集成Hibernate Search做全文检索

版本及依赖：

<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-search-orm</artifactId>
			<version>4.2.0.Final</version>
		</dependency>

<dependency>
			<groupId>org.apache.lucene</groupId>
			<artifactId>lucene-smartcn</artifactId>
			<version>3.6.2</version>
		</dependency>

1、修改hibernate主配置文件，增加：

<property name="hibernate.search.default.directory_provider">
			org.hibernate.search.store.impl.FSDirectoryProvider
		</property>
		<property name="hibernate.search.default.indexBase">
			e:\luceneLinde
		</property>

一个是存储的实现，一个是存储的路径

2、给实体类上注解

import javax.persistence.*;

import org.hibernate.annotations.GenericGenerator;

import org.hibernate.search.annotations.DocumentId;
import org.hibernate.search.annotations.Field;
import org.hibernate.search.annotations.Indexed;
import org.hibernate.search.annotations.IndexedEmbedded;
import org.hibernate.search.annotations.Store;


@Entity
@Table(name = "PAGEINFO")
@Indexed(index="PageInfo")/*标记该表可索引，参数index指定存放索引信息的文件名，路径在主配置文件中指定*/

@Analyzer(impl=SmartChineseAnalyzer.class)//分词器
public class Pageinfo implements java.io.Serializable {
	private static final long serialVersionUID = 5454155825314635342L;


		
	// columns START
//省略1000字
	// columns END

	@Id
	@GeneratedValue(generator = "custom-id")
	@GenericGenerator(name = "custom-id", strategy = "uuid")
	@Column(name = "ID", unique = true, nullable = false, insertable = true, updatable = true, length = 32)
	@DocumentId  /*以字段id作为文档id*/
	public java.lang.String getId() {
		return this.id;
	}

	@Column(name = "TITLE", unique = false, nullable = true, insertable = true, updatable = true, length = 255)
	@Field(store=Store.NO)  /*可索引，但不存储*/
	public java.lang.String getTitle() {
		return this.title;
	}

	@Column(name = "CONTENT", unique = false, nullable = true, insertable = true, updatable = true)
	@Field(store=Store.NO)
	public java.lang.String getContent() {
		return this.content;
	}

	@Column(name = "SOURCE", unique = false, nullable = true, insertable = true, updatable = true)
	@Field(store=Store.NO)
	public java.lang.String getSource() {
		return this.source;
	}


	@Column(name = "SUMMARY", unique = false, nullable = true, insertable = true, updatable = true)
	@Field(store=Store.NO)
	public java.lang.String getSummary() {
		return this.summary;
	}


	@ManyToOne(cascade = {}, fetch = FetchType.LAZY)
	@JoinColumns({ @JoinColumn(name = "SITE_ID", nullable = false, insertable = false, updatable = false) })
	@IndexedEmbedded(prefix="site_",depth=1)  /*关联检索，如field为site_name实则是按关联表的那么属性检索*/
	public GrabageSiteconfig getGrabageSiteconfig() {
		return grabageSiteconfig;
	}

}

省略了大量东西，如域成员，set方法等，一般以id作为doc的id，其他的你想对哪些字段做全文检索，就使用@Field标记，至于其store属性和lucene中的含义一致，不赘述。

3、使用API

package othertest;

import java.util.Iterator;
import java.util.List;

import javacommon.gather.bean.Pageinfo;

import org.apache.lucene.analysis.standard.StandardAnalyzer;
import org.apache.lucene.queryParser.ParseException;
import org.apache.lucene.queryParser.QueryParser;
import org.apache.lucene.search.Query;
import org.apache.lucene.util.Version;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.search.FullTextQuery;
import org.hibernate.search.FullTextSession;
import org.hibernate.search.Search;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;

public class SearchTest {
	private static SessionFactory sf;
	
	@BeforeClass
	public static void init() {
		sf = HibernateConfigTest.sf;//弄一个SessionFactory，不多说
		
	}
	@Before
	//执行索引
	public void index(){
		Session session = sf.openSession();
		FullTextSession fullTextSession = Search.getFullTextSession(session);
		//查出结果
		List<Pageinfo> pageinfos = session.createCriteria(Pageinfo.class).list();
		session.beginTransaction();
		//依次建立索引
		for (Iterator iterator = pageinfos.iterator(); iterator.hasNext();) {
			Pageinfo pageinfo = (Pageinfo) iterator.next();
			fullTextSession.index(pageinfo);
		}
		session.getTransaction().commit();
		session.close();
		System.out.println("index over......");
	}

	@Test
	public void searchTest() {
		Session session = sf.openSession();
		FullTextSession fullTextSession = Search.getFullTextSession(session);
		//在字段content中检索
		QueryParser queryParser = new QueryParser(Version.LUCENE_36, "content", new SmartChineseAnalyzer(Version.LUCENE_36));
		Query luceneqQuery=null;
		try {
			//检索含有“大风”的信息
			luceneqQuery = queryParser.parse("大风");
		} catch (ParseException e) {
			e.printStackTrace();
		}
		//执行检索，得到结果集
		FullTextQuery fullTextQuery = fullTextSession.createFullTextQuery(luceneqQuery, Pageinfo.class);
		List<Pageinfo> pageinfos = fullTextQuery.list();
		//查看结果做验证
		for (Iterator iterator = pageinfos.iterator(); iterator.hasNext();) {
			Pageinfo pageinfo = (Pageinfo) iterator.next();
			System.out.println(pageinfo.getContent());
		}
	}
}
