自定义的filter：
public class ResponseHeaderFilter implements Filter { FilterConfig fc; public void doFilter(ServletRequest req, ServletResponse res,FilterChain chain) throws IOException, ServletException { HttpServletResponse response = (HttpServletResponse) res; for (Enumeration e = fc.getInitParameterNames(); e.hasMoreElements();) { String headerName = (String) e.nextElement(); response.addHeader(headerName, fc.getInitParameter(headerName)); } chain.doFilter(req, response); } public void init(FilterConfig filterConfig) { this.fc = filterConfig; } public void destroy() { this.fc = null; } }
