我想问一下怎样解决这个问题啊。。。。。
这是我的EncodingFilter类：
public class EncodingFilter {
public void destroy() {
// TODO Auto-generated method stub
System.out.println("destory");
}
/**
* 对请求进行编码
*/
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpRequest=(HttpServletRequest)request;
httpRequest.setCharacterEncoding("UTF-8");
//HttpServletResponse httpresponse=(HttpServletResponse)response;
//httpresponse.setCharacterEncoding("GB2312");
//将请求继续丢给下面的过滤器或者是servlet做请求处理
System.out.println("doFilter");
chain.doFilter(request, response);
}
public void init(FilterConfig arg0) throws ServletException {
System.out.println("init");
}
}
下面是我的xml中关于filter的一段文档：
<filter>
<filter-name>encodingFilter</filter-name>
