Question

URL propFile = this.getClass().getResource("/sample.xml");

我正在使用上述方法加载属性文件。并尝试在Web应用程序项目中对其进行操作。我的sample.xml存在于我的war文件src.main.resources文件夹中。

public void saveProperties(Properties prop) {
    log.info("URL is ::::::::::::::::::::" + propFile);
    FileSystem fs = FileSystems.getDefault();
    Path workflowPath = fs.getPath(propFile.getPath());
    try {
        OutputStream os = Files.newOutputStream(workflowPath);
        prop.storeToXML(os, "modified the path");
    } catch (IOException e) {
        e.printStackTrace();
    }
}

public Properties getAllProperties() {
    Properties pro = new Properties();
    try {
        pro.loadFromXML(propFile.openStream());
    } catch (IOException e) {
        e.printStackTrace();
    }
    return pro;
}

我有两种方法。不确定为什么saveProperties抛出FileNotFoundException和getAllProperties正在加载同一文件中的所有属性。

this.getClass（）。getResource（）不能统一工作
