public class encodingFilter implements Filter {
private FilterConfig config;
private String Encoding="iso8859-1";
public void destroy() {
config=null;
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
request.setCharacterEncoding(Encoding);
chain.doFilter(request, response);
}
public void init(FilterConfig con) throws ServletException {
this.config=con;
String s=config.getInitParameter("Encoding");
if(s!=null)
{
this.Encoding=s;
System.out.println(Encoding);
}
}
}

------解决方案--------------------------------------------------------
在request.setCharacterEncoding(Encoding);
