如何在Java应用程序中强制使用Windows行结尾？ [英] How do I force Windows line endings in Java app?

问题描述

我有一个Java应用程序写入文件：

  BufferedWriter bw = new BufferedWriter（new FileWriter（outputFile） ）; 
 bw.write（line + lineTermination）; 
  

行终止定义为：

  \\\ n 
  

我变得奇怪，神秘空白行插入到我的文件中。

如果我将代码更改为：

<$ p $我没有额外的行p> bw.write（线）;
bw.newLine（）;


但是我想强制特定的行结束，而不是使用System属性。客户特别要求一个行结束字符 - 有些甚至有|。它不是一个可行的解决方案，只需使用\ n。

以下是缺少行的数据片段：

  KABE， 14/01/11， 14时35分， 14点56分， 1987， 美国， SS，CO ，与孩子结婚，，EINE SCHRECKLICH NETTE FAMILIE，，N，10，，12，O'NEILL ED，13，SAGAL KATEY 
 
PRO7，14/01/11，14:35，14：55，2001，US，SS，CO， SCRUBS，，SCRUBS DIE ANFAENGER，，C，10，BERNSTEIN ADAM，12，BRAFF ZACH，13，CHALKE SARAH

解决方案

你可以打电话

  System.setProperty（line.separator，\\\\ n ）; 
  

以便在代码中设置系统属性。

I have a Java app that writes to a file with:

BufferedWriter bw = new BufferedWriter(new FileWriter(outputFile));
bw.write(line + lineTermination);

Line termination is defined as:

\r\n

I get the odd, mysterious blank line inserted into my file.

I get no extra lines if I change my code to:

bw.write(line);
bw.newLine();

But I want to force a specific line ending, not use System property. Clients specifically request a line ending character - some even have |. Its not a viable fix to just use \n.

Here is an snippet of the data with missing line:

"KABE","14/01/11","14:35","14:56","1987","US","SS","CO","MARRIED WITH CHILDREN","","EINE SCHRECKLICH NETTE FAMILIE","","N","10","","12","O'NEILL ED","13","SAGAL KATEY"

"PRO7","14/01/11","14:35","14:55","2001","US","SS","CO","SCRUBS","","SCRUBS DIE ANFAENGER","","C","10","BERNSTEIN ADAM","12","BRAFF ZACH","13","CHALKE SARAH"

Thanks for your time :-)

解决方案

You can call

System.setProperty("line.separator", "\r\n");

in order to set the system property inside your code.
