Question

我正在尝试对推文进行情绪分析，但会遇到奇怪的异常。

我正在使用属性文件初始化管道，并将属性文件放在资源目录中的src-＆gt;主文件夹中。

但仍然在init函数中获得Exception：

Exception in thread "main" edu.stanford.nlp.io.RuntimeIOException:    java.io.IOException: Unable to open "edu/stanford/nlp/models/lexparser/englishPCFG.ser.gz" as class path, filename or URL

at com.mycompany.sentmentanalysisontweets.NLP.init(NLP.java:27)
at com.mycompany.sentmentanalysisontweets.WhatToThink.main(WhatToThink.java:15)

在主要方法中，我调用init()方法。

public class Main {

    public static void main(String[] args) {
        NLP.init();
    }
}

class NLP {
    static StanfordCoreNLP pipeline;

    public static void init() {
        InputStream input = NLP.class.getClass().getResourceAsStream("/example.properties");
        Properties prop = new Properties();
        try {
          prop.load(input);
        } catch (IOException e) {
          e.printStackTrace();
        }

        pipeline = new StanfordCoreNLP(prop);
    }
}

具有以下结构：

src/main/resources
             |
              - example.properties

执行以下代码可以解决您的问题：

public class Main {

    public static void main(String[] args) {
        NLP.init();
    }
}

class NLP {
   static StanfordCoreNLP pipeline;

   public static void init() {
        InputStream input = NLP.class.getClass().getResourceAsStream("/example.properties");
        Properties prop = new Properties();
        try {
            prop.load(input);
        } catch (IOException e) {
            e.printStackTrace();
        }

        pipeline = new StanfordCoreNLP(prop);
    }
}

修改

您的pom.xml必须包含以下依赖项：

<dependencies> <dependency> <groupId>edu.stanford.nlp</groupId> <artifactId>stanford-corenlp</artifactId> <version>3.6.0</version> </dependency> <dependency> <groupId>edu.stanford.nlp</groupId> <artifactId>stanford-corenlp</artifactId> <version>3.6.0</version> <classifier>models</classifier> </dependency> </dependencies>

Answer 2

使用

            InputStream input = new FileInputStream(new File("./", "example.properties"));

而不是

            InputStream input = StanfordCoreNLP.class.getClass().getResourceAsStream("/example.properties");

将解决问题

Stanford CoreNLP属性文件未找到
