我在嵌入式Jetty服务器上安装了一个restlet应用程序。 一个ServerResource通过represent（）方法实现HTTP Get请求。 我们希望URL形成如下：server：port / model？id = 345
@Get
public Representation represent() {
String id = getQuery().getFirstValue("id");
Representation result = null;
Model model = daoFactory.getModelDao().findById(id);
File modelFile = model.getFile();
FileRepresentation fr = new FileRepresentation(modelFile, MediaType.APPLICATION_OCTET_STREAM, -1);
result = new InputRepresentation(fr.getStream(), fr.getMediaType());
setStatus(Status.SUCCESS_ACCEPTED);
return result;
}
当执行请求时（我尝试使用文本和二进制文件），http连接由服务器关闭，显示以下跟踪

使用文本文件（json）和MediaType.APPLICATION_JSON实现相同的代码确实有效，但仅适用于小文件（大约100KB以下）
