public boolean preHandle(HttpServletRequest req, HttpServletResponse resp, Object handler) {
    Map<String, Object> data = .....;
    return true;
}

@RequestMapping(value = "/user/{uid}", method = RequestMethod.PUT)
public JsonResult updateById(@PathVariable Integer uid) {
    这里能否用到 data ?
    return userService.updateById(uid);
}

可以, 通过 requestmap
`this.setRequestAttribute(req, "", "");`
`@RequestAttribute`
