jsp用过滤器解决中文乱码

定义一过滤器，实现Filtter接口

public class EncodingFilter implements Filter {

@Override
public void destroy() {
// TODO Auto-generated method stub


}


@Override
public void doFilter(ServletRequest req, ServletResponse resp,
FilterChain chain) throws IOException, ServletException {
// TODO Auto-generated method stub
HttpServletRequest request=(HttpServletRequest)req;
HttpServletResponse response=(HttpServletResponse)resp;

request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=UTF-8");

chain.doFilter(req, resp);


}


@Override
public void init(FilterConfig filterConfig) throws ServletException {
// TODO Auto-generated method stub


}

}

web.xml文件中，配置过滤器

  EncodingFilter
  pers.filter.EncodingFilter
