3:配置session共享,方式很多,這里用的redis的session共享(兼容jdk版本至少1.7):
    tomcat的lib包加commons-pool2-2.0.jar,jedis-2.5.2.jar,tomcat-redis-session-manager1.2.jar;
    tomcat配置文件context.xml,在標簽<Context>內添加配置:
        <Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
4:項目里面區分session的代碼:
    (1):放session的接口(執行一次);
    (2):取session數據(不斷刷新),看tomcat打印信息;
5:效果,http://www.nimenhaihaoma.com/redis3.2/getRedis.action (狂刷session值相同)

1，添加索引文件中的一條新的索引     
                Question addQ = new Question();//新添加的一條數據,對象id在索引文件中沒有
                addQ.setId("999999999");
                addQ.setQuestionname("新添加的一條數據名稱");

                Analyzer sa = new SmartChineseAnalyzer(Version.LUCENE_40);

IndexWriterConfig iwc = new IndexWriterConfig(Version.LUCENE_40, sa);

iwc.setOpenMode(OpenMode.APPEND);

IndexWriter writer = null;

try {

Directory dir1 = FSDirectory.open(new File("F:\\temp"));

writer = new IndexWriter(dir1, iwc);

FieldType ft = new FieldType();

ft.setIndexed(true);

ft.setStored(true);

ft.setTokenized(true);

FieldType ft2 = new FieldType();

ft2.setIndexed(true);

ft2.setStored(true);

ft2.setTokenized(false);

Document doc = new Document();

doc.add(new Field("id", addQ.getId(), ft2));

doc.add(new Field("questionname", addQ.getQuestionname(), ft));

writer.addDocument(doc);

writer.close();

} catch (CorruptIndexException e) {

e.printStackTrace();

} catch (LockObtainFailedException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

} finally{

try {

if(writer!=null){

writer.close();

}

if(sa!=null){

sa.close();

}

} catch (CorruptIndexException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

                IndexReader reader = DirectoryReader.open(FSDirectory.open(new File("F:\\temp")));// 打開索引

IndexSearcher searcher = new IndexSearcher(reader);

Analyzer analyzer = new SmartChineseAnalyzer(Version.LUCENE_40);

String[] fields = { "questionname","id" };

Occur[] occurs = new Occur[] { Occur.SHOULD,Occur.SHOULD };

Query query =  MultiFieldQueryParser.parse(Version.LUCENE_40, "測試 的", fields,

occurs, analyzer);

TopDocs result = searcher.search(query, searcher.getIndexReader()

.maxDoc());

ScoreDoc[] hits = result.scoreDocs;

List<Document> list = new ArrayList<Document>();

for (int i = 0; i <hits.length; i++) {

Document doc = searcher.doc(hits[i].doc);

list.add(doc);

}

System.out.println("搜索list的長度\t→→→→\t"+list.size());

for (Document document : list) {

System.out.println(document.getField("questionname"));

}

analyzer.close();

注：紅色字體是輸入的檢索條件，多個用空格隔開，找到的結果先匹配同時符合多個的結果，結果只是拿過來的document一個list集合，具體結果再解析就行了。

結果如圖：

                Connection conn = null;

Statement stat = null;

ResultSet rs = null;

Analyzer sa = new SmartChineseAnalyzer(Version.LUCENE_40);

IndexWriterConfig iwc = new IndexWriterConfig(Version.LUCENE_40, sa);

iwc.setOpenMode(OpenMode.CREATE);

Directory dir1 = FSDirectory.open(new File("F:\\temp"));

IndexWriter writer = new IndexWriter(dir1, iwc);

int numIndexed = -1;

FieldType ft = new FieldType();

ft.setIndexed(true);

ft.setStored(true);

ft.setTokenized(true);

FieldType ft2 = new FieldType();

ft2.setIndexed(true);

ft2.setStored(true);

ft2.setTokenized(false);

Class.forName("com.mysql.jdbc.Driver");

conn = (Connection) DriverManager.getConnection(

"jdbc:mysql:///question", "root", "root");

stat = (Statement) conn.createStatement();

rs = stat.executeQuery("select id,questionname from question");

List<String> list = new ArrayList<String>();

while (rs.next()) {

String id = rs.getString("questionname");

String questionname = rs.getString("questionname");

list.add(id);

list.add(questionname);

}

rs.close();

stat.close();

conn.close();

for (String string : list) {

Document doc = new Document();

doc.add(new Field("questionname", string, ft2));

writer.addDocument(doc);

}

numIndexed = writer.maxDoc();

writer.close();
執行完這段程序f盤多一個文件夾temp，里面就是創建好的索引文件了，然后進行根據索引文件查詢
