接上一节。
在EmployeeController.java中添加
//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"; }
在EmployeeDao.java中添加
private static Integer initId = 1006; public void save(Employee employee){ if(employee.getId() == null){ employee.setId(initId++); } employee.setDepartment(departmentDao.getDepartment(employee.getDepartment().getId())); employees.put(employee.getId(), employee); }

启动服务器：
点击新增跳转到添加员工界面，输入相关信息，注意，springboot默认使用的日期格式是：yyyy/MM/dd，即以“/” 进行分隔。点击添加：
我们也可以在主配置文件中进行格式的更改：
spring.mvc.date-format=yyyy-MM-dd HH:mm
新增功能也就完成了。
