ProviderServiceImpl providerService;
@Autowired
BillServiceImpl billService;
@RequestMapping(value="/login.do",method = {RequestMethod.POST, RequestMethod.GET})
public String doPost(HttpServletRequest request, HttpServletResponse response, Model model){
System.out.println("login ============ " );
//获取用户名和密码
String userCode = request.getParameter("userCode");
String userPassword = request.getParameter("userPassword");
System.out.println(userCode+" "+userPassword);
//调用service方法,进行用户匹配
User user = userService.login(userCode,userPassword);
System.out.println(user);
if(null != user){//登录成功
//放入session
request.getSession().setAttribute(Constants.USER_SESSION, user);
//页面跳转(frame.jsp)

//页面跳转(login.jsp)带出提示信息--转发
model.addAttribute("error", "用户名或密码不正确");
