设置以Java结尾的默认行 [英] Set default line ending in Java
问题描述
我在多平台环境（Windows + Linux）中使用Java。但是，无论我们生成什么文本文件，都应使用LF作为其EOL序列。
I'm working with Java in a multi-platform environment (Windows + Linux). Whatever text files we produce, however, should use LF as their EOL sequence.
我是否可以强制Java使用此EOL序列，无论我在运行程序的平台上如何？我不想改变整个程序，即所有对System.out.println和类似程序的调用都应保持原样，只有函数末尾的* ln应该总是输出0x0A并且永远不会 0x0D 0x0A。
Is there a way I can force Java to use this EOL sequence regardless on the platform I'm running a program on? I'd like not to have to change the whole program, i.e. all calls to System.out.println and similar should be kept as is, only the *ln at the end of the function should always output an "0x0A" and never "0x0D 0x0A".
我可以想到两种不同的方式，但我不知道是否有可能：
I could think of two different ways of doing that, but I don't know if either one is possible:
- 覆盖平台相关的默认EOL序列
- 使Java相信即使我在DOS命令行上运行程序，我也在运行Linux
这有可能吗？或者其他什么呢？
Is any of this possible? Or something else perhaps?
推荐答案
您可以尝试设置相应的系统属性，如 System.setProperty（ line.separator，你需要的东西）; （它也可以通过命令行参数实现到JVM）
You can try setting the corresponding system property like System.setProperty("line.separator", "something you need"); (It can also be achieved throug command-line parameters to JVM)
或者，也许，您可以使用打印 insetad println 并打印换行符（\\ \\ r，\ n或他们的组合）你需要的地方。
Or, maybe, you can use print insetad of println and print line-breaking characters ("\r", "\n" or their combination) where you need it.
