service 横向传递数据 校验数据

public Boolean updatePhone(String token, String newPhone) {

//校验token

User user = this.userService.queryUserByToken(token);

}

}

return result;

}

=========================================================

service

public Boolean updatePhone(Long userId, String newPhone) {

//先查询新手机号是否已经注册，如果已经注册，手机手机就不能修改

QueryWrapper<User> queryWrapper = new QueryWrapper<>();

queryWrapper.eq("mobile",号参号 newPhone);

User user = this.userMapper.selectOne(queryWrapper);

if(ObjectUtil.isNotEmpty(user)){

//新手机号已经被注册

return false;

}

user = new User();

user.setId(userId);

user.setMobile(newPhone);

return this.userMapper.updateById(user) > 0;
