最简单的支持中文的示例

需要先设置classpath包含lucene-*.*.jar 和 CJKAnalyzer.class及相关类的包
建立索引：
import java.io.*;
import java.text.*;
import java.util.*;
import org.apache.lucene.analysis.cjk.CJKAnalyzer;
import org.apache.lucene.document.*;
import org.apache.lucene.index.*;
public class Mp3Indexer
{
public final static String mp3Path="E://悦耳_music//new songs";//mp3所在目录
public final static String indexPath="d://mp3Indexer";//索引存放目录
public static void main(String[] args) throws ClassNotFoundException, IOException{
try {
IndexWriter writer = new IndexWriter(indexPath, new CJKAnalyzer(), true);
indexMp3s(writer, new File(mp3Path));
System.out.println("优化中....");
writer.optimize();
writer.close();
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
public static void indexMp3s(IndexWriter writer, File file) throws Exception {
if (file.isDirectory()) {
String[] files = file.list();
for (int i = 0; i < files.length; i++) {
indexMp3s(writer, new File(file, files[i]));
}
}
else if (file.getPath().endsWith(".mp3")) { //只对 MP3 文件做索引
System.out.print("正在处理文件:" + file + " ....");
// Add mp3 file ....
Document doc = new Document();
doc.add(Field.Text("name", file.getName())); //索引文件名
doc.add(Field.UnIndexed("modified", DateFormat.getDateTimeInstance().format(new Date(file.lastModified())))); //索引最后修改时间
System.out.println("[处理完成]");
writer.addDocument(doc);
} //end else if
}
} //end class
