我有一个 Web 服务 REST:
@Path("/Vehicles")    
public class Vehicles{
        @GET
        @Path("/Cars")
        @Produces(aplicattion/json)
        public String Cars() {
            Car[] cars = Consulting my database...
            Gson gson = new Gson();
            return gson.toJson(cars); 
        }
我使用网络服务:
  try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpGet get = new HttpGet(
                    "http://localhost:8080/Concessionaire/rest/Vehicles/Cars");
            HttpResponse resp = httpClient.execute(get);
            String respGET = EntityUtils.toString(resp.getEntity());
            Gson gson = new Gson();
            Cars[] c = gson.fromJson(respGET,Cars[].class);
   }catch(Exception e){
   }
但是出现了这个异常: Expected BEGIN_ARRAY but was String at line 1 colum 6 有什么问题?
