Eclipse getResourceAsStream 返回 null [英] Eclipse getResourceAsStream returning null

问题描述

我无法使用 getResourceAsStream 来查找文件.我已将文件放在顶级目录、目标目录等中，并尝试在前面加上/".每次都返回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.

有什么建议吗?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

把你的文件test.txt"放到你的类的java文件所在的同一个目录下(同一个包).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" );

这是可行的，因为 eclipse 会自动将文件作为资源复制到类路径.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.
