目录一、功能分析二、controller三、service四、缓存工具类五、拦截器修改六、tokenService修改一、功能分析个人中心我们要支持当前登录用户的信息展示以及对信息的编辑。并且展示获得用户信息详情的时候还需要加入redis缓存。二、controlleroj-modules/oj-friend/src/main/java/com/yj/friend/controller/user/UserController.java接口/** * 获取当前用户详情 * return */GetMapping(/detail)publicRUserVOdetail(){returnR.success(userService.detail());}/** * 编辑当前用户信息 * param userUpdateDTO * return
