如何从Java中的文件资源加载资源包？ [英] How to load a resource bundle from a file resource in Java?

问题描述

我在 c中有一个名为 mybundle.txt 的文件：/ temp -

I have a file called mybundle.txt in c:/temp -

c：/temp/mybundle.txt

如何加载此文件进入 java.util.ResourceBundle ？该文件是有效的资源包。

How do I load this file into a java.util.ResourceBundle? The file is a valid resource bundle.

这似乎不起作用：

java.net.URL resourceURL = null;

String path = "c:/temp/mybundle.txt";
java.io.File fl = new java.io.File(path);

try {
   resourceURL = fl.toURI().toURL();
} catch (MalformedURLException e) {             
}           

URLClassLoader urlLoader = new URLClassLoader(new java.net.URL[]{resourceURL});
java.util.ResourceBundle bundle = java.util.ResourceBundle.getBundle( path , 
                java.util.Locale.getDefault(), urlLoader );

推荐答案

只要您正确命名资源包文件（使用.properties扩展名），然后就可以了：

As long as you name your resource bundle files correctly (with a .properties extension), then this works:

File file = new File("C:\\temp");
URL[] urls = {file.toURI().toURL()};
ClassLoader loader = new URLClassLoader(urls);
ResourceBundle rb = ResourceBundle.getBundle("myResource", Locale.getDefault(), loader);

其中c：\ temp是持有该属性的外部文件夹（不在类路径上）文件，myResource与myResource.properties，myResource_fr_FR.properties等相关。

where "c:\temp" is the external folder (NOT on the classpath) holding the property files, and "myResource" relates to myResource.properties, myResource_fr_FR.properties, etc.
