如下代码有点太粗了，能提供个更方便的解决方案吗，类似hibernate，直接获取某指定的值

        try { 
            List<Object[]> list = ConnectionManager.excuteQuery("select * from t"); 
            for (int i = 0; i < list.size(); i++) { 
                Object[] os = list.get(i); 
                for(Object o : os){ 
                    if (o instanceof String) { 
                        String s = (String) o; 
                        String newStr = new String(s.getBytes("ISO-8859-1"),"GBK"); 
                        System.out.print("字符串：" + newStr + "\t\t"); 
                    }else if(o instanceof Long){ 
                        Long s = (Long) o; 
                        System.out.print("浮点值：" + s + "\t\t"); 
                    }else if(o instanceof Integer){ 
                        Integer s = (Integer) o; 
                        System.out.print("整形值：" + s + "\t\t"); 
                    }else{ 
                        System.out.print("未知型：" + o + "\t\t"); 
                    } 
                } 
                System.out.println(); 
            } 
        } catch (Exception e) { 
            e.printStackTrace(); 
        }        

有用JDBC读数据库的，参考下这个，写的不错
