看看http://jersey.java.net/nonav/documentation/latest/user- guide.html#d4e323：
@GET
@Path("/images/{image}")
@Produces("image/*")
public Response getImage(@PathParam("image") String image) {
File f = new File(image);
if (!f.exists()) {
throw new WebApplicationException(404);
}
String mt = new MimetypesFileTypeMap().getContentType(f);
return Response.ok(f, mt).build();
}
