接收前端传递的数据，然后封装添加到存有员工信息的数组中
public String adduser(Employee employee){
employeeDAO.save(employee);
System.out.println(employee);
return "redirect:/emps"; //执行完上面的方法，则进行网页的跳转
}网页跳转这一部分，在前面的博文中有着详细的介绍，如果在这里没有看懂可以看之前的内容，进行多多的了解。
/emps实现的功能则是，将员工的全部信息都显示在前端网页中，
添加用户功能的具体步骤
1：员工信息展示，此网页中有一个添加用户信息按纽
2：网页进行跳转，跳转到add添加用户信息的网页中
3：在此网页中，将新添加用户信息填写完整后，则是点击form表单提交按钮
4：表单将内容添加到指定域名的位置，然后执行方法，将信息添加到数组中
5：信息添加完毕之后，则是进行域名跳转
6：此域名就是将数组中所有的用户信息输出到网页中
7：用户信息添加完成
流程
