如何读取文本文件的相对路径 [英] how to read text file relative path

问题描述

我在这里阅读了一些资料。那里，但没有得到以下代码工作。基本上，我希望从文件夹'src'中读取一个名为'Administrator'的文本文件。我需要一个相对路径，因为这个项目可能会转移给另一个人。请耐心等待。

I have read sources here & there, but did not get the following code working. Basically, I wish to read a text file, named 'Administrator' from the folder 'src'. I will need a relative path, since this project may be transferred to another person. Please be patient with me.

public void staffExists () throws IOException
    {               
        //http://stackoverflow.com/questions/2788080/reading-a-text-file-in-java
        BufferedReader reader = new BufferedReader(new FileReader(getClass().getResourceAsStream ("/DBTextFiles/Administrator.txt")));

        try
        {               
            String line = null;
            while ((line = reader.readLine()) != null)
            {
                if (!(line.startsWith("*")))
                {
                    System.out.println(line);
                }
            }

        }
        catch (IOException ex)
        {
            ex.printStackTrace();
        }               

        finally
        {
            reader.close();
        }           
    }

推荐答案

这是一个有效的绝对路径（在我所知的系统上）：

This is a valid absolute path (on the systems I'm aware of):

    /path/to/directory/../../otherfolder/etc/

那么其他答案说，是通过以下方式获取当前目录的路径： / p>

So what the other answer was saying, was to get the path to the current directory with:

    String filePath = new File("").getAbsolutePath();

然后将您的相对路径连接到：

Then concatenate your relative path with:

    filePath.concat("path to the property file");
