我正在尝试从从属性读取的文件路径中读取文件,但我不断收到 FileNotFoundException (文件存在)。

测试属性:

test.value = "src/main/resources/File.csv"

加载属性.java:

public class LoadProperties {

   public static void main(String[] args) throws FileNotFoundException, IOException {

      Properties aProp = new Properties();
      aProp.load(new FileInputStream("src/main/resources/test.properties")); // works

      String filepath = aProp.getProperty("test.value");
      System.out.println(filepath); // outputs: "src/main/resources/File.csv"

      FileReader aReader = new FileReader("src/main/resources/File.csv"); // works
      FileReader aReader2 = new FileReader(filepath); // java.io.FileNotFoundException
   }
}

为什么在它上面的行正常工作时抛出这个异常?我应该如何从提供属性的路径中读取文件?

您不应该将 " 放入您的属性文件中。Java 将其视为:

String file = "\"src/main/resources/File.csv\"";

test.value =src/main/resources/File.csv

您不需要在属性文件中使用双引号来表示连续字符串。

您可以编写自己的逻辑来读取属性文件,文件路径中是否存在单引号或双引号无关紧要

String propertyFileLocation = "C:\a\b\c\abc.properties";
try
    {
        fileInputStream = new FileInputStream(propertyFileLocation);
        bufferedReader = new BufferedReader(new InputStreamReader(fileInputStream));
        properties = new Properties();
        String currentLine = null;
        String[] keyValueArray = null;
        while ((currentLine = bufferedReader.readLine()) != null) {
            if (!currentLine.trim().startsWith("#")) {
                keyValueArray = currentLine.split("=");
                if (keyValueArray.length > 1) {
                    properties.put(keyValueArray[0].trim(), keyValueArray[1].trim().replace("\\\\","\\"));
                }
            }
        }
    } 
    catch (Exception e)
    {
        return null;
    }
