Question

我正在尝试以下代码来获取泰语句子的所有令牌。它抛出异常。有没有人能指出我在JAVA中用泰语标记？

    import org.apache.lucene.analysis.Analyzer.TokenStreamComponents;
import org.apache.lucene.analysis.TokenFilter;
import org.apache.lucene.analysis.TokenStream;
import org.apache.lucene.analysis.icu.ICUNormalizer2Filter;
import org.apache.lucene.analysis.icu.segmentation.ICUTokenizer;
import org.apache.lucene.analysis.tokenattributes.CharTermAttribute;

public class Tokenizer{

    public static void main(String[] args) throws IOException {
        ICUTokenizer tokenizer = new ICUTokenizer(new StringReader("การที่ได้ต้องแสดงว่างานดี"));
        TokenFilter filter = new ICUNormalizer2Filter(tokenizer);
        TokenStreamComponents tt = new TokenStreamComponents(tokenizer, filter);
        TokenStream ts = tt.getTokenStream();
        CharTermAttribute cattr  = ts.addAttribute(CharTermAttribute.class);
        ts.reset();
        while(ts.incrementToken()){
            System.out.println(cattr.toString()+"-----");
        }
    }
}

例外如下

Exception in thread "main" java.lang.ExceptionInInitializerError
    at org.apache.lucene.analysis.icu.segmentation.ICUTokenizer.<init>(ICUTokenizer.java:72)
    at com.tokenizer.tt.main(tt.java:22)

最后想出了如何在java程序中使用ICU4J

import java.io.IOException;
import java.io.Reader;
import java.io.StringReader;
import org.apache.lucene.analysis.icu.segmentation.ICUTokenizer;
import org.apache.lucene.analysis.tokenattributes.CharTermAttribute;

public class icuEstes {

public static void main(String[] args) throws IOException {
    Reader reader = new StringReader("การที่ได้ต้องแสดงว่างานดี  This is a test ກວ່າດອກ");
    ICUTokenizer icut = new ICUTokenizer();
    icut.setReader(reader);
    icut.addAttribute(CharTermAttribute.class);
    icut.reset();
    while (icut.incrementToken()) {
        System.out.println(icut.toString());
        System.out.println(icut.getAttribute(CharTermAttribute.class));
    }
    icut.close();
}}

用ICUTokenizer JAVA标记泰语句子
