另外给大家分享一下最近使用idea过程中的小小心得，希望对大家有帮助哈~~

intelliJ idea天下最实用技巧

1）去掉代码自动完成的大小写敏感配置

相信有不少同学也曾经像我一样，感觉idea代码提示的时候老是需要对应大小写，非常不方便，而且特别影响开发的效率和心情。比如有一个类叫做AppleClass，当我想要代码提示自动完成这个类的时候，必须要写大写的A才能提示出来，如果要是不区分大小写就好了。这个当然是可以配置的啦。按照下面图片中的配置，去掉复选框中的内容就可以喽。

按照这个方式设置完之后，感觉生产力提升了一倍多呢，这是不要太爽。

2) local history功能

ide的编辑器撤销步数是有限的，当一个文件被频繁修改，然后我们想看这个文件之前的改动，但是撤销太多已经无效了，这时候应该怎么办呢？有人会说使用git就好啦。但是git对没有提交的改动内容是不具备记忆能力的。所以这时候idea的开发工程师已经帮你做好了解决方案。那就是大名鼎鼎的local history！！看看下面的图就一下可以明白如何使用local history啦。

local hitory会列出这个文件每次保存的版本，设置idea会自动保存文件版本，等待你来查看。也只有idea才会开发出这么贴心的功能啦。

3）自定义快捷键

intellij idea默认有不少快捷键，有的人说不要轻易自定义快捷键，这样会导致你自己的开发环境和别人的不同。其实这是一个双刃剑，自己定义的快捷键能更高的提升开发效率，相对而言保持开发环境的统一的需求就轻得多了。

在idea中如何自定义快捷键呢，按照下图设置就可以啦！

比如我会自定定义快捷键来打开各种tab，比如git和提示窗口。这样工作起来效率就非常高啦！

好了，先分享这么多，后续会继续更新~
