我正在尝试使用 Commons-configuration api 为我的 maven Web 项目读取放置在 src/main/resources 文件夹中的 config.properties 文件。对于普通的 maven 项目，我可以毫无问题地使用它，但在 web 项目中，这不知何故不起作用。这是我的 pom.xml

我正在使用下面的代码阅读这个文件

static {

    Configuration config = null;
    try {

        //config = new PropertiesConfiguration("resources/config.properties"); this package is placed in src/main/java and using this it works perfectly fine
        config = new PropertiesConfiguration("src/main/resources/config.properties"); // this doesn't seem to work

    } catch (ConfigurationException e) {
        e.printStackTrace();
    }

    UPLOAD_LOCATION = config.getString("image.upload.location");
    TABLE_NAME = config.getString("table.name");}

我是否错过了 pom.xml 中的任何内容。请帮忙！

当您创建 PropertiesConfiguration 对象的实例时，它将在当前类路径中搜索您指定的文件。对于 Maven Web 项目，该src/main/resources文件夹应该已经包含在类路径中，因此不需要在您的文件名前面加上目录。换句话说，这应该有效：

config = new PropertiesConfiguration("config.properties");
