Eclipse没有看到java文件属性



我正在用Java进行国际化。

我已经创建了两个文件:MessageBundle_en_US.propertiesMessageBundle_en_IN.properties

MessageBundle_en_US.properties

greeting=Hello, how are you?

MessageBundle_en_IN.properties

greeting=Halo, apa

最后,这里是主要的类:

import java.util.*;
public class InternationalizationDemo {
public static void main(String[] args) {
ResourceBundle bundle =
ResourceBundle.getBundle("MessageBundle", Locale.US);

System.out.println(
"Message in "
+ Locale.US
+ ": "
+ bundle.getString("greeting")
);

//changing the default locale to indonasian
Locale.setDefault(new Locale("in", "ID"));
bundle = ResourceBundle.getBundle("MessageBundle");

System.out.println(
"Message in "
+ Locale.getDefault()
+ ": "
+ bundle.getString("greeting")
);
}
}

我收到以下错误堆栈:

Exception in thread "main" java.util.MissingResourceException: Can't find bundle for base name MessageBundle, locale en_US
at java.base/java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:2055)
at java.base/java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:1689)

at java.base/java.util.ResourceBundle.getBundle(ResourceBundle.java:932)
at provame.InternationalizationDemo.main(InternationalizationDemo.java:8)

UPDATE我已经找到了它无法看到文件的原因,首先你需要把*properties文件放在与主类相同的目录中,就像人们在评论中建议的那样,你应该这样调整对文件的调用:

projectName/propertiesFileName

这就是全部。

  1. *.properties文件与InternationalizationDemo.java放在同一文件夹中
  2. 将:MessageBundle_en_IN.properties重命名为:MessageBundle_in_ID.properties
