Java属性，获取文件路径 [英] Java Properties, getting file path

问题描述

logpath = LoggerUtils.getProperties().getProperty("log.path");
System.out.println("logpath: " + logpath);

上面的代码返回:

logpath: C:UsersMauriceDesktopLogs

在属性文件中是:

log.path    C:\Users\Maurice\Desktop\Logs

如何保留文件分隔符?我希望它也可以在Linux上运行，而不仅仅是Windows.

How do I retain the file separators? I want this to work on Linux as well and not just Windows.

推荐答案

实际上，您需要将其放在属性文件中:

Actually, you need to put this in the property file:

log.path    C:\\Users\\Maurice\\Desktop\\Logs

看到这个:

• http://docs.oracle.com/javase/6/docs /api/java/util/Properties.html

更精确地load方法:

• http://docs.oracle .com/javase/6/docs/api/java/util/Properties.html#load(java.io.Reader )

向下滚动一点，您将看到以下内容:

Scroll down a bit and you will see this among other things:

该方法不会在无效的转义字符之前将反斜杠字符\视为错误；反斜杠默默地掉了下来.例如，在Java字符串中，序列"\ z"将导致编译时错误.相比之下，此方法会静默删除反斜杠.因此，此方法将两个字符序列"\ b"等同于单个字符"b".

The method does not treat a backslash character, \, before a non-valid escape character as an error; the backslash is silently dropped. For example, in a Java string the sequence "\z" would cause a compile time error. In contrast, this method silently drops the backslash. Therefore, this method treats the two character sequence "\b" as equivalent to the single character 'b'.

反斜杠\是一个转义字符，否则将被静默删除.

Backslash \ is an escape character that is silently dropped otherwise.
