@Aruforce 那你是不是有倾向用 vs code 写 java 啊，为啥 IDE 的各种智能提示及补全你不用？

@shayang888 windows 个性化里面把颜色改了就行啊，这个颜色来自于一张壁纸 http://wx3.sinaimg.cn/mw690/0060lm7Tly1fxvlfzc0npj31hc0u0qc2.jpg

这个官方应该不会做吧，感觉意义不大，有多少人这么在意主题切换，一般就一个主题用到底。。
这个插件 [Material Theme UI]( https://plugins.jetbrains.com/plugin/8006-material-theme-ui) 就有亮暗，然后在 toolbar 里面有几个按钮，一点就能切换，不如把这个提议发给这个插件开发者~

怎么个卡死法？ jstack 看看线程们都在干什么

只有一个 200G 盘单分区的路过

这全是习惯而已吧，比如 java 里面包名一般都又臭又长，但是大家虽然吐槽但是还都遵守这样的规则，开发过程中如何在 navigate 中展示就有两种风格

https://ws1.sinaimg.cn/large/af91b397ly1fxj63xrlhrj20bg0e8my2.jpg

上 hierarchy 下 flat，分别对应 java 两种常用的配置文件 properties 和 yaml 格式，喜欢哪种就用哪种

https://ws1.sinaimg.cn/large/af91b397ly1fxj64pqdwzj20a50didgf.jpg

像 yaml 这样的需要配置复杂了才能展示其优点吧，配置项那么短的话好像没啥明显优势。
就像 python 包名那么短的话上面两种视图也没啥大的区别了。

INI 不怎么用，搭建 openstack 的时候用得比较多没觉得 ini 多先进呀 0.0

问题解决了，我之前把 groovy plugin 干掉了（又不写 groovy ），再安装上就可以了。

@syhsyh9696 是个小飞度 fit ~

一般情况遇不到冲突……偶尔冲突时先按下 Enter 把已经输入的发过去，然后 ctrl + space 切输入法就继续工作了，一直以来也没觉得有多大问题，就是帮同事调程序时搜狗拼音很烦，他们连英文输入法都不开不知道怎么忍过来的 0.0
（ ps：我的是精灵五笔，给五笔用户推荐一下）

不知道为啥 Hibernate 这么招黑，很多用 Mybatis 开发发现 sql 生成太麻烦，然后加代码生成器插件，还有的用动态的 mapper，为了性能再配个缓存，这样搞和 Hibernate 有多大区别。。这不是屠龙少年的故事么？ 0.0

对于 [简单的 CRUD] 来说 Hibernate 开发效率很高啊，而且和缓存深度结合的，为啥不尝试一下 Hibernate，当你拒绝一个东西的时候你就少了一条路 0.0

像那种银行啊、考勤啊那种随便一个查询就关联 N 个表的查询业务场景 mybatis 还是非常适合的。

对于那种 cud 都喜欢写 sql 的推荐去写 php，一杆子捅到数据库？（逃

这么想控制每一行代码每一个细节，肯定是处于自己对于技术的不自信~（我也是不自信，希望以后能做到大剑无锋

其他列是什么类型的？试试原生的 PreparedStatement/RestulSet ？
再就是 in 查询一般返回多行为啥用 map 接，怎么也得上个 list 吧？

@5CanTell 蛤蛤蛤蛤，我没有

@5CanTell 撞头像了我滴哥

就像英文有 26 个字母一样吧…………哎？
你去看看 ASCII 表，8 位是能满足表示 26 个字母的前提下最 2^n 最小的了，还多出来一些可以设定成其他符号。
还可能跟早期电脑 CPU 就是 8 位 16 位的有关。
// 嗯。。我不对自己说的话负责。。

@Zhongwei 倒是一直没关注过官方的通知……哎

@heyufei1996 我先反馈的巨硬再来的论坛，主要是这个 bug 也太大了不是吗？
