回复了 zhuwd 创建的主题 iPhone 2022 年了,苹果手机有什么办法可以通话录音吗?
@InkyMountain @Livid 19 楼的个人信息回复可以帮忙删除吗,手机在口袋里误触了输入法的快捷输入。

回复了 ggp1ot2 创建的主题 程序员 有没有前端开发的一些工具、技巧分享?经验类的
webstorm 是前端专用的
@InkyMountain 动画经常出 bug ,上滑返回桌面容易出现非常鬼畜的动画。
屏幕打孔在中间不如左侧舒服,看全屏视频存在感很强。
拍照个人觉得远差于我的备用机 iphonexr 。
手持 k40 回复,目前遇到觉得不舒服的点:
手机边缘非常容易误触,使用 telegram 经常因为误触发一条空白语音出去。

回复了 vipppppp 创建的主题 Python mysql(后端)分页问题
楼上有个地方写错了,new pageinfo()要用查询结果集当参数。

回复了 vipppppp 创建的主题 Python mysql(后端)分页问题
有个叫 pagehelper 的插件.使用前要先在 xml 里配置。

PageHelper.offsetPage(offset, count );
查询 sql 语句;
int total = new PageInfo().getTotal();

我是新手,不了解具体实现,只会使用,可以参考下。
@eccentric 道理我理解,我不会抱捡便宜的侥幸心理,就是疑惑具体多少 k 算合理。
@wly19960911 谢谢你的建议。我目前的打算是尽快用 ssm 做一个小项目出来丰富下简历。spring boot 优先级应该会慢一点。
@Gure 谢谢你的回复。简历提及的技术都是学过的,但是由于快毕业了,为了尽量多掌握点技术,具体的函数名必须依靠 eclipse 提示。xml 标签都是复制好大体框架再根据需要修改细节。
@ericcode,谢谢
地点是杭州

回复了 InkyMountain 创建的主题 Java 初学者,请教下 JDBC 获取 connection 对象的问题
@billlee 你好,我把 url 的参数修改成下面的测试通过了。

useSSL=false&useUnicode=true&useJDBCCompliantTimezOneShift=true&useLegacyDatetimeCode=false&serverTimezOne=UTC

我还要去了解下 ssl 和 timezone 的知识。非常感谢你的帮助!
