背景
有的时候我们做框架升级或改造的时候，需要用到原来的部分表，比如只是用ruoyi的框架，然后登录的用户逻辑还是想用自己的表，那么接下来这边文章将介绍修改逻辑。
修改教程
1、SysLoginController.java
大家找到这个login方法，这是controller的入口。
/*** 登录方法* * @param loginBody 登录信息* @return 结果*/@PostMapping("/login")public AjaxResult login(@RequestBody LoginBody loginBody){// 退出接口查看LogoutSuccessHandlerImpl.onLogoutSuccessAjaxResult ajax = AjaxResult.success();// 生成令牌，修改这个map返回自己的表的用户对象。// 如果这里不处理其余的逻辑就不需要修改，因为我这里要手动写入自己的日志Map<String, Object> map = loginService.login(loginBody.getUsername(), loginBody.getPassword(), loginBody.getCode(),loginBody.getUuid());LoginUser loginUser = (LoginUser)map.get("loginUser");loginUser.setLanguage(loginBody.getLanguage());bsOperateLogV2Service.createLoginLog(String.valueOf(loginUser.getUserId()),loginUser.getUsername(),1,String.valueOf(loginUser.getDeptId()));ajax.put(Constants.TOKEN, map.get("token"));return ajax;}2、SysLoginService.java
这里有一些验证，比如验证码，用户是否存在等，大家点击进入到loginPreCheck方法中，把查询用户修改为自己的表查询，然后把没有用的逻辑注释掉。
/*** 登录验证* * @param username 用户名* @param password 密码* @param code 验证码* @param uuid 唯一标识* @return 结果*/public Map<String, Object> login(String username, String password, String code, String uuid){// 验证码校验validateCaptcha(username, code, uuid);// 登录前置校验loginPreCheck(username, password);// 用户验证Authentication authentication = null;try{UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(username, password);AuthenticationContextHolder.setContext(authenticationToken);// 该方法会去调用UserDetailsServiceImpl.loadUserByUsernameauthentication = authenticationManager.authenticate(authenticationToken);}catch (Exception e){if (e instanceof BadCredentialsException){//AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_FAIL, MessageUtils.message("user.password.not.match")));throw new UserPasswordNotMatchException();}else{//AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_FAIL, e.getMessage()));throw new ServiceException(e.getMessage());}}finally{AuthenticationContextHolder.clearContext();}//AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_SUCCESS, MessageUtils.message("user.login.success")));LoginUser loginUser = (LoginUser) authentication.getPrincipal();//recordLoginInfo(loginUser.getUserId());Map<String, Object> map = new HashMap<>();map.put("token",tokenService.createToken(loginUser));map.put("loginUser",loginUser);// 生成tokenreturn map;}/*** 登录前置校验* @param username 用户名* @param password 用户密码*/public void loginPreCheck(String username, String password){// 用户名或密码为空 错误if (StringUtils.isEmpty(username) || StringUtils.isEmpty(password)){AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_FAIL, MessageUtils.message("not.null")));throw new UserNotExistsException();}// 密码如果不在指定范围内 错误
// if (password.length() < UserConstants.PASSWORD_MIN_LENGTH
// || password.length() > UserConstants.PASSWORD_MAX_LENGTH)
// {
// AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_FAIL, MessageUtils.message("user.password.not.match")));
// throw new UserPasswordNotMatchException();
// }
// // 用户名不在指定范围内 错误
// if (username.length() < UserConstants.USERNAME_MIN_LENGTH
// || username.length() > UserConstants.USERNAME_MAX_LENGTH)
// {
// AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_FAIL, MessageUtils.message("user.password.not.match")));
// throw new UserPasswordNotMatchException();
// }
// // IP黑名单校验
// String blackStr = configService.selectConfigByKey("sys.login.blackIPList");
// if (IpUtils.isMatchedIp(blackStr, IpUtils.getIpAddr()))
// {
// AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_FAIL, MessageUtils.message("login.blocked")));
// throw new BlackListException();
// }}3、loadUserByUsername方法
大家找到UserDetailsServiceImpl.loadUserByUsername方法，这是核心。
@Overridepublic UserDetails loadUserByUsername(String username) throws UsernameNotFoundException{Authentication usernamePasswordAuthenticationToken = AuthenticationContextHolder.getContext();
