getResourceAsStream()返回null [英] getResourceAsStream() returns null

问题描述

我有以下问题

InputStream input = FileHandle.class.getResourceAsStream("/data/sounds/back.ogg");

返回null，但是

InputStream input = FileHandle.class.getResourceAsStream("/data/sounds/back.png");

返回InputStream，这两个文件也都在此文件夹中.有什么问题吗?

returns InputStream, also both files are in this folder. What can be wrong?

推荐答案

如果路径以"/"开头，则Java会在文件系统的根目录中搜索文件.

If your path starts with "/", java will search your file in the root of your file system.

如果它在您的根文件夹中，请首先检查文件是否存在:

If it is in your root folder, first of all, check if file exists:

ls -l /data/sounds/ | grep "back.ogg"

如果它不存在或您没有权限，那么您就有了答案.

If it does not exists or you do not have permissions, then you have the answer.

如果存在，则可以尝试另一种方法来获取其InputStream:

If it exists, you could try another way to get its InputStream:

InputStream is = new FileInputStream("/data/sounds/back.ogg");
