jsp/servlet乱码解决问题

今天做了个jqury+serlet+jsp的小例子，结果出现点小问题，参数乱码，返回信息到的页面也是乱码，于是我开始对接受的参数开始进行判断，结果是乱码，我在jsp页面设置的类型utf-8,
String username = new String(request.getParameter("name").getBytes("ISO-8859-1"),"GBK");
通过这种方式我把从页面接受的参数转换成了汉字，问题解决
第二个问题就是从服务器到页面乱码的问题
这个问题就直接把PrintWriter out = response.getWriter(); response参数单独转换到页面的编码方式就可以了response.setCharacterEncoding("UTF-8");
乱码问题如果用filter过滤器来操作可能会方便点
web.xml
filter>
filter-name>Set Character Encoding /filter-name>
filter-class>
cn.com.shxt.util.filter.SetCharacterEncodingFilter
/filter-class>
init-p aram>
param-name>encoding /param-name>
param-value>UTF-8 /param-value>
/init-p aram>
/filter>
