---  2010-06-18 17:00 代码修改： 修改重复创建索引，添加双字段高亮。


 

   今天发一个简单的和数据库交互的Lucene示例，只是初步的靠Lucene自带的分词实现中文分词,效果肯定没有网上琳琅的分词器相媲美，只为了示例，用了自带的高亮。页面不好看，将就一下哦。

    主要是由 Spring + Struts1 + Mysql 5 实现， 只是为了实现功能。请各位大侠拍砖。

    好了，不多说了。贴代码：

 

    1. T_ARTICLE 表

Java代码 
DROP TABLE IF EXISTS `t_article`;  
CREATE TABLE `t_article` (  
  `ID` varchar(32) NOT NULL default '',  
  `ARTICLE_TITLE` varchar(255) default NULL,  
  `ARTICLE_TAG` varchar(255) default NULL,  
  `ARTICLE_CONTENT` text,  
  PRIMARY KEY  (`ID`)  
) ENGINE=InnoDB DEFAULT CHARSET=utf8; 

DROP TABLE IF EXISTS `t_article`;
CREATE TABLE `t_article` (
  `ID` varchar(32) NOT NULL default '',
  `ARTICLE_TITLE` varchar(255) default NULL,
  `ARTICLE_TAG` varchar(255) default NULL,
  `ARTICLE_CONTENT` text,
  PRIMARY KEY  (`ID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;    上面的数据 随便加一下吧，主要是article_content和article_title字段的数据，article_content是个text字段，所以你可以粘贴网页的文字内容添加到本字段中。

 

    2.业务接口 ArticleService.java

 

Java代码 
package com.jushi.lucene.business;  
 
import java.util.List;  
import com.jushi.lucene.entities.Article;  
/** 
 * @Author jushi 
 * @CreateDate Jun 4, 2010 1:24:42 PM 
 * @Version V 1.0 
 */ 
 
public interface IArticleService {  
 
    public List<Article> getArticles(String query);  
 
    public boolean createIndex();  
 
} 

package com.jushi.lucene.business;

import java.util.List;
import com.jushi.lucene.entities.Article;
/**
 * @Author jushi
 * @CreateDate Jun 4, 2010 1:24:42 PM
 * @Version V 1.0
 */

public interface IArticleService {

 public List<Article> getArticles(String query);

 public boolean createIndex();

}


   3. 接口的实现 ArticleServiceImpl.java 主要的业务在这里实现：创建索引，搜索数据处理。

  }
 }
 
 public void setArticleDAO(IArticleDAO articleDAO) {
  this.articleDAO = articleDAO;
 }

}

    4. DAO 接口及 DAO实现　

 

Java代码 
public interface IArticleDAO {  
 
    public List<Article> getArticles();  
} 

public interface IArticleDAO {

 public List<Article> getArticles();
}

 

Java代码 
public class ArticleDAOImpl extends JdbcDaoSupport implements IArticleDAO{  
 
    public List<Article> getArticles() {  
        String sql = "SELECT article_title, article_tag, article_content FROM t_article";  
        return (List<Article>)this.getJdbcTemplate().query(sql, new ArticleRowMapper());  
    }  
 
} 

public class ArticleDAOImpl extends JdbcDaoSupport implements IArticleDAO{

 public List<Article> getArticles() {
  String sql = "SELECT article_title, article_tag, article_content FROM t_article";
  return (List<Article>)this.getJdbcTemplate().query(sql, new ArticleRowMapper());
 }

}

   5. 上面DAO需要的 ArticleRowMapper: 这里做了下小改动

 

Java代码 
package com.jushi.lucene.rowmapper;  
 
import java.sql.ResultSet;  
import java.sql.ResultSetMetaData;  
import java.sql.SQLException;  
 
import org.springframework.jdbc.core.RowMapper;  
 
import com.jushi.lucene.entities.Article;  
 
/** 
 * @Author jushi 
 * @CreateDate Jun 4, 2010 1:31:54 PM 
 * @Version V 1.0 
 */ 
public class ArticleRowMapper implements RowMapper {  
 
    public Object mapRow(ResultSet rs, int rowNum) throws SQLException {  
        Article article = new Article();  
        ResultSetMetaData meta = rs.getMetaData();  
        int colNum = meta.getColumnCount();  
        for (int i = 1; i <= colNum; i++) {  
            String colName = meta.getColumnName(i).toLowerCase();  
            if ("article_title".equals(colName)) {  
                article.setTitle(rs.getString(i));  
            } else if ("article_content".equals(colName)) {  
                article.setContent(rs.getString(i));  
            } else if ("article_tag".equals(colName)) {  
                article.setTag(rs.getString(i));  
                //...  
            }  
        }  
        return article;  
    }  
} 

package com.jushi.lucene.rowmapper;

import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;

import org.springframework.jdbc.core.RowMapper;

import com.jushi.lucene.entities.Article;

/**
 * @Author jushi
 * @CreateDate Jun 4, 2010 1:31:54 PM
 * @Version V 1.0
 */
public class ArticleRowMapper implements RowMapper {

 public Object mapRow(ResultSet rs, int rowNum) throws SQLException {
  Article article = new Article();
  ResultSetMetaData meta = rs.getMetaData();
  int colNum = meta.getColumnCount();
  for (int i = 1; i <= colNum; i++) {
   String colName = meta.getColumnName(i).toLowerCase();
   if ("article_title".equals(colName)) {
    article.setTitle(rs.getString(i));
   } else if ("article_content".equals(colName)) {
    article.setContent(rs.getString(i));
   } else if ("article_tag".equals(colName)) {
    article.setTag(rs.getString(i));
    //...
   }
  }
  return article;
 }
}
 

   6. Article 实体 添加了两个属性: TotalHits, TotalTime

 

Java代码 
package com.jushi.lucene.entities;  
 
/** 
 * @Author jushi 
 * @CreateDate Jun 4, 2010 1:18:48 PM 
 * @Version V 1.0 
 */ 
public class Article {  
 
    private String title;  
    private String content;  
    private String tag;  
    private int TotalHits; //命中率  
    private int TotalTime; //花费时间  
      
    public int getTotalTime() {  
        return TotalTime;  
    }  
    public void setTotalTime(int totalTime) {  
        TotalTime = totalTime;  
    }  
    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 String getTag() {  
        return tag;  
    }  
    public void setTag(String tag) {  
        this.tag = tag;  
    }  
    public int getTotalHits() {  
        return TotalHits;  
    }  
    public void setTotalHits(int totalHits) {  
        TotalHits = totalHits;  
    }  
      
} 

package com.jushi.lucene.entities;

/**
 * @Author jushi
 * @CreateDate Jun 4, 2010 1:18:48 PM
 * @Version V 1.0
 */
public class Article {

 private String title;
 private String content;
 private String tag;
 private int TotalHits; //命中率
 private int TotalTime; //花费时间
 
 public int getTotalTime() {
  return TotalTime;
 }
 public void setTotalTime(int totalTime) {
  TotalTime = totalTime;
 }
 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 String getTag() {
  return tag;
 }
 public void setTag(String tag) {
  this.tag = tag;
 }
 public int getTotalHits() {
  return TotalHits;
 }
 public void setTotalHits(int totalHits) {
  TotalHits = totalHits;
 }
 
}
 

   7. Spring 的配置如下：

   --- applicationContext-lucene.xml

 

Java代码
