使用Lucene和IKAnalyzer做字符串分词的实例

// 添加搜索记录
	@Transactional
	private void addSearchLog(String content) throws IOException {
		if(!StringUtils.isEmpty(content)){
			// 分词
			StringReader sr = new StringReader(content);
			IKSegmenter ik = new IKSegmenter(sr, true);
			Lexeme lex = null;
			SearchLog searchLog = null;
			while ((lex = ik.next()) != null) {
				searchLog = searchLogDao.getSearchLog(lex.getLexemeText());
				if(searchLog == null){
					searchLog = new SearchLog();
					searchLog.setLogCount(1);
					searchLog.setName(lex.getLexemeText());
					searchLogDao.save(searchLog);
				}else{
					searchLog.setLogCount(searchLog.getLogCount() + 1);
					searchLogDao.save(searchLog);
				}
			}
	
			long count = searchLogDao.count();
	
			// 删除多出总记录的记录数据
			if (count > 1000) {
				List<SearchLog> lastLogList = searchLogDao.getSearchLog(new PageRequest(0, (int)count - 1000, Direction.ASC, "lastTime","logCount"));
				List<Long> ids = new ArrayList<Long>();
				for (int i = 0; i < lastLogList.size(); i++) {
					ids.add(lastLogList.get(i).getId());
				}
				searchLogDao.deleteLastSearchLog(ids);
			}
		}
