Mongo 在Java中使用总结

1.in字句的使用：

  Map<String, Object> condMap = new HashMap<String, Object>();    Pattern pattern = Pattern.compile("YichengYunwei_XunjianRenwu", Pattern.CASE_INSENSITIVE);      condMap.put("taskCode", pattern);    DBCursor taskCur = this.basicDAO.find(Constants.Table_TASK, condMap);    logger.debug("queryBussineURL taskdbCursor="+taskCur);
