一、异常现象

更改了hadoop的配置文件：core-site.xml 和 mapred-site.xml 之后，重启hadoop 和 hbase 之后，发现hbase日志中抛出了如下异常：

[java]处理utf-8 bom字符串的bom头

char[] bomChar = "带bom的字符串".toCharArray();//转为char数组 char[] noneBomchar = new char[bomChar.length - 1];//数组第一个元素是bom头，去掉它 for (int j = 0; j < noneBomchar .length; j++) { noneBomchar [j] = bomChar[j + 1]; } String first = String.valueOf(noneBomchar );//重组转String 例如：例子中的字符串中有bom头处理之后：

我们可以使用data-作为前缀来设置我们所需要的自定义数据属性。使用此属性可以存放一些我们所需要的数据，代码如下: 1 < a href = "javascript:" data-url = "softwhy.com" data-webname = "蚂蚁部落" >蚂蚁部落</ a > 上面代码中，以data-为前缀就是自定义数据属性，属性值就是存放的数据。浏览器兼容: （1）.IE8和IE8以上浏览器支持此属性。（2）.谷歌浏览器支持此属性。（3）.火狐浏览器支持此属性。（4）.opera浏览器支持此属性。（5）.safria浏览器支持此属性。命名规则: （1）.数据属性要以data-开头。（2）.属性名中的字符都是小写，并且在前缀 "data-" 之后必须有至少一个字符。（3）.属性值可以是任意字符串。可以利用自定义属性进行css匹配和相关javascript操作。使用自定义属性作为选择器代码如下: 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 ...
