Personnel management system --第六天

增加员工

public void toAdd(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        List<Department> departments=departmentService.getAll();
        request.setAttribute("departments",departments);                                                          //用于页面的显示，不用管
        request.getRequestDispatcher("../staff_add.jsp").forward(request,response);
    }
    public void add(HttpServletRequest request, HttpServletResponse response) throws IOException {
        String account=request.getParameter("account");
        String did=request.getParameter("did");
        String name=request.getParameter("name");
        String sex=request.getParameter("sex");
        String idNumber=request.getParameter("idNumber");
        Date bornDate=null;
        try {
            bornDate=new SimpleDateFormat("yyyy-MM-dd").parse(request.getParameter("bornDate"));
        } catch (ParseException e) {
            e.printStackTrace();
        }
        String info=request.getParameter("info");
        Staff staff=new Staff();
        staff.setAccount(account);
        staff.setDid(Integer.parseInt(did));
        staff.setName(name);
        staff.setSex(sex);
        staff.setIdNumber(idNumber);
        staff.setBornTime(bornDate);
        staff.setInfo(info);
        staffService.add(staff);
        response.sendRedirect("list.do");
    }

删除员工

public void remove(HttpServletRequest request, HttpServletResponse response) throws IOException {
        String id=request.getParameter("id");
        staffService.remove(Integer.parseInt(id));
        response.sendRedirect("list.do");
    }

要点：new SimpleDateFormat对象：将String类型转换为Date类

编辑（修改）员工信息

public void toEdit(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String id=request.getParameter("id");
        Staff staff=staffService.get(Integer.parseInt(id));
        List<Department> departments=departmentService.getAll();
        request.setAttribute("staff",staff);
        request.setAttribute("departments",departments);
        request.getRequestDispatcher("../staff_edit.jsp").forward(request,response);
    }
    public void edit(HttpServletRequest request, HttpServletResponse response) throws ParseException, IOException {
        String id=request.getParameter("id");
        String account=request.getParameter("account");
        String did=request.getParameter("did");
        String name=request.getParameter("name");
        String sex=request.getParameter("sex");
        String idNumber=request.getParameter("idNumber");
        String info=request.getParameter("info");

        Staff staff=staffService.get(Integer.parseInt(id));
        staff.setAccount(account);
        staff.setDid(Integer.parseInt(did));
        staff.setName(name);
        staff.setSex(sex);
        staff.setIdNumber(idNumber);
        Date bornDate=null;
        try {
            bornDate=new SimpleDateFormat("yyyy-MM-dd").parse(request.getParameter("bornDate"));
        } catch (ParseException e) {
            e.printStackTrace();
        }
        staff.setBornTime(bornDate);
        staff.setInfo(info);
        staffService.edit(staff);
        response.sendRedirect("list.do");
    }

显示员工信息：

public void detail(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String id=request.getParameter("id");
        Staff staff=staffService.get(Integer.parseInt(id));
        request.setAttribute("staff",staff);
        request.getRequestDispatcher("../staff_detail.jsp").forward(request,response);
    }
