java - 如何使用 Lucene Analyzer 标记字符串？

Question

有没有一种简单的方法可以使用 Lucene 的 Analyzer 的任何子类来解析/标记 String？

类似:

String to_be_parsed = "car window seven";
Analyzer analyzer = new StandardAnalyzer(...);
List<String> tokenized_string = analyzer.analyze(to_be_parsed);

Answer 1

根据上面的答案，这稍作修改以与 Lucene 4.0 一起使用。

public final class LuceneUtil {

  private LuceneUtil() {}

  public static List<String> tokenizeString(Analyzer analyzer, String string) {
    List<String> result = new ArrayList<String>();
    try {
      TokenStream stream  = analyzer.tokenStream(null, new StringReader(string));
      stream.reset();
      while (stream.incrementToken()) {
        result.add(stream.getAttribute(CharTermAttribute.class).toString());
      }
    } catch (IOException e) {
      // not thrown b/c we're using a string reader...
      throw new RuntimeException(e);
    }
    return result;
  }

}
