如何在Scala中使用相对路径读取文本文件 [英] How to read a text file using Relative path in scala

问题描述

我有一个用scala编写的简单的mvn项目.我想访问一个文本文件并阅读其内容.代码工作正常，但是唯一的问题是读取文本文件时我给出了绝对路径.以下是我的项目的目录结构.

I have a simple mvn project written in scala. I want to access a text file and read its content. The code is working fine but the only issue is I am giving the absolute path when reading the text file. Following is the directory structure of my project.

如何使用相对路径读取该文件? (我是否必须将movies.txt文件移动到资源目录中，如果还是这样，我将如何读取该文件?)

How can I use the relative path to read that file? (Do I have to move the movies.txt file in to the resources directory, if so still how would I read that file?)

任何见识将不胜感激.谢谢

Any insight will be much appreciated. Thank you

在模拟"是包对象的myobject.scala中，我使用绝对路径访问movie.txt文件.

In the myobject.scala where the Simulate is the package object, I access the movies.txt file using the absolute path.

import scala.io.Source
Source
    .fromFile("/home/eshan/projecs/myproject/movies.txt")
    .getLines
    .foreach { line =>
    count+=1
      // custom code            
}

推荐答案

将movies.txt移至resources目录，然后可以执行以下操作:

Move your movies.txt to resources dir, then you can do the following:

val f = new File(getClass.getClassLoader.getResource("movies.txt").getPath)

import scala.io.Source
Source
    .fromFile(f)
    .getLines
    .foreach { line =>
    count+=1
      // custom code            
}
