Lucene建立索引

標籤：lucene建立索引

1.建立Java項目(lucene)

2.建立CreateIndex類,包名(com.zhishang.lucenc)

package com.zhishang.lucene;import org.apache.commons.io.FileUtils;import org.apache.lucene.analysis.Analyzer;import org.apache.lucene.analysis.standard.StandardAnalyzer;import org.apache.lucene.document.*;import org.apache.lucene.index.IndexWriter;import org.apache.lucene.index.IndexWriterConfig;import org.apache.lucene.store.Directory;import org.apache.lucene.store.FSDirectory;import org.apache.lucene.util.Version;import org.junit.Test;import java.io.File;import java.io.IOException;/** * Created by Administrator on 2017/7/7. */public class CreateIndex {    public static final String indexDir = "G:/index";    public static final String dataDir = "G:/data";    @Test    public void createIndex(){        try {            Directory dir = FSDirectory.open(new File(indexDir));            //分詞器            Analyzer analyzer = new StandardAnalyzer(Version.LUCENE_4_9);            IndexWriterConfig config = new IndexWriterConfig(Version.LUCENE_4_9,analyzer);            config.setOpenMode(IndexWriterConfig.OpenMode.CREATE_OR_APPEND);            IndexWriter writer = new IndexWriter(dir,config);            File file = new File(dataDir);            File[] files = file.listFiles();            for(File f:files){                Document doc = new Document();                doc.add(new StringField("filename",f.getName(), Field.Store.YES));                doc.add(new TextField("content", FileUtils.readFileToString(f),Field.Store.YES));                doc.add(new LongField("lastmodify",f.lastModified(), Field.Store.YES));                writer.addDocument(doc);            }            writer.close();        } catch (IOException e) {            e.printStackTrace();        }    }}

3.運行CreateIndex函數,查看G:/index下產生的檔案
