Java ResourceBundle leading whitespace in values
提问by prongs
I'm trying out the example given at Oracle's documentations. The java file is hereas shown in that page. Now with this java file, I keep a LabelsBundle.propertiesfile in the same directory.
我正在尝试Oracle 文档中给出的示例。java文件在这里，如该页面所示。现在有了这个 java 文件，我LabelsBundle.properties在同一个目录中保存了一个文件。
# This is the default LabelsBundle.properties file
s1 = computer
s2 = disk
s3 = monitor
s4 = keyboard
it seems that the trailing whitespace is not ignored while reading the values and the leading whitespaces are ignored.
似乎在读取值时不会忽略尾随空格，并且会忽略前导空格。
So if I want leading spaces to be there, what do I do?
所以如果我想要引导空间在那里，我该怎么做？
In other words, what do I need to do to read the value of s1as
换句话说，我需要做什么才能读取s1as的值
computer
instead of
代替
computer
?

A Unicode escape sequence \u0020should do it, because the properties parser should recognise it as an actual value and the Java String should interpret \u0020as the Unicode code point for space.
Unicode 转义序列\u0020应该这样做，因为属性解析器应将其识别为实际值，而 Java 字符串应解释\u0020为空格的 Unicode 代码点。
Alternatively, IIRC, you can escape the space with a backslash like this \ my value. Works for keys, too.
或者，IIRC，您可以使用这样的反斜杠来转义空格\ my value。也适用于钥匙。

You can escape space with backlash:
您可以通过反冲来逃避空间：
s1 =\ computer
