1、生成密码并入库保存

String id= SnowflakeIdUtil.nextValue();//生成id
operatCompany.setId(id);
String salt = oConvertUtils.randomGen(8);//生成密码盐
operatCompany.setSalt(salt);
String resetPasswd= ConfigManager.getInstance().GetProperty("resetPasswd");//读取配置文件的默认密码
String passwordEncode = PasswordUtil.encrypt(id, resetPasswd, salt);//根据id+密码+密码盐，生成加密密码（这里id可以换成用户名）
operatCompany.setPassword(passwordEncode);
operatCompanyService.save(operatCompany);

2、验证密码完成登录

//2. 校验用户名或密码是否正确
String userpassword = PasswordUtil.encrypt(id, password, db_salt);
if (!db_password.equals(userpassword)) {
    result.error500("用户名或密码错误");
    return result;
}

3、密码修改

String passwordEncode = PasswordUtil.encrypt(os.getId(), password, os.getSalt());
operatStaffService.update(new OperatStaff().setPassword(passwordEncode),new LambdaQueryWrapper<OperatStaff>().eq(oConvertUtils.isNotEmpty(username),OperatStaff::getMobile, username));
