與Spring MVC的

Question

其實我的設置這是從bean類中獲得方法modelandveiw的屬性，並試圖讓其他modelandveiw方法方法屬性，但在

rs.getAttribute越來越空值（「客戶ID」處理會話）

。請幫幫我。

@RequestMapping(value ="/insert",method= RequestMethod.Post) 

    public ModelAndView inserData(@ModelAttribute SavingBean savingBean,HttpServletRequest rs) { 

    HttpSession session = rs.getSession(); 

    if (savingBean != null) 
    SavingBean saving = persionalService.insertData(savingBean); 

    int a = saving.getCustomerId(); 

    rs.setAttribute("customerId",a); 


    System.out.println(saving.getDisgnProf()); 

    List<SavingBean> list = new ArrayList<SavingBean>(); 
    list.add(saving); 

    return new ModelAndView("welcome","list", list); 



} 



    @RequestMapping(value ="/insertdata",method= RequestMethod.Post) 

public ModelAndView check (@ModelAttribute SavingBean savingBean,HttpServletRequest rs) { 


    System.out.println(savingBean.getFirstName()); 

    HttpSession session = rs.getSession(); 



    System.out.println("abhishek" + rs.getAttribute("customerId")); 



return null ; 

}

Answer 1

你不把或在此代碼獲取從會話什麼。您正在從rs中獲取屬性，rs是請求，而不是會話。

Answer 2

是的，你正在把它放在請求rs，把它放在會話中，而你會選擇它
