The example in this article describes the method of reading and writing Cookie records in Java. Share it with everyone for your reference. The details are as follows:

Write Cookie, the value of cookie can be 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);

Read Cookie:

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();
   }
 }
}
Copy after login
