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 EncodingFiter implements Filter{

    @Override
    public void destroy() {
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response,
            FilterChain chain) throws IOException, ServletException {
        HttpServletRequest req=(HttpServletRequest) request;
        req.setCharacterEncoding("UTF-8");
        HttpServletResponse res=(HttpServletResponse) response;
        res.setCharacterEncoding("UTF-8");
        chain.doFilter(req, res);
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }
   
}
