1、lucene包的下载地址:http://apache.etoak.com/lucene/java/3.3.0/
2、下载jdk环境
3、下载JavaBridge URL:http://sourceforge.net/projects/php-java-bridge/
步骤:
1安装好jdk
2下载的JavaBridge.jar拷到php的ext 文件夹下.
3用rar压缩软件打开javaBridge.jar找到java文件夹,该文件夹下大都是后缀是.inc格式文件.把java整个考到www/php_java/下.
4双击javaBridge.jar打开8080端口
5在php_java下写php测试文件
<?php require_once("java/Java.inc"); header("content-type:text/html; charset=utf-8"); // get instance of Java class java.lang.System in PHP $system = new Java('java.lang.System'); $s = new Java("java.lang.String", "php-java-bridge config...<br><br>"); echo $s; // demonstrate property access print 'Java version='.$system->getProperty('java.version').' <br>'; print 'Java vendor=' .$system->getProperty('java.vendor').' <br>'; print 'OS='.$system->getProperty('os.name').' '. $system->getProperty('os.version').' on '. $system->getProperty('os.arch').' <br>'; // java.util.Date example $formatter = new Java('java.text.SimpleDateFormat', "EEEE, MMMM dd, yyyy 'at' h:mm:ss a zzzz"); print $formatter->format(new Java('java.util.Date'));
?>
结果:
php-java-bridge config...

用eclipse写一个TestLucene包类命名为TxtFileIndexer.java
package TestLucene; import java.io.File; import java.io.FileReader; import java.io.Reader; import java.util.Date; import org.apache.lucene.analysis.Analyzer; import org.apache.lucene.analysis.standard.StandardAnalyzer; import org.apache.lucene.document.Document; import org.apache.lucene.document.Field; import org.apache.lucene.index.IndexWriter; import org.apache.lucene.index.Term; import org.apache.lucene.search.Hits; import org.apache.lucene.search.IndexSearcher; import org.apache.lucene.search.TermQuery; import org.apache.lucene.store.FSDirectory; public class TxtFileIndexer ...{ public String test() ...{ return "test is ok hohoho"; } /**//** * @param args */ public String createIndex(String indexDir_path,String dataDir_path) throws Exception ...{ String result = ""; File indexDir = new File(indexDir_path); File dataDir = new File(dataDir_path); Analyzer luceneAnalyzer = new StandardAnalyzer(); File[] dataFiles = dataDir.listFiles(); IndexWriter indexWriter = new IndexWriter(indexDir,luceneAnalyzer,true); long startTime = new Date().getTime(); for(int i=0; i < dataFiles.length; i++) ...{ if(dataFiles[i].isFile() && dataFiles[i].getName().endsWith(".html")) ...{ result += "Indexing file" + dataFiles[i].getCanonicalPath()+"<br />"; Document document = new Document(); Reader txtReader = new FileReader(dataFiles[i]); document.add(Field.Text("path",dataFiles[i].getCanonicalPath())); document.add(Field.Text("contents",txtReader)); indexWriter.addDocument(document); } } indexWriter.optimize(); indexWriter.close(); long endTime = new Date().getTime(); result += "It takes"+(endTime-startTime) + " milliseconds to create index for the files in directory " + dataDir.getPath(); return result; } public String searchword(String ss,String index_path) throws Exception ...{ String queryStr = ss; String result = "Result:<br />"; //This is the directory that hosts the Lucene index File indexDir = new File(index_path); FSDirectory directory = FSDirectory.getDirectory(indexDir,false); IndexSearcher searcher = new IndexSearcher(directory); if(!indexDir.exists())...{ result = "The Lucene index is not exist"; return result; } Term term = new Term("contents",queryStr.toLowerCase()); TermQuery luceneQuery = new TermQuery(term); Hits hits = searcher.search(luceneQuery); for(int i = 0; i < hits.length(); i++)...{ Document document = hits.doc(i); result += "<br /><a href='getfile.php?w="+ss+"&f="+document.get("path")+"'>File: " + document.get("path")+"</a>\n"; } return result; } }
先创建一个我们写的TxtFileIndexer类的实例,
$tf = new Java('TestLucene.TxtFileIndexer');
然后就按正常PHP类的调用方法的方式进行调用,首先创建索引:
$data_path = "F:/test/php_lucene/htdocs/data/manual"; //定义被索引内容的目录 $index_path = "F:/test/php_lucene/htdocs/data/search"; //定义生成的索引文件存放目录 $s = $tf->createIndex($index_path,$data_path); //调用Java类的方法 print $s; //打印返回的结果
$index_path = "F:/test/php_lucene/htdocs/data/search"; //定义生成的索引文件存放目录
$s = $tf->searchword("here is keyword for search",$index_path);
print $s;
java_require("F:/test/php_lucene/htdocs/lib/"); //这是个例子,我的类和Lucene都放到这个目录下,这样就可以了,是不是很简单。
测试代码<?php error_reporting(0); java_require("F:/test/php_lucene/htdocs/lib/"); $tf = new Java('TestLucene.TxtFileIndexer'); $s = $tf->test(); print "TestLucene.TxtFileIndexer->test()<br />".$s; echo "<hr />"; $data_path = "F:/test/php_lucene/htdocs/data/manual"; $index_path = "F:/test/php_lucene/htdocs/data/search"; if({1}
GET["action"] == "create") ...{ $s = $tf->createIndex($index_path,$data_path); print $s; }else ...{ echo "<form method=get> <input type=text name=w /><input type=submit value=search /><br />"; if({1}
GET["w"] != "") ...{ $s = $tf->searchword({1}
GET["w"],$index_path); print $s; } }?>
