在 Spring 引导应用程序中从 JAR 上的资源文件夹中获取图像

Question

I have a spring boot application. When I deploy mi application in a local Tomcat as a war, I'm able to use images from the resources folder by this way:

ResourceUtils.getFile("classpath:Logo.png")

My problem is when I package the applications as a JAR. Seems that is not able to find the images... After some time searching the inte.net, I tried a few different things, but none have worked so far.

Resource resource  = new ClassPathResource("classpath:Logo.png");
InputStream inputStream = resource.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
imagePart.attachFile(FileCopyUtils.copyToString(reader));

Edit: Project Structure

Answer 1

Could you please share the project structure? If the images are placed in test/resources/ or main/resources folder then the jar will not have any resources from tests or main folder. That could be one possibility.
