IntelliJ Idea设置默认换行符 Configuring Line Separators
IntelliJ换行CRLF, LF, CR的解释和默认设置
在window下开发有一个大坑,就是换行默认是CRLF,也就是回车换行,但是Linux下只有换行LF,这样代码提交后,会出现编译问题,所以最好的办法是在IntelliJ下设置默认为LF。首先我们先介绍CRLF,LF和CR这三种东西,CR是MAC老版本的做法,就是回车,但是后来的MAC系统统一换成LF了,LF是Linux下的做法,就是换行,这个做法比较自然,为什么要回车换行呢,是吧。微软采用的是CRLF,看上去好像是兼容了CR和LF,但是实际完全不是那么回事,就是回车并换行,好鸡肋啊,微软一直保持这种做法,开发人员大多在Linux下,所以对于开发人员来说还是比较坑的。下面介绍设置详解:
###第一步:File->Other Settings->Default Settings
###第二步:Editor->Code Style
可以看到,默认是System-Dependent,这个其实还是很牛叉的,根据系统自动配置,但是你是windows系统,默认是CRLF,服务器是Linux,你就得自己换了。
我们设置成下面这样,保存就好了
创建文件时,就能看到默认是LF了
参考网址是IntelliJ的使用,不熟悉的话,可以看看,这个文档还是写的不错的,就是全是英文,对于英文不好的人来说,略坑。

IntelliJ IDEA makes it possible to set up line separators (line endings) for the newly created files, and change line separator style for the existing files.
On this page:
- Setting up line separators for newly created files
- Viewing line ending style for the current file
- Changing line separator for a file, currently opened in the editor
- Changing line separator for a selection in the Project view
- Tips and tricks
To set up line separators for new files
- In Settings, click Code Style.
- From the Line separator (for new files) drop-down list, select the desired line separator style:
- Apply changes and close the dialog.
To view line ending style for the current file
- Open the desired file in the editor, as described in the section Opening and Reopening Files.
- View the Status bar: the current line endings style is denoted by the dedicated icon with the specified style, for example, .
To change line separator for a file, currently opened in the editor
- Open the desired file in the editor, as described in the section Opening and Reopening Files.
- Do one of the following:
-
Click the line separator spin box in the Status bar, and choose the desired line ending style from the pop-up menu:
- Choose
-
Click the line separator spin box in the Status bar, and choose the desired line ending style from the pop-up menu:
To change line separator for a file or directory, selected in the Project view
Select a file or directory in the Project tool window.
Note that if a directory is selected, the line ending style applies to all nested files recursively.
Choose
Tips and tricks
- Use multiple selection in the Project view.
- Changing line separator is reflected in the Local history of a file.
- Run the inspection 'Inconsistent line separators' to find out, which files use line separator different from project's default.
