我在Java代码库中使用了finagle scala库。
下面是finagle中用scala代码编写的示例代码。
import com.twitter.finagle.Http;
import com.twitter.finagle.transport.Transport;
public class FinagleClientDemo {
public static void main(String[] args) {
Http.Client client = Http.client()
.withLabel("myLabel");
client.withDecompression(true);
Transport.Liveness liveness = client.params().apply(Transport.Liveness.param());
}
}
我在Java中编写了以下内容-
[error] /Users/myuser/Documents/chapter14/src/main/java/FinagleClientDemo.java:9:1: cannot find symbol
[error] symbol: method param()
[error] location: class com.twitter.finagle.transport.Transport.Liveness
[error] Transport.Liveness liveness = (Transport.Liveness)Http.client().params().apply(Transport.Liveness.param());
[error] (Compile / compileIncremental) javac returned non-zero exit code
[error] Total time: 4 s, completed Nov 6, 2018 1:10:43 PM
2. Waiting for source changes in project chapter14... (press enter to interrupt)
当我编译程序时,我得到以下错误-
{{1}}
我在这里犯了什么错误。如何使我的程序编译?
答案 0 :(得分:0)
答案是
Transport.Liveness liveness = client.params().apply(Transport.Liveness$.MODULE$.param());
