1. index.jsp中包含有iframe
登陸成功後進入此頁面進行session值判斷,若無則使用jsp跳轉方法跳到登陸頁login.jsp
jsp跳轉方法有以下幾種:
response.setHeader("refresh","1;url='../login.jsp'");
response.sendRedirect("../login.jsp");
<jsp:forward page="../login.jsp"></jsp:forward>
<jsp:include flush="true" page="../login.jsp"></jsp:include>
2. 在login.jsp中設置如下
<script type="text/javascript">
function checkParent(){
if(window.parent.length>0){
window.parent.location="login.jsp";
}
</script>
<body οnlοad="checkParent();">
.....................................
</body>
只要session無值就會自動跳出框架且轉到登陸頁
