Eclipse getResourceAsStream返回null [英] Eclipse getResourceAsStream returning null

问题描述

我无法获取getResourceAsStream来查找文件。我把文件放在顶级目录，目标目录等中，并且在前面也尝试过一个/。每次返回null。

I cannot get getResourceAsStream to find a file. I have put the file in the top level dir, target dir, etc, etc and have tried it with a "/" in front as well. Everytime it returns null.

任何建议？谢谢。

public class T {
 public static final void main(String[] args) {

  InputStream propertiesIS = T.class.getClassLoader().getResourceAsStream("test.txt");

  System.out.println("Break");
 }
}

推荐答案

您的文件test.txt到同一个目录，你的类的java文件是（相同的包）。然后使用

Put your file "test.txt" into the same directory where the java file of your class is (same package). Then use

T.class.getResourceAsStream( "test.txt" );

这样做是因为eclipse自动将文件作为资源复制到类路径中。使用命令行时，您必须手动执行此操作。

This works, because eclipse automatically copies the file as a resource to the classpath. When using the command line, you have to do this by hand.
