Lucene5.3.1 使用的简单实例（待9月更新）

Lucene是一个基于Java的开源全文信息检索工具包。

MyTest.Java

public class MyTest { /// 存放需要分析的文件的地址 private static String FILE_PATH = "/Users/zoujs/Desktop/test4lucene"; // 存放索引的位置 private static String INDEX_PATH = "/Users/zoujs/Desktop/index4lucene"; @Test public void createIndex() { IndexUtils.createIndex(INDEX_PATH, FileUtils.loadFiles(FILE_PATH)); } @Test public void searchIndex() { SearcherUtils.search(INDEX_PATH, "title", "china"); } }

FileBean.java

public class FileBean implements Serializable{ private String title; private String content; private int id; public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } public int getId() { return id; } public void setId(int id) { this.id = id; } @Override public String toString() { return "FileBean{" + "title='" + title + '\'' + ", content='" + content + '\'' + ", id=" + id + '}'; } }

IndexUtils.java

public class IndexUtils { public static void createIndex(String indexPath, List<FileBean> files) { Directory directory = null; try { if (StringUtils.isBlank(indexPath)) directory = new RAMDirectory(); else directory = FSDirectory.open(Paths.get(indexPath)); // 获取分析器 Analyzer analyzer = new StandardAnalyzer(); //标准分析器 // IndexWriter的配置 IndexWriterConfig indexWriterConfig = new IndexWriterConfig(analyzer); indexWriterConfig.setOpenMode(IndexWriterConfig.OpenMode.CREATE); //无索引文件则创建，有则在后面继续添加 // 创建IndexWriter IndexWriter writer = new IndexWriter(directory, indexWriterConfig); // 遍历文件Bean创建索引 for (FileBean bean : files) { // 创建Document Document doc = new Document(); // 为Document创建三个字段 id title content doc.add(new IntField("id", bean.getId(), IntField.TYPE_STORED)); doc.add(new Field("title", bean.getTitle(), TextField.TYPE_STORED)); doc.add(new TextField("content", bean.getContent(), Field.Store.YES)); // 将Document写入IndexWriter writer.addDocument(doc); } // 提交 writer.commit(); writer.close(); } catch (Exception e) { e.printStackTrace(); } } }

SearchUtils.java

public class SearcherUtils { public static void search(String indexPath, String field, String text) { try { // 索引文件目录 Directory directory = FSDirectory.open(Paths.get(indexPath)); // 获取IndexReader DirectoryReader reader = DirectoryReader.open(directory); IndexSearcher searcher = new IndexSearcher(reader); Term term = new Term(field, text); Query query = new TermQuery(term); TopDocs topDocs = searcher.search(query, 10); ScoreDoc[] hits = topDocs.scoreDocs; if (null != hits) for (int i = 0; i < hits.length; i++) { Document doc = searcher.doc(hits[i].doc); System.out.println(doc.get("title")); } reader.close(); } catch (Exception e) { e.printStackTrace(); } } } 相关资源：最新全文检索 lucene-5.2.1 入门经典实例
