Intellij重新格式化文件保存
本文翻译自：Intellij reformat on file save
I remember seeing in either IntelliJ or Eclipse the setting to reformat (cleanup) files whenever they are saved. 我记得在IntelliJ或Eclipse中看到了保存时重新格式化（清理）文件的设置。 How do I find it (didn't find it in the settings) 我如何找到它（没有在设置中找到它）

Ctrl + Alt + L is format file (includes the two below) Ctrl + Alt + L是格式文件（包括下面两个）
Ctrl + Alt + O is optimize imports Ctrl + Alt + O可以优化导入
Ctrl + Alt + I will fix indentation on a particular line Ctrl + Alt + 我将修复特定行的缩进
I usually run Ctrl + Alt + L a few times before committing my work. 我通常在执行工作之前运行Ctrl + Alt + L几次。 I'd rather it do the cleanup/reformatting at my command instead of automatically. 我宁愿它在我的命令而不是自动执行清理/重新格式化。

I wound up rebinding the Reformat code... action to Ctrl - S , replacing the default binding for Save All . 我将重新格式Reformat code...重新绑定Reformat code...操作到Ctrl - S ，替换Save All的默认绑定。
It may sound crazy at first, but IntelliJ seems to save on virtually every action: running tests, building the project, even when closing an editor tab. 起初听起来可能很疯狂，但IntelliJ似乎几乎可以节省每一个动作：运行测试，构建项目，甚至关闭编辑器选项卡。 I have a habit of hitting Ctrl - S pretty often, so this actually works quite well for me. 我有一个经常按Ctrl - S的习惯，所以这对我来说确实很有用。 It's certainly easier to type than the default bind for reformatting. 输入肯定比重新格式化的默认绑定更容易。

Below is Neil's answer updated. 以下是Neil的答案更新。
IntelliJ 13 Steps: IntelliJ 13步骤：
- Code -> Reformat Code 代码 - >重新格式化代码
- Edit -> Macros -> Start Macro Recording 编辑 - >宏 - >开始宏录制
- Code -> Reformat Code 代码 - >重新格式化代码
- File -> Save all 文件 - >全部保存
- Edit -> Macros -> Stop Macro Recording 编辑 - >宏 - >停止宏录制
- Name the macro (something like "formatted save") 命名宏（类似“格式化保存”）
- File -> Settings -> Keymap 文件 - >设置 - >键盘映射
- Right click on the macro. 右键单击宏。 Add Keyboard Shortcut. 添加键盘快捷键。 Set the keyboard shortcut to Control + S. 将键盘快捷键设置为Control + S.

I suggest the save actions plugin . 我建议保存动作插件 。 It also supports optimize imports and rearrange code. 它还支持优化导入和重新排列代码。
Works well in combination with the eclipse formatter plugin . 与eclipse格式化程序插件结合使用效果很好。
Search and activate the plugin: 搜索并**插件：
Configure it: 配置它：
Edit: it seems like it the recent version of Intellij the save action plugin is triggered by the automatic Intellij save. 编辑：似乎最近版本的Intellij保存动作插件是由自动Intellij保存触发的。 This can be quite annoying when it hits while still editing. 当它仍然在编辑时命中时，这可能非常烦人。
This github issue of the plugin gives a hint to some possible solutions: 这个插件的github问题提供了一些可能的解决方案的提示：

I actually tried to assign reformat to Ctrl + S and it worked fine - saving is done automatically now. 我实际上尝试将重新格式化为Ctrl + S并且工作正常 - 现在自动完成保存。
