springMVC 中获取session方法

存储session方法
方法一：可以直接在方法的参数中引入,其中session也可以通过request获得

方法二：通过@SessionAttributes注解进行设置

@Controller
@RequestMapping(value="/spittles")
@SessionAttributes("name")
public class SpittlesController {
    @RequestMapping(value="/model",method=RequestMethod.GET)    
    public String personInfo1(Model model,HttpSession httpSession,HttpServletRequest request){
        String personList = "返回字符串";
        httpSession.setAttribute("nickname","Frank");
        HttpSession session = request.getSession();
        session.setAttribute("age","14");
        model.addAttribute("name",personList);
        return "personList";
    }
}

获取session方法

方法一：可以直接在方法的参数中引入,其中session也可以通过request获得

JAVA代码

@RequestMapping(value="/session",method={RequestMethod.GET,RequestMethod.POST})
    public String getSession(HttpSession httpSession){

        System.out.println(httpSession.getAttribute("name"));
        return"registerForm";
    }

方法二：使用 @Autowired 注入HttpSession，或HttpServletRequest来获取session

JAVA代码

@Autowired
HttpServletRequest request;
@RequestMapping(value="/session",method={RequestMethod.GET,RequestMethod.POST})
public String getSession(){

    HttpSession httpSession = request.getSession();
    System.out.println(httpSession.getAttribute("name"));
    return"registerForm";
}
