IK 用java 代码实现分词

需要导入IK 对应的jar 包

IKAnalyzer2012.jar

lucene-core-4.10.jar

public static void main(String[] args) throws IOException {
       //  String text="基于java语言开发的轻量级的中文分词工具包";  
         String text="宋祖英语培训班、周渝民政服务中心、容祖儿童医院、吴奇隆胸医院、苏永康复中心、梁朝伟哥专卖、陈冠希望小学、吴彦祖传中医坊、林书豪华酒店";  
　　　　　　//创建分词对象  

            Analyzer anal=new IKAnalyzer(true);       
            StringReader reader=new StringReader(text);  
            //分词  
            TokenStream ts=anal.tokenStream("", reader);  
            CharTermAttribute term=ts.getAttribute(CharTermAttribute.class);  
            //遍历分词数据  
            ts.reset();
            while(ts.incrementToken()){  
                System.out.print(term.toString()+"|");  
            }      
            ts.close();
            reader.close();  
            System.out.println();  

        
    }

分词结果：

宋祖英|语|培训班|周渝民|政|服务中心|容祖儿|童|医院|吴奇隆|胸|医院|苏永康|复|中心|梁朝伟|哥|专卖|陈冠希|望|小学|吴彦祖|传|中医|坊|林|书|豪华酒店|

         String text = "据说WWDC要推出iPhone6要出了？与iPhone5s相比怎样呢？@2014巴西世界杯";

public static  String spiltword(String str) {
        String datas = "";
        Analyzer anal = new IKAnalyzer(true);
        StringReader reader = new StringReader(str);
        TokenStream ts ;
        try {
            ts = anal.tokenStream("", reader);
            CharTermAttribute term = ts.getAttribute(CharTermAttribute.class);
            // 遍历分词数据
            ts.reset();
            while (ts.incrementToken()) {
                datas += ts.toString() +"
";
            }
            ts.close();
            reader.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return datas;
    }

分词结果：
