数据技术都能四世同堂，凭什么开发 30 岁就要被干掉？>>> 
@ResponseBody
@RequestMapping("/logout")
public Json logout(HttpSession session,HttpServletRequest request,HttpServletResponse response) {
Json j = new Json();
if (session != null) {
// session.invalidate();
session.removeAttribute("U");
}
Cookie[] cookies = request.getCookies();
if (cookies != null) {
for (Cookie cookie : cookies) {
if ("userCookie".equals(cookie.getName())) {
cookie.setValue("");
cookie.setMaxAge(0);
response.addCookie(cookie);
}
}
}
j.setSuccess(true);
j.setMsg("注销成功！");
return j;
}
这是注销了之后的cookie 没有value了
再看下面的拦截程序：
public class PermissionInterceptor implements HandlerInterceptor {
@Override
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {
String requestUri = request.getRequestURI();
String contextPath = request.getContextPath();
String url = requestUri.substring(contextPath.length());
if (excludeUrls.contains(url)) {
return true;
}
HttpSession session = request.getSession();
User u = (User) session.getAttribute("U");
if (null==u) {
Cookie[] cookies = request.getCookies();
if (cookies!=null && cookies.length>0) {
for (Cookie cookie : cookies) {
if ("userCookie".equals(cookie.getName())) {
String name = cookie.getValue();
if (BaseUtil.isEmpty(name)) {
String[] ss = name.split(",");
if (userService.exsit("name", ss[0].trim(), "pwd", ss[1].trim())) {
u = userService.findEntity("name", ss[0].trim(), "pwd", ss[1].trim());
session.setAttribute("U", u);
break;
}
}
}
}
}
}
}
Cookie[] cookies = request.getCookies();这里获取到的cookie，截图为：
我有点不明白 ，还是我太菜鸟了。
为什么两个cookie 不一样，请指导？？？？？
