servlet用session传int类型值到jsp页面

Servlet：

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

HttpSession session=request.getSession();


int id=Integer.parseInt(request.getParameter("id"));
session.setAttribute("id", id+"");//隐式把int转String
request.getRequestDispatcher("an.jsp").forward(request, response);
}

jsp:

<%
	int id=Integer.parseInt((String)session.getAttribute("id"));//接受从控制器上设置好的id值,把String转化为int
	out.print(id);
	
 %>
