网上找的方法

publicclass EncodingFilter implements Filter {

       publicvoid destroy() {

       }

 

       protected String encoding = null;

 

       publicvoid init(FilterConfig filterConfig) throws ServletException {

              this.encoding = filterConfig.getInitParameter("encoding");

       }

 

       publicvoid doFilter(ServletRequest request, ServletResponse response,

                     FilterChain chain) throws IOException, ServletException {

              request.setCharacterEncoding(encoding);

              response.setContentType("text/html;charset=" + encoding);

              chain.doFilter(request, response);

       }

 

}

 

Web.xml文件

说明：把以下代码粘贴web.xml文件的空白处，它是独立的。

<filter>

        <filter-name>encoding</filter-name>

        <filter-class>jfis.util.EncodingFilter</filter-class>

        <init-param>

                     <param-name>encoding</param-name>

                     <param-value>GBK</param-value>

              </init-param>

 </filter>

 <filter-mapping>

        <filter-name>encoding</filter-name>
