设置我自己的 Stanford CoreNLP 服务器的问题：

Question

我正在按照 http://stanfordnlp.github.io/CoreNLP/corenlp-server.html 中的教程设置我自己的斯坦福解析器服务器。但是，当我粘贴示例代码时，出现错误：

Exception in thread "Thread-1" edu.stanford.nlp.io.RuntimeIOException: Could not connect to server: localhost:9000

这是我的代码：

import java.util.*;
import edu.stanford.nlp.pipeline.Annotation;
import edu.stanford.nlp.pipeline.StanfordCoreNLPClient;

public class tagger {
    public static void test(){
        // creates a StanfordCoreNLP object with POS tagging, lemmatization, NER, parsing, and coreference resolution
        Properties props = new Properties();

        props.setProperty("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");

        StanfordCoreNLPClient pipeline = new StanfordCoreNLPClient(props, "localhost", 9000, 2);
        // read some text in the text variable
        String text = "How are you today?";
        // create an empty Annotation just with the given text
        Annotation document = new Annotation(text);
        // run all Annotators on this text
        pipeline.annotate(document);
    }

    public static void main(String[] args){
        test();
    }
}

你提供的代码对我来说没有改变。（它不打印任何东西；你可以尝试在 test() 的末尾添加 System.out.println(document.toShorterString()); 之类的东西，同时测试它，但它有效......）

您是否使用此处的第一条指令 http://stanfordnlp.github.io/CoreNLP/corenlp-server.html#getting-started 启动了服务器并将其保留运行？这看起来服务器不在您本地计算机的端口 9000 上运行。
