Java:可以在属性文件中换行吗？

Question

是否可以在 Java 属性文件的下一行继续一个长字符串？

例如，不知何故

myStr=Hello
      World

当我得到 getProperty("myStr") 时，它会返回“Hello World”？

Answer 1

行尾的反斜杠可让您跨越多行，并且忽略行首的空格:

myStr = Hello \
        World

注意:反斜杠必须在行尾；它必须是最后一个字符，后面不能有空格，等等。

Java docs这么说吧:

A logical line holds all the data of a key-element pair, which may be spread out across several adjacent natural lines by escaping the line terminator sequence with a backslash character \.

...

If a logical line is spread across several natural lines, the backslash escaping the line terminator sequence, the line terminator sequence, and any white space at the start of the following line have no affect on the key or element values.
