  <filter>
   <filter-name>SetCharacterEncoding</filter-name>
   <filter-class>com.gh.filters.SetCharacterEncodingFilter</filter-class>
   <init-param>
      <param-name>encoding</param-name>
      <param-value>utf-8</param-value>
    </init-param>
    </filter>
    <filter-mapping>
   <filter-name>SetCharacterEncoding</filter-name>
   <url-pattern>/*</url-pattern>
  </filter-mapping>SetCharacterEncodingFilter class public class SetCharacterEncodingFilter implements Filter { private String encoding;
 private FilterConfig filterConfig = null;
 
 public void destroy() {
  this.encoding = "utf-8";
  this.filterConfig = null;  }  public void doFilter(ServletRequest request, ServletResponse response,
   FilterChain chain) throws IOException, ServletException {
  request.setCharacterEncoding(this.encoding);
  chain.doFilter(request, response);
  System.out.println("doFilter-------"+ this.encoding);
 
 }  public void init(FilterConfig filterConfig) throws ServletException {
  this.encoding = filterConfig.getInitParameter("encoding");
 }
