ResourceBundle file not found, properties file not in jar
提问by Jeankes
About the resourcebundle errors, I've read other questions about the same subject, but I didn't get any wiser. Tried different things, doesn't help. To give a little background: I developed a small app (JDK6), that does some flat file parsing and editing automatically. The app starts by reading some data from a properties file.
关于资源包错误，我已经阅读了关于同一主题的其他问题，但我没有更明智。尝试了不同的东西，没有帮助。提供一点背景知识：我开发了一个小应用程序 (JDK6)，它自动执行一些平面文件解析和编辑。该应用程序首先从属性文件中读取一些数据。
Important: I want to be able to change the properties file. I don't want to put it in the jar file.
重要提示：我希望能够更改属性文件。我不想把它放在 jar 文件中。
However, even with the little example app that I tried creating, based on another questions/answer [here][1]:
但是，即使使用我尝试创建的小示例应用程序，基于另一个问题/答案 [here][1]：
package restestapp;
import java.util.Locale;
import java.util.ResourceBundle;
public class ResourceBundleTester
{
public static void main(String[] args)
{
Locale locale = Locale.getDefault();
String basename ="myresource";
ResourceBundle resourceBundle = ResourceBundle.getBundle(basename, locale);
System.out.println(resourceBundle.getString("STARTING_MYAPP"));
}
}
Both files are here:
两个文件都在这里：
/home/dakoina/Documents/ResTestapp/ResTestApp.jar
/home/dakoina/Documents/ResTestapp/myresource.properties
or even
甚至
c:/temp/ResTestApp.jar
c:/temp/myresource.properties
But when I run it, it gives me this output:
但是当我运行它时，它给了我这个输出：
dakoina@ubuntu:~/Documents/ResTestapp$ java -cp /home/dakoina/Documents/ResTestapp/ -jar "ResTestApp.jar"

and in Windows, the same...
在 Windows 中，同样的......
c:\temp>java -jar ResTestApp.jar

I can't see where I am wrong :/
我看不出我错在哪里：/

-jarmeans: compose the classpath from the given jar and from all the ones it references in its manifest. So the -cpoption is ignored.
-jar意味着：从给定的 jar 和它在其清单中引用的所有 jar 组合类路径。因此该-cp选项被忽略。
Your command line should be:
你的命令行应该是：
java -cp /home/dakoina/Documents/ResTestapp;/home/dakoina/Documents/ResTestapp/ResTestApp.jar the.main.Class
That said, a resource bundle is used to load internationalized labels. If you just want to read properties, you'd bette use the java.util.Propertiesclass.
也就是说，资源包用于加载国际化标签。如果您只想读取属性，则最好使用java.util.Properties该类。

myresource.propertiesneeds to be in classpath for jar file
myresource.properties需要在 jar 文件的类路径中
put this properties file into jar and configure classpath (as described in the link)
将此属性文件放入 jar 并配置类路径（如链接中所述）
