        } catch (Exception ignored) {
            throw new InitializationException( InitializationErrorCodes.IMAGE_TEST_ERROR );
        }
    }
}

为什么一切正常，但是在执行java -jar时却不能正常工作？我不知道要尝试什么，因为当我按play或debug时，在intellij中也可以正常工作。

我知道它失败的行如下：

文件=新的ClassPathResource（“ /TestResources/DogImageForTest.jpg”）.getFile（）;

我在jar文件中进行了检查，并且图像在其中：

image

提前感谢

我找到了解决方案。在一个罐子里，我不能使用.getFile（）;因为它期望在系统中包含一个文件。我使用的Intead：

fileStream = new ClassPathResource( "/TestResources/DogImageForTest.jpg" ).getInputStream();
            return new MockMultipartFile( "DogImageForTest.jpg", "DogImageForTest.jpg", "image/jpeg",fileStream );

通过流可以完美工作
