web.xml添加攔截器:nginx

只要使用標準的servlet api調用session,在底層就會經過Spring Session獲得的,而且會存儲到Redis或其餘你所選擇的數據源中。web
這裏是我寫的一個demo:redis
/** * @author fengzp * @date 17/2/23下午3:19 * @email fengzp@gzyitop.com * @company 廣州易站通計算機科技有限公司 */ @Controller @RequestMapping(value = "index") public class IndexController { private final Gson gson = new GsonBuilder().setDateFormat("yyyyMMddHHmmss").create(); @RequestMapping(value = "login") public String login(HttpServletRequest request, String username){ request.getSession().setAttribute("user", gson.toJson(new User(username,"123456"))); return "login"; } @RequestMapping(value = "index") public String index(HttpServletRequest request, Model model){ User user = gson.fromJson(request.getSession().getAttribute("user").toString(), User.class); model.addAttribute("user", user); return "index"; } }
index.jsp:spring
第一個tomcatapi
<html> <body> <h2>Hello World!</h2> <p>${user.username}</p> </body> </html>
第二個tomcatspring-mvc
<html> <body> <h2>Hello World! i am the second!</h2> <p>${user.username}</p> </body> </html>
這裏利用上一篇nginx負載配置的兩個tomcat來測試。
首先訪問 http://192.168.99.100/feng/index/login.htm?username=nginx
來觸發生成session。tomcat
查看redis,發現session已經保存到redis。
session
訪問 http://192.168.99.100/feng/index/index.htm
來讀取session, 並刷新屢次。
mvc
發如今負載的狀況下讀取session沒問題,而且是同一個session,成功實現負載+session共享!
