我正在尝试加载资源文件夹中存在的文件,但出现异常。我正在使用java 9,具有读取文件代码的java文件存在于其他模块中,调用代码位于其他模块中。有人可以建议如何在这里进行吗?

代码是: -
public class Main {
public static void main(String[] args) {
ServiceLoader<IReader> serviceLoader = ServiceLoader.load(IReader.class);
try {
System.out.println(serviceLoader.iterator().next().read("genome-tags.csv", Main.class).size());
} catch (IOException e) {
e.printStackTrace();
}
}
}
public interface IReader {
List<String> read(String fileLocation, Class clazz) throws IOException;
default File getFile(String fileLocation, Class clazz) {
URL url = clazz.getResource(fileLocation);
return new File(getClass().getClassLoader().getResource(fileLocation).getFile());
}
}
public class FileSystemReader implements IReader{
@Override
public List<String> read(String fileLocation, Class clazz) throws IOException {
return Files.readAllLines(Paths.get(getFile(fileLocation, clazz).getName()));
}
}
谢谢,
