json - Jersey - Maven - MessageBodyWriter 未找到媒体类型=应用程序/json

Question

目前我遇到的问题是 Netbeans 中的所有内容都可以正常工作，但是如果我使用命令“java -jar FILENAME PARAMETERS”启动 jar 文件，则会出现以下错误。

找不到 Media type=application/json 的 MessageBodyWriter，输入
=class java.util.ArrayList, genericType=java.util.List

我需要专家来解决这个问题:/。这很奇怪，因为当我在 Netbeans 中执行 jar 时它可以工作。

功能:

@GET
@Path("/getimages")
@Produces(MediaType.APPLICATION_JSON)
public List<Image> getImages() {
    availableImages = getImageListFromDirectory(Paths.get(configuration.getProperties().get(BASE_DIR).toString()));
    return availableImages;
}

谢谢指教!

此致

jersey-media-json-jackson has to be the first dependency.
