Question

我想从controller方法获取到jsp的会话值。有人能帮我怎么做吗

控制器。爪哇

@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;
}

让我在这里获取该值

您好<；客户名称>

Answer 1

如何在JSP中检索？ 您得到的错误是什么

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

第二个选项：您还可以将控制器设置为会话范围

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

Answer 2

您可以使用以下语句获得它：

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