需要匯入jar：

public class IKAnalyze {

    //分詞器
@Test
public void test() throws Exception {
        //String word="a good person,Happy Every Day";
        //String word="我為何不哭，因為我僅存的，就只有堅強了";
String word="中華人民共和國KWWL  DRGYBN，北大老鳥，我們是";
        //Analyzer analyzer = new StandardAnalyzer();//一元分詞
// Analyzer analyzer=new CJKAnalyzer();  //
 
二元分詞
// Analyzer analyzer=new SmartChineseAnalyzer();  //智慧中文分詞
//IK分詞
Analyzer analyzer=new IKAnalyzer(true);
        testAnalyzer(analyzer,word);
    }
    //使用指定的分詞器對指定的文字進行分詞
public  void testAnalyzer(Analyzer analyzer, String text) throws Exception {
        System.out.println("分詞器：" + analyzer.getClass());
        StringReader reader= new 
 
StringReader(text);
        TokenStream tokenStream = analyzer.tokenStream("content",reader);
        tokenStream.reset();
        CharTermAttribute cta =tokenStream.addAttribute(CharTermAttribute.class);
        while (tokenStream.incrementToken()) {
            System.out.println(cta);
        }
        reader.close();
    }
