Question

我想从控制器方法获取会话值到jsp。有人可以帮助我如何做到这一点

controller.java

@RequestMapping(value="customerLogin.do", method=RequestMethod.POST)
public String customerLogin(HttpServletRequest request, HttpSession session,HttpServletResponse response) throws SQLException, IOException{
String customerEmail=request.getParameter("customerEmail");
String password= request.getParameter("customerPassword");
Boolean isLoggedIn=false;
Customer customer= serviceInter.logincustomer(customerEmail, password);
if(customer!=null){
    isLoggedIn=true;
}
response.getWriter().write(new Gson().toJson(isLoggedIn));
session.setAttribute("customerInfo", customer);
return null;
}

我需要在这里获得该值

Hello＆lt;客户名称＆GT;

Answer 1

您可以使用以下声明来获取它：

Customer customer = (Customer) session.getAttribute("customerInfo");
//System.out.println(customer.getFirstName());

Answer 2

您如何在JSP中检索？你得到的错误是什么？

${customerInfo.name} 
OR 
Customer customer = (Customer) session.getAttribute("customerInfo");

第二个选项：您还可以使Controller成为会话范围。

@Controller
@Scope("session")
public class SessionScopedController
