控制层

@Controller("departmentController")
public class DepartmentController {
    //业务层
    @Autowired
    private DepartmentService departmentService;

    //规则  /department/list.do     /department_list.jsp

        //查找全部
        List list = departmentService.getAll();
        request.setAttribute("LIST",list);
        request.getRequestDispatcher("../department_list.jsp").forward(request,response);
    }

    public void toAdd(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        request.getRequestDispatcher("../department_add.jsp").forward(request,response);
    }

    //修改
    public void toEdit(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        //1获取ID
        Integer id = Integer.parseInt(request.getParameter("id"));
        //2.方法
        Department department = departmentService.get(id);
        request.setAttribute("OBJ",department);

        String address = request.getParameter("address");

        //实例化
        Department department = new Department();
