用户表 user
实体类:
public class User { /** * 主键id */ private Integer userId; /** * 账号 */ private String username; /** * 密码 */ private String password; public Integer getUserId() { return userId; } public void setUserId(Integer userId) { this.userId = userId; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }
UserMapper
<?xml version="1.0" encoding="UTF-8" ?>
mapper层
public interface UserMapper { User getUserByname(String username); }
service层
public interface UserService { User getUserByname(String username, String password, HttpSession session, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse); }
impl
@Service public class UserServiceImpl implements UserService { @Autowired private UserMapper userMapper; @Override public ResultVO getUserByname(String username, String password, HttpSession session, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) { String remember = httpServletRequest.getParameter("remember"); if (username!= null && username!= 0){ User user = userMapper.getUserByname(username); if (user != null && user.getPassword().equals(password)){ session.setAttribute("user", user); if (remember != null){ Cookie cookieUser = new Cookie("username", username); Cookie cookiePass = new Cookie("password", password); cookieUser.setMaxAge(60 * 60 * 24); cookiePass.setMaxAge(60 * 60 * 24); httpServletResponse.addCookie(cookieUser); httpServletResponse.addCookie(cookiePass); return ResultVO.success(user); } return ResultVO.error(1, "用户名或密码错误"); } return ResultVO.error(3, "用户名或密码不能为空"); } }
Controller
@RestController public class UserController { @Autowired private UserService userService; //登录 @RequestMapping("/getUserByname") public ResultVO getUserByname(String username, String password, HttpSession session, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse){ return userService.getUserByname(username, password, session, httpServletRequest, httpServletResponse); } }
前端代码(JSP)
html的自己修改下,样式是BootStrap的
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ page contentType="text/html;charset=UTF-8" language="java" %>登录
