在Java代码中没有找到配置FIAGLE的合适方法

twitter-finagle finagle scala

我有Java多语言应用程序,主要有Java代码,并且很少使用Scala库。

下面的scala代码编译得很好。

import com.twitter.finagle.Http.Client
import com.twitter.finagle.Http
import com.twitter.finagle.param.Logger

object Main extends App {

  private val loggerFinagle = java.util.logging.Logger.getLogger("FinagleLogger")

  val client: Client = Http.client
    .configured(Logger(loggerFinagle))
}

我用java编写与下面相同的代码

import com.twitter.finagle.Http;
import com.twitter.finagle.param.Logger;

public class JavaMain {
    public static void main(String[] args) {

        java.util.logging.Logger loggerFinagle = java.util.logging.Logger.getLogger("FinagleLogger");

        Http.client()
               .configured(new Logger(loggerFinagle));
    }
}

当我编译代码时,我会得到下面的错误-

看起来我必须通过这个元组,但我不知道怎么做。

Github的项目是 here .

以下是我的项目的依赖项详细信息-

scala版本-2.12.6

Java版本-1.80Y151

finagle版本-7.1.0

According to the docs ,您需要拨打 mk() 方法,因此类似下面的内容应该创建适当的元组:

    Http.client()
           .configured(new Logger(loggerFinagle).mk());
