Java rest api服务 spring 启动中出现IllegalFormatConversionException

我正在try 为我的服务编写测试，其中一些测试没有通过描述抛出意外的异常类型，Expect:&lt；com.bestteam.urlshorter.exception.ItemNotFoundException&gt；但Was:&lt；java.util.IllegalFormatConversionException&gt；

    @Test
    public void testGetWhenLinkNotFoundThenThrowException() {
        assertThrows(ItemNotFoundException.class, () -> {
            linkService.get("shortLink");
        });
        verify(linkRepository, times(0)).save(link);
    }

下面是这个GET方法

  public LinkDto get(String shortLink) {
    Link linkEntity = linkRepository.findById(shortLink).orElseThrow(() -> new ItemNotFoundException(Link.class, shortLink));
    linkEntity.setOpenCount(
      linkEntity.getOpenCount() + 1
    );

    linkRepository.save(linkEntity);
    return linkMapper.toDto(linkEntity);
  }

LinkMapper是一个自定义映射器

  public LinkDto toDto(Link link) {
    if (link == null) {
      return null;
    }

    LinkDto linkDto = new LinkDto();
    linkDto.setLink(link.getLink());
    linkDto.setShortLink(link.getShortLink());
    linkDto.setOpenCount(link.getOpenCount());
    linkDto.setIsActive(link.getIsActive());
    linkDto.setCreationDateTime(link.getCreationDateTime());
    linkDto.setExpirationDateTime(link.getExpirationDateTime());

    if (link.getUser() != null) {
      linkDto.setUserId(link.getUser().getId());
    }

    return linkDto;
  }

ItemNotFoundException异常

    @ResponseStatus(value = HttpStatus.NOT_FOUND)
public class ItemNotFoundException extends RuntimeException {
  public static final String DEFAULT_MESSAGE = "Entity not found";

  public ItemNotFoundException() {
    super(DEFAULT_MESSAGE);
  }

  public ItemNotFoundException(String message) {
    super(message);
  }

  public ItemNotFoundException(Class<?> entityClass, Long id) {
    super(String.format("%s: {%s, id=%d}", DEFAULT_MESSAGE, entityClass.getSimpleName(), id));
  }

  public ItemNotFoundException(Class<?> entityClass, String id) {
    super(String.format("%s: {%s, id=%d}", DEFAULT_MESSAGE, entityClass.getSimpleName(), id));
  }
}

我try 使用AdviceController创建全局异常处理程序，但没有帮助
