创建名称为＆＃39; entityManagerFactory＆＃39;的bean时出错：如果没有指定LoadTimeWeaver，则无法应用类转换器

我目前正在开展一个小型学校项目，在那里我需要建立一个图像列表，您可以在其中预先形成crud功能。我目前正在maven项目中使用JAX-RS处理REST API。我必须使用JPA与数据库通信。我使用entityManager来获取数据。

@Stateless
@Path("/image")
public class ImageController {

    EntityManager entityManager;

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Response getAllImages() {
        try {
            List<Image> listOfImages;

            listOfImages =  entityManager.createNamedQuery("Image.findAll", Image.class).getResultList();
            GenericEntity<List<Image>> imageWrapper = new GenericEntity<List<Image>>(listOfImages) {
            };

            return Response.ok(imageWrapper).build();
        } catch (Exception e) {
            System.out.println(e);
            return Response.noContent().build();
        }
    }
}

但是当我要调试我的glassfish控制台时说：

现在我对这意味着什么并不使用springframework感到有点困惑。如果不是nessecary我宁愿保持这种方式现在。我将发布我目前拥有的所有.xml文件。

如果我的信息不充分，只需要求更多信息，我会尽力为您提供所需信息。我对此的了解非常有限，所以希望我的问题不是愚蠢的。非常感谢提前！