// 这是自己的页面输入的密码，没有加密，比如123456String inputPassword = usernamePasswordAuthenticationToken.getCredentials().toString();// 这里是自定义的表查询，用户和密码验证，如果还有其他的验证都可以在这里进行添加LambdaQueryWrapper wrapper = new LambdaQueryWrapper<BladeUserV2DO>().eq(BladeUserV2DO::getAccount,username)//PasswordUtil是自己的加密工具，你用什么加密就保持原来的就行.eq(BladeUserV2DO::getPassword, PasswordUtil.encrypt(inputPassword)).eq(BladeUserV2DO::getIsDeleted,0);// 这里写自己的登录验证逻辑BladeUserV2DO bladeUserV2DO = bladeUserV2Mapper.selectOne(wrapper);
// SysUser user = userService.selectUserByUserName(username);if (StringUtils.isNull(bladeUserV2DO)){log.info("登录用户：{} 不存在.", username);throw new UserPasswordNotMatchException();}BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();// 这里一定要把加密后的密码放进去，后面的验证中会一直用这个密码// 这个是123456加密后的密码，这里给框架都是完全通过的密码，// 因为我们在方法开始的时候自己进行密码验证，能走到这里都是验证通过的bladeUserV2DO.setPassword(passwordEncoder.encode(inputPassword));passwordService.validate(bladeUserV2DO);return createLoginUser(bladeUserV2DO);}public UserDetails createLoginUser(BladeUserV2DO bladeUserV2DO){BladeUserRespVo bladeUserRespVo = bladeUserV2Mapper.getBladeUserInfo(bladeUserV2DO.getId());SysUser user = new SysUser();user.setUserId(bladeUserV2DO.getId());user.setDeptId(0L);if(StringUtils.isNotEmpty(bladeUserV2DO.getDeptId())){user.setDeptId(Long.parseLong(bladeUserV2DO.getDeptId()));}user.setEmail(bladeUserV2DO.getEmail());user.setDelFlag("0");user.setNickName(bladeUserV2DO.getRealName());user.setUserName(bladeUserV2DO.getAccount());user.setPhonenumber(bladeUserV2DO.getPhone());user.setCreateTime(bladeUserV2DO.getCreateTime());user.setRoleId(0L);// 必须复制加密后的密码，后续框架一直在验证// 上面已经把123456对应的加密字符串保存进来，这里直接复制进去// 后续的框架一直在验证user.setPassword(bladeUserV2DO.getPassword());if(StringUtils.isNotEmpty(bladeUserV2DO.getRoleId())){user.setRoleId(Long.parseLong(bladeUserV2DO.getRoleId()));}user.setSex(bladeUserV2DO.getSex()+"");// LoginUser直接修改代码，把自己需要添加的字段都写进去，生成对应的set和get方法就行return new LoginUser(user.getUserId(), user.getDeptId(),user, permissionService.getMenuPermission(user),bladeUserRespVo.getIsSuperAdmin(),bladeUserRespVo.getIsAdmin(),bladeUserV2DO.getAccount());}public LoginUser(Long userId, Long deptId, SysUser user, Set<String> permissions,int isSuperAdmin,int isAdmin, String account){this.userId = userId;this.deptId = deptId;this.user = user;this.permissions = permissions;//增加自己的字段this.isSuperAdmin = isSuperAdmin;this.isAdmin = isAdmin;this.account = account;}4、SysPasswordService.java
这里的validate方法中，把没有用的逻辑注释掉。
/*** 登录账户密码错误次数缓存键名* * @param username 用户名* @return 缓存键key*/private String getCacheKey(String username){return CacheConstants.PWD_ERR_CNT_KEY + username;}public void validate(BladeUserV2DO bladeUserV2DO){Authentication usernamePasswordAuthenticationToken = AuthenticationContextHolder.getContext();String username = usernamePasswordAuthenticationToken.getName();String password = usernamePasswordAuthenticationToken.getCredentials().toString();
// Integer retryCount = redisCache.getCacheObject(getCacheKey(username));
//
// if (retryCount == null)
// {
// retryCount = 0;
// }
//
// if (retryCount >= Integer.valueOf(maxRetryCount).intValue())
// {
// AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_FAIL,
// MessageUtils.message("user.password.retry.limit.exceed", maxRetryCount, lockTime)));
// throw new UserPasswordRetryLimitExceedException(maxRetryCount, lockTime);
// }if (!matches(bladeUserV2DO, password)){
// retryCount = retryCount + 1;
// AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_FAIL,
// MessageUtils.message("user.password.retry.limit.count", retryCount)));
// redisCache.setCacheObject(getCacheKey(username), retryCount, lockTime, TimeUnit.MINUTES);throw new UserPasswordNotMatchException();}else{clearLoginRecordCache(username);}}5、PasswordUtil.java
如果你用的md5加密就不需要我的这个工具类
