admin登錄

導入Bcrypt依賴
用於加密解密用戶密碼

            <!-- https://mvnrepository.com/artifact/org.mindrot/jbcrypt -->
            <dependency>
                <groupId>org.mindrot</groupId>
                <artifactId>jbcrypt</artifactId>
                <version>0.4</version>
            </dependency>

基本和之前的手機號校驗登錄差不多 換湯不換葯
用戶登錄流程:

1. 首先判斷字段是否合法 若不合法直接拋出異常
2. 根據用戶名查詢是否有記錄 若無記錄直接返回
3. 使用Bcrypt算法校驗用戶密碼是否匹配 若匹配將設置cookie和redis並返回ok 若不匹配返回error

BCrypt.checkpw() 用戶校驗用戶密碼 若密碼匹配則返回true

controller

public GraceJSONResult adminLogin(AdminLoginVO adminLoginVO,
                                      HttpServletRequest request,
                                      HttpServletResponse response,
                                      BindingResult bindingResult) {
        // 1. 首先查詢字段是否合法
        if (bindingResult.hasErrors()) {
            Map<String, String> bindResultErrors = super.getBindResultErrors(bindingResult);

            return GraceJSONResult.errorMap(bindResultErrors);
        }

        // 2. 首先根據用戶名查詢 用戶在database中是否有記錄
        AdminUser usernameByAdmin = adminService.findUsernameByAdmin(adminLoginVO.getUsername());
        if (usernameByAdmin == null) {
            return GraceJSONResult.errorCustom(ResponseStatusEnum.ADMIN_NOT_EXIT_ERROR);
        }

        // 3. 查看用戶名密碼是否匹配
        boolean flag = BCrypt.checkpw(adminLoginVO.getPassword(), usernameByAdmin.getPassword());

        if (flag) {
            String token = UUID.randomUUID().toString();
            setCookie(request, response, "atoken", token, COOKIE_AGE);
            setCookie(request, response, "aid", usernameByAdmin.getId(), COOKIE_AGE);
            setCookie(request, response, "aname", usernameByAdmin.getAdminName(), COOKIE_AGE);

            redisOperator.set(REDIS_ADMIN_TOKEN + ":" + usernameByAdmin.getId(), token);

            return GraceJSONResult.ok();
        } else {
         return GraceJSONResult.errorCustom(ResponseStatusEnum.ADMIN_NOT_EXIT_ERROR);
        }
    }

service直接調用mapper 根據用戶名查詢用戶並返回

    public AdminUser findUsernameByAdmin(String username) {
        QueryWrapper<AdminUser> adminUserQueryWrapper = new QueryWrapper<>();

        adminUserQueryWrapper.eq("username", username);

        return adminMapper.selectOne(adminUserQueryWrapper);
    }
