如何在属性文件中转义冒号 (:)? [英] How do you escape colon (:) in Properties file?

问题描述

我正在使用一个属性文件来存储我的应用程序的配置值.在其中一种情况下，我必须将值存储为xxx:yyy:zzz.当我这样做时，冒号用反斜杠转义 导致值在属性文件中显示为 xxx:yyy:zzz.

I am using a properties file to store my application's configuration values. In one of the instances, I have to store a value as xxx:yyy:zzz. When I do that, the colon is escaped with a back slash resulting in the value showing as xxx:yyy:zzz in the properties file.

我知道冒号 : 是 Properties Java 类的标准分隔符.但是我仍然需要保存没有反斜杠 的值.

I am aware that the colon : is a standard delimiter of the Properties Java class. However I still need to save the value without the back slash .

关于如何处理这个问题有什么建议吗?

Any suggestions on how to handle this?

推荐答案

将属性放入 Properties 对象并使用 store(...) 方法保存.该方法将执行任何所需的转义.Java 文档说:

Put the properties into the Properties object and save it using a store(...) method. The method will perform any escaping required. The Java documentation says:

"... 对于键，所有空格字符都以字符开头.对于元素，前导空格字符，但不包括嵌入或尾随空格字符，以字符开头.键和元素字符 #、!、= 和 : 用前面的反斜杠写入，以确保它们被正确加载."

如果您手动创建/编写文件，则只需手动转义字符.

You only need to manually escape characters if you are creating / writing the file by hand.

相反，如果您希望文件包含未转义的冒号字符，那您就不走运了.此类文件格式错误，可能无法使用 Properties.load(...) 方法正确加载.如果您沿着这条路线走下去，您将需要实现自己的自定义加载和/或存储方法.

Conversely, if you want the file to contain unescaped colon characters, you are out of luck. Such a file is malformed and probably won't load properly using the Properties.load(...) methods. If you go down this route, you'll need to implement your own custom load and/or store methods.
