页面乱码问题，高手请帮忙！
<%@ page pageEncoding= "UTF-8 "%>
<%@ page contentType= "text/html;charset=UTF-8 "%>
<%@ taglib uri= "/tags/struts-bean " prefix= "bean " %>
<%@ taglib uri= "/tags/struts-html " prefix= "html " %>
<%@ taglib uri= "/tags/struts-logic " prefix= "logic " %>
<%@ taglib uri= "/tags/struts-tiles " prefix= "tiles " %>
<%@ taglib uri= "/tags/struts-nested " prefix= "nested "%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN ">
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=UTF-8 ">
<title> TESTSTRUTS </title>
</head>
<body>
<html:form action= "/hello ">
用户帐号： <html:text property= "userName "/> <html:errors property= "userName "/> <br/>
用户密码： <html:text property= "userPasswrd "/> <html:errors property= "userPasswrd "/> <br/>
<html:submit value= "提交 "/> <html:cancel value= "取消 "/>
</html:form>
<logic:present name= "personbean " scope= "request ">
<h1>
<bean:message key= "hello.jsp.page.hello "/>
<bean:write name= "personbean " property= "userName "/>
</h1>
<h2>
<bean:write name= "personbean " property= "userPasswrd "/>
</h2>
</logic:present>
</body>
</html>
结果是：“用户名称：”变成了“鐢ㄦ埛甯愬彿锛�”
请问是什么原因？查了很多资料了！没有解决！
------解决方案--------------------
1.编码问题:
(1)首先确定JSP页面头部是否有: <%@ page contentType= "text/html; charset=GBK " %>
(2)类似这样的转码:
String param= new String(request.getParameter( "param ").getBytes( "ISO-8859-1 "), "GBK ");
(3)添加filter字符过滤器,具体做法:
先添加类:
import javax.servlet.Filter;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.FilterChain;
import java.io.IOException;
import org.apache.log4j.Logger;
import java.net.URLEncoder;
/** *//**
* 请求中中文字符串过滤类
*/
public class SetEncodingFilter
implements Filter ...{
private Logger logger=Logger.getLogger(this.getClass());
public void init(FilterConfig filterConfig) throws ServletException ...{
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException ...{
logger.i
<%@ page pageEncoding= "UTF-8 "%>

<%@ taglib uri= "/tags/struts-logic " prefix= "logic " %>

用户密码： <html:text property= "userPasswrd "/> <html:errors property= "userPasswrd "/> <br/>

</html:form>

<h1>
