Java：准备资源（.png，.txt，.arff）以使用Eclipse创建可运行的Jar

Question

I have a java project in Eclipse and I have a couple of .arff files+1 png file.

I want to compile my project and create a runnable jar. The thing is I can't find the best solution so that the jar can run using arff files. Right now I have a structure like that:

Nameofproject
|
|
-------src
|        |
|        testpackage
|                      |
|                      |
|                      test1.java
|
 -------resources
|              |
|              | 
|              abc.arff
|              logo.png
|              ...

Inside my code I call the required arff files using inputReader=new BufferedReader(new FileReader( getClass().getResource("/resources/abc.arff").getFile() ));

and for the png file: logo= new ImageIcon(getClass().getResource("/resources/logo.png"));

Can you tell me what is the procedure to create a runnable jar which will be able to correctly read both arff and png files?

Answer 1

try

getClass().getClassLoader().getResource("resources/abc.arff");

Or if resources is marked as a source folder in your IDE, then

getClass().getClassLoader().getResource("abc.arff");

More info:

Check that you've designated resource as a source folder. When you build a jar, check where the resources are packaged within it. If they are in the root of the jar, it should be

getClass().getClassLoader().getResource("abc.arff");

otherwise, it will be something like:

getClass().getClassLoader().getResource("path/to/abc.arff");
