main>内包含的内容

<body>
   <div th:replace="~{common/commons::topbar}"></div>
   <!--改为插入commons.html中的topbar部分-->
   <div class="container-fluid">
      <div class="row">
         <div th:replace="~{common/commons::sidebar(active='list.html')}"></div>
         <!--改为插入commons.html中的sidebar部分-->
         <main role="main" class="col-md-9 ml-sm-auto col-lg-10 pt-3 px-4">
            <form th:action="@{/emp}" method="post">
               <div class="form-group">
                  <label>LastName</label>
                  <input type="text" name="lastName" class="form-control" placeholder="海绵宝宝">
               </div>
               <div class="form-group">
                  <label>Email</label>
                  <input type="email" name="email" class="form-control" placeholder="987654321@qq.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">女</label>
                  </div>
               </div>
               <div class="form-check form-check-inline">
                  <input class="form-check-input" type="radio" name="gender" value="0">
                  <label class="form-check-label">男</label>
               </div>
               <div class="form-group">
                  <label>department</label>
                  <select class="form-control" name="department.id">
                     <!--我们在controller接收的是一个Employee，所以我们需要提交的是其中的一个属性(department.id)-->
                     <option th:each="dept:${departments}" th:text="${dept.getDepartmentName()}" th:value="${dept.getId()}"></option>
                  </select>
               </div>
               <div class="form-group">
                  <label>Birth</label>
                  <input type="text" name="birth" class="form-control" placeholder="2020/07/25 18:00:00">
               </div>
               <button type="submit" class="btn btn-primary">添加</button>
            </form>
         </main>
      </div>
   </div>

   ...

</body>
