Brief description
Because I have never done login persistence, usually logout is a direct jump, regardless of session or session, so when considering this operation today, I intend to directly control it through js; after studying for a while, I want to use the database Store a state value for control, but it feels too cumbersome, and then suddenly thought that you can link to the login page through a jump link, and then delete the session directly on the login page, which is convenient and fast, so record it.
achieve
- Exit link
<li>
<a href="../login.jsp" class="logout"><i class="iconfont icon-power-off"></i><span>退出</span></a>
</li>
- Clear the specified session
// 退出清除指定session
<%
session.removeAttribute("myUser");
%>
// 退出清除全部session
<%
session.invalidate();
%>
Show results
