tomcat7 get请求乱码,求大神解惑呀

在做一个项目时，get请求发送中文参数出现乱码，框架是ssh框架
已经设置了springMVC的过滤器，tomcat中server.xml也已经指定编码，jsp页面也指定了编码，但是发送get请求是还是乱码

web.xml

server.xml

 <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
               URIEncoding="UTF-8"
               useBodyEncodingForURI="true"/>

jsp:

 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 <%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>

这个get需要添加编码，在发送请求的地方把中文参数staff改为encodeURI(encodeURI(staff))，
在后台处理的地方进行解码，URLDecoder.decode(staff,"UTF-8")
