struts2升级之后jsp到action传值出现乱码问题

web.xml中添加

 <filter>
   <filter-name>encodingFilter</filter-name>
   <filter-class>
   com.xinli.webapp.filter.EncodingConvertFilter 
   </filter-class>
</filter>
<filter-mapping>
   <filter-name>encodingFilter</filter-name>
   <url-pattern>/*</url-pattern> 
</filter-mapping>

filter类：

package com.xinli.webapp.filter;

import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**

public class EncodingConvertFilter implements Filter {
@Override
public void destroy() {

    }
@Override
public void doFilter(ServletRequest req, ServletResponse rsp,
            FilterChain fc) throws IOException, ServletException {
        HttpServletRequest request=(HttpServletRequest) req;
        HttpServletResponse response=(HttpServletResponse) rsp;
        request.setCharacterEncoding("utf-8");
        response.setContentType("text/html;charset=utf-8");
        fc.doFilter(request, response);
    }
@Override
public void init(FilterConfig arg0) throws ServletException {

    }
}
