异步接口类

public interface Algorithm {


   /**
    * 异步调用,传入整个url
    * @param url 算法名
    * @param jsonParam json字符串
    * @param onSuccess
    * @param onError
    * @return
    */
   @Post(
         url = "{url}",
         async = true
   )
    Future<JSONObject> asyncAlgorithmUrl(@Var("url") String url, @JSONBody String jsonParam, OnSuccess<JSONObject> onSuccess, OnError onError);

   @Post(
         url = "{url}",
         async = true
   )
   Future<String> asyncAlgorithmUrlString(@Var("url") String url, @JSONBody String jsonParam, OnSuccess<String> onSuccess, OnError onError);

   /**
    * 异步调用预测算法接口,传入整个url
    * @param url 算法名
    * @param jsonParam json字符串
    * @param onSuccess
    * @param onError
    * @return
    */

   @Post(
         url = "{url}",
         async = true
   )
    Future<JSONObject> asyncPreAlgorithmUrl(@Var("url") String url, @JSONBody String jsonParam, OnSuccess<JSONObject> onSuccess, OnError onError);


   /**
    * 异步调用传入算法名称即可
    * @param api
    * @param jsonParam
    * @param onSuccess
    * @param onError
    * @return
    */
   @Post(
         url = "{api}",
         async = true
   )
    Future<String> asyncAlgorithmApi(@Var("api") String api, @JSONBody String jsonParam, OnSuccess<String> onSuccess, OnError onError);

   /**
    * 异步调用传入算法url+算法名
    * @param url 主机加端口
    * @param api
    * @param jsonParam
    * @param onSuccess
    * @param onError
    * @return
    */
   @Post(
         url = "http://{url}/{api}/",
         async = true
   )
    Future<String> asyncAlgorithmApi(@Var("url") String url, @Var("api") String api, @JSONBody String jsonParam, OnSuccess<String> onSuccess, OnError onError);


   /**
    * 异步调用传入算法url+算法名
    * @param url 主机加端口
    * @param api
    * @param jsonParam
    * @param onSuccess
    * @param onError
    * @return
    */
   @Post(
         url = "http://{url}/{api}/",
         async = true
   )
   Future<JSONObject> asyncAlgorithmApi(@Var("url") String url, @Var("api") String api, @JSONBody JSONObject jsonParam, OnSuccess<JSONObject> onSuccess, OnError onError);

HttpConfig设置超时时间

public class HttpConfig {
   public static <T> T getConfiguration(Class<T> cl){
      ForestConfiguration configuration = ForestConfiguration.configuration();
      //设置超时时间
      configuration.setReadTimeout(1000000*1000);
      return  configuration.createInstance(cl);
   }

使用类中

/**
 * 实例化http请求接口
 */
public static final Algorithm alg;

static {
    // 实例化Forest请求接口
    alg = HttpConfig.getConfiguration(Algorithm.class);
}


public JSONObject postWarningModelResult() {
    String token=;
    //algResUrl这个值环境变量时只能写ip+端口的形式不需要加http因为在asyncModelResultApi方法中已经添加了前缀，如果环境变量想要加前缀需要将方法中的url的http去掉
    Future<String> modelResult = alg.asyncModelResultApi(algResUrl, token,调用接口需要的参数, (String result, ForestRequest request, ForestResponse response) -> {
    //获取异步调用的结果
    System.out.println("异步调用后返回的结果："+result);
    }, (ForestRuntimeException ex, ForestRequest req, ForestResponse res) -> {
    });
    return null;
}
