Java:如何在src/main/resources中打开测试中的文本文件?

my project struture looks like

我的项目结构看起来像

project/
       src/main/
               java/ ...
               resources/
                         definitions.txt
               test/
                    CurrentTest.java
               resources/ ...

In my test I need to open the definitions.txt

在我的测试中，我需要打开definition .txt

I do

我做

 @Test
 public void testReadDesiredDefinitions() throws PersistenceException, IOException {
        final Properties definitions = new Properties();
        definitions.load(new ResourceService("/").getStream("desiredDefinitions"));
        System.out.println(definitions);
 }

When I run this, I get

当我运行这个，我得到

java.lang.NullPointerException
    at java.util.Properties$LineReader.readLine(Properties.java:418)
    at java.util.Properties.load0(Properties.java:337)
    at java.util.Properties.load(Properties.java:325)

How can I read this text file?

如何读取这个文本文件?

The "current directory" of unit tests is usually the project directory, so use this:

单元测试的“当前目录”通常是项目目录，所以使用以下方法:

File file = new File("src/main/resources/definitions.txt");

and load the properties from the file:

并从文件中加载属性:

definitions.load(new FileInputStream(file));

If this doesn't work, or you want to check what the current directory is, just print out the path and it will be obvious what the current directory is:

如果这不起作用，或者您想要检查当前目录是什么，只要打印出路径，那么很明显当前目录是什么:

System.out.println(file.getAbsolutePath());

#2

You can make use of Class#getResourceAsStream to easily create a stream to a resource file.

您可以使用Class# getresourcestream来轻松地为资源文件创建一个流。

definitions.load(getClass().getResourceAsStream("/main/java/resources/definitions.txt"));

The location parameter should be the relative file path with regards to your project base (my guess was main).

位置参数应该是与项目基础相关的文件路径(我的猜测是主要的)。

#3

If your resources directory is a source folder, you can use /resources/definitions.txt as a correct path.

如果资源目录是源文件夹，可以使用/resources/定义。txt是正确的路径。

I don't know about ResourceService but this should work:

我不知道ResourceService，但是这个应该可以:

final Properties definitions = new Properties();
definitions.load(getClass().getResourceAsStream("/resources/definitions.txt"))

#4

File file = new File("../src/main/resources/definitions.txt");

文件文件=新文件(".. ./src/main/resources/definitions.txt");
