java getResource() 不工作

Question

this is driving me crazy. I have a NetBeans project in a folder with the following structure:

MyProject
---- build
---- src
---- resources

in src my code is in packages. What I am trying to do is to use

getClass().getResource("/resources/new.png"); 

from a class in package com.my.package but it just refuses to work. The "new.png" image is in the resources folder? Am I missing something here?

After a lot of playing around and moving the "new.png" image here and there to see when it will find the image, it finally worked but only when I put the image in the build folder. So what do I have to do to make this work?

edit: sorry, wrong String in method parameter. Corrected now

Answer 1

I'm not familiar with NetBeans, but the problem is probably that the resources folder (or the root of the project, for that matter) is not on the classpath, unlike build .

You need to configure NetBeans to add the root folder, or resources to the classpath, and load the file relative to there.

Answer 2

这很好用：

BufferedImage image = ImageIO.read(getClass().getClassLoader().getResourceAsStream("file_name"));

Answer 3

look out with ImageIO.read(getClass().getClassLoader().getResourceAsStream("file_name"));

...on windows you will get a URL encoded string, with %20 for spaces, so if you want to use that path to load a file, first call pathString.replace("%20", " ")...that $hice just nailed me in live!
