token通过redis缓存传递过程

登录：loginController
String token=JwtUtil.sign(user.getName(), user.getPwd());
redisTemplateService.set(token, user);
return ResponseDataUtil.success(token,user);
登录返回：login.js
localStorage.setItem(“token”,data.msg);

ajax使用token
url: “DoExercise/judge”,
headers: {“TOKEN”:localStorage.getItem(“token”)},

Controller接受token
User loginUser= redisTemplateService.get(request.getHeader(“TOKEN”),User.class);
answerFrom.setUid(loginUser.getId());
