如何从资源文件夹加载文件？ [英] How do I load a file from resource folder?

问题描述

  / src / main / java / 
 / src / main / resources / 
 / src / test / java / 
 / src / test / resources / 
  

我在 /src/test/resources/test.csv 中有一个文件，我想从 / src中的单元测试加载文件/test/java/MyTest.java

我的代码没有起作用。它抱怨没有这样的文件或目录。

  BufferedReader br = new BufferedReader（new FileReader（test.csv））
  

我也尝试过这个

 code> InputStream is =（InputStream）MyTest.class.getResourcesAsStream（test.csv））
  

这也不行。它返回 null 。我正在使用Maven构建我的项目。

提前感谢

解决方案

尝试下一个：

  ClassLoader classloader = Thread.currentThread（）。getContextClassLoader（）; 
 InputStream is = classloader.getResourceAsStream（test.csv）; 
  

---

如果上述不起作用，各种项目已添加以下类： ClassLoaderUtil （代码这里）。

My project has following structure.

/src/main/java/
/src/main/resources/
/src/test/java/
/src/test/resources/

I have a file in /src/test/resources/test.csv and I want to load the file from a unit test in /src/test/java/MyTest.java

I have this code which didn't work. It complains "No such file or directory".

BufferedReader br = new BufferedReader (new FileReader(test.csv))

I also tried this

InputStream is = (InputStream) MyTest.class.getResourcesAsStream(test.csv))

This also doesn't work. It returns null. I am using Maven to build my project.

Thanks in advance.

解决方案

Try the next:

ClassLoader classloader = Thread.currentThread().getContextClassLoader();
InputStream is = classloader.getResourceAsStream("test.csv");

---

If the above doesn't work, various projects have been added the following class: ClassLoaderUtil (code here).
