这是什么？他们是怎么来的？

I am writing a program use jsp and java, how can i use properties files to support multiple languages ? and by the way, there are always something like \u4345, What's this ? How do they come ?

推荐答案

对于多种语言，请查看 ResourceBundle 类。

For the multiple languages, check out the ResourceBundle class.

关于 \ u4345 ，这是Java的一个黑暗且非常烦人的传统角落。属性文件需要是ASCII格式，因此所有非ASCII字符都需要编码为 \uxxxx （它们的Unicode值）。您可以使用 native2ascii命令转换文件以使用此编码线工具。
如果您使用的是IDE或构建工具，则应该有一个选项可以自动调用它。

About the \u4345, this is one of the dark and very annoying legacy corners of Java. The property files need to be in ASCII, so that all non-ASCII characters need to encoded as \uxxxx (their Unicode value). You can convert a file to use this encoding with the native2ascii command line tool. If you are using an IDE or a build tool, there should be an option to invoke this automatically.

如果属性文件是您完全控制的对你自己，你可以从Java6开始也直接在属性文件中使用UTF-8（或任何其他字符集），并且在加载时指定编码：

If the property file is something you have full control over yourself, you can starting from Java6 also use UTF-8 (or any other character set) directly in the property file, and specify that encoding when you load it:

// new in Java6
props.load(new InputStreamReader(new FileInputStream(file), 'UTF-8'));

同样，这仅适用于您自己加载属性，而不是其他人这样做，例如一个ResourceBundle（用于国际化）。

Again, this only works if you load the Properties yourself, not if someone else does it, such as a ResourceBundle (used for internationalization).
