我正在从我的 LogoutServlet 中的会话中删除一个属性。在另一个 servlet(LogoutCheckServlet) 中，我试图获得相同的属性，但它仍然存在。请帮我找出同样的原因。
注销Servlet
公共类 LogoutServlet 扩展 HttpServlet {
/**
*
*/
private static final long serialVersionUID = 1L;
protected void doPost(HttpServletRequest request, HttpServletResponse response) {
HttpSession session= request.getSession(false);
if(session.getAttribute("userInfo")!=null) {
System.out.println("In Logout");
session.removeAttribute("userInfo");
session.invalidate();
System.out.println("In Logout");
}
try {
response.sendRedirect("http://localhost:8080/loginpoc/JSP/Login.jsp");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
