本文实例讲述了Java读写Cookie记录的方法。分享给大家供大家参考。具体如下:
写Cookie ,cookie的value可以使String, list , map,int :

Cookie usernameCookie = new Cookie( "username_" + schoolId, encodedUsername); usernameCookie.setMaxAge( 60 * 60 * 24 * 365 ); response.addCookie(usernameCookie); //设置useriCookie--用于心教育的猜你喜欢课程 Cookie userIdCookie = new Cookie( "userId_" + schoolId, userId); userIdCookie.setMaxAge( 60 * 60 * 24 * 365 ); response.addCookie(userIdCookie); |

HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest(); String userId= null ; Cookie[] cookies = request.getCookies(); //cookies不为空,则清除 if (cookies!= null ) { for (Cookie cookieTemp : cookies){ String cookieIdentity = cookieTemp.getName(); //查找身份串 if (cookieIdentity.equals( "userId_" +schoolId)) { userId=cookieTemp.getValue(); } } } |
希望本文所述对大家的java程序设计有所帮助。
