Pass data through browser to JSP: Spring boot

I'm passing data from my browser to HomeController.java by just changing the URL, URL

My HomeController.java as follows,

    package com.example.demo;

    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpSession;

    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;


    @Controller
    public class HomeController {

        @RequestMapping("home")
        public String home(HttpServletRequest req) {
            HttpSession session=req.getSession();
            String name=req.getParameter("name");
            //Fetch data comming from client
            System.out.println("hi "+name);
            session.setAttribute(name, name);
            return "home";
        }
     }

I'm passing session attribute using session object but how should I fetch that in my JSP file(home.jsp).

my home.jsp looks like :

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
    Welcome ${name}
</body>
</html>

I want to write java code in home.jsp file and use the session object instead of the expression language format. Can anyone tell how to use that session object?

Thanks in advance!

To answer your question directly, you can call your variable from the session object like so :

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
    Welcome <%=session.getAttribute("name")%>
</body>
</html>

Where name is the name of the object stored in your session.

PS : use a Logger instead of System.out
