从jsp表单里得到的中文是乱码
我在jsp里设置了
<META   http-equiv=content-type   content= "text/html;   charset=utf-8 ">

在java程序后台取数据时也设置了
request.setCharacterEncoding( "utf-8 ");

可是在调试时发现，java中取到的中文数据就是乱码。

请高手指点.



------解决方案--------------------
容器 jsp页面 数据库 都用统一的编码

加一个 Filter

web.xml中配置

<filter>
<filter-name> Set Character Encoding </filter-name>
<filter-class>
com.smyl.init.CharacterEncodingFilter
</filter-class>
<init-param>
<param-name> encoding </param-name>
<param-value> UTF-8 </param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name> Set Character Encoding </filter-name>
<url-pattern> /* </url-pattern>
</filter-mapping>
