Set navigation bar selected status __ navigation bar

Stupid way to set navigation bar selected state
Because my navigation bar is a global page, other pages are introduced to this page, so you cannot use the normal <li class= "active" ></li> to set the selected state
Finally, I think of a stupid way

1.jsp Page

<li class= "${activi1}><a href= aa.action" ><i class= "fa fa-bars" ></i> Overview </a></li >
<li class= "${activi2}><a href=" bb.action "><i class=" FA fa-table "></i> comprehensive </a> </li>

2.action
SetAttribute when the action is invoked

Public String AA () {
        getrequest (). setattribute ("Activi1", "active");
        return "index.jsp";
    }
