郭小洋的方法

//public class EncodingFilter implements Filter {

// private String charEncod;

//

// public void destroy() {

//

//

// }

//

// public void doFilter(ServletRequest request, ServletResponse response,

// FilterChain filterChain) throws IOException, ServletException {

//

// request.setCharacterEncoding(charEncod);

// filterChain.doFilter(request, response);

// }

//

// public void init(FilterConfig config) throws ServletException {

// charEncod = config.getInitParameter("encoding");

// }

//

//}

网上找的方法

public class EncodingFilter implements Filter {

public void destroy() {

}

protected String encoding = null ;

public void init(FilterConfig filterConfig) throws ServletException {

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

}

public void 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。
