java.util.MissingResourceException：找不到基本名称'property_file name'的包，locale en_US [英] java.util.MissingResourceException: Can't find bundle for base name 'property_file name', locale en_US

问题描述

我正在尝试创建一个实用程序类 ReadPropertyUtil.java ，用于从属性文件中读取数据。虽然我的类位于util目录下，但我的 skyscrapper.properties 文件放在其他目录中。

I am trying to create a utility class ReadPropertyUtil.java for reading data from property file. While my class is located under a util directory , my skyscrapper.properties file is placed in some other directory.

但是，当我尝试使用 [ResourceBundle] [1] 访问属性时，我得到异常，无法加载该包。

But , when i try to access the properties using [ResourceBundle][1], i get exceptions, that bundle can't be loaded.

下面是关于我如何阅读属性的代码以及显示我的目录结构的图像。

Below is the code on how I am reading the properties and also an image which shows my directory structure.

ReadPropertiesUtil.java

/**
 * Properties file name.
 */
private static final String FILENAME = "skyscrapper";

/**
 * Resource bundle.
 */
private static ResourceBundle resourceBundle = ResourceBundle.getBundle(FILENAME);

/**
 * Method to read the property value.
 * 
 * @param key
 * @return
 */
public static String getProperty(final String key) {
    String str = null;
    if (resourceBundle != null) {
        str = resourceBundle.getString(key);
            LOGGER.debug("Value found: " + str + " for key: " + key);
    } else {
            LOGGER.debug("Properties file was not loaded correctly!!");
    }
    return str;
}

目录结构

此行提供错误私有静态ResourceBundle resourceBundle = ResourceBundle.getBundle（FILENAME）;

I我无法理解为什么这不起作用，解决方案是什么。 src 文件夹已完全添加到构建路径中。

I am unable to understand why isn't this working and what is the solution. The src folder is already added in build path completely.

推荐答案

尝试使用资源的完全限定名称：

Try with the fully qualified name for the resource:

private static final String FILENAME = "resources/skyscrapper";
