找不到资源包异常 [英] Can't find resource bundle exception

问题描述

我想使用名为 strings 的资源包，但在 MainApplication.java 中运行我的 main 方法时出现以下错误:

I want to use a resource bundle called strings but I get following error when running my main method in MainApplication.java:

java.util.MissingResourceException: Can't find bundle for base name strings, locale de_DE
    at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:1564)
    at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:1387)
    at java.util.ResourceBundle.getBundle(ResourceBundle.java:845)
    at logic.MainApplication.start(MainApplication.java:20) (...)

我的项目结构:

strings.properties 和 strings_de_DE.properties 两个文件与 MainApplication.java 存放在同一个目录下，三个文件都在目录 pi_display/src/logic/(IntelliJ 将它们放入一个虚拟的Resource Bundle"目录中，以便更清晰地显示项目结构).

The two files strings.properties and strings_de_DE.properties are stored in the same directory as MainApplication.java and all three files are in the directory pi_display/src/logic/ (IntelliJ puts them into a virtual "Resource Bundle" directory for a clearer display of the project structure).

主类/方法:

public class MainApplication {
    public static void main(String[] args) {
        Locale locale = Locale.GERMANY;
        ResourceBundle resources = ResourceBundle.getBundle("strings", locale);
        // ...
    }

我已经尝试将文件移动到其他包并指定包的 baseName(即 logic.strings 或其他包结构，如果我将它们移动到其他地方).

I've already tried to move the files to other packages and specify the baseName of the bundle (i.e. logic.strings or other package structures if I moved them elsewhere).

我不明白为什么在给定 MainApplication 的情况下找不到包，并且包文件在同一目录中.

I don't understand why the bundle can't be found given MainApplication and the bundle files are in the same directory.

推荐答案

您可能为您的包使用了错误的 baseName.根据 文档:

You probably using wrong baseName for your bundle. According to documentation:

使用指定的基本名称获取资源包，默认语言环境和调用者的类加载器

Gets a resource bundle using the specified base name, the default locale, and the caller's class loader

类加载器"意味着从带有编译类的文件夹加载的资源.在屏幕截图中，资源的路径是 src/logic/strings.properties，所以它应该位于 classes/logic/ 文件夹中，并且作为 baseName 你应该使用logic/strings(或logic/strings.properties，我不确定).

"Class loader" means that resource loaded from folder with compiled classes. In the screenshot, the path to your resource is src/logic/strings.properties, so it should be located in classes/logic/ folder, and as baseName you should use logic/strings (or logic/strings.properties, I'm not sure about that).
