when the foreground calls the background interface, you need to take some parameters in the request header, and the processing done in the background is a simple page jump. For example,
@ RequestMapping ("/ a")
public String index () {
return "index";}
how do I request from the receptionist?
I have always thought that the parameters of header cannot be put. After using ajax, I will return the contents of the index page to
urgent!
send back the path to be redirected directly, and the receptionist will receive the path and take it with localtion= "path".
if you need page redirection, use form, background to redirect directly
this simple jump does not need to go through the background
pass parameters:
<c:set var="menu_item" value="code" scope="request" />
<c:import url="../tiles/header.jsp" />receive parameters:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<header>
<div>${menu_item}</div>
</header>
