I can get cookie in JSP like this:
我可以像这样在 JSP 中获取 cookie：
Cookie[] cookies = request.getCookies();
if (cookies != null) {
for (Cookie cookie : cookies) {
//work with cookies
}
}
But I wonder if I can get it with jsp:useBean (or something else)? May be like this:
但是我想知道我是否可以通过 jsp:useBean （或其他东西）获得它？可能是这样的：
<jsp:useBean id="myCookie" class="javax.servlet.http.Cookie" scope="request" beanName="cookieName"/>
...
<div class="${myCookie.value == "true" ? "class1" : "class2"}"></div>
Thx for your answers!
