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);
    }
