Java method of reading and writing Cookie records

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();
   }
 }
}

I hope this article will be helpful to everyone’s Java programming.
