cookie 设置 httpOnly属性

cookie 设置 httpOnly属性防止js读取cookie.

建立filter拦截器类

CookieHttpOnlyFilter

** @author hnnc* @author $Author$* @version $Id$ */public class CookieHttpOnlyFilter implements Filter {    /** {@inheritDoc} **/    public void doFilter(ServletRequest request, ServletResponse response,            FilterChain chain) throws IOException, ServletException {        if (!(request instanceof HttpServletRequest)) {            chain.doFilter(request, response);            return;        }        HttpServletRequest httpReq = (HttpServletRequest) request;        HttpServletResponse httpResp = (HttpServletResponse) response;        Cookie[] cookies = httpReq.getCookies();        if (cookies != null) {            Cookie cookie = cookies[0];            if (cookie != null) {                HttpSession session = httpReq.getSession();                if (session != null) {                    String sessionId = session.getId();                    // httpの设置                    httpResp.addHeader("Set-Cookie", "JSESSIONID=" + sessionId                            + "; Path=/admin; HttpOnly");                    // httpsの设置//                    httpResp.addHeader("Set-Cookie", "JSESSIONID=" + sessionId//                            + "; Path=/admin;Secure; HttpOnly");                }            }        }        chain.doFilter(httpReq, httpResp);                    }    /** {@inheritDoc} **/    public void destroy() {    }    /** {@inheritDoc} **/    public void init(FilterConfig filterConfig) throws ServletException {    }}

web.xml中配置拦截器
