我有一个弹簧启动应用程序,运行没有问题。我想编写一些单元测试并遇到以下异常:

我想要的只是测试@Service注释bean并正确连接它。

@RunWith(SpringRunner.class)
@SpringBootTest
public class ImageResizeTest {

    @Autowired
    private ImageService imageService;

    @Test
    public void imageResizeTest() throws IOException {
        BufferedImage image = ImageIO.read(new File("E:\\tmp\\original.jpg"));
        imageService.storeComicCover(image, "mytest.jpg");
    }
}

@Service
public class ImageService {
    private static final Logger LOG = LoggerFactory.getLogger(ImageService.class);
    public static final String FORMAT_NAME = "jpg";

    @Value("${image.norm.resize.height}")
    private int normalResizeHeight;
    @Value("${image.norm.resize.width}")
    private int normalResizeWidth;

    @Value("${image.thumb.resize.height}")
    private int thumbResizeHeight;
    @Value("${image.thumb.resize.width}")
    private int thumbResizeWidth;

    @Value("${image.mini.resize.height}")
    private int miniResizeHeight;
    @Value("${image.mini.resize.width}")
    private int miniResizeWidth;

    @Value("${image.comics.original.path}")
    private String originalComicPath;
    @Value("${image.stories.original.path}")
    private String originalStoriesPath;
    @Value("${image.characters.original.path}")
    private String originalCharactersPath;

    @Value("${image.comic.resized.path}")
    private String resizeComicPath;
    @Value("${image.stories.resized.path}")
    private String resizeStoriesPath;
    @Value("${image.characters.resized.path}")
    private String resizeCharactersPath;

    public ImageAttributes storeComicCover(BufferedImage originalImage, String originalImageName) {

我尝试在maven中添加缺少的lib和测试范围,但这没有效果。

我做错了什么?我感谢任何帮助。

答案 0 :(得分:0)

似乎缺少一些库。请将以下内容添加到您的pom.xml中并检查:

com.fasterxml.jackson.core jackson-databind 2.4.5
com.google.code.gson gson 2.3.1
net.minidev json-smart 2.1.1
org.slf4j slf4j-api 1.7.10
net.minidev asm 2.1.1

如果没有,问题出在其他地方。

答案 1 :(得分:0)

@SpringBootTest(classes = {... classesRequired ...})您可以尝试加载所需的类,看看它是否以这种方式工作。 SpringBootTest应该加载所需的应用程序上下文。
