如何解决“已达到 http.client.requests 的最大 URI 标记数”警告？

我在我的应用上收到此警告。我正在同时阅读大约30个读者的RFIDTAG。每次有标签进来时，我都会点击数据库，看看它是否在那里。我有一个我正在使用的休息 API。所以我使用 rest 模板来命中 rest api。关于如何解决这个问题的任何想法？谢谢！

这是我的一些代码：

private void vehicleRequests(List<Maybevehicle> vehicles){
    //process list of unique tags to see if they are in the database and linked to a vehicle
    List<Maybevehicle> foundMaybeVehs= new ArrayList<>();
    List<Maybevehicle> notFound=new ArrayList<>();
     if(!vehicles.isEmpty()){
             for (Maybevehicle v: vehicles){
                Future<Maybevehicle> r=aService.batchVehTags(v);

                try{
                    Maybevehicle m=r.get(2000, TimeUnit.SECONDS);
                    if(r.isDone()){
                        if (!(m.getB().getVin().equals("notindb"))){
                            foundMaybeVehs.add(m);
                        }
                        }
                    }
                }catch(InterruptedException | ExecutionException | TimeoutException e){

                }
             }

              if(!foundMaybeVehs.isEmpty()){
                 addLocation(foundMaybeVehs);
             }
     }else{
         log.info("no vehicles to check.");
     }

}       


@Override
public Future<Maybevehicle> batchVehTags(Maybevehicle v) {
    Future<Maybevehicle> future=null;
         try{
                 SimpleTaskMaybeveh task=new SimpleTaskMaybeveh(v, appRestTemplate);
                  future=dbService.submit(task);

             }catch(Exception e){
                    e.printStackTrace();
                 }

            return future;
        }




}

public class SimpleTaskMaybeveh implements Callable<Maybevehicle>{

private RestTemplate appRestTemplate;
private Maybevehicle veh;

public SimpleTaskMaybeveh(Maybevehicle veh, RestTemplate appRestTemplate){
    this.veh=veh;
    this.appRestTemplate=appRestTemplate;
}

@Override
public Maybevehicle call(){
  String url="http://url/"+veh.getB().getRfidtag();
    String authString= "";
    byte[] encodedAuth= Base64.encodeBase64(authString.getBytes(Charset.forName("US-ASCII")));
    String authHeader="Basic "+new String(encodedAuth);
    HttpHeaders headers = new HttpHeaders();
    headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
    headers.set("Authorization", authHeader);
    HttpEntity<Bmwvehiclemain> requestEntity=new HttpEntity <Bmwvehiclemain>(headers);
    ResponseEntity<Bmwvehiclemain> results=appRestTemplate.exchange(url, HttpMethod.GET, requestEntity, Bmwvehiclemain.class);
    try{
        Bmwvehiclemain n=results.getBody();
        Maybevehicle d=new Maybevehicle(n,veh.getNewtaglocation());
        return d;
    }catch(Exception e){
        Maybevehicle notveh=new Maybevehicle("notindb");
        return notveh;
    }
}
