【问题描述】：

我正在尝试掌握 Java 应用程序的内部化，如 here 所示。不过我不能。我创建了一个扩展ListResourceBundle 的类，如所述并尝试检索密钥。不过，我一直有一个例外。如果您查看教程，它会说使用 .class 文件。这不可能吧？

这是我使用的两个类，只是 MainWindow_xx_XX.java 文件之一，因为它们基本相同。首先是 ListResourceBundle：

public class MainWindow_en_US extends ListResourceBundle {

    @Override
    protected Object[][] getContents() {
        return contents;
    }
    private Object[][] contents = {
        {"fileLabel", "File"},
        {"newSessionLabel", "New session..."},
        {"openSessionLabel", "Open session..."},
        {"saveLabel", "Save"},
        {"exitLabel", "Exit"},
        {"editLabel", "Edit"},
        {"toolsLabel", "Tools"},
        {"helpLabel", "Help"}
    };
}

现在是我用来加载它的方法：

    private static final int DEFAULT_LOCALE = 0;
    private ResourceBundle bundle;
    public static Locale locale;
    public static final Locale[] supportedLocales = {
        new Locale("en", "US"),
        new Locale("es", "ES")
    };

public MainWindow() {
    for (Locale i : supportedLocales) {
        if (i.getLanguage().equals(Locale.getDefault().getLanguage())) {
            locale = i;
            break;
        } else {
            locale = supportedLocales[DEFAULT_LOCALE];
        }
    }
    bundle = ResourceBundle.getBundle("MainWindow", locale); //EXCEPTION POINTS HERE!!!
    initComponents();
}

我不断收到以下异常。我知道我可以通过属性文件来做到这一点，但是我无法让 Oracle 的极其简单的教程正常工作，这让我感到莫名其妙。

【解决方案1】：

您需要使用完全限定的基本名称：

bundle = ResourceBundle.getBundle("pkg.subpkg.resources.MainWindow", locale);

【讨论】：

这有助于我在msgfmt 命令中正确指定pkg.subpkg.resources.MainWindow。即命令是msgfmt --java2 -d source/folder/root/ -r pkg.subpkg.resources.MainWindow my/po/file.po

【解决方案2】：

您不能将文件命名为 MainWindow_es_ES。为了解决您的问题，请将您的文件重命名为 MainWindow es。

Locale locale = new Locale("es");
ResourceBundle rb = ResourceBundle.getBundle("yourPackageName.MainWindow", locale);   
System.out.print(rb.getObject("YourKey"));
